| # 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. |
