Permanent magnetic climbing robot design and calculation of adsorption

Many special industries exist altitude, toxic, flammable, explosive and other dangerous work environment and serious threat to the lives and safety of the staff. Development of special robots to replace human work is urgent need. Therefore, the development of special automated robot instead of doing physical labor is the future trend of social development . In recent years, wall-climbing robots in the nuclear industry, petrochemical industry, construction industry, shipbuilding industry, power industry and other fields has been in-depth study and the rapid development, especially adapt inclined or vertical wall and capable of spider climbing robot. Because of its inspection, cleaning, descaling, coating thickness measurement and other functions, it can reduce the risk of manual operations, improve operational efficiency, reduce operating costs and in the research and application of widely. This paper presents a new wheel permanent magnetic wall-climbing robots structural design, including adsorption system and motor systems and power systems, for the second adsorption system permanent magnet material selection and arrangement of analysis design, finally that variation of suction force at different gap conditions between the air gap and the permanent magnet.
