-## Project Overview
-
-CRAIC (Camera-Robot AI Control System) — Competition code for the China Robot and Artificial Intelligence Competition (中国机器人及人工智能大赛), Robot Task Challenge (Small Desktop Level).
-
-**Hardware**: ESP32-S3-WROOM-1-N16R8 with OV2640 camera, 6-DOF mechanical arm with Feettech SCS/STS serial servos.
-
-**Architecture**: Three-tier system communicating via UDP port 8888:
-1. **ESP32-S3 firmware** (`jxbeye/`) — Dual-core camera streaming + UDP command receiver
-2. **ROS 2 teleop** (`ros2/src/udp_teleop/`) — Keyboard control node for chassis and arm
-3. **Python tools** (`tools/`) — Standalone control scripts with inverse kinematics
-
-## Build & Run Commands
-
-### ESP32-S3 Firmware
-
-```bash
-cd jxbeye
-pio run -t upload          # Build and flash firmware
-pio device monitor         # Serial monitor (1000000 baud)
-```
-
-**First boot**: ESP32 creates AP `ESP32-S3-Camera` (password `12345678`), access web UI at `http://192.168.4.1`.
-
-**WiFi configuration via serial**: Send `WIFI:SSID:PASSWORD` to configure station mode.
-
-### ROS 2 Teleop
-
-```bash
-# Build (from ros2/ directory)
-conda activate ros2_humble
-colcon build --symlink-install --packages-select udp_teleop
-source install/setup.bash
-
-# Run keyboard control
-ros2 run udp_teleop keyboard_control \
-    --ros-args --params-file src/udp_teleop/config/params.yaml
-
-# Override target IP
-ros2 run udp_teleop keyboard_control \
-    --ros-args -p udp_ip:=192.168.4.1 -p udp_port:=8888
-```
-
-**Keyboard mappings**:
-- Chassis: W/S (forward/back), A/D (strafe), Q/E (rotate)
-- Arm: ↑/↓ (height), 2-6 (select joint), ←/→ (adjust angle)
-
-**Important**: Must use `ros2 run`, not `ros2 launch` — the `stdin` keyboard backend requires an interactive terminal.
-
-### Python Arm Control Tools
-
-```bash
-# Direct joint command with interpolation
-python tools/udp_control.py joints \
-    --height -100 --j2 10 --j3 20 --j4 30 \
-    --duration 1.0 --rate 20
-
-# Cartesian pose mode (uses inverse kinematics)
-python tools/udp_control.py pose \
-    --x 150 --y 50 --z -100 --phi 45 \
-    --duration 1.0
-
-# Dry run (print commands without sending)
-python tools/udp_control.py pose --x 200 --y 0 --z -50 --phi 0 --dry-run
-
-# Camera frame capture
-python tools/camera_capture.py --ip 192.168.4.1
-python tools/camera_capture.py --scan  # Auto-detect camera on subnet
-```
-
-### UDP Testing
-
-```bash
-# Start echo server
-python tools/udp_server.py
-
-# Send test commands
-echo 'XYW:100:0:0:XZHY' | nc -u 192.168.4.1 8888
-echo 'JXB:-100:10:20:30:0:0:0:0:EZHY' | nc -u 192.168.4.1 8888
-```
-
-## Architecture Details
-
-### ESP32-S3 Dual-Core Design
-
-- **Core 0**: Camera capture loop (OV2640 → JPEG)
-- **Core 1**: WiFi streaming (MJPEG HTTP server on port 80)
-- **AsyncUDP**: Non-blocking UDP command receiver runs on Core 1, handled via interrupt callbacks
-
-The dual-core split ensures camera capture never blocks on WiFi transmission. UDP commands are processed asynchronously and do not interfere with streaming.
-
-### UDP Protocol
-
-All commands are ASCII text ending with terminator (varies by command type):
-
-```
-# Chassis control (XYZ cartesian velocity)
-XYW:<X_speed>:<Y_speed>:<W_angular>:XZHY\n
-
-# Arm control (6 motors: height, J2-J6)
-JXB:<height>:<J2>:<J3>:<J4>:<J5>:<J6>:0:0:EZHY\n
-
-# Laser control
-LASERON\n
-LASEROFF\n
-
-# Serial passthrough (any payload with ZHY or \n terminator)
-<payload>ZHY\n
-```
-
-**Critical**: The ESP32 firmware parses based on terminator suffix, not command prefix.
-
-### Mechanical Arm Coordinate System & Kinematics
-
-**Coordinate frame**: Base frame with Z-axis pointing UP (not down). Origin at the bottom of the J1 linear slide.
-
-**Height coordinate (d1)**:
-- User-facing coordinate: `-290 mm` (bottom) to `0 mm` (top)
-- Physical meaning: vertical position of J2 relative to base origin
-- **Z-up convention**: positive d1 = higher position
-
-**Planar joints (J2, J3, J4)**:
-- All three rotate around vertical Z-axis in the XY plane
-- J2 is base rotation, J3/J4 are elbow/wrist
-- TCP yaw angle `phi = J2 + J3 + J4` (additive)
-
-**Geometry parameters** (see `docs/arm.md` for full derivation):
-- `L1 = 125 mm`: J2-J3 link length
-- `L2 = 125 mm`: J3-J4 link length  
-- `x4 = 110 mm`: J4-to-TCP horizontal offset
-- `z4 = 80 mm`: J4-to-TCP vertical offset (variable: 55mm when gripper down, -100mm when up)
-
-**Zero offsets**: Physical mechanical zero does not align with math zero (straight line):
-- `J2_zero = 3°`, `J3_zero = 7°`, `J4_zero = 25°`
-- UDP command angles = math angles + zero offsets
-
-**Inverse kinematics** (`tools/udp_control.py`):
-- Solves for joint angles given TCP pose `(x, y, z, phi)`
-- Uses standard 2-link planar arm solution (atan2-based)
-- Two solutions: `--elbow-up` vs default elbow-down
-- Validates workspace limits and singularity checks
-- See `docs/arm.md` for full mathematical derivation
-
-**State persistence**: `tools/.udp_control_state.json` caches last sent joint command. This enables smooth interpolated motion from previous position without re-homing. Use `--no-state-cache` to disable.
-
-### ROS 2 Keyboard Backend Selection
-
-The `udp_teleop` node supports three keyboard input backends:
-
-- `stdin` (default on Linux/macOS): Terminal raw mode, zero dependencies, **requires interactive terminal**
-- `pynput`: Cross-platform library, works in background
-- `win_poll`: Windows-specific Win32 API polling
-
-Backend auto-selected by platform. Override with `keyboard_backend` parameter in `config/params.yaml`.
-
-**Limitation**: `stdin` backend fails when launched via `ros2 launch` because child processes lack TTY. Always use `ros2 run` for interactive keyboard control.
-
-### Camera Capture Tool Auto-Detection
-
-`camera_capture.py` implements subnet scanning and ESP32 identification:
-
-1. Probes common DHCP IPs on local subnet (`x.x.x.1`, `x.x.x.100-110`, etc.)
-2. Verifies ESP32 by checking `/status` endpoint for JSON keys `capture_fps` and `has_client`
-3. Falls back to full subnet scan if not found in common range
-4. Connects to `/stream` MJPEG endpoint, parses multipart frames, extracts first valid JPEG (SOI `0xFFD8` to EOI `0xFFD9`)
-
-Use `--scan` to force full subnet scan, or `--ip` to skip detection.
-
-## Environment Setup
-
-### ROS 2 Humble via Conda (robostack)
-
-```bash
-# Create environment (one-time)
-conda create -n ros2_humble -c robostack-staging -c conda-forge ros-humble-desktop
-conda activate ros2_humble
-conda install -c robostack-staging -c conda-forge colcon-common-extensions
-pip install pynput
-
-# Every session
-conda activate ros2_humble
-cd ros2
-source install/setup.bash  # After first colcon build
-```
-
-**Alternative**: Native apt installation on Ubuntu 22.04 — see `ros2/README.md`.
-
-### PlatformIO ESP32
-
-```bash
-pip install platformio
-cd jxbeye
-pio pkg install  # Install dependencies
-```
-
-**Board configuration** (`platformio.ini`):
-- Custom board definition: `esp32-s3-wroom-1-n16r8`
-- PSRAM: Octal mode (`board_build.psram_type = octal`)
-- Flash: 16MB QIO mode at 80MHz
-- Partition table: `default_16MB.csv`
-
-## Important Files
-
-### Configuration
-
-- `jxbeye/platformio.ini` — ESP32 build config (PSRAM settings critical)
-- `ros2/src/udp_teleop/config/params.yaml` — ROS node parameters (IP, speeds, steps)
-- `tools/.udp_control_state.json` — Cached arm joint state for interpolation
-
-### Documentation
-
-- `docs/arm.md` — Full inverse kinematics derivation with LaTeX equations
-- `README.md` — Project overview and quick start
-- `ros2/src/udp_teleop/README.md` — ROS package details and keyboard mappings
-
-### Core Implementations
-
-- `jxbeye/src/main.cpp` — ESP32 dual-core firmware entry point
-- `ros2/src/udp_teleop/udp_teleop/keyboard_control.py` — ROS keyboard node
-- `tools/udp_control.py` — Standalone arm controller with full IK solver
-- `tools/camera_capture.py` — MJPEG stream frame extractor
-
-## Common Tasks
-
-**Change arm geometry parameters**: Edit constants in `tools/udp_control.py` (`DEFAULT_L1`, `DEFAULT_L2`, `DEFAULT_X4`, `DEFAULT_Z4`) or pass as CLI args.
-
-**Modify joint limits**: Edit `DEFAULT_*_MIN/MAX` in `tools/udp_control.py` or use `--height-min`, `--j2-max`, etc.
-
-**Adjust interpolation smoothness**: Change `--duration` (total time) and `--rate` (Hz) in `udp_control.py`. Default is 1.0s at 20Hz = 20 steps.
-
-**Debug UDP protocol**: Use `tools/udp_server.py` as echo server, point ROS/tools at `127.0.0.1:8888` to inspect raw commands.
-
-**Test kinematics without hardware**: Use `--dry-run` flag with `udp_control.py` to print UDP commands without sending.
-
-**Verify IK correctness**: Use `--show-fk` flag to compute forward kinematics of the solved joint angles and compare to target pose.
-
-## Dataset
-
-The `dataset.zip` and `dataset/` directory contain competition-specific training data (exact format unknown from structure alone).

