Smart robot that hunts for its own "food":
Meet Energetically Autonomous Tactical Robot (
). EATR, according to researchers gets its energy by foraging, or "engaging in biologically-inspired, organism-like, energy-harvesting behavior which is the equivalent of eating. It can find, ingest and extract energy from biomass in the environment as well as use conventional and alternative fuels (such as gasoline, heavy fuel, kerosene, diesel, propane, coal, cooking oil and solar) when suitable." The purpose of EATR is to develop and demonstrate an autonomous robotic platform able to perform long-range, long-endurance missions without the need for manual or conventional re-fueling - in other words it needs to "eat."
