Abstract
A magnetic adhesive force monitoring system, magnetic wheeled robot and related method are disclosed. The system includes a magnetic field sensor measuring a stray field portion of a total magnetic field emitted by a magnetic wheel that is magnetically adhered to a ferromagnetic structure, the stray field portion including a portion of the total magnetic field redirected by the ferromagnetic structure. A controller determines a change in a magnetic adhesion force of the magnetic wheel to the ferromagnetic structure based on a change in the measured stray field portion of the total magnetic field. Embodiments also provide for determination of a contact point of the wheel with a ferromagnetic structure.
