I saw one not so long ago at university. It was pretty amazing - about 2m tall, lots of rotary axis' with servos and very stealthy. The guy operating it let me have a go, just pressing the jog buttons. Fun :) ! Good to watch when it just moves in a straight line since none of the axis are linear. I think it was 6 axis iirc.
