You need 10 onions, a mouse's brain, and a LOT of distilled water(it helps electrical impulses from the brain not influence the servos in a bad way)
Mash up 5 onions in a tray, and put the mouse brain in them, mash up the other 5 and mix with distilled water, put those OVER the brain, now, the onions with water go on top, and the normal ones on the bottom.
Next time you turn it on, it should work.
You must spend hours of programming.
And what do you mean by personality?
