Apptronik Apollo
Apptronik Apollo is a humanoid with 32 joints, made by Apptronik. This model comes from MuJoCo Menagerie by Google DeepMind, under the Apache-2.0 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 apptronik_apollo 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.
| Setting | Value | Where it comes from |
|---|---|---|
| Control rate | 50 Hz | Playground apollo/joystick.py ctrl_dt=0.02 |
| Action | offset from the default pose | Playground apollo/joystick.py: motor_targets = default_ctrl + action * action_scale |
| Action scale | 0.5 | Playground apollo/joystick.py action_scale=0.5 |
| What a policy senses | joint positions, joint velocities, base angular velocity, gravity direction | Apollo's joint encoders and IMU |
| Command | forward, sideways and turning speed | Playground's joystick command (vx, vy, yaw) |
| Everything else | read from the model file | joint order, the stand keyframe, ranges, per-group kp, armature and force limits from the MJCF's own <position> actuators, and its 5 ms timestep. |
