The Alicia/sup 3/ climbing robot: a three-module robot for automatic wall inspection

The system proposed in this article is the Alicia/sup 3/ climbing robot. The aim of this project is to develop a system that can be adopted in a variety of applications, such as maintenance, building, inspection, and safety in the process and construction industries. The system could be adopted in many places where direct access by a human operator is very expensive because of the need for scaffolding or is very dangerous due to the presence of a hostile environment.
