An American cyclist has created a cycling robot that gives him extra pedal power. "Joules", a human-proportioned robot, helps power the cycle along with an electric motor.

More whimsical than just going down the electric bike route, Joules, complete with cycle helmet (safety first, kids) was built from "an array of nuts, bolts, shafts and chains" over a 4-month period.

Apart from exercising rusty "shop" skills, the engineer behind the design says he made the creation because:

"Very few kids get excited by actually building something. I wanted to show local kids that having ideas and building them is fun! We need lots of kids to believe that, I think".
