Morphology-conditioned world-model paper analyzes transfer from Spot to Unitree Go1

Evidence notes
- The paper proposes morphology conditioning for quadrupedal world models to reduce hardware lock-in.
- It analyzes how a world model trained on Boston Dynamics Spot fails on Unitree Go1 without embodiment-aware conditioning.
Company context
Boston Dynamics builds high-performance mobile robots including Spot for industrial and field inspection, Stretch for warehouse trailer unloading, and Atlas for advanced humanoid mobility.
