I think this may tell us more about humans than about robots. Notice how the article mentions some children at the London Science Museum enjoy cuddling/"babying" the robot, others want to try and scare the robot. Maybe trying to simulate emotions in robots will give us insight into human emotions and perhaps open up ways to encourage "the better angels of our nature".
