In this talk we will examine to which extent the use of discrete dynamical systems, mainly Cellular Automata (CA) and Chip Firing Games (CFG), can help us understanding the robustness of biological phenomena. We will first examine how robustness can be defined on some toy-models and show results of numerical experiments. We will then use the results obtained on the toy-models to model two biological phenomena that exhibit robustness: - the aggregation of the amiboe DictyoStelium Discoidum. - the shape apparition in tissues. Finally, we will examine how these results could be translated to build robust processes in robotics.
