In the afternoon of March 10, 2010, at the Hall of Department of Control Science and Engineering, Zhejiang University Yuquan Campus, an intelligent service robot "Hai Bao" was designed to hold a "press conference", and fluently answer questions to audiences one after another. Over a month late, 37 robots "Hai Bao" will debut at the 2010 Shanghai World Expo and provide services for visitors at the Expo venue and two major international airports in Shanghai.
