DYNAMIXEL AX-12W

General

ROBOTIS is a well-known manufacturer of robotics development platforms and components. This company also manufactures industrial quality servo motors and interfaces under the name DYNAMIXEL. The AX-12W servo motors are equipped with an integrated reduction ratio of 32:1, a controller with feedback and driver. In combination with the half duplex interface, the servos can be controlled very precisely and also provide the control unit with feedback on the current position at all times. The maximum resolution (position accuracy) is 1024 divisions. As each servo can be assigned a unique ID, the servos can be connected in series (one behind the other, as shown below) and the wiring is reduced to a minimum.