-     Y (左)
-```
-
-- 原点：J1 滑轨底部
-- d1 范围：[-290, 0] mm（负值表示在基准面以下）
-
-## 正运动学（FK）
-
-已知关节状态 → 计算 TCP 位姿
-
-### 输入
-
-- `d1`: 高度（J1 线性位移）
-- `θ2, θ3, θ4`: J2/J3/J4 角度（度）
-
-### 输出
-
-- `(x, y, z)`: TCP 位置（mm）
-- `φ`: TCP 偏航角（度）
-
-### 推导
-
-**步骤 1**：计算 J4 中心位置（XY 平面）
-
-J2 和 J3 形成二连杆机构：
-
-$$
-x_{j4} = L_1 \cos\theta_2 + L_2 \cos(\theta_2 + \theta_3)
-$$
-
-$$
-y_{j4} = L_1 \sin\theta_2 + L_2 \sin(\theta_2 + \theta_3)
-$$
-
-**步骤 2**：计算 TCP 偏航角
-
-$$
-\phi = \theta_2 + \theta_3 + \theta_4
-$$
-
-**步骤 3**：计算 TCP 位置
-
-从 J4 中心沿 φ 方向偏移 x4，垂直偏移 z4：
-
-$$
-x = x_{j4} + x_4 \cos\phi
-$$
-
-$$
-y = y_{j4} + x_4 \sin\phi
-$$
-
-$$
-z = d_1 - z_4
-$$
-
-### Python 实现
-
-```python
-def forward_kinematics(d1, theta2_deg, theta3_deg, theta4_deg, L1=125, L2=125, x4=110, z4=80):
-    """正运动学"""
-    theta2 = math.radians(theta2_deg)
-    theta3 = math.radians(theta3_deg)
-    theta4 = math.radians(theta4_deg)
-    phi = theta2 + theta3 + theta4
-    
-    # J4 中心
-    x_j4 = L1 * math.cos(theta2) + L2 * math.cos(theta2 + theta3)
-    y_j4 = L1 * math.sin(theta2) + L2 * math.sin(theta2 + theta3)
-    
-    # TCP 位置
-    x = x_j4 + x4 * math.cos(phi)
-    y = y_j4 + x4 * math.sin(phi)
-    z = d1 - z4
-    
-    return x, y, z, math.degrees(phi)
-```
-
-## 逆运动学（IK）
-
-已知 TCP 目标位姿 → 计算关节角度
-
-### 输入
-
-- `(x, y, z)`: 目标位置（mm）
-- `φ`: 目标偏航角（度）
-
-### 输出
-
-- `d1`: 高度
-- `θ2, θ3, θ4`: 关节角度（度）
-
-### 推导
-
-**步骤 1**：计算 J4 中心目标位置
-
-从 TCP 位置反向计算 J4 位置：
-
-$$
-x_{j4} = x - x_4 \cos\phi
-$$
-
-$$
-y_{j4} = y - x_4 \sin\phi
-$$
-
-$$
-z_{j4} = z + z_4
-$$
-
-$$
-d_1 = z_{j4}
-$$
-
-**步骤 2**：计算平面距离
-
-$$
-r = \sqrt{x_{j4}^2 + y_{j4}^2}
-$$
-
-**步骤 3**：求解 θ3（余弦定理）
-
-二连杆机构的标准解法：
-
-$$
-\cos\theta_3 = \frac{r^2 - L_1^2 - L_2^2}{2L_1L_2}
-$$
-
-检查工作空间：
-
-$$
--1 \leq \cos\theta_3 \leq 1 \quad \Rightarrow \quad |L_1 - L_2| \leq r \leq L_1 + L_2
-$$
-
-否则目标超出工作空间。
-
-有两个解（肘部朝上 / 朝下）：
-
-$$
-\theta_3 = \pm \arccos\left(\frac{r^2 - L_1^2 - L_2^2}{2L_1L_2}\right)
-$$
-
-**步骤 4**：求解 θ2
-
-$$
-\theta_2 = \arctan2(y_{j4}, x_{j4}) - \arctan2\left(L_2\sin\theta_3, L_1 + L_2\cos\theta_3\right)
-$$
-
-**步骤 5**：求解 θ4
-
-$$
-\theta_4 = \phi - \theta_2 - \theta_3
-$$
-
-### Python 实现
-
-```python
-def inverse_kinematics(x, y, z, phi_deg, elbow_up=False, L1=125, L2=125, x4=110, z4=80):
-    """逆运动学"""
-    phi = math.radians(phi_deg)
-    
-    # 步骤 1: 计算 J4 中心
-    x_j4 = x - x4 * math.cos(phi)
-    y_j4 = y - x4 * math.sin(phi)
-    z_j4 = z + z4
-    d1 = z_j4
-    
-    # 步骤 2: 平面距离
-    r2 = x_j4**2 + y_j4**2
-    r = math.sqrt(r2)
-

