# gc_bringup
GC 机器人启动包 — 阿克曼底盘 + 激光雷达 + SLAM 建图 + AMCL 导航
## 📁 目录结构
```
gc_bringup/
├── launch/
│ ├── slam_mapping.launch.py # SLAM 在线建图
│ ├── navigation.launch.py # AMCL 定位 + Nav2 导航
│ └── navigation_slam.launch.py # slam_toolbox 定位 + Nav2 导航
├── config/
│ ├── nav2_params.yaml # Nav2 参数(阿克曼配置)
│ ├── mapper_params_online_async.yaml # slam_toolbox 建图参数
│ └── mapper_params_localization.yaml # slam_toolbox 定位参数
├── maps/ # 地图文件存放
├── rviz/ # RViz2 配置文件
├── CMakeLists.txt
└── package.xml
```
## 🚀 使用方式
### 1. 编译
```bash
cd ~/test_ws
colcon build --packages-select gc_bringup
source install/setup.bash
```
### 2. SLAM 建图
启动 Gazebo + 机器人 + slam_toolbox 在线异步建图:
```bash
ros2 launch gc_bringup slam_mapping.launch.py
```
在 RViz 中使用 "2D Nav Goal" 工具驱动机器人探索环境建图。
保存地图:
```bash
ros2 run nav2_map_server map_saver_cli -f ~/test_ws/src/gc_bringup/maps/my_map
```
### 3. AMCL 导航(推荐)
使用建好的地图进行 AMCL 定位 + Nav2 导航:
```bash
ros2 launch gc_bringup navigation.launch.py
```
操作步骤:
1. 在 RViz 中使用 "2D Pose Estimate" 设置初始位姿
2. 使用 "2D Nav Goal" 设置导航目标
### 4. slam_toolbox 定位导航
使用 slam_toolbox 定位模式(需要 .posegraph 文件):
```bash
ros2 launch gc_bringup navigation_slam.launch.py
```
## 🔧 启动参数
| 参数 | 默认值 | 说明 |
|------|--------|------|
| `use_sim_time` | `true` | 使用仿真时间 |
| `use_gazebo` | `true` | 启动 Gazebo |
| `use_rviz` | `true` | 启动 RViz2 |
| `world` | `origincar_description/world/gc_world.world` | Gazebo 世界文件 |
| `map` | `gc_bringup/maps/my_map.yaml` | 导航用地图 |
## 🤖 机器人说明
- **底盘类型**: 阿克曼转向 (Ackermann)
- **传感器**: 360° 激光雷达 (LiDAR)、IMU
- **控制器**: MPPI (Ackermann 运动模型)
- **规划器**: Smac Hybrid (Reeds-Shepp支持倒车)
- **定位**: AMCL (自适应蒙特卡洛定位) 或 slam_toolbox 定位模式
