This paper complements the results and analysis shown in current studies on the evolution of signalling and cooperation. It describes operational aspects of the evolved behaviour of a group of robots equipped with a different set of sensors, that navigates towards a target in a walled arena. In particular, analysis of the sound signalling behaviour shows that the robots employ the sound to remain close to each other at a safe distance with respect to the risk of collisions. Spatial discrimination of the sound sources is achieved by exploiting a rotational movement which amplifies intensity differences between the two sound sensors.
