Scientists around the world are studying animal behavior in a new way by using robo-animals.Robo-animals are robots that look, amell, and act like real animals. For example, researchers in Brussels created a robotic cockroach to observe how cockroach move around in darkness,Students and professors at the university of Amherst in Massachusetts are using a robo-squirrel to lean about the survival instincts of squirrels. Scientists in Indiana have created a robotic lizard that help them study the mating rituals of lizards. Robo-animals are giving scientists a unique way to lean more about how animals work in group, court, avoid danger, and communicate with each other.
