8 Dynamixel AX-12A servos to give your robot arm a boost

The PhantomX Reactor arm also provides you with an excellent opportunity to discover the Dynamixel AX-12A servo motor: you’ll need 8 of these (included in the kit) to get your robot arm working. There are 2 in the arm’s first joint (shoulder) and 2 others at the elbow for great freedom of movement and more power.

In addition to offering an excellent range of motion, this type of servo also allows you to control the position, load, voltage level, internal temperature and compliance settings, all extremely easily using just your ArbotiX microcontroller!
