Opening a Box with a Utility Knife - Egocentric Human Demonstration

A single continuous egocentric demonstration of a person opening a cardboard box with a utility knife and unpacking its contents. Captured with a head-mounted camera plus two forearm-strapped wrist cameras, all 1920×1080 H.264 at 30 fps. Packaged as a HuggingFace LeRobot v2.1 dataset: 1 episode, 9,616 frames (5.34 min) — the longest episode in this collection — QC-complete with 0 Tier-1 FAILs. The parquet carries per-frame hand-pose annotation — 21-point 3D and 2D landmarks for both hands with per-landmark confidence and visibility, handedness scores — plus semantic action labelling: action phase, verb and noun with an LLM-generated reasoning trace, and a detected primary object with bounding box and hand-distance. 59 columns over 9,616 rows. The episode is further segmented into 65 annotated action windows, the densest annotation in the collection. Notable for precision tool use under safety constraint (blade control) and a clean, unambiguous end state.
