FORMATION CONTROL AND ROLE ASSIGNMENT OF AUTONOMOUS MOBILE ROBOTS IN UNSTRUCTURED ENVIRONMENT

Abstract : Coordinating distributed robots to work in formation becomes one of the complex problems in multi-robot systems during the last years. The main contribution in the proposed work is to control non-holonomic mobile robots to maintaining a desired formation during navigation and the way to change formation shape when the robots detect a hindering obstacle. The robots are anonymous and randomly distributed. The developed control strategy, modeled using the Petri Nets formalism, combines together formation control, navigation and obstacle avoidance. The formation control is based on a leader-follower formation approach and the obstacle avoidance is based on modified limit-cycle method [1]. The overall control architecture is validated through a multitude of simulation.
