BAP13 SO101 Test 3 TsFile

This is an Apache TsFile conversion of bap13/so101_test_3, a LeRobot v2.1 SO101 robot-manipulation dataset. The task is: Grasp a blue block and put it in the bowl.

Source Dataset and Provenance

Original dataset: bap13/so101_test_3
Original repository owner and uploader: Brett Peters (bap13)
License: Apache-2.0
Robot type: so101
LeRobot codebase version: v2.1
Split: train
Sampling rate: 30 fps
Scale: 53 episodes, 30,617 frame rows, 1 task, 53 source Parquet files, and 106 source videos
Source frame layout: data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet
Source video layout: videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4
Paper/citation: not supplied by the source dataset card

The source README contains an obsolete 3-episode example. The pinned repository files, meta/info.json, meta/episodes.jsonl, and all 53 Parquet shards agree on the current 53-episode, 30,617-row dataset.

Schema

Column	TsFile type	Role	Encoding	Compression
Time	TIMESTAMP	TIME	TS_2DIFF	LZ4
episode_index	STRING	TAG	Device/tag storage	Device/tag storage
task_index	STRING	TAG	Device/tag storage	Device/tag storage
frame_index	INT64	FIELD	TS_2DIFF	LZ4
sample_index	INT64	FIELD	TS_2DIFF	LZ4
action_0 through action_5	FLOAT	FIELD	GORILLA	LZ4
observation_state_0 through observation_state_5	FLOAT	FIELD	GORILLA	LZ4

The source index column is renamed to sample_index. frame_index is retained. episode_index and task_index are stored as TsFile table-model TAG/device columns.

Videos

Videos are not included in this TsFile dataset. They remain at the pinned source revision in two frame-aligned streams:

observation.images.context: 53 per-episode MP4 files, 202,287,802 bytes
observation.images.wrist: 53 per-episode MP4 files, 312,978,469 bytes

Together the 106 AV1 videos occupy 515,266,271 bytes (about 491.40 MiB). Both streams are 640 by 480 at 30 fps without audio. Numeric rows align with the source videos through episode_index and frame_index.

Minimal Read Example

from tsfile import TsFileReader

reader = TsFileReader("data/bap13_so101_test_3_train.tsfile")
table_name = "bap13_so101_test_3_train"
columns = [
    "episode_index",
    "task_index",
    "frame_index",
    "sample_index",
    "action_0",
    "observation_state_0",
]

with reader.query_table(table_name, columns, batch_size=65536) as result:
    batch = result.read_arrow_batch()
    print(batch.to_pandas().head())
reader.close()
