Optimization of Distance Between Magnets for Magnetic Wall Climbing Robots

In this paper, an adhesion system used for magnetic wall climbing robots using permanent magnets is examined for its change in adhesion concerning the inter-magnet distance within the Yoke. Pocket milled ferrous material of high permeability named yoke is used to hold neodymium magnets in mobile wall-climbing robots. For a climbing robot, the self-weight is a significant parameter which needs to be at the minimum possible value. This simulation study is expected to help in bringing down the weight of the yoke holding magnets and help in finding the right inter magnet distance for the magnets used. Simulation studies were carried out for various inter magnet distances and the values are reported. An optimized distance was arrived using the simulation results thus obtained.
