Description

Teleop support for Unitree G1 with Inspire 5-finger hand, take PickPlace task as an example.

Type of change

  • New feature (non-breaking change which adds functionality)

Changes:

-Preparation of the humanoid robot asset: Unitree G1 (29 DOF) with Inspire 5-finger hand
-Configuration of the robot’s articulation
-Retargeting setup for the humanoid robot
-Creation of the manipulation task environment: pickplace_unitree_g1_inspire_hand_env_cfg.py
-Updated the how-to tutorial of cloudxr_teleoperation.rst.

Below is a diagram showing the robot asset and the workflow in teleop.

Test Steps

  1. Run the teleop task with:
    python scripts/tools/record_demos.py
    --task Isaac-PickPlace-G1-InspireFTP-Abs-v0
    --teleop_device handtracking
    --enable_pinocchio

  2. Replay the collected demos with:
    python scripts/tools/replay_demos.py
    --task Isaac-PickPlace-G1-InspireFTP-Abs-v0
    --enable_pinocchio
    --dataset_file datasets/dataset.hdf5

The USD file and corresponding URDF files(left hand and right hand) for dex retargeting configuration have been uploaded to temp position Collected_g1_29dof
I am confirming with @renato Gasoto regarding the correct destination and access permissions.

This G1_29dof asset is different from the existing G1 on S3 in the following ways:

  1. Number of DOFs: The current G1 on S3 has 23 DOFs, while the new version has 29 DOFs.
  2. Composited asset: The new asset integrates the 5-finger Inspire hand, and both the robot/hand asset and merging code are provided below.
    """
    Configuration for the Unitree G1 Humanoid robot with Inspire 5fingers hand.
    The Unitree G1 URDF can be found here: https://github.com/unitreerobotics/unitree_ros/tree/master/robots/g1_description/g1_29dof_with_hand_rev_1_0.urdf
    The Inspire hand URDF is available at: https://github.com/unitreerobotics/xr_teleoperate/tree/main/assets/inspire_hand
    The merging code for the hand and robot can be found here: https://github.com/unitreerobotics/unitree_ros/blob/master/robots/g1_description/merge_g1_29dof_and_inspire_hand.ipynb,
    Necessary modifications should be made to ensure the correct parent–child relationship.

Note: There is a related PR3150, which includes modifications to some common files. Once PR3150 is merged, I can rebase my code to avoid any duplication. Thanks.

high level comment:
robot - worflow specific definition maybe more appropriate in isaaclab_tasks rather than in core. Things in core should be mostly just pure interface how robot - worflow specific definition should use them

Yes, that makes more sense. Since we are following the GR1 convention and the code freeze is approaching, we can refactor this part in the next release?
