Hemispherical Gimbaled Wheel or HOG Wheel Drive System
A hemispherical omnidirectional gimbaled wheel, or HOG wheel is nothing more than a black rubber hemisphere that rotates like a spinning top, with servos that can tilt it left and right and forwards and backwards.
Powered by this simple drive system, the robot that it's attached to can scoot around the floor in ways that I would have to characterize as "alarmingly fast."
Have a look at just what this thing is capable of. Its creator, Curtis Boirum, a grad student at Bradley University, in Peoria, Ill., demoed it at the 2011 RoboGames symposium:
