Unitree Go1

Unitree Go1 is a quadruped, made by Unitree Robotics. This model comes from MuJoCo Menagerie by Google DeepMind, under the BSD-3-Clause licence. The licence text is in LICENSE.

Not made by Lucen Robotics. Listed as a reference model for simulation.

The source's own README is kept unchanged as SOURCE_README.md.

How it was set up

The files come from unitree_go1 in MuJoCo Menagerie, at commit 822c2d8. The robot card was drafted from the model by lucen robot init, as in Add your robot.

The model file does not state the values below. Each one comes from the source beside it.

SettingValueWhere it comes from
Control rate50 HzPlayground go1/joystick.py ctrl_dt=0.02
Actionoffset from the default posePlayground go1/joystick.py: motor_targets = default_pose + action * action_scale
Action scale0.5Playground go1/joystick.py action_scale=0.5
What a policy sensesjoint positions, joint velocities, base angular velocity, gravity directionthe Go1's joint encoders and IMU
Commandforward, sideways and turning speedPlayground's joystick command (vx, vy, yaw)
Everything elseread from the model filejoint order, the home keyframe, and kp 100 with per-joint force limits from the MJCF's own <position> actuators (Playground's task retunes its own copy to Kp 35 / Kd 0.5).

The configs cited above, at the commits read:

  • Playground: MuJoCo Playground, commit 4057c14. Each robot's task file, under locomotion or manipulation, in its default_config().

No file from the source was changed. This README, the robot card and the robot's pictures are new.
