Embodiment-aware models
Work on control now puts body structure into the model, not just into the hardware description. QWM conditions a quadruped world model on explicit morphology features from the robot's USD file, with claims of zero-shot deployment on unseen quadrupeds inside the trained family. HEX does something similar for humanoids at the policy level: it maps different robots into shared body-part slots and predicts short-horizon future proprioception before acting. Both papers target cross-embodiment transfer by making morphology a first-class input. The evidence is promising, but neither excerpt includes the full numeric gains needed to judge how far the transfer holds under harder body changes.
