Co-Design Insight: Sizing humanoid robot power architectures requires simultaneous balance of AI compute TDP vs actuator peak back-EMF, battery IR self-heating ($I^2R_{pack}$), and active cooling COP. Increasing ambient temp directly compresses thermal headroom before Thor compute throttling kicks in at 85°C.
