Robots are ringing in the holidays at Bloomingdale's New York store. Three of the 12 windows at the 59th street location feature robots in an bid to show how the retail company will'enhance the future retail experience'. Customers watch robots work together to create an'Autonomous Christmas Tree Decorating' display, play instruments in a full orchestra and sing'Christmas Carol Karaoke'. Bloomingdale's is known for its stunning and whimsical holiday displays, but this year it has teamed up with ABB robots and robot animator Andy Flessas to create a unique display to showcase how retailers can enhance the future retail experience. Two floor-mounted and two ceiling-mounted IRB 120 robots co-ordinate their movements to pass 20 gold ornaments to each other, placing them on the branches, before stripping the tree and starting the 30-minute process again.
