This dataset was created using LeRobot.

This is a reconstructed dataset. Original recording durations are preserved with held images/poses across missing intervals. Wrist-camera timing is approximate in all episodes; 41.46 seconds have unsupported poses, marked by is_lost. It is not verified one-to-one synchronized training data. See recovery details and masks.

Dataset Structure

Two video observations (observation.images.left_cam0, observation.images.left_cam1), eight action values (position, rotation vector, and two gripper angles), and is_lost, using the same feature schema as ParallaxData/sliding_door_clean.

Recovery Metadata

Additional validity flags are stored separately in meta/recovery_masks.parquet so they do not add charts to the standard visualizer. Join them by index or by episode_index and frame_index; standard training code does not load them automatically. Per-frame provenance and validation results are also retained.

Citation

No associated paper.

Dataset Copy

Copied from willlyb/snack_transfer. All 10 episodes and their recovery limitations are retained. The _clean name does not imply additional filtering or repaired tracking.