-    sin_theta3 = -math.sqrt(1 - cos_theta3**2) if elbow_up else math.sqrt(1 - cos_theta3**2)
-    theta3 = math.atan2(sin_theta3, cos_theta3)
-    
-    # 步骤 4: 求解 theta2
-    theta2 = math.atan2(y_j4, x_j4) - math.atan2(
-        L2 * sin_theta3,
-        L1 + L2 * cos_theta3
-    )
-    
-    # 步骤 5: 求解 theta4
-    theta4 = phi - theta2 - theta3
-    
-    # 角度归一化到 [-180, 180)
-    def normalize(angle):
-        a = (angle + math.pi) % (2 * math.pi) - math.pi
-        return a if a != -math.pi or angle <= 0 else math.pi
-    
-    return (
-        d1,
-        math.degrees(normalize(theta2)),
-        math.degrees(normalize(theta3)),
-        math.degrees(normalize(theta4))
-    )
-```
-
-## 零点偏移
-
-物理零点（机械对齐）与数学零点（直线构型）存在偏差：
-
-| 关节 | 零点偏移 |
-|------|----------|
-| J2 | +3° |
-| J3 | +7° |
-| J4 | +25° |
-
-### 转换关系
-
-**命令角度 ↔ 数学角度**：
-
-$$
-\theta_{\text{command}} = \theta_{\text{math}} + \text{offset}
-$$
-
-$$
-\theta_{\text{math}} = \theta_{\text{command}} - \text{offset}
-$$
-
-**使用**：
-- 正运动学：先减去偏移（命令 → 数学），再计算
-- 逆运动学：先计算（数学），再加上偏移（数学 → 命令）
-
-## 工作空间
-
-### 高度范围
-
-$$
-z \in [-290 - z_4, 0 - z_4] = [-370, -80] \text{ mm}
-$$
-
-### 水平范围
-
-$$
-r_{\min} = |L_1 - L_2| + x_4 = 0 + 110 = 110 \text{ mm}
-$$
-
-$$
-r_{\max} = L_1 + L_2 + x_4 = 125 + 125 + 110 = 360 \text{ mm}
-$$
-
-**可达圆环**：半径 110mm 到 360mm
-
-### 关节限位
-
-| 关节 | 最小值 | 最大值 | 单位 |
-|------|--------|--------|------|
-| height | -290 | 0 | mm |
-| J2 | -110 | 115 | ° |
-| J3 | -120 | 145 | ° |
-| J4 | -90 | 130 | ° |
-| J5 | -180 | 180 | ° |
-| J6 | -180 | 180 | ° |
-
-## 奇异点
-
-### 1. 肩部奇异点
-
-当 J4 中心在原点正上方：
-
-$$
-x_{j4} = y_{j4} = 0 \quad \Rightarrow \quad r = 0
-$$
-
-此时 θ2 无定义（可取任意值）。
-
-**避免**：保持 `r > 10mm`
-
-### 2. 肘部奇异点
-
-当机械臂完全伸直或完全折叠：
-
-$$
-\theta_3 = 0° \text{ 或 } \pm 180°
-$$
-
-此时运动控制不稳定。
-
-**避免**：保持 `|θ3| > 5°`
-
-## 运动插值
-
-关节空间线性插值，避免笛卡尔空间的复杂路径规划。
-
-### 算法
-
-给定起点 `q_start` 和终点 `q_end`，生成 N 个中间点：
-
-$$
-q_i = q_{\text{start}} + \frac{i}{N}(q_{\text{end}} - q_{\text{start}}), \quad i = 1, 2, \ldots, N
-$$
-
-### 参数
-
-- `duration`: 运动时长（秒）
-- `rate`: 插值频率（Hz）
-- `steps = ceil(duration × rate)`: 插值点数
-
-**示例**：`duration=2.0s`, `rate=20Hz` → `steps=40`
-
-### Python 实现
-
-```python
-def interpolate_joints(start, end, duration=2.0, rate=20.0):
-    """关节空间插值"""
-    steps = max(1, int(math.ceil(duration * rate)))
-    trajectory = []
-    
-    for i in range(1, steps + 1):
-        t = i / steps
-        state = {
-            key: int(round(start[key] + t * (end[key] - start[key])))
-            for key in start.keys()
-        }
-        trajectory.append(state)
-    
-    return trajectory
-```
-
-## 完整示例

-### 示例 1：前方抓取
-
-**目标**：抓取前方 250mm，右侧 50mm，高度 -150mm 的物体

-
-# 终端 2: 启动 vision_grasp 节点
-ros2 run udp_teleop vision_grasp \
-    --ros-args --params-file src/udp_teleop/config/vision_grasp.yaml
-```
-
-### 2. 启动方框检测节点
-
-#### 自动模式（检测到方框后自动抓取）
-
-```bash
-ros2 run udp_teleop box_detection_grasp \
-    --ros-args --params-file src/udp_teleop/config/box_detection_grasp.yaml \
-    -p auto_grasp:=true
-```
-
-#### 手动模式（仅检测，不自动抓取）

-   - 发布到 `/vision_grasp/grasp_target`
-   - vision_grasp 节点接收并执行抓取
-3. 等待 10 秒后完成（可自定义）
-4. 节点保持运行但不再检测
-
-### 手动模式 (auto_grasp=false)
-

-# 查看日志
-ros2 node list
-ros2 node info /box_detection_grasp
-```
-
-## 坐标系说明
-
-- **输入**：YOLO 检测框（图像像素坐标）
-- **输出**：相机坐标系 3D 坐标（单位：mm）
-  - X: 向右
-  - Y: 向下
-  - Z: 向前（深度）
-- **传递**：vision_grasp 节点自动转换到基坐标系
-
-## 深度估计原理
-
-使用透视投影原理：
-
-```
-Z = (实际尺寸 × 焦距) / 像素尺寸
-X = (u - cx) × Z / fx
-Y = (v - cy) × Z / fy
-```
-
-其中：
-- `box_size_m` = 方框实际边长（米）
-- `horizontal_fov_deg` = 相机水平视场角
-
-## 故障排除
-
-### 问题：无法连接到 ESP32 相机
-
-**解决**：
-1. 检查 ESP32 IP 地址：`ping 192.168.4.1`
-2. 浏览器访问：`http://192.168.4.1`
-3. 修改配置：`-p stream_url:=http://<IP>/stream`

-# CRAIC 定位系统文档
-
-激光 SLAM 建图 + AMCL 精准定位 + 示教记录点位。移植自 `lzu_robot` / `move_try`
-（同一赛事的参考实现），适配 CRAIC 麦轮底盘 + ESP32 + 机械臂平台。
-
----
-
-## 1. 概述
-
-- **目标**：在已知（预先测量）的竞赛场地上对底盘做绝对、无累积漂移的精准定位，并提供示教记录关键点位的工具。
-- **方案**：YDLiDAR → `rf2o` 激光里程计提供连续 `odom`；`slam_gmapping` 建一次场地地图；`nav2 AMCL` 用激光匹配已知地图做全局校正。
-- **运行环境**：ROS 2 Humble（conda/robostack `ros2_humble`）。机器人端工作区在 `~/Desktop/ros2`（下文命令默认在此目录、且已 `source install/setup.bash`）。
-
-> 设计上原打算用**轮式里程计**做运动来源，但实测 CRAIC 底盘板上电后只短时上报里程计（见 §8），
-> 故改用 `rf2o`（激光里程计）提供 `odom→base`，与 `lzu_robot`/`move_try` 一致。轮式里程计节点保留，
-> 待底盘板问题解决后可用 EKF 融合提精度。
-

