Self-Balancing Mecanum Wheel Bike
Engineer James Bruton adds to his collection of unusual vehicles with the creation of a single-seater that rolls on four 3D-printed mechanum wheels. The not-quite-a-bike uses motors and an inertial measurement unit to remain balanced. By changing the speed and direction of each wheel, it can move forward, backward, sideways, and spin around on a dime. Its agility is quite impressive.
