To address the local path planning problem for autonomous land vehicle in unstructured environments, a novel method combining navigation function and A* search is proposed. The computed navigation function in this paper embodies different constraints of vehicle, so in fact to be a near-feasible trajectory. Next the navigation function and sensed obstacles is used to construct the heuristic function,...
A dynamic path generation approach to find an admissible path in totally unknown surroundings is presented. The proposed approach is a method to find a reasonable trajectory in unknown obstacles. This avoidance algorithm is based on the potential field approach, and there are some differences and innovations from those methods because a navigation function to handle considers not only position of...
This paper presents a strategy for improving motion planning of an unmanned helicopter flying in a dense and complex city-like environment. Although Sampling Based Motion planning algorithms have shown success in many robotic problems, problems that exhibit ldquonarrow passagerdquo properties involving kinodynamic planning of high dimensional vehicles like aerial vehicles still present computational...
