Researchers have developed REFINE-DP, a novel hierarchical framework designed to enhance humanoid robot capabilities in loco-manipulation tasks. This approach integrates diffusion policies (DPs) with reinforcement learning (RL) by fine-tuning the DP motion planner using a PPO-based gradient. Simultaneously, an RL-based controller is updated to accurately track the planner's commands, thereby reducing distributional mismatch. The system has demonstrated over 90% success rates in simulations for tasks like door traversal and object transport, even in out-of-distribution scenarios, and has been successfully executed on real-world humanoid robots.
