Tesla’s Optimus robot has once again captured attention, but recent reports highlight significant production bottlenecks, specifically centered on the robot’s hands rather than its legs, AI, or sensors. The hands of the Optimus robot face challenges such as low load capacity, a short lifespan for transmission components, and difficulties in integrating precision mechanics, miniature actuators, and AI-driven control systems. This bottleneck underscores a critical challenge in robotic development, emphasizing that human-like dexterity, rather than merely a humanoid shape, is the key to achieving versatile robotic functionality. The current hand design, limited to 11 degrees of freedom, falls short of the human hand’s approximately 25 degrees, restricting the robot’s ability to perform complex tasks effectively.
