LadyBugBot
Isotope, of Let's Make Robots, built this amazing fridge-climbing LadyBugBot. Using a CD as a base, and sporting a papier-mâché cover, it uses two motors with wheels to drive around, except there's a catch: instead of moving across the floor, it uses a set of magnets to stick to his fridge, and drives up and down instead of forwards and backwards. He also designed a combination bump/depth sensor, to sense if the robot is in danger of running into something or off the edge of the fridge.
