Roland Piquepaille writes "In 'The frog robot condom,' The Scientist invites us to follow Peter Narins, a professor at the University of California, Los Angeles (UCLA). He has already been on 42 field expeditions, tracking the vocal behavior of animals in their natural habitats. But his most interesting research work has been done with frogs. Since 2001, in places such as China, French Guiana or Puerto Rico, he has been using robotic frogs housing a speaker and an air pump. But the air pump, used to call or to ask other frogs to leave, inflates and deflates the robotic frog's throat sac, made from a condom. Next year, Narins will go to Brunei to study another kind of frog. But he will use enhanced versions of his robots which will be equipped with several motors. But read more about Narins various experiments with robotic frogs."
