| # 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> |
| - License: MIT |
|
|
| ## 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. |
