Composite ring gears are used on some new robotic arms. Metal ring gear is installed inside fiber reinforced composite housing – carbon fiber robot arm. The metal ring gear is part of a rotary gear actuator that moves the arm. Using carbon fiber reinforced composite arm/gear housing reduces inertia of the robot. KUKA makes a robot with carbon composite ring gear design.
