The first three covered the basic concepts of world models, the core principles of RSSM, and an introduction to embodied AI. Today, we&rsquo;re diving into a more practical topic: how do we actually deploy policies trained in simulation onto real robots?</p> <p>This problem has plagued the robotics AI field for nearly a decade. World models perform brilliantly in simulated environments — DreamerV3&rsquo;s sample efficiency is 10-100x higher than traditional RL. But once deployed on real robots, performance often drops by 30-50%. This gap is the famous &ldquo;Sim-to-Real Gap&rdquo;.</p>
