 # CM_DOG

-A simple ROS2 program for a legged robot. Developed for Robocon2025.
+A simple ros2 program for legged robot . Robocon2025

-## 硬件配置
-
- **关节电机**: Unitree GO-8010-6 (12个)
- **IMU传感器**: 轮趣科技 N100陀螺仪
- **通信接口**: USB转思路RS485
-
-## 软件依赖
-
- Ros2 humble
-
-## 使用说明
-
-1. 克隆仓库：
-
-2. 构建项目：
+有点不太会用ros2 controller 所以直接做的控制。

+## 1. Steps to transfer urdf to Mujoco model
+
+* Install [Mujoco](https://github.com/google-deepmind/mujoco)
+* Transfer the mesh files to mujoco supported format, like stl.
+* Adjust the urdf tile to match the mesh file. Transfer the mesh file from .dae to .stl may change the scale size of the
+  mesh file.
+* use `xacro` to generate the urdf file.
+  ```
+  xacro robot.xacro > ../urdf/robot.urdf
+  ```
+* use mujoco to convert the urdf file to mujoco model.
+  ```
+  compile robot.urdf robot.xml
+  ```
+
+## 2. Dependencies for Gazebo Simulation
+
+Gazebo Simulation only tested on ROS2 Jazzy. It add support for ROS2 Humble because the package name is different.
+
+* Gazebo Harmonic
+  ```bash
+  sudo apt-get install ros-jazzy-ros-gz
+  ```
+* Ros2-Control for Gazebo
+  ```bash
+  sudo apt-get install ros-jazzy-gz-ros2-control
+  ``` 
+* Legged PD Controller
+    ```bash
+    cd ~/ros2_ws
+    colcon build --packages-up-to leg_pd_controller
+    ```
+
+## 2. Dependencies for Gazebo Classic Simulation
+
+Gazebo Classic (Gazebo11) Simulation only tested on ROS2 Humble.
+
+* Gazebo Classic
+  ```bash
+  sudo apt-get install ros-humble-gazebo-ros
+  ```
+* Ros2-Control for Gazebo
+  ```bash
+  sudo apt-get install ros-humble-gazebo-ros2-control
+  ``` 
+* Legged PD Controller
+    ```bash
+    cd ~/ros2_ws
+    colcon build --packages-up-to leg_pd_controller
