A 'waiter' robot serves a customer

A robot that specialises in delivering food serves a customer with French fries at a Robot Restaurant in Harbin, Heilongjiang province January 12, 2013. Opened in June 2012, the restaurant has gained fame in using a total of 20 robots, which range in heights of 1.3 – 1.6 metres, to cook meals and deliver dishes. The robots 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, local media reported.
