In the last decade, the multirotor aerial vehicles (MAVs) have become popular in research and in relatively simple applications such as aerial photography, structural inspection, and crop monitoring. On the one hand, we can observe the maturation of the autonomy capacity of MAVs that are now commercially available and, on the other hand, the desire for solutions in highly critical applications, such as electric VTOL or delivery goods, both in urban areas. A typical scenario for the mentioned critical applications requires vehicles endowed, inter alia, with the ability to perceive and deviate from obstacles that can be fixed (e.g., represented by buildings) or mobile (e.g., represented by other MAVs). Considering this kind of scenario, the present text proposes to investigate the problem of MAV guidance with obstacle avoidance. The general sense & avoid problem can be divided into two subproblems: one of perception and one of guidance. The subproblem of perception will not be the subject of this investigation; for experimental demonstration purposes, a suitable sensing system (a 3D camera) shall be adopted. With respect to the guidance subproblem, which is in fact the focus of this work, the robust and stochastic model predictive control strategies (RMPC and SMPC) will be adopted as the main research methodology. The methods to be proposed in this project will be evaluated in hardware-in-the-loop (HIL) simulation and in flight tests conducted indoors with two small quadricopters. (AU)
