The Micro Aerial Vehicle (MAV) represents a strategic and industrial goal. The challenge is truly technical, as the needs are very specific in terms of mission and efficiency. The aerospace French agency (Onera ) has launched an internal program on that purpose including many research topics, essential to understand how to reach the goals. Thus, aerodynamic (generally unsteady with low Reynolds number), structural dynamics, propulsion, actuation, control,.. are being studied in this field. On a structural and mechanical actuation point of view, presently our main interest, the problem is already very large. So before analyzing and formulating, we found not so meaningless to look how nature proceeds and to start a design study with a "biologically-inspired" approach (dragonfly).
