Body, not brain: How design flaws stop humanoid robots from leaving the lab

SMRTR summary

Despite advances in humanoid robots, experts argue their rigid bodies—not just AI limitations—prevent widespread adoption. Humanoid robots consume excessive power making basic movements because they lack "mechanical intelligence" found in nature. Sony and researchers like Hamed Rajabi advocate for flexible joints, spring-like tendons, and adaptive materials that would allow robots to move naturally while using less energy, enabling them to function effectively outside controlled environments.
