Many researchers and scientists all over the world are creating humanoid robots to help with the work but one country has gone up and beyond all the others and has created robots that can vacuum office corridors, spoon-feeding the elderly, work in factories and be used as receptionists. For example even though robots are no where close to having the same "emotional complexity" as humans, students at a university lab at Tokyo are creating a robot that shows the basic six expressions: anger, fear, sadness, happiness, surprise and disgust. when you say a word like war the robot shows a expression of disgust and when you say love, the robot starts to smile. Scientists hope to soon have a robot in every home and a scientist named Hiroshi Ishiguro even hopes there are so many robots that some people might even ask you, "are you a human or are you a robot?!"
