This paper addresses the cooperation of multiple aerial robots and fixed stations to monitor efficiently a perimeter divided in sub-paths with different priorities. It is not efficient to solve the problem following the elapsed time criterion and an urgency index is defined to normalize the elapsed time through the whole perimeter. The problem is defined as an allocation problem where the aerial robots...
Optimizing energy consumption of Micro Aerial Vehicles is one of several problems that remains to be solved in the domain of UAVs. In a recent work, a novel quadrotor was introduced that was able, when possible, to roll on the ground thanks to a tilting propeller and caster wheels. In the following work, we build upon this idea with a trirotor helicopter where all the rotors are independently tilting...
We present an approach for the automatic visual detection and position estimation of an air-to-air refueling drogue for unmanned aircraft. The drogue, which is dragged by an ahead flying tanker, is recorded by a passive color camera.
