The emergence of the synchronization in a complex networks of chaotic or phase oscillators is of great interest in multidisciplinary research. One trend of this research is related to mobile autonomous agents that interact mutually in order to accomplish collaborative tasks. These agents may be modeled using active networks of oscillators whose collective behaviors might present chaotic dynamics and their synchronous states are associated to possible formation groups. This research project intend to understand the relations between the agents connections topology and the resulting system behavior, also taking in consideration the influence of propagation delays and the emergence of synchronization groups. The results will be assessed with mobile robots, aiming for applications with groups of satellites in formation motion. (AU)
