Dynamixel AX-12/AX-12+/AX-12A is a smart servo with up to 15kgf.cm torque and has networking capabilities through UART TTL half duplex multidrop interface. Dynamixel AX-12/AX-12+/AX-12A consists of reduction gearprecision DC Motor, and control circuits in one package. AX-12+ is the revision version of AX-12 with improvement on circuit design, material, and wheel gear. AX-12A is the newest version of AX-12+ with the same capabilities. The only difference between the two is on its design. At this moment, the only available version is AX-12A.
