pi0_stationary_cube_fixed (TsFile)

Apache TsFile version of woosw123/Pi0_Stationary_Cube_fixed.

Overview

A LeRobot robot-manipulation dataset — a stationary dual-arm cube manipulation task recorded for Pi0 policy learning. The source card is auto-generated ("This dataset was created using LeRobot") and does not add a free-text description; the facts below are taken from the source meta/info.json.

• Robot: stationary dual-arm
• Episodes: 100
• Frames: 39133
• Sampling rate: 30 fps
• Tasks: 1
• Splits: a single train split (0:100)

Schema (TsFile structure)

• Time (INT64, milliseconds) — round(timestamp * 1000); the source timestamp column (seconds) is dropped because it equals Time / 1000.
• episode_index (TAG), task_index (TAG) — device dimensions; query one episode with WHERE episode_index = <n>.
• frame_index (FIELD, INT64), sample_index (FIELD, INT64, from the source index) — per-frame bookkeeping.
• Vector columns (single-precision FLOAT, source name with . → _ and an element index appended):
  • observation.state → observation_state_0..observation_state_13 (FLOAT)
  • action → action_0..action_13 (FLOAT)

Camera video streams are not included in this repository; see the original dataset for the videos: https://huggingface.co/datasets/woosw123/Pi0_Stationary_Cube_fixed (videos/ directory).
