How many motors do you need to make a robot which can move in 2 dimensions? Most need 2, either left-right differential like a tank, or one for going forward and one for steering, like cars. There are experiments to achieve steerable robots using just one actuator, notable ones are the 1STAR from UC Berkeley (which has 6 legs, the middle legs are elastic) and the Monospinner from ETH Zurich (which can even fly), but they require complex and delicate mechanisms and control systems.Introducing Monobot, the single servo robot.
