The plans for that robot are open source, and most of the parts are 3D printed. It would take me a LONG time to print all of those parts, and the cost of the electronics might be a shock (must be many dozen servos in there!). And of course I'd want to do a little redesign on the head, to make it look a bit like

Interesting idea. Wonder if anyone is throwing out a segway in need of repair?
