Robots with sensors are quickly replacing the eyes and ears of soldiers on the battlefield. The Army Research Laboratory (ARL) has developed a robot-based acoustic detection system that will detect an impulsive noise event and activate a pan-tilt to orient a visible and infrared camera toward it. Onboard image processing can then track the target and/or transmit the imagery. Such a vehicle can provide reconnaissance, surveillance, and target acquisition. The primary robotic platforms contain 16-in. diameter, eight-element acoustic arrays. Additionally, a 9-in. array is being developed. The robots have been tested in both urban and open terrain. Detection algorithms for speech and vehicle detection/tracking are being developed. The collaboration between two robots, both with known positions and orientations, can provide useful triangulation information for more precise localization of the acoustic events. These robots can be mobile sensor nodes in a larger, more expansive, sensor network that may include stationary ground sensors, UAVs, and other command and control assets.
