saaduddinM/rbo_oxe_base_droid_lerobot

This dataset is a pruned, one-camera subset of the original IPEC-COMMUNITY/droid_lerobot:

• Removed episodes with empty task text (e.g., "tasks": [""]).
• Grouped by task string and kept ≤ 4 episodes per unique task.
• For each kept episode, kept exactly one camera stream, chosen at random from
  {observation.images.exterior_image_1_left, observation.images.exterior_image_2_left, observation.images.wrist_image_left}, and unified it under the single key observation.images.image.
• Reindexed episodes to [0..N-1], rebuilt task_index from task text, and updated meta/ (info.json, episodes.jsonl, tasks.jsonl, stats.json).
• Kept Parquet files strictly numeric/time-series; pixels live in MP4s (as in the source dataset).

Note: To compute image statistics in meta/stats.json, we combine the original per-camera stats weighted by how many frames from each camera survived.

Quick stats (this release)

• Episodes: 39,530
• Frames: 11,543,142
• Tasks (unique): 31,305
• Videos: 39,530 (one per episode)
• Frames kept by source camera (for transparency):
  wrist_image_left: 3,856,202 · exterior_image_1_left: 3,854,740 · exterior_image_2_left: 3,832,200
