Abstract
This paper presents the mechanical construction of a climbing robot with wheeled locomotion and adhesion through permanent magnets. This machine is intended to be used in the inspection of different types of ferromagnetic structures, in order to, for instance, detect weaknesses due to corrosion, particularly in fuel tanks, ship hulls, etc. The vehicle will have a semi-autonomous behaviour, allowing a remote inspection process controlled by a technician, this way reducing the risks associated with the inspection of tall structures and ATEX places. The distinguishing characteristic of this robot is its dynamic adjustment system of the permanent magnets in order to assure the machine adhesion to the surfaces, even when crossing irregular and curved surfaces.

Abstract
Fractional Calculus (FC) goes back to the beginning of the theory of differential calculus. Nevertheless, the application of FC just emerged in the last two decades, due to the progress in the area of chaos that revealed subtle relationships with the FC concepts. In the field of dynamical systems theory some work has been carried out but the proposed models and algorithms are still in a preliminary stage of establishment. Having these ideas in mind, the paper discusses FC in the study of system dynamics and control. In this perspective, this paper investigates the use of FC in the fields of controller tuning, legged robots, redundant robots, heat diffusion, and digital circuit synthesis.

Abstract
This paper presents the architecture of a climbing robot with wheeled locomotion and adhesion through permanent magnets. This machine is intended to be used in the inspection of ferromagnetic structures, in order to, for instance, detect weaknesses due to corrosion, particularly in aerogenerators towers, fuel tanks, ship hulls, etc. The vehicle is designed to have a semi-autonomous behavior, allowing a remote inspection process controlled by a technician, this way reducing the risks associated with the human inspection of tall structures and ATEX places. The particular characteristic of this robot is its dynamic adjustment system of the permanent magnets in order to assure the machine adhesion to the surfaces, even when crossing irregular and curved surfaces. ©2010 IEEE.
