With U3-X Honda rethinks the concept of personal mobility, providing the rider with freedom of movement in any direction – forward, backward, sideways and diagonally – by simply leaning slightly in the desired direction. The lightweight and compact one-wheeled device also features a foldable seat and retractable footrests. A lithium-ion battery pack provides power for up to one-hour of use and can be recharged by plugging in to a conventional household or office 120-volt power outlet.
Weighing roughly 22 pounds, U3-X uses an advanced Honda proprietary balance-control system which derives from its research into human walking dynamics for the development of the ASIMO bi-pedal humanoid robot. To realize full freedom of movement in all directions, the U3-X also employs the world’s first omni-directional driving wheel system (Honda Omni Traction Drive System) which utilizes a series of concentrically mounted wheels – a larger, forward and backward moving inner wheel and a series of smaller sideways moving outer wheels. Diagonal motion is achieved when both forward and sideways moving wheels operate in tandem.
