Around the holidays you can expect Christmas trees, twinkle lights, cocoa, and, now, robots? They're part of the Christmas lineup at Bloomingdale's flagship 59th street store.

The department store is mainly incorporating robots into window displays and decor, but serving coffee they show how robots will "enhance the future retail experience," according to Bloomingdale's.

Other retailers have also tried to incorporate robots into their physical stores. Pepper, the humanoid robot created by Japanese company SoftBank, is possibly the most recognizable. SoftBank recommends using Pepper as a greeter, brand ambassador, survey conductor, and more.
