Look, no hands. Scooting about on what looks like a floating car seat is no sweat for anyone with Honda’s new hands-free robotics technology. Swaying your body from side to side is all you need to do to turn, rotate full circle and zip around on the Uni-Cub. The Uni-Cub has one main wheel, while a tiny wheel at the back helps for circular moves. Reporters got a test ride on the machine Tuesday. It takes some getting used to but responds smoothly and quietly. Lean forward to go straight, to the left to go left. If all fails to stop, just put your foot down. Uni-Cub will be on display at a Tokyo science museum. There are no plans yet for a commercial product.
