Overview

This package contains a simplified robot description (MJCF) of the YAM robot developed by I2 RT Robotics. It is derived from the publicly available URDF description.

MJCF derivation steps

1. Started from yam.urdf (commit SHA d4efb66d81bd8bde42909880b16591d4af82e8c0).
2. Added the following to the URDF <robot> tag <mujoco><compiler balanceinertia="true" discardvisual="false" fusestatic="false" strippath="false"/></mujoco>.
3. Loaded the URDF into MuJoCo and saved a corresponding MJCF.
4. Added home keyframe.
5. Added tracking light.
6. Add frictionloss (not identified).
7. Added armature based on reflected inertia values provided by the manufacturer.
8. Switched to implicitfast and used position actuators with kp/kv semantics.
