A pedestrian looks at a robot that specialises in greeting people outside 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 (4.27-5.25 ft), 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. The sign the robot is holding reads, «Robot Restaurant, go downstairs and have dinner.» REUTERS/Sheng Li (CHINA — Tags: SOCIETY SCIENCE TECHNOLOGY)
