Researchers from the universities of Texas and Tennessee used Raspberry Pi computers to track unseen drones with sound.
The DroneChase implementation involves programming the Pi to enclose a detected drone within a red box, using audio to zero in on its location and keep tabs on it even when it is hidden by intervening objects.
A three-dimensionally-printed housing contains the tracker, which could be mounted on a vehicle.
The researchers trained the artificial intelligence model to locate a drone if it is within the camera's visual scope.
DroneChase operates as part of a custom-designed system that uses six microphones to triangulate the drone's position.
