I, for one, welcome our new Makerbot overlords.

I'm a huge fan of the LeFabShop robot, but I had one problem with it, aside from the lack of heavy artillery. Too much of the weight is in the back, so he can't stand up without falling back into a sitting position (most of the time.)

I present to you my American version of the Maker Faire bot. The weight of the rocket moves his center of gravity forward. He also has a hollowed out compartment with opening and closing doors in his back, which reduces weight there. These modifications allow him to stand up straight, and vanquish his enemies, every time.
