What is Assembly101?
Assembly101 captures the full complexity of procedural assembly tasks. Participants assemble and disassemble take-apart toys while being recorded from 12 synchronized cameras -- 8 fixed external views and 4 head-mounted egocentric cameras. The multi-view setup provides complete 3D coverage of hand-object interactions during assembly.
The annotation depth is exceptional: 100K+ coarse action labels, 1M+ fine-grained temporal segments, and 3D hand pose estimates. This makes Assembly101 uniquely valuable for manufacturing robotics research, where robots need to understand assembly sequences, detect errors, and plan corrective actions.
