— This paper considers the navigation in formation of a mobile Multi-Robot System (MRS) in presence of obstacles. In such areas, the collision avoidance between the robots themselves and with other obstacles (static and dynamic) is a challenging issue. To deal with it, a reactive and a distributed control architecture is built. The navigation in formation of the MRS is ensured while tracking a global virtual structure (first controller). Limit-cycle principle is used to compute the set-point of the obstacle avoidance task (second controller). In this paper, kinematic constraints of the robot are taken into account in order to generate an attainable set-point. The objective is to guarantee safety of the mobile robots with respect to their maximum velocities. Simulation and experimental results validate the proposed contributions.
