LeKiwi PickCube Test TsFile

This dataset is an Apache TsFile conversion of oumeanin/lekiwi-pickcube-test, a LeRobot v3.0 LeKiwi mobile-manipulator dataset.

The converted artifact contains tabular time-series robot state, action, frame, episode, and task data. Camera videos remain in the original Hugging Face dataset and are not duplicated here.

Source Dataset and Author

Original dataset: oumeanin/lekiwi-pickcube-test
Pinned source revision: d904800f111d7f6724cc7ab21ab5bc4a3ad60ddf
Original repository owner and uploader: oumeanin
License: Apache-2.0
Robot type: lekiwi_soarm
LeRobot codebase version: v3.0
Task: LeKiwi pick-cube test demonstrations
Split: train
Sampling rate: 30 fps
Scale: 50 episodes, 185,664 frame rows, 1 task, 1 Parquet data shard
Source data layout: data/chunk-{chunk_index:03d}/file-{file_index:03d}.parquet
Source video layout: videos/{video_key}/chunk-{chunk_index:03d}/file-{file_index:03d}.mp4

The source card does not provide a paper, completed citation, or a separate formal author list. Repository ownership and commit history identify oumeanin as the source publisher.

Converted Files

TsFile: data/oumeanin_lekiwi_pickcube_test_train.tsfile (975,363 bytes)
Table: oumeanin_lekiwi_pickcube_test_train
Rows: 185,664
Episode/task devices: 50
Time precision: milliseconds
Metadata: meta/ is mirrored from the source, with meta/info.json updated for the TsFile artifact

TsFile Schema

Time is INT64 milliseconds computed as round(timestamp * 1000). It restarts at zero for each episode.

TAG columns, stored through the TsFile table device/TAG mechanism:

episode_index
task_index

Scalar INT64 FIELD columns:

frame_index
sample_index, renamed from source index

Flattened FLOAT FIELD groups:

action[9] -> action_0 ... action_8
observation.state[9] -> observation_state_0 ... observation_state_8

The nine dimensions in both groups are: shoulder_pan.pos, shoulder_lift.pos, elbow_flex.pos, wrist_flex.pos, wrist_roll.pos, gripper.pos, base_vx_mps, base_vy_mps, base_theta_degps.

Encoding and Conversion Notes

FLOAT/DOUBLE fields use GORILLA + LZ4.
INT32/INT64 fields and Time use TS_2DIFF + LZ4.
BOOLEAN fields use RLE + LZ4 when present; this source has no BOOLEAN field.
Source episode_index and task_index are TsFile TAGs.
All source rows are merged into one train TsFile and sorted by TAGs then Time.
Vector columns are flattened to scalar fields; dots become underscores.
Source timestamp is dropped after Time synthesis because it equals Time / 1000 seconds.
Source index becomes sample_index; frame_index is kept.
No numeric row or state/action dimension is dropped.
The TsFile is 0.3252 times the source Parquet size.

Videos

Videos are not included in this TsFile repository. The source contains two frame-aligned AV1, 640x480, 30 fps streams without audio, each with ten MP4 shards:

observation.images.base - file-000.mp4 through file-009.mp4
observation.images.wrist - file-000.mp4 through file-009.mp4

The source path template is videos/{video_key}/chunk-{chunk_index:03d}/file-{file_index:03d}.mp4. episode_index, frame_index, and meta/episodes/ preserve alignment between numeric rows and the original video frames.

Validation

Apache TsFile Java 2.2.1 performed a full query readback of all 185,664 rows. The validator also checked the table schema, TAG columns, per-column physical encoding/compression, Time encoding/compression, unique TAG+Time keys, vector widths, and monotonic Time within every episode. Reports remain local and are not part of this upload-ready directory.

Minimal Read Example

from tsfile import TsFileReader

reader = TsFileReader("data/oumeanin_lekiwi_pickcube_test_train.tsfile")
table_name = "oumeanin_lekiwi_pickcube_test_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()
