iMobot is designed by University of California, Davis alumnus Graham Ryland and professor of mechanical and aerospace engineering Harry Cheng. It can help engineering to use it as pre-built modules in robotic machine.
A novel modular robot design that incorporates four controllable degrees of freedom made up of two outer sections, and rotating faceplates at the ends of each outer section. The outer faceplates can rotate continuously, which enables individual modules to turn while crawling, or 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. more at
