First-Person Bench Work Video, Brazil (0.5 h starter set)

# First-Person Bench Work Video, Brazil (Trades) Head-mounted phone video of bench work in Brazil (painting objects, nail care), with the wearer's hands in frame. ## At a glance | | trades | |---|---| | Recordings | 3 | | Episodes | 11 | | Hours | 0.48 | | People | 1 | | Tasks | 2 | ## Capture - Phone on a head mount, ultra-wide lens requested, landscape. 1920x1080 for every episode. - One phone model: Samsung SM-G990E. - No audio: no video file in this dataset has an audio track. - Environments declared by the person recording: salon and workshop bench. ## Hands Measured on one frame per second of everything delivered. - At least one hand visible 97.9% of the time, both hands 92.8%. Every recording has one or more hands in at least 90% of its time. - Per episode: `hands_any_pct` and `hands_two_pct` in the episode manifest (`trades.lerobot/package/metadata/episodes.jsonl`). ## Annotations - Task label per recording. - Task steps: 117 steps in 11 of 11 episodes, each with start, end, verb, object, acting hand and one sentence in English and in Portuguese. AI-generated and marked `annotation_source: ai_generated`; 19 validated by people (`human_validated: true`). - Camera intrinsics for all 3 recordings, self-calibrated (`intrinsics_origin`). None measured with a calibration target. ## Formats and folder structure ``` trades.lerobot/ <h264 root>/ LeRobotDataset v3 root: meta/, data/, videos/ (11 episodes, 11 video files) derived/ frame maps of re-sampled episodes package/ manifests, QA report, consent ledger, terms, Croissant card index.json episode_index to episode_id, byte copy or derived ``` - The LeRobot root is the only folder in `trades.lerobot/` whose name ends in `-h264`; its name gives resolution, frame rate and codec. - One LeRobot v3 root, 11 episodes in 11 video files. Camera key `observation.images.egocentric`. Tables carry `timestamp`, `frame_index`, `episode_index`, `index`, `task_index`. This is human video: no `action` or `observation.state` column. - Every episode is H.264 at exactly 30 fps. 3 episodes are byte copies of the phone file; 8 recorded at a variable or non-integer rate were resampled to 30 fps and re-encoded in H.264 (CRF 18). `index.json` marks each one and `derived/<episode_id>.frames.csv.gz` maps every frame to its source frame. - Episode length from 61.4 s to 180 s. - Croissant 1.1 card with the Responsible AI extension in `trades.lerobot/package/croissant.json`. ## Loading ```python from pathlib import Path from lerobot.datasets import LeRobotDataset root = next(Path("trades.lerobot").glob("*-h264")) ds = LeRobotDataset("local/trades", root=root) ``` ## Not included No audio, IMU, depth, camera pose or 3D hand pose. No robot actions. ## Rights and consent - First-party collection. The person recording is an adult who accepted written participation terms covering recording, AI training, commercial licensing and sublicensing. - Each recording links to the terms version and the SHA-256 of the accepted text in `trades.lerobot/package/consent_ledger.csv`; the terms text is in `trades.lerobot/package/terms/`, with an English courtesy translation. - Before delivery a person watched every recording to the end and confirmed there is no other person's face, reflection, document or screen with personal data. - Participant ids are pseudonymous and valid only inside this dataset. ## License Kinetic Blocks Commercial Standard licence, non-exclusive.
