Researchers have developed LUCID, a novel hierarchical model-based reinforcement learning framework designed for complex, long-horizon tasks involving humanoid robots. This system addresses limitations in current methods by enabling the composition of versatile whole-body skills and reliable high-level decision-making. LUCID achieves this by learning a dynamics model that predicts state transitions based on latent decisions, allowing for optimized high-level policy planning through imagined rollouts. Evaluations in simulated multi-object rearrangement scenarios demonstrated LUCID's superior performance in full-task success and partial-completion rates compared to existing baseline approaches. AI
