LeRobot v3 keeps many episodes in one file. Download the data file and keep the rows whose episode_index is 0. Each video file holds several episodes back to back: cut it to episode_seconds. Or load it with LeRobot: LeRobotDataset('behavior-1k/2026-challenge-demos', episodes=[0]). The data file is 82 MB and holds many episodes; data_via_index gives only this one's rows.

Columns of the data file:

- `action`: float32, shape 23 (action)
- `next.reward`: float32, shape 1 (reward)
- `next.terminated`: bool, shape 1 (done)
- `next.truncated`: bool, shape 1 (done)
- `observation.state`: float32, shape 61
- `observation.robot2cam_pose.left_realsense_link_camera_0`: float32, shape 7
- `observation.robot2cam_pose.right_realsense_link_camera_0`: float32, shape 7
- `observation.robot2cam_pose.zed_link_camera_0`: float32, shape 7
- `timestamp`: float32, shape 1
