See more at http://www.barobo.com. iMobot is an Intelligent Modular Robot designed for college and university teaching and research. It has four controllable degrees of freedom. The faceplates can turn continuously so an individual module is able to drive as though with wheels. This significantly increases the mobility of each module, allowing it to traverse a wide variety of terrain without an overcomplicated physical shape.
