Human Experience Scales a Robot's Moving World

World models often separate locomotion from manipulation or bind themselves to one robot. Ropedia W0 represents movement with camera poses and manipulation with projected skeletons, combining 10,000 hours of human egocentric data with 3,000 hours of robot data. The authors report leading results across five cross-embodiment benchmarks and held-out human video, with additional human pretraining improving both human and robot evaluations. A distilled version produced real-time, minute-long rollouts for live virtual-reality interaction. The evidence is benchmark-based, but it suggests human motion can supply scale without pretending every body has the same joints.
