Character Design (Developed)

I have decided to stick with my Robot Ideas. I will be developing him to get the final Design. Robot is obviously an artificial character, who supposed to have no emotions and moves as the human requests them to. I wanted to link Robot's miserable life to the animation, one of my idea is that Robot is all alone and wants to be loved. He supposed to not have any emotions but he is the one of special Robot that can create emotions. Again, I am going to stick with the simple designs because I think simple character would be easier to animate.
