Ant leading other ant to new nest, known as tandem running. The team built the robot to mimic the behaviour of rock ants that use one-to-one tuition, in which an ant that has discovered a much better new nest can teach the route there to another individual. The findings, published in the Journal of Experimental Biology, confirm that most of the important elements of teaching in these ants are now understood because the teaching ant can be replaced by a machine. Key to this process of teaching is tandem running where one ant literally leads another ant quite slowly along a route to the new nest. The pupil ant learns the route sufficiently well that it can find its own way back home and then lead a tandem-run with another ant to the new nest, and so on.

Scientists from the University of Bristol have developed a small robot to teach ants and in turn, the ants were able to teach others in a unique experiment with the potential to replace one day the way humans are taught. The team built the robot to emulate the behavior of rock ants that use one-to-one tuition. Whenever an ant finds a much better nest, it teaches the route to another and the transfer of knowledge goes on to the entire ant community. Here researchers replaced the teacher ant with a small robot and taught an ant in tandem running along to a new nest. The pupil ant was not only able to learn the route but also found its way back home and then led a tandem run with another ant to the new nest.

Prof Nigel Franks of Bristol's School of Biological Sciences said: "Teaching is so important in our own lives that we spend a great deal of time either instructing others or being taught ourselves. This should cause us to wonder whether teaching actually occurs among non-human animals. And, in fact, the first case in which teaching was demonstrated rigorously in any other animal was in an ant."
