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;
