Multiple Abstraction Hierarchies for Mobile Robot Operation in Large Environments

This book focuses on the performance of mobile robots through the use of multi-hierarchical symbolic representations of the environment.To perform deliberative actions, a robot must possess some symbolic representation of its workspace, but representations of real environments can become so large that they must be conveniently arranged to facilitate and, in some cases, make possible their use. Practical solutions tested on real robots, for example a robotic wheelchair, are provided.
