According to Sawyer Merritt, Tesla’s Optimus V3 robot hand appears in a newly published international patent outlining a tendon or cable-driven architecture with forearm-mounted actuators, four degrees of freedom per finger, and a two-degree-of-freedom wrist. As reported by the patent filing referenced by Merritt, relocating actuators to the forearm reduces finger inertia and enables finer manipulation through differential tendon routing, a design that can improve grasp stability and in-hand reorientation. According to industry analysis of tendon-driven hands cited by the patent context, this approach can lower end-effector mass and cost compared with fully embedded finger actuators, creating potential advantages for high-volume humanoid manufacturing. As reported by Merritt, the multi-DoF layout suggests Tesla is targeting dexterous tasks like cable handling, tool use, and pick-and-place in factories, which could expand Optimus’ addressable market in electronics assembly and general logistics. According to the patent summary shared by Merritt, a 4-DoF finger stack (including abduction and flexion) plus a 2-DoF wrist may enable human-like precision grips and power grips, a prerequisite for commercial deployments in parts kitting and line-side material flow.
