| # Boxing a First Aid Kit (TsFile) |
|
|
| Converted from [`woohyunwoo/boxing_a_first_aid_kit`](https://huggingface.co/datasets/woohyunwoo/boxing_a_first_aid_kit) at pinned revision [`392bd7088c2561c0d6fc7a11b7e652933c2ec56d`](https://huggingface.co/datasets/woohyunwoo/boxing_a_first_aid_kit/tree/392bd7088c2561c0d6fc7a11b7e652933c2ec56d). **Modalities: Time-series.** |
|
|
| ## Dataset description |
|
|
| This LeRobot v2.1 dataset contains dual-arm SO100 demonstrations for the source task labeled `boxing_a_first_aid_kit`. |
|
|
| The pinned task table contains one task: `boxing_a_first_aid_kit`. |
|
|
| - **Source repository owner/publisher:** woohyunwoo |
| - **License:** apache-2.0 (declared by the source card). |
| - **Paper/homepage/citation:** no completed paper, homepage, or citation is documented in the pinned source card unless linked above. |
|
|
| > **Source metadata note:** The source README embeds an older 22-episode/25,235-frame snapshot. Counts here use the pinned `meta/info.json`, 50 source episode Parquets, staged rows, and TsFile metadata. |
|
|
| ## Dataset Scale |
|
|
| | Split | Episodes | Tasks | Source trajectory Parquets | TsFile rows | Sampling rate | TsFile files/shards | |
| |---|---:|---:|---:|---:|---:|---:| |
| | `train` | 50 | 1 | 50 | 48,777 | 30 Hz | 1 | |
|
|
| The staged Parquet has 48,777 rows and 29 columns including `Time`; TsFile chunk metadata independently reports the same 48,777 rows. |
|
|
| ## TsFile schema |
|
|
| | Column | Role | TsFile type | Observed/source range | |
| |---|---|---|---| |
| | `Time` | TIME | INT64 | 0–45,567 ms; restarts per episode | |
| | `episode_index` | TAG | STRING | source integer 0–49 | |
| | `task_index` | TAG | STRING | source integer 0–0 | |
| | `frame_index` | FIELD | INT64 | 0–1,367 within an episode | |
| | `sample_index` | FIELD | INT64 | 0–48,776 globally | |
|
|
| Exact remaining FIELD names/ranges and imported types: |
|
|
| - `action_0`–`action_11` (FLOAT): left and right shoulder pan/lift, elbow flex, wrist flex/roll, and gripper actions |
| - `observation_state_0`–`observation_state_11` (FLOAT): the corresponding 12 dual-arm state coordinates |
|
|
| ## Conversion |
|
|
| - All source episodes in the train split are merged into `data/boxing_a_first_aid_kit_train.tsfile`; `episode_index` and `task_index` are TAG dimensions. |
| - `Time = round(timestamp * 1000)` in milliseconds. The source `timestamp` column is omitted because it is redundant with `Time / 1000` seconds. |
| - `frame_index` is retained. Source `index` is retained as `sample_index`. |
| - Every vector is fully flattened: the complete source name is kept, `.` becomes `_`, and element indices are appended. Float vectors are imported as single-precision FLOAT fields. |
| - Other scalar source columns shown above are retained; no trajectory rows are intentionally dropped. |
| - Source metadata is mirrored for publication, with copied `meta/info.json` rewritten to describe the converted data path and conversion semantics. |
|
|
| ## Video policy |
|
|
| The pinned metadata declares 150 source videos across overview, left, and right cameras. MP4 files were not downloaded or uploaded; they remain in [the pinned source `videos/` tree](https://huggingface.co/datasets/woohyunwoo/boxing_a_first_aid_kit/tree/392bd7088c2561c0d6fc7a11b7e652933c2ec56d/videos). |
|
|
| ## Minimal read example |
|
|
| ```python |
| from tsfile import TsFileReader |
| |
| reader = TsFileReader("data/boxing_a_first_aid_kit_train.tsfile") |
| print(reader.get_all_table_schemas().keys()) |
| reader.close() |
| ``` |
