Bat Noses (image) Virginia Tech Caption These images are of the noseleaf of a typical horseshoe bat species (left) vs. that of Bourret's horseshoe bat, the Rhinolophus paradoxolophus (right). Computer modeling indicates the extreme nose is used to create a highly focused sonar beam. One of the researchers is Rolf Mueller, an associate professor with the Virginia Tech mechanical engineering department, who directs the Bio-inspired Technology Laboratory. His research includes biosonar-inspired autonomous robots and statistical signal processing methods in natural outdoor environments.
