Copying the humble honeybee's foraging methods could give robots better 3D vision, researchers say. Robot explorers could identify points of interest by mimicking the way bees alert others of promising foraging spots. Explorer bees report the location of a new food source, like an inviting flowerbed, by dancing on a special area of honeycomb when they return to the hive (see How vibes from dancing honeybees create a buzz on the dance floor). A new type of stereoscopic computer vision system takes inspiration from this trick. It was developed by Gustavo Olague and Cesar Puente, from the Center for Scientific...
