Check out this awesome video of a segway like vehicle from Toyota – they call it the Winglet. The video defenitely looks awesome. The controls seem to be very easy and intuitive – except the brakes. I could not figure out how they stop the thing. I am sure there must be some way. The segway guys invented the accelerometer based balance stuff. I think Toyota has a cool implementation of it. Check it out below. It is a pretty small video.
