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/
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.
