Tesla Owners Silicon Valley(@teslaownersSV):Elon Musk on why the hand is the hardest part of building Optimus: "The hands in Optimus are half or more than half of the electromechanical problem, and the entire rest of the body is a half." Almost all the muscles that move your fingers sit in your forearm and pull through tendons. As Elon put it, "your hand is being operated like a marionette from your forearm." Building a humanoid robot means rebuilding that. @elonmusk Video: Tesla Owners Silicon Valley, X Takeover 2025
