Dynamixel MX-28T. Dynamixel smart actuators have been used by every major university, research lab, military & government research lab, and robotic competition worldwide. The casing of each servo is built specifically with robotics in mind, providing easy to use mounting rails and a comprehensive bracket system available for building robotic limbs. TTL and RS-485 serial communication allows for daisy-chainable bus connections at up to 1-3mbps.
MX-series is a new concept of DYNAMIXEL with advanced functions, such as precise control, PID control, 360 degree of position control, and high speed communication.

The servo has a fully integrated DC Motor + Reduction Gearhead + Controller + Driver + Network in one DC servo module.
