China has joined the ranks of robot-run eateries with its Robot Restaurant in Harbin. We are talking full-scale serving here, from the Wall-E-esque greeter to the chefs to the servers. All told there are 20 of them um, employed. Each server bot follows a track on the floor and each has sensors for avoiding obstacles as well as a smattering of Chinese for conversation. Opened since June 2012, the robots were designed by the Harbin Haohai Robot Company with price tags ranging from $31,500 - $47,000 apiece. Not a bad deal since they will never require lunch breaks or tips.
