You can use the Smart Servo Controller for Arduino to control AX series Dynamixel Servos.
The Pololu Micro Maestro 6-channel USB Servo Controller is intended to control standard RC servos and won’t work with smart servos as Dynamixel or Herkulex servos.
As to control Herkulex servos, you can use directly the Arduino board (without a shield). Here is the Arduino library to use control Herkulex servos with Arduino.
You won’t need the Interface Manager to control Herkulex servos with Arduino.
