In order to increase stability on the Uni-Cub, Honda has added a smaller wheel behind the drive wheel. The Uni-Cub has also been given arm rests for added comfort, and according to Honda, the Uni-Cub can achieve a top speed of 10kmph, but unfortunately the prototype device only has a battery life of one hour.
Once again, much like the U3-X, the Uni-Cub remains a prototype for now with no plans for commercialization, although should it actually be put into production, Honda foresees the Uni-Cub being used in places like shopping malls and exhibition halls to get from one end to the other quickly.
