Special Comments:
These were the oddest things.  Basically the majority of the body is an air tank.  It has a small pneumatic valve and piston assembly that motorizes the entire unit.  The wheels stretch and contract in a scissors motion that propels the Stoomdorm.  At the time these came out, there was another one that was different, but I can't remember what the other one was called or what it looked like even.  It was a long time ago!

I have received some flak about these not really being robots.  I guess they're right.  I still like them, and well... it is my page!
