Simlicants: The ulimate sim robot

I do not want robots that look human for that would take away the reason of the life state. If I can create a yes, why would I create a robot?
Also, I know that if the producers chose androids, they would take advantage of the charge for something we already have in the game, the CAS. And they would not make a life-state as good as it should. I prefer metal robots myself.
