Yamaha Motobot autonomous motorcycle rider taunts Rossi

No one can accuse Yamaha of dreaming small with its Motobot project on display at the Tokyo Motor Show.

The work's incredibly lofty goal is to build an autonomous, motorcycle-riding robot capable of beating MotoGP superstar Valentino Rossi around a track. Highly skilled human riders already have a serious challenge against Rossi during races, so there's definitely a lot work ahead for this machine.
