Dataset Overview

• Desktop Fine-Grained Part Sorting

  • part_sorting_long_756_episode: long sequence, 756 episodes
  • part_sorting_short_1000_episode: short sequence, 1000 episodes

• Carton Sealing and Packing

  • box_closing_001: 50 episodes

Data Format

Each dataset contains multiple episodes stored in Parquet format:

LeRobot v2.1 (e.g., box_closing_001):

{dataset_name}/data/chunk-000/episode_XXXXXX.parquet

• Episode filename: episode_{6-digit number}.parquet (zero-padded)

LeRobot v3.0 (e.g., part_sorting_long_756_episode):

{dataset_name}/data/chunk-000/file-XXX.parquet

• Data filename: file-{file_index}.parquet

• Dataset ID format: {action}_{description} (e.g., box_closing_001, part_sorting_long_756_episode)

Field definitions can be found in the main project at lerobot/common/policies/utils.py under observation/action definitions.

Dataset Naming Convention

Level	Format	Example
Task	/	Packing_box
Dataset Directory	{action}_{number}	box_closing_001/, box_closing_002/
Episode File	episode_{6-digit number}.parquet	episode_000000.parquet

When adding new datasets, increment the number sequentially (e.g., _001, _002, _003).
