—The problem of managing a fleet of quad-rotor drones in a completely unknown environment is analyzed in the present paper. This work is following the footsteps of other studies about how should be managed the movements of a swarm of elements that have to stay gathered throughout their activities. In this paper we aim to demonstrate the restrictions of a system where absolutely all the calculations and physical movements of our elements are done by one single external element. This is made possible thanks to a set of command rules which can guide the drones through various missions with defined goal. This strategy is based on a simultaneous usage of different data: obstacles positions, real-time positions of all drones and relative positions between the different drones. This work is based on Robot Operating System (R.O.S.) and use, as a base, several previous open-source projects on the matter. Simulation results show the limitations of the use of a centralized system to control a fleet of drones. Those weaknesses are highlighted thanks to the low-cost drones used here where the central unit had difficulties to handle drones workload.
