Can a wheel-legged robot choose a safer outdoor route by rehearsing its actions before moving? This episode explains how DEEP Robotics' DR-WM-1.0 connects terrain estimation, physics simulation, and generated observations—and how the accompanying navigation research fits around it. We examine three questions: why spatially varying contact properties matter; what DR-VLA learns from human egocentric video through EgoLynx; and how LynxScenes evaluates perception, navigation, prediction, and reconstruction on shared real-robot recordings. The discussion covers the LYNX M20 outdoor platform, controller-aware physical rehearsal, structured future-scene representations, and the relationship between real-to-sim calibration and sim-to-real transfer. We also unpack the distinction between evaluating predicted consequences and measuring autonomous deployment. The central limitation is that recorded-command prediction and pseudo-closed-loop replay do not establish that rehearsal improves an executing robot's decisions over an evolving mission. For researchers building world models, VLA policies, or outdoor navigation systems, the practical question is clear: what should a robot predict to make its next action better?
