A six-legged robotic sheep, with grass-mowing teeth and GPS navigation: gotta be inspired by Philip K. Dick, right? Yes, it is: Mower was created by Osman Khan, a visiting professor at Carnegie Mellon's School of Art, and is on display as part of the Bigbots exhibit at the Robot 250 festival. Mower roams around using GPS to place itself on grassy areas, has collision avoidance sensors and makes the most amusing array of sounds as it clatters about. Clearly intended to be a humorous reference to robotic lawnmowers and the "green" method of using real sheep to do it, he's on display at Phipps Conservatory & Botanical Gardens. Robot 250 runs until July 28th. [Robot250 via BotJunkie]
