Human Video Teaches the Robot Through Imagined Consequences
ThinkWorld turns proposed actions into discrete motion chains, predicts their future state and rewards chains that match observed outcomes.
Summary
ThinkWorld turns proposed actions into discrete motion chains, predicts their future state and rewards chains that match observed outcomes.
Robot demonstrations carry actions but are expensive; human videos are abundant but do not expose robot commands. ThinkWorld represents an action thought as a chain of discrete motion tokens connecting the current scene to a future state. It initializes those chains from action-labeled demonstrations, predicts the future each chain would induce and reinforces chains whose predicted outcome matches an observed video transition. That lets human and robot videos refine the same action-reasoning space. Simulation and real-robot experiments show transfer to unseen tasks and environments, though the abstract does not make this a general solution for arbitrary embodiments.
