Do you know the song “Summ, summ, summ, Bienchen summ herum”? Raúl Rojas laughs. Rojas, a professor of computer science at Freie Universität, doesn’t recognize the children’s song at first. But knowing a song isn’t all that important compared to his knowledge about the language bees use with each other, most of which he learned from neurobiology professor Randolf Menzel. That knowledge forms the basis for an unusual project between the two scientists: Working with their teams, the biologist and the computer scientist aim to show that bees use a dance to communicate with each other when looking for food. To provide evidence, the scientists have developed a robot bee that they hope will let them put in a word inside the hive – showing, under controlled conditions, which signals are important during these insects’ movement rituals.
