I think this is a really good story. It keeps you entertained the whole way through. Because it's from Bobby's point of view it helps readers to learn more about life where and when Bobby is. I esspecially like the fact you took time to emphasize the movie, showing with absolutely no doubt this story is placed in the future.
The idea about robots learning emotions but not wanting to destroy humanity is a wonderful change to ususal storylines.
Overall this is a really great story, HOWEVER not the most memerable of storylines. That said, it seemed a little emotionless for me BUT any more emotion would have killed the storyline since it IS about robots, Bobby in perticular.
