Part 2/10:
Tesla's design incorporates actuators primarily located in the forearm, allowing for fingers of varying lengths. This configuration, which even includes a shorter pinky, dramatically enhances the robot's overall dexterity, particularly in tasks requiring fine force control. The Optimus Gen 3 has 22 degrees of freedom in each hand, with this intricate setup being developed using physics-based principles, sensors, and components built from scratch. The forearm housing is essential hardware for hand movement, including springs and pivots that contribute to the robot's stability and precision.
