| # aloha_static_candy
|
|
|
| This dataset converts the numeric time-series from
|
| [`lerobot/aloha_static_candy`](https://huggingface.co/datasets/lerobot/aloha_static_candy)
|
| to Apache TsFile format.
|
|
|
| ## Dataset Description
|
|
|
| The source dataset was created using
|
| [LeRobot](https://github.com/huggingface/lerobot). It is an ALOHA robot
|
| dataset published by the LeRobot team.
|
|
|
| - Source dataset: [`lerobot/aloha_static_candy`](https://huggingface.co/datasets/lerobot/aloha_static_candy)
|
| - Project: [ALOHA](https://tonyzhaozh.github.io/aloha/)
|
| - Paper: <https://arxiv.org/abs/2304.13705>

|
| ## Converted Data
|
|
|
| - 50 episodes, 35,000 frames, 50 fps
|
| - One TsFile: `aloha_static_candy.tsfile`
|
| - Table name: `aloha_static_candy`
|
| - TAG columns: `episode_index`, `task_index`
|
| - Time: `round(timestamp * 1000)` milliseconds
|
| - Source `timestamp` is used to synthesize `Time` and is not retained as a
|
| separate field
|
| - `observation.state[14]` is flattened to
|
| `observation_state_0..observation_state_13`
|
| - `action[14]` is flattened to `action_0..action_13`
|
| - Aside from the redundant source `timestamp` column noted above, no source
|
| time-series columns or rows are dropped
|
|
|
| ## Videos
|
|
|
| Video files are not included in this converted TsFile repository. The original
|
| camera streams remain in the source HuggingFace dataset:
|
|
|
| <https://huggingface.co/datasets/lerobot/aloha_static_candy/tree/main/videos>
|
|
|
| Use `episode_index`, `frame_index`, and `Time` to align TsFile rows with the
|
| original videos.
