MuJoCoPickAndPlace v1 TsFile
Apache TsFile representation of johnsutor/MuJoCoPickAndPlace-v1, a LeRobot v3.0 MuJoCo robotics dataset.
Source
- Author and publisher: John Sutor (
johnsutor) - License: Apache-2.0
- Task: Pick up the red cube and place it on the blue circle.
- Robot type: SO-101
- Split:
train(0:10) - Sampling rate: 30 fps
- Episodes: 10; frame rows: 4,725; tasks: 1; source Parquet shards: 1
- Source frame layout:
data/chunk-{chunk_index:03d}/file-{file_index:03d}.parquet
The source card does not provide a paper or completed BibTeX citation.
TsFile layout
The numeric rows are stored in data/johnsutor_mujoco_pick_and_place_v1.tsfile as table johnsutor_mujoco_pick_and_place_v1. Source metadata JSON is retained under meta/; the task and episode metadata are represented as JSONL, and no source Parquet file is placed there.
Time = round(timestamp * 1000) is an INT64 millisecond timeline that restarts at zero for every episode. The source timestamp is omitted because it equals Time / 1000 seconds. index is renamed to sample_index, and frame_index is preserved.
| Role | Columns |
|---|---|
| TIME | Time (INT64, milliseconds) |
| TAG/device | episode_index, task_index |
| FIELD | frame_index, sample_index (INT64) |
| FIELD | action[6] -> action_0 ... action_5 (FLOAT) |
| FIELD | observation.state[6] -> observation_state_0 ... observation_state_5 (FLOAT) |
| FIELD | observation.environment_state[36] -> observation_environment_state_0 ... observation_environment_state_35 (FLOAT) |
| FIELD | reward, success, done, and six reward_components_* values (FLOAT) |
No numeric row, action dimension, state dimension, environment-state dimension, reward value, or frame index is dropped.
Videos
Videos remain in the original Hugging Face repository and are not included here:
videos/observation.images.overhead/chunk-000/file-000.mp4(23,757,203 bytes)videos/observation.images.wrist/chunk-000/file-000.mp4(17,189,090 bytes)
The source layout is videos/{video_key}/chunk-{chunk_index:03d}/file-{file_index:03d}.mp4. Numeric rows align with both camera streams through episode_index, frame_index, and the offsets recorded in meta/episodes.jsonl.
