glaxealiter1_plugcharger_depth
Five operator-selected Galaxea R1 Lite demonstrations recorded on 2026-10-30 (Asia/Hong_Kong). Task label plugcharger was supplied by the operator; physical task success is not independently certified. Original chronological episode 3 is excluded.
Contents
Raw ROS 2 MCAPs, original metadata.yaml, native recorder JSON sidecars and wrist_depth_collection.json. Both aligned wrist-depth streams use 16UC1 millimetres at 848x480, with wrist color and aligned/color CameraInfo, corrected stereo head RGB, robot control/state topics and static TF. Wrist streams were configured at 30Hz. See included_manifest.jsonl for exact per-episode duration, counts, arrival coverage and SHA256 identities.
Source timestamps/frames/units were preserved. Native packaging sometimes leaves metadata.yaml relative_file_paths referring to the original _0.mcap name although the actual file is renamed; open the actual MCAP file directly. Raw files were not repaired or rewritten. This is raw storage, not a LeRobot-converted dataset.
Privacy, license and limitations
Public repository published with the operator's explicit authorization on 2026-10-30. Raw cameras contain the laboratory and may contain people, screens or labels. A limited review sampled start/midpoint/late frames from all four RGB cameras in all five included episodes; this is not an exhaustive privacy review. No reusable license was supplied. Do not infer permission for public redistribution or reuse from access.
The collection pipeline experienced intermittent wrist USB timeouts outside some saved episodes. Required sensor coverage was inspected before release; autonomous task success, geometric calibration accuracy and action/state alignment for training were not independently certified. Never replay command topics while connected to a live robot.
