Japanese company Honda has demonstrated its U3-X Personal Mobility Prototype in New York. The device has a slight resemblance to a unicycle but is probably best explained as a one-wheeled, sitting version of the Segway. It allows a user to drive in all directions by shifting their body weight forward, backward or to either side.
The U3-X's stabilization algorithms are derived from Honda's research with the ASIMO robot. The device also uses a specifically developed one-wheel, omni-directional driving wheel system to allow simultaneous forward and sideways movement.
While the maximum speed of the U3-X is a mere 6 kilometers per hour, less than a third of the Segway's, it is significantly smaller and lighter, weighing only about 10 kg (22 lbs). For now, no information on pricing and availability has been released.
