Researchers have introduced ContactFlow, a novel action representation for robot planning that focuses on the trajectory of 3D contact points between an actor and an object. This embodiment-agnostic approach allows for the transfer of manipulation skills between human demonstrations and different robotic embodiments. By training a large-scale video generative model on both human and robotic interaction videos conditioned on ContactFlow, the system can predict physically plausible manipulation outcomes and has been demonstrated on the DROID dataset and real-world tasks.
