“MiP was designed in a collaboration between Wowwee and the Coordinated Robotics Lab at the University of California, San Diego. It balances just like the Segway, using the mobile inverted pendulum principle (hence its name) – in a nutshell, this means that the bottom of the robot is constantly moving back and forth, in order to keep the weight of the top section centered above it.”
