Honda developed the U3-X with technology originally developed forASIMO the bipedal human robot project. Honda states that the "U" stands for unicycle and for universal.[5] It weighs 10 kg (22 lb) and travels at 6 km/h (3.7 mph), a similar speed to theToyota Winglet. Honda U3-X is a compact experimental device that fits comfortably between the rider's legs, to provide free movement in all directions just as in human walking - forward, backward, side-to-side, and diagonally.[6] It uses HondaOmni-Traction (HOT) drive system to permit it to move in any lateral direction. The system uses multiple small diameter motorised wheels connected inline to form one large diameter wheel. Rotating the large diameter wheel moves the U3-X forward and backward, while rotating the small diameter wheels moves it side-to-side. Combining these movements causes the U3-X to move diagonally.
It has not been announced yet whether the vehicle will be offered for public sale. The price is not announced yet.
