Did you know?
Ever spin a top? A top is a flywheel, a spinning disc that stores energy. Once a flywheel gets going, the stored energy keeps the spin going for a long time. The Robo Wheel is a flywheel. Like a top or a tire rolling down a hill, once it gets rolling, it keeps going until a force interferes with its spin.