-## 3. 软件清单
-
-### 自建包 `ros2/src/craic_localization`
-| 文件 | 作用 |
-|---|---|

-### 移植包
-- `ros2/src/ydlidar_ros2_driver` —— 来自 `move_try`，依赖系统 `ydlidar_sdk`（已装在 conda env）。
-- `ros2/src/rf2o_laser_odometry` —— 来自 `lzu_robot`，激光里程计（ICRA'16）。
-
-### 外部依赖（Nav2，已装入 conda env）
-`nav2_amcl`(amcl)、`nav2_map_server`(map_server, map_saver_cli)、`nav2_lifecycle_manager`(lifecycle_manager)、`slam_gmapping`/`openslam_gmapping`。
-
----
-
-## 4. 环境准备与编译
-
-一次性安装 Nav2 定位组件（若环境无）：
-```bash
-conda install -n ros2_humble -c robostack-staging -c conda-forge \
-    ros-humble-nav2-amcl ros-humble-nav2-map-server ros-humble-nav2-lifecycle-manager
-```
-
-编译（在工作区根目录）：
-```bash
-conda activate ros2_humble
-cd ~/Desktop/ros2
-colcon build --symlink-install --packages-select \
-    ydlidar_ros2_driver rf2o_laser_odometry craic_localization
-source install/setup.bash
-```
-
-> **开发机 ↔ 机器人同步**：代码在开发机维护，需同步到机器人 `~/Desktop/ros2` 后**重新 colcon build**。
-> 新增/改动包时务必确认源码已同步（尤其新包 `ydlidar_ros2_driver`、`rf2o_laser_odometry`）。
-
----
-
-## 5. 硬件接口
-
-| 设备 | 接口 | 说明 |
-|---|---|---|
-| 底盘 MCU | `/dev/ttylzucar` @115200 | 上报 32 字节里程计包；命令通过 ESP32 转发，非直连 |
-| 激光雷达 | `/dev/ttylzulaser` @230400 | YDLiDAR TminiPro，发 `/scan` 10Hz |
-| 底盘命令 | UDP `192.168.4.1:8888` → ESP32 → UART | `XYW:<x>:<y>:<w>:XZHY`（麦轮速度） |
-
-**底盘里程计协议**（移植自 lzu seriallzucar）：32 字节，帧尾 `'L''Z''U'`；`packet[0]`=校验和=`sum(packet[1:30])%256`；
-`packet[1:29]`=`<fffffff>`=`x,y,yaw,4轮位置`(x/y 单位 mm)；`packet[29]`=模式字节，`'D'`=有效。
-打开串口后下发 `UP0LZU` 使能上报（参数 `enable_cmd`）。
-
----
-
-## 6. 使用流程
-
-> 前置：每个终端都先 `cd ~/Desktop/ros2 && source install/setup.bash`。
-
-### 6.1 传感器自检（可选）
-```bash
-ros2 launch craic_localization bringup.launch.py
-```
-rviz 看 `/scan`、TF。用于核对激光朝向（调 `lidar_yaw` 等，见 §7）。
-
-### 6.2 建图
-```bash
-# 终端1：建图栈（激光 + rf2o + gmapping + rviz）
-ros2 launch craic_localization mapping.launch.py
-# 终端2：遥控慢速走遍场地（见 6.6）
-# 终端3：地图满意后存盘（gmapping 保持运行）
-mkdir -p src/craic_localization/maps
-ros2 run nav2_map_server map_saver_cli \
-    -f src/craic_localization/maps/craic \
-    --ros-args -p save_map_timeout:=10000.0
-```
-**走图要点**：慢、贴墙走遍每条边界、最后绕回起点；rviz Fixed Frame 设 `map`，墙应是单条清晰线、无重影。
-**起点即原点**：建图启动时机器人所在位置=map(0,0)、正前方=map +X。建议从固定起点开始。
-
-存盘得到 `craic.pgm` + `craic.yaml`。**确认 `craic.yaml` 含 `free_thresh`**（缺则 map_server 加载失败）：
-```bash
-tail -1 src/craic_localization/maps/craic.yaml   # 应为 free_thresh: 0.25
-# 若缺： printf '\nfree_thresh: 0.25\n' >> src/craic_localization/maps/craic.yaml
-```
-存盘后重编一次让默认地图安装：`colcon build --symlink-install --packages-select craic_localization`。
-> 地图四周大片灰色是 gmapping 预留画布（`xmin/xmax ±10` → 20m×20m），属正常，不影响 AMCL。
-
-### 6.3 定位（AMCL）
-```bash
-ros2 launch craic_localization localization.launch.py \
-    map:=$HOME/Desktop/ros2/src/craic_localization/maps/craic.yaml
-# 起点不在地图原点时给初值：加 init_x:= init_y:= init_yaw:=，或 rviz 工具栏 "2D Pose Estimate" 点
-```
-正常表现：rviz(Fixed Frame=`map`) 红色激光点贴合墙体，移动时始终咬住墙、位姿稳定不漂。
-
-### 6.4 定位精度测试
-```bash
-ros2 run tf2_ros tf2_echo map base_footprint    # 实时读 x/y/yaw
-ros2 topic echo /amcl_pose                       # 位姿 + 协方差
-```
-- **重复定位**：标记一物理点记位姿 → 开一圈回同点再记 → 差值 < 3cm 为佳。
-- **定长移动**：精确前进 1.00m，AMCL 报的位移误差应在几 cm 内。
-- (可选) rviz Add → PoseArray → `/particlecloud`，粒子收紧=收敛。
-
-### 6.5 示教记录点位
-```bash
-# 终端1：定位栈(6.3) 终端2：遥控(6.6) 终端3：示教
-ros2 run craic_localization teach_points --ros-args -p output_file:=$PWD/src/craic_localization/config/taught_points.yaml
-```
-交互命令：**回车/`r`** 记录当前预设点并前进；`p` 查看当前位姿；`name <X>` 记自定义点；
-`del <X>` 删除；`list` 列出；`skip`/`back` 跳过/回退；`save` 存盘；`q` 退出。
-预设顺序 `B_1..B_6, C_1, D_1, E_1, F_1`（每记一点自动存盘）。记 A 区用 `name A_1`…，或改 `points` 参数。
-输出（map 系，米/弧度）：
-```yaml
-points:
-  B_1: {x: 1.234, y: 0.456, yaw: 1.571}
-  ...
-```
-**在 rviz 看示教点**：`localization.launch.py` 已自动启动 `show_points`（青色箭头=位置+朝向，白字=点名，话题 `/taught_points`，rviz 内置 MarkerArray 显示）。
-想在示教**过程中实时**看到新点，给定位 launch 传 `points_file:=<你的 taught_points.yaml 绝对路径>`，或单独运行：
-```bash
-ros2 run craic_localization show_points --ros-args \
-    -p points_file:=$PWD/src/craic_localization/config/taught_points.yaml
-```
-
-### 6.6 自动导航到示教点
-读取 `taught_points.yaml`，用 AMCL 闭环把底盘开到指定点（麦轮 holonomic P 控制，经 UDP 发 XYW）。
-**首次务必先 dry_run 验证方向，再低速实测，手放 Ctrl+C（退出自动停车）。** 前置：定位栈(6.3) 在运行。
-```bash
-# ① 干跑：只打印命令不发，确认逻辑与方向符号
-ros2 run craic_localization navigate_to_point --ros-args \
-    -p points_file:=$PWD/src/craic_localization/config/taught_points.yaml \
-    -p dry_run:=true -p goal:=B_1
-# ② 交互选点（低速实测）
-ros2 run craic_localization navigate_to_point --ros-args \
-    -p points_file:=$PWD/src/craic_localization/config/taught_points.yaml \
-    -p max_linear:=40.0 -p max_angular:=20.0
-# ③ 一次性去某点 / 供上层任务程序用话题指定
-ros2 run craic_localization navigate_to_point --ros-args -p points_file:=... -p goal:=C_1
-ros2 topic pub -1 /goto std_msgs/String "{data: 'C_1'}"
-```
-交互命令：输入点名→导航；`s` 停车；`q` 退出。到达 `pos_tolerance`(5cm)/`yaw_tolerance`(~3°) 容差内停车。
-**若实车方向相反**：翻转 `sign_x`/`sign_y`/`sign_w`（默认 -1，按 keyboard_control 推导）。如左右反了 `-p sign_x:=1`。
-
-### 6.7 遥控
-```bash
-ros2 run udp_teleop keyboard_control --ros-args \
-    --params-file src/udp_teleop/config/params.yaml \
-    -p chassis_linear_speed:=40 -p chassis_angular_speed:=20    # 建图建议降速
-```
-按键：`W/S` 前后、`A/D` 左右平移、`Q/E` 左右转；`Ctrl+C` 退出。须 `ros2 run`、交互终端。
-

