I think you have in mind a robot in the real world. I do believe that the real AI would have to be embodied, have body which can use to sense and understand the things by itself (example: you can teach an AI to recognize a chair but you can not teach that it can use a rock as a chair unless it goes and sits there). Emotions are one of the things you might need to create a similar human intelligence, but there are also more things you would need (abstract representation, abstract reasoning, imagination, self representation, etc). Take a look to this research about machine conciousness: http://www.conscious-robots.com/consscale/ http://www.conscious-robots.com/consscale/ Unfortunately the research are more focused in the AI that leads to better algorithms as better image recognition. All the part about a real robot intelligence which can feel is mostly missing and few people work on this.
