The Kaputt.R Demolition Robot designed by Tony Weichselbraun looks like a dangerous force to be reckoned with. This sucker packs a punch as far as destruction is concerned.
The Kaputt.R Demolition Robot stands on four electric tracks (which look like mini-tank wheels) that give it great balance when operating the two massive extending arms. The arms provide a wide range of motion and can be fitted with a buzzsaw, plow or the trademark Powergun.
The Powergun uses propane gas (pollution reduction) to shoot linear fire streams at the walls of a structure in order to weaken it and make the demolition much easier. I would stay out of its way!
