Actuators are the robot's muscles and joints, and they can be up to half the cost of a humanoid. The chain is 5 layers deep: magnets, motors, reducers, roller screws, and assembly. $MP MP Materials runs America's only rare earth mine at scale. Harmonic Drive Systems saw orders up 56% last quarter. A single planetary roller screw can cost up to $2,700, and JP Morgan says screws and reducers alone are a third of the robot.
