# so100_test

Converted Apache TsFile version of [`diaawoo/so100_test`](https://huggingface.co/datasets/diaawoo/so100_test), a LeRobot SO100 tutorial robot dataset.

## Source Dataset

- Original dataset: [`diaawoo/so100_test`](https://huggingface.co/datasets/diaawoo/so100_test)
- Source tags: `LeRobot`, `so100`, `tutorial`
- Source split: `train`
- Source storage: one Parquet shard at `data/train-00000-of-00001.parquet`
- Source scale: 2 episodes, 1,184 frames, 30 fps
- Modalities: Time-series. The downloaded source snapshot does not include a `videos/` directory.

## TsFile Layout

- Data file: `data/so100_test.tsfile`
- Table name: `so100_test`
- Rows: 1,184
- Time precision: milliseconds
- TAG columns: `episode_index`
- FIELD columns: `frame_index`, `sample_index`, `next_done`, `observation_state_0` through `observation_state_5`, and `action_0` through `action_5`

The converted table uses the original LeRobot `episode_index` column as the TsFile TAG column. The source parquet does not contain `task_index`, so no synthetic `task_index`, `episode_id`, or `task_id` column is created.

## Conversion Notes

- Converted with the generic `lerobot` converter in the `huggingface_to_tsfile` pipeline.
- `Time = round(timestamp * 1000)` in milliseconds and restarts per episode.
- The source `timestamp` column is not retained as a separate FIELD because it is redundant with `Time / 1000`.
- The source `index` column is renamed to `sample_index`.
- Vector columns are flattened while preserving the full source column name with `.` replaced by `_`: `observation.state[6]` becomes `observation_state_0..observation_state_5`, and `action[6]` becomes `action_0..action_5`.
- Numeric arrays are stored as single-precision FLOAT fields.
- Source metadata is mirrored under `meta_data/`, with `meta_data/info.json` updated to describe the converted TsFile schema and conversion mapping.
