MuscleMimic Demo Dataset

Demo retargeted motion data for the MyoFullBody musculoskeletal model, generated using General Motion Retargeting (GMR). This dataset provides lightweight example files for testing MuscleMimic data loading, visualization, and evaluation workflows.

This dataset is derived from AMASS and is provided only for permitted non-commercial research uses.

Dataset Groups

Group	Motions	Description
MyoBimanualArm/gmr	7	Demo upper-body and bimanual motions for MyoBimanualArm
MyoFullBody/gmr	3	Demo full-body locomotion motions for MyoFullBody

Fill in the Motions counts after checking the files on Hugging Face.

Usage

from huggingface_hub import snapshot_download

dataset_path = snapshot_download(
    repo_id="amathislab/demo_dataset",
    repo_type="dataset",
)
print(dataset_path)

If using this dataset through MuscleMimic, point the relevant dataset/cache configuration to the downloaded files.

File Format

Each .npz file contains retargeted motion data with arrays: qpos, qvel, xpos, xquat, cvel, subtree_com, site_xpos, site_xmat, plus metadata (joint_names, body_names, site_names, frequency, split_points).
