Honda's UNI-CUB mobility device is the butt of ASIMO's jokes
 

Our humanoid friend ASIMO had better start counting his blessings. If fate had dealt him another hand, he could have ended up as the behind-wearing UNI-CUB. Honda's latest personal mobility device appears to be a robotic stool with an omnidirectional wheel (dubbed the Honda Omni Traction Drive System, no less). You control speed and direction of the UBI-CUB by shifting your weight in the saddle, and the unit is designed to keep you at eye-level with non chair-riding pedestrians. Obviously this is no all-terrain vehicle, but it does claim to be able to handle gradients, has a top speed of six km/h and a range just under four miles. Which should be plenty for the National Museum of Engineering in Japan where these butt-supporting bots will be demonstrated in June.
