# bridge_single_view

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

## Dataset Description

`bridge_single_view` is a full-data repack of Bridge v2 into LeRobot v3 with a
single canonical visual stream:

- all source episodes and tasks are preserved
- only the always-present primary camera is kept
- `observation.images.image_0` is renamed to `observation.images.image`
- `camera_present` is removed because it is degenerate in the single-view output
