Researchers have developed SLAC, a novel method for training complex robots using reinforcement learning. SLAC leverages a low-fidelity simulator to pre-train a task-agnostic latent action space, promoting temporal abstraction and safety. This pre-trained space then serves as the interface for an off-policy RL algorithm, enabling efficient learning of downstream tasks through real-world interactions. SLAC has demonstrated state-of-the-art performance on bimanual mobile manipulation tasks, learning complex, contact-rich behaviors in under an hour without demonstrations. AI
