I just released a new video tutorial showing how to use some RobotGeek modules with the DynamixShiled and an Arduino Due. The DynamixShield is a product I am building that works with the Due to give you the ability to control Dynamixel smart servos, and it has a ton of Grove and RobotGeek connectors. Grove and RobotGeek are frameworks for robotics that allow you to purchase commercial modules and plug them in with a single cable. I have a Kickstarter going on for it now. Please take a look at it.
