The purpose of this paper is to present a navigation system designed for highly dynamic environments which is independent from a metrically exact global map.
A navigation system is developed to cope with highly dynamic environments. Here, this refers especially to changes in the environment itself, like the daily deployment or removal of advertisements or special offers in a supermarket. The navigation system is split into a global part, relying on non‐concealable artificial landmarks and a local part containing a behavior‐based control using a dynamic potential field approach. The required information are the definitively static structures and the actual sensor information only.
The system proved to be useful in environments that change frequently and where the presence of many people complicates the perception of landmarks.
The presented navigation system is robust against changes in the environment and provides reliable collision avoidance capabilities.
It is a useful navigation system for autonomous robots dedicated to frequently changing and populated environments.
