rice-cooker_step_3 TsFile

This repository contains a TsFile conversion of the numeric time-series data from villekuosmanen/rice-cooker_step_3, while preserving the LeRobot episode-level repository layout.

Source Dataset

The source dataset was created using LeRobot.

Source: villekuosmanen/rice-cooker_step_3
License: apache-2.0
LeRobot codebase version: v2.1
Robot type: arx5
Episodes: 100
Frames: 53,492
Tasks: 1
FPS: 50
Video streams: observation.images.front, observation.images.wrist
Total videos: 200

The original numeric data is one Parquet file per episode:

data/chunk-000/episode_000000.parquet
...
data/chunk-000/episode_000099.parquet

Converted Layout

README.md
data/chunk-000/episode_000000.tsfile
...
data/chunk-000/episode_000099.tsfile
meta/info.json
meta/tasks.jsonl
meta/episodes.jsonl
meta/episodes_stats.jsonl
videos/chunk-000/observation.images.front/episode_000000.mp4
...
videos/chunk-000/observation.images.front/episode_000099.mp4
videos/chunk-000/observation.images.wrist/episode_000000.mp4
...
videos/chunk-000/observation.images.wrist/episode_000099.mp4

The meta/ and videos/ directories are mirrored from the source repository. Only the Parquet episode files are converted to TsFile.

TsFile Mapping

Table name: rice_cooker_step_3
TAG columns: episode_id, task_id
Time precision: milliseconds
Time definition: Time = round(timestamp * 1000)
timestamp is preserved as episode_timestamp_s
index is renamed to sample_index
observation.state[7] is flattened to state_0 ... state_6
action[7] is flattened to action_0 ... action_6
Row count preserved: 53,492 source rows -> 53,492 TsFile rows across 100 files

Video Alignment

Videos are not stored inside TsFile. They are mirrored under videos/ and aligned by episode and frame:

data/chunk-000/episode_000000.tsfile
videos/chunk-000/observation.images.front/episode_000000.mp4
videos/chunk-000/observation.images.wrist/episode_000000.mp4

Within an episode, frame_index aligns with the video frame index, and episode_timestamp_s aligns with video time in seconds.

Metadata

meta/info.json has been updated so:

"data_path": "data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.tsfile"

It also includes a tsfile_conversion object documenting the source path, converted path, TAG columns, time mapping, row count, and vector flattening.
