This dataset was created using [LeRobot](https://github.com/huggingface/lerobot).

## Dataset Description

This dataset is a lerobot conversion of the `aloha_pen_uncap_diverse` subset of [BiPlay](https://huggingface.co/datasets/oier-mees/BiPlay/tree/main/aloha_pen_uncap_diverse_raw).

BiPlay contains 9.7 hours of bimanual data collected with an aloha robot at the RAIL lab @ UC Berkeley, USA. It contains 7023 clips, 2000 language annotations and 326 unique scenes.
