help, I'm stumped! Pictures would be awesome. Thanks!!!

Have you seen "Rollie Pollie Ollie"? I am not sure of the spelling but it used to be a TV show http://disney.go.com/disneychannel/playhouse/rpo/rpo_home.html

They are kinda like kid robots. Very cute though.

Another thing that came to mind it "The Robots Movie"

Maybe those will help?

Sorry no pics...just popped in my head.

Make a robot and give it a diaper and a rattle?

I just looked a Toys R Us online and typed in robot. They have a rug that has several robots on it. One of those might give you some inspiration.
