Researchers have developed a new method called RARM (Reference-Anchored Reward Model) to improve reinforcement learning for robot manipulation tasks. RARM uses a single successful demonstration to create a progress-aware reward signal, eliminating the need for task-specific demonstrations or manual reward engineering. This approach has shown superior success rates across simulated and real-world manipulation tasks, particularly excelling in complex, long-horizon tasks like cloth folding where accurate progress estimation is crucial.
