Sophisticated Servos

The DX-117 Dynamixel is more than just a digital servo, it's a highly sophisticated robotic component.  
Each servo has the ability to track its
speed, temperature, shaft position, voltage, and load.  As if
this weren't enough, the control algorithm used to maintain shaft position can be adjusted individually for
each servo,
allowing you to control the speed and strength of the motor's response.  All of the
sensor management and position control is handled by the
servo's built-in microcontroller.  This
distributed approach leaves your main controller free to perform other functions.

Note:
This actuator is controlled by RS485 serial communication.
