8. Honda U3-X
Honda is also no stranger to omni-directional wheels – the company has already released Honda U3- X, a one-wheeled vehicle that fully incorporates the first omni-directional driving wheel system in the world. This personal vehicle provides absolute freedom of movement and a smooth, although a relatively slow, ride with Honda’s Asimo balance control technology. You can make this unique device move wherever you want it to – forward, backward, left, right, laterally, and diagonally. It’s like walking, only faster and more fun! Honda U3-X’s one large-diameter wheel consists of smaller motor-controlled wheels that allow the mechanism moving side-to- side. The next wheel design is even more mind-boggling!