-
-## 7. 配置 / 关键参数
-
-**`lidar.launch.py`**：`lidar_x/y/z`、`lidar_yaw`(默认 -3.14159=-180°，使机体 X 轴对准底盘实际前进方向；若前后颠倒改 0.0)、
-`intensity`(true；基础 Tmini 无强度时改 false)、`sample_rate`(4)、`baudrate`(230400)、`base_frame`、`laser_frame`。
-
-**`localization.launch.py`**：`map`(地图 yaml)、`init_x/init_y/init_yaw`(初始位姿)、`use_rviz`。
-
-**`mapping.launch.py`**：`use_rviz`。范围 `xmin/xmax/ymin/ymax`(±10) 在 `config/gmapping.yaml`，可收小到 ±3 得更紧凑地图（需重新建图）。
-
-**`amcl.yaml`**：`odom_model_type: omni`(麦轮)、`base_frame_id: base_footprint`、`laser_max_range: 12.0`、`alpha1..5`(里程计噪声)。
-
-**`chassis_odometry`**（独立测试）：`port`、`enable_cmd`(UP0LZU)、`enable_cmd_period`(0=仅打开时发一次)、`require_mode_d`(true)。
-
-**`navigate_to_point`**：`points_file`、`goal`(一次性目标)、`max_linear`(60)/`max_angular`(30)、`kp_linear`(150)/`kp_angular`(40)、`pos_tolerance`(0.05)/`yaw_tolerance`(0.05)、`sign_x/sign_y/sign_w`(默认 -1，方向修正)、`goal_timeout`(30s)、`dry_run`、`udp_ip/udp_port`。

-## 8. 故障排查
-
-| 现象 | 原因 | 处理 |
-|---|---|---|
-| 激光狂刷 `Check Sum X != Y` | 有第二个进程在读 `/dev/ttylzulaser`，字节流被撕裂 | `pgrep -af ydlidar`；`pkill -f ydlidar_ros2_driver_node`；保证单实例。若仍报：试 `intensity:=false`（Tmini 无强度） |
-| gmapping `"base_link" ... does not exist` | gmapping 硬编码基准帧 `base_link`，而 TF 树只有 base_footprint | 已修：`lidar.launch.py` 发 base_footprint→base_link 恒等 TF |
-| gmapping `Message Filter ... queue is full`、地图/位置不动 | `odom→base` TF 冻结：轮式里程计板上电后只短时上报 | 已修：改用 `rf2o` 从 /scan 连续提供 odom→base（见 §1） |
-| map_server 加载地图失败 | `craic.yaml` 缺 `free_thresh` | 补 `free_thresh: 0.25`（见 6.2） |
-| rviz 地图上一串绿箭头 | Odometry 显示保留历史(Keep) | 已改默认 `Keep:1`；或 rviz 里取消勾选 Odometry（不影响地图） |
-| 轮式里程计只在上电后几帧有数据 | 底盘板上电后停止上报（固有行为，UP0LZU 未能维持） | 建图/定位已不依赖它；如需启用试 `enable_cmd_period:=1.0` 保活，或确认主机串口 TX 已接、或经 ESP32 通道使能 |
-| 时间戳显示 ~2000 年 | 机器人系统时钟未对时 | 单机不影响；多机协同前用 NTP/RTC 对时 |
-| 导航时往错误方向开 / 原地打转 | XYW 速度符号与实车不一致 | 翻转 `sign_x/sign_y/sign_w`(默认 -1)；先 `dry_run:=true` 核对，再低速实测 |
-| rviz 里机体朝向/前进方向与遥控差 90° | 激光外参 `lidar_yaw` 未校准 | 设 `lidar_yaw=-180°`(前后颠倒则 0.0)；改后 **yaw 变了需重新示教**，建议重建图 |
-| rviz 里示教点/地图整体乱飘跳动(机器人/激光却平滑) | Fixed Frame 设成了 `odom`，map 帧内容随 AMCL 每次校正跳变 | rviz Fixed Frame 改 `map`(已设为默认) |
-| 平移一段再返回，回位坐标误差大(静止时稳定) | 激光里程计 rf2o 运动跟踪偏差 + 麦轮物理漂移；**非地图大小问题** | 慢速驱动；根治用轮式里程计+EKF(见 §9)；先做物理标记/对比 rf2o 与 AMCL 定位区分原因 |
-| 激光点云形状对、但整体偏离墙线，AMCL 不往墙上贴 | `sigma_hit` 太小(0.05)→偏差超几 cm 就无梯度，AMCL 无法纠正 | 调大 `sigma_hit`(0.2)、`z_hit`(0.9)、`laser_max_range`(≥场地对角线)、`laser_likelihood_max_dist`(2.0)；并给准初始位姿 |
-
-通用排查：`ros2 run tf2_ros tf2_echo map base_footprint`、`ros2 topic hz /scan /odom /map`、
-`ros2 run tf2_tools view_frames`（看 TF 树连通）。

-## 9. 已知限制与后续
-
-- **激光外参标定**：`lidar_yaw` 已校准为 -180°，使机体 X 轴对准底盘实际前进方向（rviz 显示与遥控一致，导航默认符号 `sign_x/y/w=-1` 也随之正确）。平移 `lidar_x/y` 仍为 0 占位，需要更高位置精度可再标。
-  **改动 `lidar_yaw` 后**：机体朝向变了 —— 旧地图仍可定位（AMCL 自动补偿），但**示教点的 yaw 需重新记录**，建议重新建图让地图朝向也一致。
-- **轮式里程计**：底盘板“持续上报”问题待解；解决后可用 `robot_localization` EKF 融合 轮速 + rf2o 再喂 AMCL 提精度。
-- **地图坐标系**：`map(0,0)` = 建图起点。比赛复现时让机器人从同一物理起点开机，或用 “2D Pose Estimate” 给初值。

-# Repository Guidelines
-
-## Project Structure & Module Organization
-This repository is a ROS 2 workspace. Keep hand-written code under `src/`; treat top-level `build/`, `install/`, and `log/` as generated output. Core packages include `src/arm_control_msgs` for ROS messages/services, `src/udp_teleop` for arm and vision Python nodes, `src/craic_localization` for localization/navigation Python nodes, and C++ sensor packages such as `src/rf2o_laser_odometry` and `src/ydlidar_ros2_driver`. Launch files live in package `launch/`, runtime parameters in `config/` or `params/`, and RViz assets in `rviz/`.
-
-## Build, Test, and Development Commands
-Use the workspace script for normal builds:
-```bash
-./build.sh
-source install/setup.bash
-```
-`build.sh` sources ROS 2 Humble and runs `colcon build --symlink-install`.
-
-For targeted builds, prefer:
-```bash
-colcon build --packages-select craic_localization udp_teleop
-colcon build --packages-select arm_control_msgs --cmake-args -DPython_EXECUTABLE=$CONDA_PREFIX/bin/python
-```
-Run nodes with `ros2 run`, for example:
-```bash
-ros2 run udp_teleop arm_control --ros-args --params-file src/udp_teleop/config/arm_control.yaml
-```
-
-## Coding Style & Naming Conventions
-Python uses 4-space indentation, `snake_case` modules, and `snake_case` console script names such as `navigate_to_point`. ROS interfaces use `PascalCase` (`MovePose.srv`, `TCPPose.msg`). Launch files should end in `.launch.py`. Follow existing ROS 2 defaults: concise docstrings, parameter-driven behavior, and package-local config files. C++ packages build with C++14 and warnings enabled (`-Wall -Wextra -Wpedantic`); keep headers in `include/<package>/` and source in `src/`.
-
-## Testing Guidelines
-Run package tests before opening a PR:
-```bash
-colcon test --packages-select udp_teleop craic_localization
-colcon test-result --verbose
-```
-`udp_teleop/test/` currently contains ROS linter tests for `flake8` and `pep257`. Add new Python tests under `test/` with `test_*.py` names. For C++ packages, enable `BUILD_TESTING`-compatible tests when adding nontrivial logic.
-
-## Commit & Pull Request Guidelines
-Recent history follows Conventional Commits, often with scopes: `feat(craic_localization): ...`, `chore: ...`, `docs: ...`. Keep subjects imperative and under one line. PRs should describe affected packages, runtime impact, and exact validation commands. Include screenshots or RViz captures when changing visualization, launch behavior, or operator-facing workflows.
-
-## Generated Files & Configuration
-Do not commit edits inside generated `build/`, `install/`, or `log/` directories. Update source files instead, then rebuild. Keep machine-specific IPs, ports, and calibration values in package YAML files under `config/` or `params/`, and document any hardware assumptions in the PR.

