Elon Musk on why Optimus is so brutally hard to build (hardware side): “The hands are the majority of the engineering difficulty of the entire robot.” Human hands evolved insane sophistication — ~27–28 degrees of freedom, complex tendon web (mostly forearm muscles), crazy dexterity. No supply chain exists. Tesla had to design every single actuator, motor, gearbox & electronics from physics first principles. “Harder than Cybertruck or Model X… somewhere between Model X and Starship.” Optimus v3 finally aiming for true human-level hand performance. The “hands problem” is massively underestimated.
