“The U.S. Marine Corps showed off LS3—nicknamed Cujo—on Saturday at Hawaii’s Kahuku Training Area during the Advanced Warfighting Experiment portion of RIMPAC 2014, a biennial multinational maritime exercise, according to a statement. Cujo can traverse rocky terrain with its lifelike gallup, and is programmed to follow an operator and detect surrounding objects with its swiveling head of sensors. Marines demonstrated Cujo’s tricks by using it to conduct resupply missions across terrain difficult to traverse by normal vehicles.”
