## Overview
|
|
|
|
This package contains a simplified robot description (MJCF) of the [G1 Humanoid
|
|
Robot](https://www.unitree.com/g1/) developed by [Unitree
|
|
Robotics](https://www.unitree.com/). It is derived from the [publicly available
|
|
MJCF
|
|
description](https://github.com/unitreerobotics/unitree_ros/blob/master/robots/g1_description/g1_29dof_rev_1_0.xml). Specifically, this model has the fully actuated waist but not the full hands.

## MJCF derivation steps
|
|
|
|
1. Copied the MJCF description from [g1_description](https://github.com/unitreerobotics/unitree_ros/blob/master/robots/g1_description/g1_29dof_rev_1_0.xml).
|
|
2. Manually edited the MJCF to extract common properties into the `<default>` section.
|
|
3. Added stand keyframe.
|
|
4. Added joint position actuators (needs tuning).
|
|
5. Applied similar edits to `g1_with_hands.xml`.
