aloha_mobile_shrimp

This dataset was converted from lerobot/aloha_mobile_shrimp to Apache TsFile format.

Dataset Description

The original dataset was created using LeRobot.

Homepage: More Information Needed
Paper: More Information Needed
License: apache-2.0

Source Dataset

Original dataset: lerobot/aloha_mobile_shrimp
Source scale: 18 episodes, 67,500 frames, 50 fps, 1 task.
Source robot type: aloha.
Source data path: data/chunk-{chunk_index:03d}/file-{file_index:03d}.parquet
Source video path: videos/{video_key}/chunk-{chunk_index:03d}/file-{file_index:03d}.mp4

TsFile Conversion

The numeric robot state/action/time/task data was converted into one TsFile:

data/aloha_mobile_shrimp.tsfile

Conversion details:

All 18 source episodes are stored in one TsFile table named aloha_mobile_shrimp.
episode_index and task_index are TsFile TAG columns. Query a single episode with WHERE episode_index=N.
Time = round(timestamp * 1000) in milliseconds. The source timestamp column is not retained because it equals Time / 1000 seconds.
frame_index is kept. Source index is renamed to sample_index. Source next.done is renamed to next_done.
Vector columns are flattened by preserving the source column name, replacing . with _, and appending the element index.
Values from flattened vector columns are stored as single-precision FLOAT.

Flattened vector features:

observation.state[14] -> observation_state_0..observation_state_13
observation.effort[14] -> observation_effort_0..observation_effort_13
action[14] -> action_0..action_13

Videos

Videos are not included in this TsFile repository. They remain in the original dataset under videos/.

The mirrored meta/info.json records the original video path and includes a tsfile_conversion section describing the converted schema, row count, tag columns, dropped timestamp column, omitted video features, and time mapping.
