An anonymous reader writes "One group of Australian researchers have managed to teach robots to do something that, until now, was the reserve of humans and a few other animals: they've taught them how to invent and use spoken language. The robots, called LingoDroids, are introduced to each other. In order to share information, they need to communicate. Since they don't share a common language, they do the next best thing: they make one up. The LingoDroids invent words to describe areas on their maps, speak the word aloud to the other robot, and then find a way to connect the word and the place, the same way a human would point to themselves and speak their name to someone who doesn't speak their language."
