The Dynamixel AX-12A is an advanced and affordable servo motor for robotics. It has a slightly lower torque than the Dynamixel AX-18A but quite half the speed. The motor case is made of high quality plastic. The Dynamixel AX-12A is an improved version of the Dynamixel AX-12+ with the same performance but with a more advanced design. The AX-12A is a servomotor with additional features for robotics like the ability to track speed, temperature, shaft position, voltage and load. All of the build-in sensors are handled by the servo's embed microcontroller itself. The AX-12A is the entry level model of the Dynamixel AX series.
