Researchers have developed REGRIND, a new reinforcement learning pipeline designed to enable robots to perform dexterous manipulation tasks using human demonstrations. This method retargets human hand-object motion to a robot reference, preserving spatial and contact relationships. A residual reinforcement learning policy is then trained in simulation to track keypoints, which is then transferred to physical hardware with zero-shot accuracy. The system has successfully demonstrated fluid, human-like manipulation with multi-fingered hands on tasks such as using scissors and a screwdriver, offering insights into sim-to-real transfer for contact-rich scenarios.
