light_candle_3c (TsFile)

Apache TsFile version of ming326/light_candle_3c.

Overview

A LeRobot robot-manipulation dataset — a light-the-candle manipulation task (3 cameras). 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: (unspecified)
• Episodes: 50
• Frames: 13355
• Sampling rate: 15 fps
• Tasks: 1
• Splits: a single train split (0:50)

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_7 (FLOAT)
  • observation.actions → observation_actions_0..observation_actions_7 (FLOAT)
  • actions → actions_0..actions_7 (FLOAT)
  • grasp_phase_onehot → grasp_phase_onehot_0..grasp_phase_onehot_3 (FLOAT)

Camera video streams are not included in this repository; see the original dataset for the videos: https://huggingface.co/datasets/ming326/light_candle_3c (videos/ directory).
