Abstract

The navigation system of mobile robot should have the capability of environment cognition, action decision, motion control, and state monitoring. This paper proposes a prediction algorithm route based on Voronoi diagrams, applicable for mobile robots with range sensors operating in indoor and unknown environments. The proposed control law is a hybrid navigation strategy composed of Voronoi diagrams and Delaunay triangulation, which is used to avoid the routes that may eventually block the advance of the robot. An efficient implementation of the control law is presented. Simulation results validate the efficacy of the proposed modified control law.
