Robotic Beer Launching Fridge

This robotic beer launching fridge is one of those ultimate projects that you are guaranteed to see posted all over the internet today. Robots, beer, the possibility of maiming innocent bystanders… what’s not to love? I’d be lying if I said my mechanical engineering friends and I weren’t contemplating this at many points during college. Kudos to John W. Cornwell of Duke for actually pulling it off. The mini-fridge has three servos: one to elevate beer from the 10 can magazine, one to rotate the turntable, and one for cocking. Spring power is used to catapult the beer across the room. The brains of the system is an ATMega8535 and 3 intelligent H-bridges. It’s controlled by an adapted key-less entry system. It looks like they’ve wisely placed it pointing away from the tv, but I don’t know if referring to your apartment as the “man-pit” is nearly as smart. Check out some of John’s other projects: the Mentos booby-trap and the touch activated paintball gun.
