RoboRails: The Robot Monorail music Push the pink bumpy ballExplore the future of transportation with RoboRails! This compact robot balances on a single wheel and glides along a monorail track thanks to its fast moving internal gyroscope and monowheel. A clever design uses ball bearings as the weights of the gimbal, which is nearly frictionless as it spins. Youll be amazed at how steady this robot is on the track!
