Using aerial robots in area coverage applications is an emerging topic. These applications need a coverage path planning algorithm and a coordinated patrolling plan. This paper proposes a distributed approach to coordinate a team of heterogeneous UAVs cooperating efficiently in patrolling missions around irregular areas, with low (More)
This paper proposes a distributed approach to solve long endurance area surveillance missions with a team of quad-rotors, taking into account the communication constraints. The presented system based on “one-to-one” coordination ensures to get a near optimal solution keeping a periodic information interchange between all the members of the team. A set of(More)
This paper presents the decentralized strategy followed to ensure information propagation in area monitoring missions with a fleet of heterogeneous UAVs with limited communication range. The goal of the team is to detect pollution sources over a large area as soon as possible. Hence the elapsed time between two consecutive visits should be minimized. On the(More)
This paper presents a decentralized algorithm for area partition in surveillance missions that ensures information propagation among all the robots in the team. The robots have short communication ranges compared to the size of the area to be covered, so a distributed one-to-one coordination schema has been adopted. The goal of the team is to minimize the(More)
This paper presents the perimeter surveillance problem using a set of cooperative robots with heterogeneous speed capabilities under communication constraints. The problem is solved using a frequency-based approach. In the proposed path-partition strategy, the robots patrol a segment length related to their own capabilities and interchanges information with(More)
In monitoring missions, using a cooperative team of Unmanned Aerial Vehicles (UAVs), the goal is to minimize the elapsed time between two consecutive observations of any point in the area. Techniques based in area partitioning achieve the goal when the sub-area assigned to each UAV is according to its capabilities. In previous work of the authors [1] it was(More)
This paper addresses the area surveillance problem with a team of multiple aerial robots under communication constraints. In previous work of authors [1], a decentralized modular architecture was proposed for surveillance missions with a team of homogeneous robots. This paper presents a decentralized decision-making algorithm that solves the problem for(More)
Exploiting wind currents in the environment allows autonomous gliders to gain altitude and energy and consequently extend flight duration. This paper considers the problem of a persistent monitoring mission using multiple autonomous gliders and exploiting thermal soaring. Communications constraints and non-homogeneous teams of gliders are considered. A(More)
