Isn't war gruesome enough without a robot scavenging the battlefield, ingesting corpses for fuel? An experimental robot produced by a military contractor can consume just about anything to keep running. Dubbed the "Energetically Autonomous Tactical Robot" (EATR), the robot could theoretically run for years on fuel it consumes in the field. Fox News reports the robot could be used to build "a transport, an ambulance, a communications center, even a mobile gunship." The company that developed the robot describes its ability to "forage," rather than presenting it as a Cyberdyne-worthy nightmare.
