Humans might not be the fastest things on two wheels before long. Yamaha has unveiled Motobot, a robot designed to ride superbikes much like you would -- it even has to twist the throttle to get moving. This initial version travels slowly and needs training wheels to avoid tipping over in a turn, so it's not about to compete on the MotoGP circuit just yet. However, Yamaha ultimately hopes to get Motobot blasting along at more than 120MPH on a race track. It goes so far as to put racing legend Valentino Rossi on notice, as you'll see in the promo video below.
