Sanctuary AI claims an ‘order of magnitude’ improvement for the robot hands on its Phoenix humanoid robots.

The company’s dexterous robotic hands, with 21 degrees of freedom (DOF), can now perform in-hand manipulation, expanding the range of industrial fine manipulation tasks. This success is made possible by Sanctuary’s unique miniaturized hydraulic valves. These valves offer a higher power density than traditional cable and electromechanical systems, granting the robot exceptional speed, strength, control, and durability, including heat management and impact resistance. Demonstrating in-hand manipulation with a scalable, reliable system is a crucial milestone in advancing general-purpose robots.
