## Dataset Overview
- **Desktop Fine-Grained Part Sorting**
- `Part_Sorting`: 3000 episodes
- **Carton Sealing and Packing**
- `Packing_Box`: 1367 episodes
- **Foam Inlaying**
- `Foam_Inlaying`: 539 episodes
- **Covert Sorting**
- `Conveyor_Sorting`: 1064 episodes
## Data Format
Each dataset contains multiple episodes stored in Parquet format:
**LeRobot v3.0** (e.g., `part_sorting_long_756_episode`, `Packing_Box`, `Foam_Inlaying`, `Conveyor_Sorting`):
```
{dataset_name}/data/chunk-000/file-XXX.parquet
```
- Data filename: `file-{file_index}.parquet`
- Dataset ID format: `{action}_{description}` (e.g., `part_sorting_long_756_episode`)
Field definitions can be found in the main project at `lerobot/common/policies/utils.py` under observation/action definitions.
