Adafruit 16 Servo Shield
You want to make a cool Arduino robot with ARC? Maybe a hexapod walker, or a piece of art with a lot of moving parts. This is Adafruit's popular PWM/Servo Breakout that works with any Arduino that uses shields: Uno, Leo, Mega, or ADK.
We recommend using the Uno, because it is compact and combined with this shield, provides a ton of I/O. If you require more than 16 servos, we also recommend the EZ-Robot EZ-B v4.
The UNO can be programmed with the EZB firmware for a variety of capabilities when connected to ARC. The tutorial to program the EZB firmware can be found HERE. This hardware was added to ARC in this beta release and newer.
