| # roarm_m3_test
|
|
|
| This dataset is converted from
|
| [`dudulrx0601/roarm_m3_test`](https://huggingface.co/datasets/dudulrx0601/roarm_m3_test)
|
| to Apache TsFile format.
|
|
|
| Modalities: Time-series. The original dataset also contains laptop and phone
|
| camera video streams, which remain in the source Hugging Face dataset and are
|
| not included in this converted repository.
|
|
|
| ## Source Dataset
|
|
|
| - Original dataset: [`dudulrx0601/roarm_m3_test`](https://huggingface.co/datasets/dudulrx0601/roarm_m3_test)
|
| - Format: LeRobot v2.0
|
| - Robot type: `unknown`
|
| - License: `apache-2.0`
|
| - Scale: 50 episodes, 4,739 frames, 1 task (`pick`), 30 fps
|
| - Original data path: `data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet`
|
| - Original video path: `videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4`
|
|
|
| ## Converted Files
|
|
|
| - TsFile data: `data/roarm_m3_test.tsfile`
|
| - Mirrored metadata: `meta/`
|
| - Rows in TsFile: 4,739
|
| - Time precision: milliseconds
|
|
|
| ## Schema
|
|
|
| `Time` is synthesized as `round(timestamp * 1000)` and restarts per episode.
|
|
|
| TAG columns:
|
|
|
| - `episode_index`
|
| - `task_index`
|
|
|
| FIELD columns:
|
|
|
| - `frame_index`
|
| - `sample_index` renamed from source `index`
|
| - `next_done` renamed from source `next.done`
|
| - `observation_state_0` through `observation_state_5`, flattened from `observation.state[6]`
|
| - `action_0` through `action_5`, flattened from `action[6]`
|
|
|
| Flattened vector values are stored as single-precision FLOAT fields.
|
|
|
| ## Conversion Notes
|
|
|
| - The source `timestamp` column is not retained as a separate field because it
|
| is redundant with `Time / 1000` seconds.
|
| - Source video streams `observation.images.laptop` and
|
| `observation.images.phone` are not uploaded here. Use the original dataset
|
| videos:
|
| https://huggingface.co/datasets/dudulrx0601/roarm_m3_test/tree/main/videos
|
| - `meta/info.json` is mirrored from the source and updated to describe the
|
| converted TsFile schema, original video path, row count, TAG columns,
|
| flattened features, renamed fields, and video policy.
|
| - Aside from the redundant `timestamp` field and omitted video streams, no rows
|
| or numeric time-series fields are intentionally dropped.
|
|
|
| ## Read Example
|
|
|
| ```python
|
| # Read data/roarm_m3_test.tsfile with the Apache TsFile Java/Python SDK.
|
| # Query one episode with a predicate such as:
|
| # WHERE episode_index = 0
|
| ```
