324_goofyparis_fetch

This dataset is a TsFile conversion of LeRobot-worldwide-hackathon/324-goofyParis-fetch, a LeRobot SO-101 follower robot dataset for the task fetch.

Source Dataset

• Original dataset: LeRobot-worldwide-hackathon/324-goofyParis-fetch
• Original license: apache-2.0
• Robot type: so101_follower
• Modalities: Time-series
• Source sampling rate: 30 fps
• Source scale from meta/info.json: 55 episodes, 13,338 frames, 1 task
• Source split: train episodes 0:55
• Source videos: 110 videos in the original dataset under videos/

The source task list is:

• task_index=0: fetch

TsFile Conversion

The converted dataset stores the numeric robot time-series data in one TsFile:

• data/324_goofyparis_fetch.tsfile

Conversion summary:

• Rows: 13,338
• Episodes: 55
• Time precision: milliseconds
• Table name: 324_goofyparis_fetch
• TAG columns: episode_index, task_index
• Time mapping: Time = round(timestamp * 1000)
• Dropped source column: timestamp, because it is represented by Time / 1000
• Renamed source column: index to sample_index
• Omitted source video features: observation.images.side, observation.images.hand

The meta/ directory is mirrored from the source dataset, with meta/info.json updated to describe the converted TsFile artifact and the video policy. Videos are not included in this converted repository; use the original dataset if frame-aligned videos are needed:

Schema

Time is the TsFile time column in milliseconds. episode_index and task_index are TAG columns. Remaining columns are FIELD measurements:

• frame_index
• sample_index
• action_0 through action_5
• observation_state_0 through observation_state_5

The 6 action and observation-state dimensions follow the source joint order:

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

Vector columns preserve the full source column name when flattened: . is replaced with _ and the element index is appended. For example, observation.state becomes observation_state_0..observation_state_5, and action becomes action_0..action_5.

Usage

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

data/324_goofyparis_fetch.tsfile

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

SELECT *
FROM `324_goofyparis_fetch`
WHERE episode_index = 0;
