| # dagger_final_1_21 (TsFile) | |
| Apache TsFile version of the LeRobot dataset | |
| [`lerobot-data-collection/dagger_final_1_21`](https://huggingface.co/datasets/lerobot-data-collection/dagger_final_1_21). | |
| ## Overview | |
| Bimanual openarms-follower demonstrations (LeRobot v3.0). | |
| - **Robot:** openarms_follower (bimanual) | |
| - **Episodes:** 1 | |
| - **Frames:** 841 | |
| - **Sampling rate:** 30 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..15`, `action_0..15`) as single-precision FLOAT. | |
| The robot's the left_wrist / right_wrist / base camera 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. | |
| ## Usage | |
| Read the `.tsfile` files with the Apache TsFile Java or Python SDK. | |
