The arm pushes around modular objects that can be adjusted for weight, shape, and mass distribution. For each push, the system captures how those characteristics affect the robot's push. > The dataset, called "Omnipush," contains 250 different pushes of 250 objects, totaling roughly 62,500 unique pushes. It's already being used by researchers to, for instance, build models that help robots predict where objects will land when they're pushed.
