A robot petting zoo at Maker Faire Bay Area 2012? What could possibly go wrong? Nothing, actually. The kids loved it -- only the robots cowered in fear (of being sat on). MakerBot spent eight weeks building four different species of robots using its Replicator 3D printer -- wheelies (robot chickens), bubble bots, button bots and bumper bots. Judging by the crowds the event was a complete success. We caught up with Michael Curry of MakerBot who told us how the robot petting zoo came to be and walked us through some of the robot specifics -- designs that should appear on the company's Thingiverse website by the end of the week. Next stop: Maker Faire New York. Are you ready for an invasion of cute robots? Find out in our hands-on video after the break.