-# ROS 2 机械臂控制系统
+# ros2 — ROS 2 工作空间
 
-CRAIC 项目的 ROS 2 机械臂控制和视觉抓取系统。
+## 环境搭建
 
-## 📦 包含组件
+支持以下三种安装方式，任选其一。
 
-### 1. arm_control_msgs
+### 方式一：Conda (robostack，跨平台)
-消息和服务定义包。
 
-**消息类型**：
+适用于 Linux / macOS / Windows，无需 root 权限。
-- `JointState` - 关节状态
-- `TCPPose` - TCP 位姿
-
-**服务类型**：
-- `MoveJoints` - 关节空间运动
-- `MovePose` - 笛卡尔空间运动
-- `GetPose` - 查询当前位姿
-- `SetGripper` - 夹爪控制
-
-### 2. arm_control 节点
-独立的机械臂控制节点（不依赖 tools/udp_control.py）。
-
-**功能**：
-- 关节空间和笛卡尔空间运动控制
-- 完整的逆运动学和正运动学
-- **自动 z4 适配**：根据目标 z 坐标自动选择夹爪状态
-  - `z > -55mm`: UP（J5=-100，z4=-100），工作范围 z ∈ [-190, 110]mm
-  - `z ≤ -55mm`: DOWN（J5=81，z4=55），工作范围 z ∈ [-345, -55]mm
-- UDP 通信（与 ESP32）
-- 状态发布（10Hz）
-
-### 3. vision_grasp 节点
-自动化视觉抓取节点。
-
-**功能**：
-- 相机坐标到基坐标系的自动转换
-- **自动处理相机旋转**：根据 J5 状态自动调整图像坐标转换
-- 抓取流程：释放 → 移动 → 抓取 → 回收
-- 释放流程：移动 → 释放 → 回收
-
-**相机旋转说明**：
-- J5 < 0°（闭合/UP）：相机正向，`(xc, yc, zc) = (x_img, -y_img, z)`
-- J5 > 0°（张开/DOWN）：相机旋转 180°，`(xc, yc, zc) = (-x_img, y_img, z)`
-
-## 🚀 快速开始
-
-### 编译
 
 ```bash
+# 安装 Miniconda
+wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
+bash Miniconda3-latest-Linux-x86_64.sh
+
+# 创建 ROS 2 Humble 环境
+conda create -n ros2_humble -c robostack-staging -c conda-forge ros-humble-desktop
+conda activate ros2_humble
+
+# 安装构建工具
+conda install -c robostack-staging -c conda-forge \
+    colcon-common-extensions \
+    ros-humble-ament-cmake \
+    pip
+
+# Python 依赖
+pip install pynput
+```
+
+### 方式二：apt 原生安装 (Ubuntu 22.04)
+
+官方推荐的 Ubuntu 安装方式，系统级集成。
+
+```bash
+# 添加 ROS 2 源
+sudo apt update && sudo apt install curl gnupg lsb-release
+sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key \
+    -o /usr/share/keyrings/ros-archive-keyring.gpg
+echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(lsb_release -cs) main" \
+    | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null
+
+# 安装 ROS 2 Humble
+sudo apt update
+sudo apt install ros-humble-desktop python3-colcon-common-extensions
+
+# Python 依赖
+pip install pynput
+
+# 环境配置（或写入 ~/.bashrc）
+source /opt/ros/humble/setup.bash
+```
+
+### 方式三：Docker
+
+推荐用于 CI/CD 或快速体验，无需污染宿主机环境。
+
+```bash
+# 拉取镜像
+docker pull osrf/ros:humble-desktop
+
+# 启动容器（挂载工作空间）
+docker run -it --rm \
+    -v $(pwd)/ros2:/ws \
+    osrf/ros:humble-desktop \
+    bash
+
+# 容器内安装依赖
+apt update && apt install -y python3-colcon-common-extensions python3-pip
+pip install pynput
+```
+
+## 构建
+
+```bash
+# 每次新终端都需要先加载 ROS 2 环境
+source /opt/ros/humble/setup.zsh
+
 cd ros2

 ```
 
-### 运行
+> `--symlink-install`：修改 Python 源文件后无需重新构建，直接生效。
 
-**机械臂控制**：
+## 运行
-```bash
-ros2 run udp_teleop arm_control \
-    --ros-args --params-file src/udp_teleop/config/arm_control.yaml
-```
-
-**视觉抓取**：
-```bash
-# 终端 1: 启动 arm_control
-ros2 run udp_teleop arm_control \
-    --ros-args --params-file src/udp_teleop/config/arm_control.yaml
-
-# 终端 2: 启动 vision_grasp
-ros2 run udp_teleop vision_grasp \
-    --ros-args --params-file src/udp_teleop/config/vision_grasp.yaml
-```
-
-## 📚 使用示例
-
-### 1. 控制机械臂
 
 ```bash
-# 查询位姿
+ros2 run udp_teleop keyboard_control \
-ros2 service call /arm_control/get_pose arm_control_msgs/srv/GetPose
+    --ros-args --params-file src/udp_teleop/config/params.yaml
-
-# 关节运动
-ros2 service call /arm_control/move_joints arm_control_msgs/srv/MoveJoints \
-    "{height: -100, j2: 10, j3: 20, j4: 30, j5: 81, j6: 30, duration: 2.0}"
-
-# 笛卡尔运动
-ros2 service call /arm_control/move_pose arm_control_msgs/srv/MovePose \
-    "{x: 200.0, y: 100.0, z: -100.0, phi: 45.0, duration: 2.0}"
 ```
 
-### 2. 视觉抓取
+也可以通过命令行覆盖参数：
 
 ```bash
-# 发布抓取目标（相机坐标）
+ros2 run udp_teleop keyboard_control \
-ros2 topic pub --once /vision_grasp/grasp_target geometry_msgs/Point \
+    --ros-args -p udp_ip:=192.168.1.100 -p udp_port:=9999
-    "{x: 10.0, y: 5.0, z: 250.0}"
-
-# 发布释放目标（基坐标）
-ros2 topic pub --once /vision_grasp/release_target geometry_msgs/Point \
-    "{x: 100.0, y: 150.0, z: -100.0}"
 ```
 
-### 3. Python 集成
+## 包文档
 
-```python
+详见 [src/udp_teleop/README.md](src/udp_teleop/README.md)，包含按键映射、UDP 协议、参数配置等。

-
-## ⚙️ 配置
-
-### arm_control 参数
-
-编辑 `src/udp_teleop/config/arm_control.yaml`：
-
-```yaml
-arm_control:
-  ros__parameters:
-    udp_ip: '192.168.4.1'      # ESP32 IP
-    udp_port: 8888
-    
-    # 几何参数 (mm)
-    l1: 125.0

-    height_max: 0
-    j2_min: -110
-    j2_max: 115
-    
-    # 运动参数
-    default_duration: 1.0      # 默认运动时长 (秒)
-    default_rate: 20.0         # 插值频率 (Hz)
-```
-
-### vision_grasp 参数
-
-编辑 `src/udp_teleop/config/vision_grasp.yaml`：

-**服务**：
-- `/arm_control/move_joints` - 关节运动
-- `/arm_control/move_pose` - 位姿运动
-- `/arm_control/get_pose` - 查询位姿
-- `/arm_control/set_gripper` - 夹爪控制
-
-**话题**（发布）：

-
-### vision_grasp
-
-**话题**（订阅）：
-- `/vision_grasp/grasp_target` - 抓取目标（相机坐标）
-- `/vision_grasp/release_target` - 释放目标（基坐标）
-
-## 🐛 故障排查
-
-### 编译失败
-
-**问题**：找不到 Python 开发文件
-
-**解决**：设置环境变量
-```bash
-export PYTHON_EXECUTABLE=$CONDA_PREFIX/bin/python
-export PYTHON_INCLUDE_DIR=$CONDA_PREFIX/include/python3.12
-export PYTHON_LIBRARY=$CONDA_PREFIX/lib/libpython3.12.so
-```
-
-### 服务调用超时
-
-**问题**：vision_grasp 节点服务调用超时
-
-**原因**：在回调中使用 `time.sleep()` 阻塞了执行器
-
-**解决**：已使用多线程执行器和独立线程处理
-
-### 移动失败
-
-**检查**：
-1. ESP32 是否在线：`ping 192.168.4.1`
-2. UDP 是否可达：`echo 'XYW:0:0:0:XZHY' | nc -u 192.168.4.1 8888`
-3. 目标是否在工作空间内
-4. 关节限位是否合理

