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:

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()
