First Task Short TsFile
This dataset is an Apache TsFile conversion of
pietroom/first_task_short, a LeRobot v2.1 SO100
robot-manipulation dataset for passing a marker.
Source Dataset and Attribution
- Original dataset:
pietroom/first_task_short - Original author, repository owner, uploader, and video contributor: pietroom
- License: Apache-2.0
- Task: "Pass the marker."
- Robot:
so100; LeRobot version:v2.1 - Split:
train; sampling rate: 30 fps - Scale: 90 episodes, 53,830 frames, 1 task
- Source shards: 90 Parquet files totaling 2,911,374 bytes
- Source layout:
data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet - The source card provides no paper, external homepage, or completed citation.
Data Summary
- Path:
data/pietroom_first_task_short.tsfile - Table:
pietroom_first_task_short - Rows: 53,830; episodes/devices: 90; tasks: 1
- Time precision: milliseconds
- TsFile/source-Parquet size ratio: 0.366
Schema and Mapping
Time = round(timestamp * 1000) milliseconds. Time starts at zero and is
strictly increasing in every episode. The source timestamp is omitted after
conversion because it is recoverable as Time / 1000 seconds.
| TsFile column | Role | Type | Source mapping |
|---|---|---|---|
Time |
TIME | TIMESTAMP | round(timestamp * 1000) ms |
episode_index |
TAG | STRING | Original INT64 episode index |
task_index |
TAG | STRING | Original INT64 task index |
frame_index |
FIELD | INT64 | Preserved |
sample_index |
FIELD | INT64 | Renamed from index |
action_0 ... action_5 |
FIELD | FLOAT | Flattened from action[6] |
observation_state_0 ... observation_state_5 |
FIELD | FLOAT | Flattened from observation.state[6] |
The six vector dimensions are main_shoulder_pan, main_shoulder_lift,
main_elbow_flex, main_wrist_flex, main_wrist_roll, and main_gripper.
Dots in source names are replaced by underscores. No numeric row, episode,
task, action dimension, or state dimension is dropped.
Encodings and Compression
- FLOAT/DOUBLE: GORILLA + LZ4
- INT32/INT64: TS_2DIFF + LZ4
- Time: TS_2DIFF + LZ4
- BOOLEAN: RLE + LZ4 (the source has no BOOLEAN field)
- TAG: TsFile table/device TAG storage
Videos
Videos are not included in this TsFile dataset. The 180 original AV1 MP4 files remain in the source repository, 640x480 at 30 fps with no audio, in two streams with 90 episode files each:
The source layout is
videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4.
Use episode_index and frame_index to align numeric rows with video frames.
Minimal Read Example
from tsfile import TsFileReader
reader = TsFileReader("data/pietroom_first_task_short.tsfile")
with reader.query_table(
"pietroom_first_task_short",
["episode_index", "task_index", "frame_index", "sample_index",
"action_0", "observation_state_0"],
batch_size=65536,
) as result:
batch = result.read_arrow_batch()
print(batch.to_pandas().head())
reader.close()
Citation
The source card supplies no paper or completed citation. Cite the original
Hugging Face dataset and its publisher, pietroom, when using this conversion.
