Language Table (LeRobot) — Task-Pruned, Reindexed Subset

This release is a task-pruned subset of the original **IPEC-COMMUNITY/language_table_lerobot**. We subsampled by task text and rebuilt the package so it remains internally consistent (indices, splits, stats, paths).

  • —Robot: xArm
  • —Modality: RGB video + states + actions
  • —FPS / Resolution: 10 FPS, 360×640, AV1
  • —License: apache-2.0 (inherits from source)

What’s different in this subset

  • —Kept ~0.85% of unique tasks (uniform random over task strings).
  • —Capped at ≤ 8 trajectories per kept task.
  • —Unified camera key to observation.images.image (source often used observation.images.rgb).
  • —Reindexed episodes to [0..N-1] and rewrote episode_index in each Parquet; rebuilt `task_index` from task text.
  • —Rebuilt `meta/`:
  • —info.json (totals, splits, chunk counts),
  • —tasks.jsonl (compact mapping of task text → task_index),
  • —episodes.jsonl (new indices/paths/lengths with source_episode_index provenance),
  • —stats.json (numeric columns recomputed from kept data; image stats under the unified key).
Pixels live in MP4s under videos/.../{video_key}/...; Parquet holds numeric/time-series only.
