No Disrespect to ED but the man is sponsered Mega Mega Mega bucks (talked to a guy who knows him very very very well). If ed wants he does not have to do anything to build his robots. All he has to do is do up a cad and get it all custom machined and it dont cost him a penny (sponsers pay it all)

Anyone who is skilled on CAD and has a sponser could build/buy (change where appropriate) a robot much easier than most of us bodgers.
