Drones can determine the shape of a room by listening to echos from the walls, according to mathematicians from Purdue University and Technische Universitat Munchen. Mireille Boutin (Perdue) and Gregor Kemper (Munich), with few exceptions, can theoretically get the shape of a room providing the drone is carrying four microphones that all hear echos from a ...
