Stop Motion Robots

Hi eveyone,

I do stop motion animation and I've always had in the back of my mind if it was posible to make a robot out of a stop motion puppet puppet and do some of the more intricate "stunts" with a robot vs by hand. As you can see from the images included, the joints on this are pretty small. I was wondering if anyone has any ideas of hardware that might work for this sort of thing or if alternatively a separate mechanism that would drive the puppet would be the prefered alternative. Out of the box thinking encouraged!!! Any info--specially with pictures included--would be appreciated.

Best regards,

Steven
