If you've followed the blog for a while you'll know that I have a thing for robots, and I'm a pretty big Google fanboy but that's another story. Thanks to Gizmodo for bringing my attention to Joules. According to Greyhair100's Youtube page "Joules the Robot sits on the back of a tandem bicycle and does the pedaling for both of us"
Did you recognize the song in the background? Robots and Daisy... perhaps Joules is a descendant of Hal 9000 or vice versa?
