Energetically Autonomous Tactical Robot — that's right, "EATR" —

"EATR" — THE LINK

Quote :

A Maryland company under contract to the Pentagon is working on a steam-powered robot that would fuel itself by gobbling up whatever organic material it can find — grass, wood, old furniture, even dead bodies. ...

...Upon the EATR platform, the Pentagon could build all sorts of things — a transport, an ambulance, a communications center, even a mobile gunship.

Some sort of horrific irony going on there.

Very Terminator sounding. For some reason that reminded me of this.
