We are thrilled to announce that the Unitree Go2/G1 robot has now been integrated with the Nvidia Isaac Sim (Orbit), marking a major step forward in robotics research and development. The combination of these two cutting-edge technologies opens up a world of possibilities for creating and testing algorithms in a variety of simulated environments.
Get ready to take your research to the next level with this powerful new resource at your fingertips!

You need to install:
- Ubuntu 22.04
- Nvidia Isaac Sim 2023.1.1
- Nvidia Orbit 0.3.0
- Ros2 Humble
Full instruction:
After installation of Nvidia Isaac Sim 2023.1.1 and Ros2 Humble:
1. Clone this specific IsaacLab repo version: https://github.com/isaac-sim/IsaacLab/releases/tag/v0.3.1
2. Execute in ubuntu terminal:
export ISAACSIM_PATH="${HOME}/.local/share/ov/pkg/isaac-sim-2023.1.1"
export ISAACSIM_PYTHON_EXE="${ISAACSIM_PATH}/python.sh"
and also put it inside .bashrc file
3. Inside the root folder of Orbit repo (https://github.com/isaac-sim/IsaacLab/releases/tag/v0.3.1) execute ln -s ${ISAACSIM_PATH} _isaac_sim
4. Execute ./orbit.sh --conda
5. Execute conda activate orbit
6. Execute sudo apt install cmake build-essential
7. Execute ./orbit.sh --install
8. Execute ./orbit.sh --extra rsl_rl
9. Verify the installation using "python source/standalone/tutorials/00_sim/create_empty.py" You should be inside conda env.
10. You need to check that you have "Isaac Sim Python 2023.1.1 - New Stage*" on the top of the window.
11. Clone this repo with git clone https://github.com/abizovnuralem/go2_omniverse/ --recurse-submodules -j8 --depth=1
12. Copy the config file Unitree_L1.json (located in go2_omniverse/Isaac_sim/Unitree/Unitree_L1.json) for the Unitree L1 LiDAR to the folder IsaacLab-0.3.1/source/data/sensors/lidar/Unitree_L1.json (if the path doesnt exists, create it)
13. Copy all material files in the isaac-sim-2023.1.1/data/material_files folder to IsaacLab_v0.3.1/source/data/material_files (if the path doesnt exists, create it)
14. Execute ./run_sim.sh (without activated conda orbit env)
Some suggestions:
- You need to check nvidia-smi, it should work, before installing Isaac Sim
- You need to install Miniconda and execute: conda config --set auto_activate_base false
- Install Omniverse launcher and then install Isaac Sim.
- You need to install ROS2 on your system and configure it:
https://docs.omniverse.nvidia.com/isaacsim/latest/installation/install_ros.html#isaac-sim-app-install-ros
The current project was tested on Ubuntu 22.04, IsaacSim 2023.1.1 with Orbit 0.3.0 and Nvidia Driver Version: 545. To start the project with Unitree GO2, execute:
./run_sim.sh
To start the project with Unitree G1, execute:
./run_sim_g1.sh
You can control the dog using "WASD" keyboard commands
You can use https://github.com/abizovnuralem/go2_ros2_sdk as a basement for your ROS2 setup.
To use predifined custom envs, you need to download files from https://drive.google.com/drive/folders/1vVGuO1KIX1K6mD6mBHDZGm9nk2vaRyj3?usp=sharing and place them to /envs folder. Then you can execute it modifying run_sim.sh script with --custom_env=office and --terrain flat commands. If you are doing it first time, it will take 2-3 minutes to configure the env. Please, wait.
To contribute or modify the project, refer to these resources for implementing additional features or improving the existing codebase. PRs are welcome!
To enable VR support on linux will take some time, but it works! I have tested it on:
- Ubuntu 22.04
- Nvidia drivers are 545.29.06
- SteamVR 2.4.4 (IMPORTANT! It should be 2.4.4) and you need to go to Compatibility tab (Inside Steam app) and "Force the use of a specific Steam Play compatibility tool" and switch to "Steam-Play-None", additional info you can find in ALVR github issues tab.
- ALVR streamer 20.8.1 + Oculus Quest 2 (client ALVR you can install via SideQuest app) (How to install it: https://github.com/alvr-org/ALVR)
- Execute IsaacSim, Go to Window -> Extensions, find STEAMVR INPUT/OUTPUT then enable it and enable AutoLoad. Reopen IsaacSim. Use OpenXR mode.
- Enjoy Omniverse in VR mode!
