• Sampling rate: 15 fps
• Tasks: 1

Schema (TsFile structure)

• Time (INT64, milliseconds) — round(timestamp * 1000), restarting per episode.
• episode_index / task_index (TAG) — the device dimension. Query a single episode with WHERE episode_index=N.
• FIELD — frame_index, sample_index, and the flattened state/action vectors (observation_state_0..3, action_0..3) as single-precision FLOAT.

next.reward and next.done are kept.

The robot's camera video streams are time-series-irrelevant and not uploaded to this repository; get them from the original dataset (its videos/ directory). The source meta/ is mirrored here.
