aloha_static_battery

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

Source Dataset

Conversion notes:

  • LeRobot v3.0 robot dataset: 49 episodes, 29,400 frames, 50 fps, 1 task.
  • All episodes are stored in a single TsFile under data/aloha_static_battery.tsfile with source columns episode_index and task_index as TAG columns; query one episode with WHERE episode_index=N.
  • Vector columns are flattened to single-precision FLOAT, preserving the source column name: . is replaced with _ and the element index is appended.
  • Time is synthesized as round(timestamp * 1000) milliseconds, restarting per episode. Dropped column: source timestamp (seconds), because it equals Time / 1000. frame_index is kept and index is renamed to sample_index.
  • Source camera videos are not included in this repository. They remain in the original dataset under videos/.
  • meta/ is mirrored from the source. meta/info.json describes the converted TsFile schema.

Conversion Notes

  • Conversion mode: script
  • Time precision: ms
  • TsFile data files: ['data/aloha_static_battery.tsfile']
  • Converter: scripts/converters/lerobot.py

Usage 

# Read the .tsfile files with the Apache TsFile Java/Python SDK.
