The Magician from DAGU is a low cost Arduino compatible controller designed especially for beginners wanting to build a small robot. A robot can be built by simply plugging in a few motors, servos and sensors. Using the Arduino IDE and supplied library, relatively little code is required to make a functional robot.
The Spider robot controllers were designed for robots requiring a large numbers of servos such as humanoid and hexapod style robots. Using an ATmega 2560 CPU this controller is fully compatible with the Arduino Mega (2560) and can controll up to 48 servos
