Researchers have developed a new reinforcement learning framework called Stubborn, designed to improve the motion tracking and fall recovery capabilities of humanoid robots. Unlike previous methods that treated these as separate tasks requiring complex multi-stage training, Stubborn unifies them into a single framework. It incorporates a novel probabilistic termination mechanism to encourage exploration of recovery behaviors and an adaptive sampling strategy that focuses training on difficult motion segments and unstable states, leading to more robust performance.
