Pico motion-transfer data for WB-WAM intermediate training. LeRobot v3.0, 20 Hz, RGB 360 × 270. The release contains 13,396 episodes, 1,579,028 frames, 73 tasks, and 302 independent recordings (21.931 hours).

Each <task>/record_XXXX/ is an independent LeRobot dataset. Recordings of the same task remain separate:

text

<task>/record_XXXX/
  data/chunk-000/file-000.parquet
  videos/<camera>/chunk-000/file-000.mp4

  meta/stats.json
  meta/tasks.parquet
  meta/episodes/chunk-000/file-000.parquet

The Dataset Viewer plays the MP4 files. The corresponding Parquet state/action rows and metadata are available under each recording in Files and versions.

Field	Meaning
`observation.state`	float32[110]: body state[9], G1 joint angles[29], G1 joint velocities[29], left/right Wuji hands[40], root[3]
`action`	float32[136]: next SONIC token[64], left/right Wuji hands[40], G1 joints[29], root[3]
`state_mask_110`, `action_mask_136`	bool[110/136]; `True` means invalid. Both hands have supervision.
`timestamp`, `frame_index`, `episode_index`, `index`, `task_index`	Time and row/episode/task indices.
`next.done`	Last frame of an episode.

The action contains absolute next-frame joint targets (+50 ms), not joint increments. Root[3] denotes roll, pitch, and body-frame z angular velocity, not XYZ position. Pico hand data may include reconstructed or held values. See each record's meta/info.json for exact slices and camera keys.

Download the unpacked files directly:

bash

hf download WB-WAM/Pico --repo-type dataset --local-dir ./data/pico_archive

To load one recording with LeRobot 0.4.4, use its local record directory as root:

python

from lerobot.datasets.lerobot_dataset import LeRobotDataset

dataset = LeRobotDataset("WB-WAM/Pico", root="./data/pico_archive/<task>/record_XXXX")
sample = dataset[0]