-发布 nav_msgs/Odometry (/odom) 与 TF (odom -> base_footprint)。
-

-
-- 目标点：读取 teach_points 生成的 taught_points.yaml（map 系 x,y,yaw）。
-- 反馈：TF map->base_footprint（= AMCL 实时定位），需 localization.launch.py 在运行。
-- 控制：holonomic P 控制器，把 map 系位姿误差投影到机体系，生成 (前进, 侧移, 转向)
-        速度，按 udp_teleop 的 XYW 约定经 UDP→ESP32 下发，到达容差内停车。
-
-速度符号默认按 udp_teleop/keyboard_control 推导：
-  前进 W→chassis_y 取负, 左移 A→chassis_x 取负, 左转(CCW) Q→chassis_w 取负
-  => sign_x = sign_y = sign_w = -1。若实车方向相反，翻转对应 sign 参数即可。
-
-用法：

-  ros2 run craic_localization navigate_to_point --ros-args \
-      -p points_file:=$PWD/src/craic_localization/config/taught_points.yaml

-  # 干跑（只打印命令不发，安全验证逻辑/符号）
-  ros2 run craic_localization navigate_to_point --ros-args -p points_file:=... -p dry_run:=true

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    {one line to give the program's name and a brief idea of what it does.}
-    Copyright (C) {year}  {name of author}
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    {project}  Copyright (C) {year}  {fullname}
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

-
-Estimation of 2D odometry based on planar laser scans. rf2o is a fast and precise method to estimate the planar motion of a lidar from consecutive range scans. Useful for mobile robots with inaccurate wheel odometry.
-
-For every scanned point we formulate the range flow constraint equation in terms of the sensor velocity, and minimize a robust function of the resulting geometric constraints to obtain the motion estimate. Conversely to traditional approaches, this method does not search for correspondences but performs dense scan alignment based on the scan gradients, in the fashion of dense 3D visual odometry.
-
-The very low computational cost (0.9 milliseconds on a single CPU core) together whit its high precision, makes RF2O a suitable method for those robotic applications that require planar odometry.
-
-For a full description of the algorithm, please refer to: **Planar Odometry from a Radial Laser Scanner. A Range Flow-based Approach. ICRA 2016** Available at: http://mapir.uma.es/papersrepo/2016/2016_Jaimez_ICRA_RF2O.pdf

-*  2D laser range measurements.
-*  This module is developed for mobile robots with innacurate or inexistent built-in odometry.
-*  It allows the estimation of a precise odometry with low computational cost.

+```
+
+## 环境搭建
+
+### 1. 安装 Conda
+
+使用 Miniconda 或 Anaconda。推荐 Miniconda：
+
+```bash
+# 下载并安装 Miniconda
+wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
+bash Miniconda3-latest-Linux-x86_64.sh
+```
+
+### 2. 创建 ROS 2 Humble 环境
+
+使用 robostack 频道安装 ROS 2 Humble Desktop 完整版：
+
+```bash
+conda create -n ros2_humble -c robostack-staging -c conda-forge ros-humble-desktop
+```
+
+### 3. 安装构建工具
+
+```bash
+conda activate ros2_humble
+conda install -c robostack-staging -c conda-forge \
+    colcon-common-extensions \
+    ros-humble-ament-cmake \
+    python3-pip
+```
+
+### 4. 安装 Python 依赖
+
+```bash
+pip install pynput
+```
+
+### 5. 激活环境
+
+每次使用前：
+
+```bash
+conda activate ros2_humble
+source /path/to/ros2/install/setup.bash   # 首次构建后执行
+```
+
+## 构建
+
+```bash
+cd ros2
+colcon build --symlink-install --packages-select udp_teleop
+source install/setup.bash
+```
+
+> `--symlink-install`：修改 Python 源文件后无需重新构建，直接生效。
+
+## 运行
+
+### 使用参数文件（推荐）
+
+```bash
+ros2 run udp_teleop keyboard_control \
+    --ros-args --params-file src/udp_teleop/config/params.yaml
+```
+
+### 命令行覆盖参数
+
+```bash
+ros2 run udp_teleop keyboard_control \
+    --ros-args -p udp_ip:=192.168.1.100 -p udp_port:=9999
+```
+
+## 按键映射
+
+### 底盘控制
+
+| 按键 | 功能 |
+|------|------|
+| `W` / `S` | 前进 / 后退 |
+| `A` / `D` | 左移 / 右移 |
+| `Q` / `E` | 左转 / 右转 |
+
+### 机械臂控制
+
+| 按键 | 功能 |
+|------|------|
+| `↑` / `↓` | 升降高度（↑ 升高，↓ 降低） |
+| `2` ~ `6` | 选择关节 J2 ~ J6 |
+| `←` / `→` | 减小 / 增大当前关节角度 |
+
+> 底盘和机械臂可以**同时操控**。机械臂指令仅在按下机械臂相关按键后发送。
+
+### 其他
+
+| 按键 | 功能 |
+|------|------|
+| `Ctrl+C` | 退出并发送底盘停止指令 |
+
+## UDP 协议
+
+### 底盘指令
+
+```
+XYW:<X速度>:<Y速度>:<W角速度>:XZHY\n
+```
+
+### 机械臂指令
+
+```
+JXB:<高度>:<J2>:<J3>:<J4>:<J5>:<J6>:0:0:EZHY\n
+```
+
+- 6 个电机：电机 1 控制高度，电机 2~6 对应关节 J2~J6
+- 末尾补零至 8 个值
+
+## 参数配置
+
+| 参数 | 默认值 | 说明 |
+|------|--------|------|
+| `udp_ip` | `127.0.0.1` | UDP 目标 IP 地址 |
+| `udp_port` | `8888` | UDP 目标端口 |
+| `chassis_linear_speed` | `100` | 底盘线速度 |
+| `chassis_angular_speed` | `45` | 底盘角速度 |
+| `arm_height_step` | `5` | 高度每步变化量 |
+| `arm_joint_step` | `5` | 关节角度每步变化量 |
+| `update_rate` | `0.05` | 控制循环周期（秒） |
+| `stdin_hold_time` | `0.04` | 按键持续时间（秒），修复箭头键时序问题 |
+| `debug_keys` | `false` | 是否在状态行显示当前按键 |
+| `keyboard_backend` | `auto` | 键盘后端：`auto` / `stdin` / `pynput` / `win_poll` |
+
+## 键盘后端
+
+| 后端 | 说明 |
+|------|------|
+| `auto` | 自动选择：Linux/macOS 用 `stdin`，Windows 用 `win_poll` |
+| `stdin` | 基于终端原始输入，无需额外依赖，**需要交互终端** |
+| `pynput` | 基于 pynput 库，跨平台，需要 `pip install pynput` |
+| `win_poll` | Windows 专用，通过 Win32 API 轮询按键状态 |
+
+> `ros2 launch` 启动的子进程**没有交互终端**，使用 `stdin` 后端会报错。必须通过 `ros2 run` 在终端直接运行。

