Researchers have developed HydroShear, a novel hydroelastic simulator designed to improve the accuracy of tactile feedback in reinforcement learning for robotics. This simulator models complex phenomena like stick-slip transitions and path-dependent force build-up, offering a more realistic representation of shear forces compared to existing methods. When tested with GelSight Minis, HydroShear enabled zero-shot sim-to-real transfer for four dexterous tasks, achieving a 93% success rate, significantly outperforming policies trained on tactile images or alternative shear simulation techniques.
