From Cozmo to Vector: How Anki Designs Robots With Emotional Intelligence?
From Design News:
The little robot on my desk knows my name and recognizes my face. He tells me when he needs maintenance. He has three cubes that he loves to stack, knock over, and play with. He'll also tell me when he's bored and wants to play a game. When he wins, he'll dance around. And if I beat him too many times, he'll get sad or throw a temper tantrum.
(An aside: If Anki can do it @Ankita can do better!)
