Abstract This paper describes a multi-loop, modular navigation architecture for mobile robots whose structure allows the execution of most types of navigation tasks in a highly robust manner. The modularity allows the clear separation of functions according to their complexity and priority. We propose a clear separation between local and global navigation in such a way that both can run independently, but an adequate alternation/competition between them allows accomplishment of trajectory execution including avoidance of unknown obstacles. The multi-loop nature of the architecture ensures adequate stability at different levels yielding safe navigation and accomplishment of higher level tasks. Examples may range from goal reaching in some point of the environment to a 3D-environment mapping application, as this is the case in this work.

In this paper, a new online robot motion planner is developed for systematically exploring unknown environ¬ments by intelligent mobile robots in real-time applications. The algorithm takes advantage of sensory data to find an obstacle-free start-to-goal path. It does so by online calculation of the Generalized Voronoi Graph (GVG) of the free space, and utilizing a combination of depth-first an...
