pick_tblock_mp_pdscale_20_new2 TsFile

This dataset is a TsFile conversion of the LeRobot dataset younghyopark/pick_tblock_mp_pdscale_20_new2. The source dataset was created with LeRobot and is licensed under apache-2.0.

Dataset Details

• Source dataset: younghyopark/pick_tblock_mp_pdscale_20_new2
• Source format: LeRobot v2.1
• Robot type: DualPanda
• Modalities: Time-series robot state and action data
• Split: train
• Episodes: 1000
• Frames / rows: 153000
• Tasks: 1
• Sampling rate: 50 fps
• Source videos: 0 (video_path: null)
• Converted data file: data/pick_tblock_mp_pdscale_20_new2_train.tsfile

TsFile Layout

The conversion writes one TsFile table for the train split: pick_tblock_mp_pdscale_20_new2_train.

• Time is the TsFile time column in milliseconds.
• episode_index and task_index are TAG columns.
• frame_index and sample_index are scalar FIELD columns.
• Vector features are flattened into scalar FIELD columns.

Vector column flattening preserves the source column name, replaces . with _, and appends the element index. For example, observation.state becomes observation_state_0 through observation_state_29.

Flattened source vectors:

• observation.state: 30 float32 fields
• observation.environment_state: 7 float32 fields
• action.relative_ee_pose: 16 float32 fields
• observation.qvel: 30 float32 fields
• observation.env_qvel: 6 float32 fields
• observation.ee_pose: 16 float32 fields
• action.ctrl: 16 float32 fields
• action.qpos: 16 float32 fields
• action.relative_qpos: 16 float32 fields
• action.ee_pose: 16 float32 fields

Conversion Notes

• Time = round(timestamp * 1000) and restarts per episode.
• The source timestamp column is dropped because it is represented by Time / 1000 seconds.
• The source index column is renamed to sample_index.
• No numeric time-series rows are dropped; the converted TsFile has 153000 rows.
• Source meta/ files are mirrored, with meta/info.json updated to describe the converted TsFile artifact.
• No videos are uploaded here. The source metadata reports total_videos: 0 and video_path: null.

Read Example

Use the Apache TsFile SDK or TsFile tools to read:

data/pick_tblock_mp_pdscale_20_new2_train.tsfile

For episode-level filtering, query the table with the TAG column, for example WHERE episode_index = 0.
