The robot can be controled by a CPU or remote control, so he doesn´t need a head or anything like it, but it need those holes, because there are cameras inside it that are usesd to give visual data to him. ( This is what I imagined when i modeled it, so i don't thing i'm going to give up these holes. Maybe if I make an Head for it, but i didn´t wanted this already-used-to-many-times design, so I tried to make something diferent, but thanks for the comment !

( sorry about my ' Engrish' ) 8 -)
