pick_tblock_mp_safe_margin_maxvel TsFile Conversion

This dataset is a TsFile conversion of younghyopark/pick_tblock_mp_safe_margin_maxvel, a LeRobot v2.1 DualPanda robot dataset.

Modalities: Time-series. The source metadata declares total_videos=0 and video_path=null.

Source Dataset Facts

From the original dataset card and meta/info.json:

  • Source dataset: younghyopark/pick_tblock_mp_safe_margin_maxvel
  • License: apache-2.0
  • Codebase version: v2.1
  • Robot type: DualPanda
  • Episodes: 1,000
  • Frames / converted rows: 243,000
  • Sampling rate: 50 fps
  • Split: train episodes 0:1000
  • Task: pick something up

Converted Files

  • data/pick_tblock_mp_safe_margin_maxvel.tsfile ? one merged TsFile containing all 1,000 episodes.
  • meta/ ? mirrored source metadata with meta/info.json updated to describe the TsFile artifact.

The generated TsFile size is 172,777,914 bytes.

TsFile Schema

  • Table name: pick_tblock_mp_safe_margin_maxvel
  • Time precision: milliseconds (ms)
  • Time: synthesized as round(timestamp * 1000). Time restarts per episode.
  • TAG columns: episode_index, task_index
  • Scalar FIELD columns: frame_index, sample_index (source index renamed).
  • Flattened FLOAT FIELD columns:
    • observation.joint[16] -> observation_joint_0 ? observation_joint_15
    • observation.state[30] -> observation_state_0 ? observation_state_29
    • observation.environment_state[7] -> observation_environment_state_0 ? observation_environment_state_6
    • observation.environment.block_xy[2] -> observation_environment_block_xy_0 ? observation_environment_block_xy_1
    • observation.right_arm.joint[7] -> observation_right_arm_joint_0 ? observation_right_arm_joint_6
    • observation.right.joint[8] -> observation_right_joint_0 ? observation_right_joint_7
    • observation.left_arm.joint[7] -> observation_left_arm_joint_0 ? observation_left_arm_joint_6
    • observation.qvel[30] -> observation_qvel_0 ? observation_qvel_29
    • observation.env_qvel[6] -> observation_env_qvel_0 ? observation_env_qvel_5
    • observation.ee_pose[16] -> observation_ee_pose_0 ? observation_ee_pose_15
    • action.ctrl[16] -> action_ctrl_0 ? action_ctrl_15
    • action.joint[16] -> action_joint_0 ? action_joint_15
    • action.ee_pose[16] -> action_ee_pose_0 ? action_ee_pose_15
    • action.right_arm.joint[7] -> action_right_arm_joint_0 ? action_right_arm_joint_6
    • action.right.joint[8] -> action_right_joint_0 ? action_right_joint_7
    • action.left_arm.joint[7] -> action_left_arm_joint_0 ? action_left_arm_joint_6

Conversion Notes

  • Converter: generic scripts/converters/lerobot.py.
  • Source timestamp is dropped after creating Time, because it equals Time / 1000 seconds.
  • Source index is renamed to sample_index.
  • Vector columns preserve source names by replacing . with _ and appending the element index.
  • All 243,000 source rows are preserved in the converted TsFile.
  • No video files are uploaded because the source metadata declares no videos.

Minimal Read Example 

# Use Apache TsFile tooling to read:
# data/pick_tblock_mp_safe_margin_maxvel.tsfile
# Query one episode with a predicate such as WHERE episode_index = 0.
