taco_play

Converted from the Hugging Face dataset lerobot/taco_play to Apache TsFile format.

Modalities: Time-series.

Source Dataset

The source TACO Play dataset was created using LeRobot. The original dataset page links to the Kaggle homepage at https://www.kaggle.com/datasets/oiermees/taco-robot and the papers https://arxiv.org/abs/2209.08959 and https://arxiv.org/abs/2210.01911.

  • License: cc-by-4.0
  • Source scale: 3,603 episodes, 237,798 frames, 406 tasks, 15 fps
  • Source robot type: unknown
  • Source video streams: observation.images.rgb_static and observation.images.rgb_gripper

Converted Files

  • data/taco_play.tsfile: one TsFile table containing all train episodes
  • meta/info.json: source metadata rewritten to describe the TsFile artifact
  • meta/stats.json, meta/tasks.parquet, meta/episodes/chunk-000/file-000.parquet: source metadata mirrored for reference

Videos are not included in this repository. They remain in the original Hugging Face dataset under https://huggingface.co/datasets/lerobot/taco_play/tree/main/videos.

TsFile Schema

  • Time: millisecond timestamp, synthesized as round(timestamp * 1000).
  • TAG columns: episode_index, task_index.
  • FIELD columns: frame_index, sample_index, next_reward, next_done, observation_state_0..observation_state_6, and action_0..action_6.

Vector columns preserve the source column name with . replaced by _, then append the element index. observation.state[7] becomes observation_state_0..observation_state_6; action[7] becomes action_0..action_6. Vector values are stored as single-precision FLOAT.

The source timestamp column is dropped because it is redundant with Time. The source index column is renamed to sample_index. Source video feature columns are omitted from the TsFile table and remain available in the original dataset.

Read Example

Use the Apache TsFile Java or Python SDK to read:

data/taco_play.tsfile

The table name is taco_play. Query a single episode by filtering the TAG:

WHERE episode_index = 0
