According to Sawyer Merritt on Twitter, Elon Musk revealed in a recent interview that Tesla's Optimus robot now features a hand with the same degrees of freedom as a human hand, something not seen in current demo robots. Musk stated that achieving this required Tesla to develop custom actuators, motors, gears, power electronics, and sensors. This advancement highlights Tesla's commitment to robotics innovation and could accelerate practical use cases for humanoid robots in industries requiring precise manipulation, as reported by Sawyer Merritt.
