Robots deliver dishes to customers at a Robot Restaurant in Harbin, Heilongjiang province, China. Opened in June 2012, the restaurant has gained fame in using 20 robots, which range in heights of 1.3-1.6 metres, to cook meals and deliver dishes. They can work continuously for five hours after a two-hour charge, and are able to display over 10 expressions on their faces and say basic welcoming sentences to customers, media reported.