-# YDLIDAR ROS2 Driver
-
-ydlidar_ros2_driver is a new ros package, which is designed to gradually become the standard driver package for ydlidar devices in the ros2 environment.
-
-## How to [install ROS2](https://index.ros.org/doc/ros2/Installation)
-[ubuntu](https://index.ros.org/doc/ros2/Installation/Dashing/Linux-Install-Debians/)
-
-[windows](https://index.ros.org/doc/ros2/Installation/Dashing/Windows-Install-Binary/)
-
-## How to Create a ROS2 workspace
-[Create a workspace](https://index.ros.org/doc/ros2/Tutorials/Colcon-Tutorial/#create-a-workspace)
-
-
-## Compile & Install YDLidar SDK
-
-ydlidar_ros2_driver depends on YDLidar-SDK library. If you have never installed YDLidar-SDK library or it is out of date, you must first install YDLidar-SDK library. If you have installed the latest version of YDLidar-SDK, skip this step and go to the next step.
-
-1. Download or clone the [YDLIDAR/YDLidar-SDK](https://github.com/YDLIDAR/YDLidar-SDK) repository on GitHub.
-2. Compile and install the YDLidar-SDK under the ***build*** directory following `README.md` of YDLIDAR/YDLidar-SDK.
-
-## Clone ydlidar_ros2_driver
-
-1. Clone ydlidar_ros2_driver package for github : 
-
-   `git clone https://github.com/YDLIDAR/ydlidar_ros2_driver.git ydlidar_ros2_ws/src/ydlidar_ros2_driver`
-
-2. Build ydlidar_ros2_driver package :
-
-   ```
-   cd ydlidar_ros2_ws
-   colcon build --symlink-install
-   ```
-   Note: install colcon [see](https://index.ros.org/doc/ros2/Tutorials/Colcon-Tutorial/#install-colcon)
-
-   ![CMAKE Finished](images/finished.png  "CMAKE Finished")
-
-   <font color=Red size=4>>Note: If the following error occurs, Please install  [YDLIDAR/YDLidar-SDK](https://github.com/YDLIDAR/YDLidar-SDK) first.</font>
-
-   ![CMAKE ERROR](images/cmake_error.png  "CMAKE ERROR")
-
-3. Package environment setup :
-
-   `source ./install/setup.bash`
-
-    Note: Add permanent workspace environment variables.
-    It's convenientif the ROS2 environment variables are automatically added to your bash session every time a new shell is launched:
-    ```
-    $echo "source ~/ydlidar_ros2_ws/install/setup.bash" >> ~/.bashrc
-    $source ~/.bashrc
-    ```
-4. Confirmation
-    To confirm that your package path has been set, printenv the `grep -i ROS` variable.
-    ```
-    $ printenv | grep -i ROS
-    ```
-    You should see something similar to:
-        `OLDPWD=/home/tony/ydlidar_ros2_ws/install`
-
-5. Create serial port Alias [optional] 
-    ```
-	$chmod 0777 src/ydlidar_ros2_driver/startup/*
-	$sudo sh src/ydlidar_ros2_driver/startup/initenv.sh
-    ```
-    Note: After completing the previous operation, replug the LiDAR again.
-	
-## Configure LiDAR [paramters](params/ydlidar.yaml)

-## 完整工作流示例
-
-### 1. 测试机械臂连接
 
 ```bash
-# 1. 启动回显服务器
+# 示例：ROS 2 键盘遥控 → 本地回显
-python udp_server.py
+ros2 run udp_teleop keyboard_control \
-
+    --ros-args -p udp_ip:=127.0.0.1 -p udp_port:=8888
-# 2. 测试 UDP（新终端）
-echo 'JXB:0:0:0:0:81:30:0:0:EZHY' | nc -u 127.0.0.1 8888
-
-# 3. 验证服务器收到消息
-```
-
-### 2. 机械臂运动测试
-
-```bash
-# 测试关节运动
-python udp_control.py joints --height -50 --j2 10 --j3 20 --j4 30 --duration 2.0
-
-# 测试笛卡尔运动
-python udp_control.py pose --x 200 --y 100 --z -100 --phi 45 --duration 2.0
-
-# 测试抓取
-python udp_control.py pose --x 200 --y 100 --z -150 --phi 45 --grip --duration 1.0
-```
-
-### 3. 视觉抓取流程
-
-```bash
-# 步骤 1: 采集图像
-python camera_capture.py --ip 192.168.4.1 --output target.jpg
-
-# 步骤 2: 检测物体（假设得到像素坐标和宽度）
-# u=320, v=240, pixel_width=50
-# 使用相似三角形计算深度：depth = (real_width * focal_length) / pixel_width
-# 转换到相机坐标：x_cam, y_cam, z_cam
-
-# 步骤 3: 获取当前 TCP 位姿（从 ROS 或状态文件）
-# tcp_x=200, tcp_y=0, tcp_z=-120, phi=0
-
-# 步骤 4: 坐标变换
-python camera_to_base.py \
-    --camera 10 -5 250 \
-    --tcp 200 0 -120 --phi 0
-
-# 步骤 5: 移动到目标
-python udp_control.py pose --x 323.5 --y 229.6 --z -108.6 --phi 0 --duration 3.0
-
-# 步骤 6: 抓取
-python udp_control.py pose --x 323.5 --y 229.6 --z -158.6 --phi 0 --grip --duration 1.0
-
-# 步骤 7: 回收
-python udp_control.py pose --x 200 --y 0 --z -158.6 --phi 0 --duration 2.0
-```
-
-## 状态缓存
-
-`udp_control.py` 会将最后发送的关节状态保存到：
-```
-~/.ros/udp_control_state.json
-```
-
-这允许连续运动时从上一个位置平滑插值，而不是从原点跳跃。
-
-**禁用缓存**：
-```bash
-python udp_control.py pose --x 200 --y 0 --z -100 --phi 0 --no-state-cache
-```
-
-## UDP 协议
-
-所有工具通过 UDP 端口 8888 与 ESP32 通信。
-
-**机械臂命令格式**：
-```
-JXB:<height>:<J2>:<J3>:<J4>:<J5>:<J6>:0:0:EZHY\n
-```
-
-- 所有角度已包含零点偏移
-- 高度单位：mm
-- 角度单位：度
-
-**底盘命令格式**：
-```
-XYW:<X>:<Y>:<W>:XZHY\n
-```
-
-## 依赖
-
-```bash
-pip install numpy
-```
-
-可选（用于相机采集）：
-```bash
-pip install opencv-python requests
-```
-
-## 故障排查
-
-### 1. 无法连接 ESP32
-
-**检查**：
-```bash
-# 测试网络连接
-ping 192.168.4.1
-
-# 测试 UDP 端口
-echo 'test' | nc -u 192.168.4.1 8888
-```
-
-### 2. 逆运动学失败
-
-**错误**：`目标超出工作空间`
-
-**原因**：目标位置超出机械臂可达范围
-
-**解决**：
-- 检查目标是否在圆环内（半径 110-360mm）
-- 检查高度是否在范围内（-370 到 -80mm）
-
-### 3. 运动不平滑
-
-**解决**：
-- 增加 `--duration`（运动时间）
-- 增加 `--rate`（插值频率）
-- 确保状态缓存已启用
-
-### 4. 关节角度超限
-
-**错误**：`J2=-150 超出范围 [-110, 115]`
-
-**解决**：
-- 检查目标位姿是否合理
-- 尝试 `--elbow-up` 切换肘部解
-

-- **ROS 节点**：`ros2/README.md` - ROS 2 集成
-- **视觉标定**：`docs/vision_calibration_horizontal.md` - 相机标定
-
-## 开发
-
-这些工具是独立的 Python 脚本，不依赖 ROS。可以直接在任何 Python 3 环境中运行。
-
-**测试**：
-```bash
-# 测试逆运动学
-python udp_control.py pose --x 200 --y 0 --z -100 --phi 0 --dry-run --show-fk
-
-# 测试坐标变换
-python camera_to_base.py --camera 0 0 300 --tcp 200 0 -120 --phi 0

-Mechanical structure used here:
-1. J2/J3/J4 rotate around the Z axis in the XY plane.
-2. The gripper TCP has a fixed offset relative to the J4 frame: (x4, 0, z4).
-3. ``phi`` is the TCP yaw in the XY plane and is always ``J2 + J3 + J4``.
-4. All linear pose and geometry values are millimeters.
-
-Supports two control modes:
-1. Direct joint command mode.
-2. Cartesian TCP pose mode using the inverse kinematics from ``docs/craic.md``.
