aloha_static_candy

This dataset converts the numeric time-series from lerobot/aloha_static_candy to Apache TsFile format.

Dataset Description

The source dataset was created using LeRobot. It is an ALOHA robot dataset published by the LeRobot team.

• Source dataset: lerobot/aloha_static_candy
• Project: 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:

Use episode_index, frame_index, and Time to align TsFile rows with the original videos.
