A bartender watches as an Infinium-Serve Flying Robot takes off with an order at a restaurant during a pilot demonstration for the media in Singapore February 5, 2015. The Unmanned Aerial Vehicle (UAV), or drone, a working model designed by firm Infinium Robotics that specializes in UAV solutions, aims to free up restaurant staff to do "higher value tasks" by accurately delivering orders up to 500 grams to tables within the premise by means of anti-collision algorithms, according to Chief Executive Officer Woon Junyang. The programme is currently undergoing testing for its launch at the end of the year. REUTERS/Edgar Su (SINGAPORE - Tags: BUSINESS FOOD SOCIETY SCIENCE TECHNOLOGY TPX IMAGES OF THE DAY)
