I know that it is not literally a Vex robot, but I thought this was pretty funny. I was just looking around the Internet when I found this picture of the Sony QRIO robot. Apparently, it can do almost anything, including tossing raquetballs. And it's just the right height for the Vex center goal!
All that is left is for them to take this and built it out of Vex parts!
