Jetson1 060326 TsFile

This dataset is an Apache TsFile conversion of VibeCuisine/jetson1-060326, a LeRobot v3.0 robot dataset.

Modalities: Time-series. The converted repository contains numeric robot observations, actions, frame timing, task/episode tags, and source metadata. Camera videos remain in the original Hugging Face dataset.

Source Dataset

Source dataset: VibeCuisine/jetson1-060326
License: Apache-2.0
Robot type: vibeboard_follower_tilt
LeRobot codebase version: v3.0
Split: train
Scale: 3 episodes, 939 frames, 1 task, 20 fps
Source frame 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
Task metadata: grab the cucumber close to one of the cucumber's end

Converted Files

TsFile: data/jetson1_060326.tsfile
Table: jetson1_060326
Rows: 939
Episodes: 3
Time precision: milliseconds
Metadata: meta/ is mirrored from the source, with meta/info.json updated to describe the converted TsFile artifact.

Schema

Time is synthesized as round(timestamp * 1000) milliseconds and restarts within each episode.

TAG columns:

episode_index
task_index

Scalar FIELD columns:

frame_index
sample_index, renamed from the source index

Flattened FLOAT FIELD groups:

action[7] -> action_0 ... action_6
observation.state[7] -> observation_state_0 ... observation_state_6

The 7 action and observation-state dimensions follow the source order:

shoulder_pan.pos
shoulder_lift.pos
elbow_flex.pos
wrist_flex.pos
wrist_roll.pos
gripper.pos
tilt.pos

Conversion Notes

The generic lerobot converter was used.
All source frame Parquet shards are merged into one TsFile table. Use episode_index and task_index TAG filters to select an episode or task.
Vector columns are flattened to scalar TsFile fields. Source column prefixes are preserved, with . replaced by _.
The source timestamp column is dropped after Time synthesis because it is redundant with Time / 1000 seconds.
The source index column is renamed to sample_index.
Source camera video streams are not included in this repository: observation.images.top, observation.images.wrist, and observation.images.base. They remain available in the original dataset under videos/.
No rows and no numeric time-series fields are intentionally dropped other than the redundant timestamp column noted above.

Usage

Read the TsFile with Apache TsFile tools or SDKs. Example path:

data/jetson1_060326.tsfile

To inspect a single episode in SQL-style tools, filter by the TAG:

SELECT *
FROM jetson1_060326
WHERE episode_index = 0;
