Defense Advanced Research Projects Agency (DARPA) is the United States Department of Defense’s agency responsible for the development of emerging technologies to be possibly used for military purposes. The agency was created on February 7, 1958. It was originally known as the Advanced Research Projects Agency (ARPA) by then-President Dwight Eisenhower after the Soviet Union launched their Sputnik 1 in 1957.

Energetically Autonomous Tactical Robot (EATR) was a concept developed between 2003 and 2009 as part of the DARPA military projects. The concept became Robotic Technology Inc. (RTI) and Cyclone Power Technologies Inc’s project, aiming to develop a robotic vehicle that could search and use plant biomass to self-fuel, thus, having an infinite source of energy and operating indefinitely.
