Unitree Go2 Description

This repository contains the urdf model of go2.

go2

Tested environment:

  • Ubuntu 24.04
    • ROS2 Jazzy
  • Ubuntu 22.04
    • ROS2 Humble

Build

cd ~/ros2_ws
colcon build --packages-up-to go2_description --symlink-install

Visualize the robot

To visualize and check the configuration of the robot in rviz, simply launch:

source ~/ros2_ws/install/setup.bash
ros2 launch go2_description visualize.launch.py

Launch ROS2 Control

Mujoco Simulator

When used for isaac gym or other similiar engine

Collision parameters in urdf can be amended to better train the robot:

Open "go2_description.urdf" in "./go2_description/urdf", and amend the box size="0.213 0.0245 0.034" in links of "FL_thigh", "FR_thigh", "RL_thigh", "RR_thigh".

For example, change previous values to box size="0.11 0.0245 0.034" means the length of the thigh is shortened from 0.213 to 0.11, which can avoid unnecessary collision between the thigh link and the calf link.

The collision model before and after the above amendment are shown as "Normal_collision_model.png" and " Amended_collision_model.png" respectively.
