This sample of Pantheon DiverseUMI contains 25 hours of bimanual tabletop manipulation recorded with two handheld UMI grippers and an exocentric top camera. Each episode is a single task, such as stacking two blocks or passing a ball between grippers. Every episode includes three synchronized videos (top camera and both wrist cameras), per-frame end-effector actions for both wrists, and dense annotations of what the operator does.
