VIRGINIA BEACH, Va. (Oct. 4, 2016) An unmanned rigid-hull inflatable boat equipped with electro-optical and infrared (EO/IR) sensors operates autonomously during an Office of Naval Research (ONR)-sponsored demonstration of swarmboat technology held at Joint Expeditionary Base Little Creek-Fort Story. During the demonstration four boats, using an ONR-sponsored system called CARACaS (Control Architecture for Robotic Agent Command Sensing), operated autonomously during various scenarios designed to identify, trail or track a target of interest.
