Abstract
Recently, the demand for the nuclear reactor equipment has risen because of the demand for energy. Therefore, the demand for climbing wall robot that works in place of the person has risen further in the height and the hazardous area. However, A difficult problem hasn't solved that the magnetic adsorption power remarkable decreases on any ruggedness such as the welding parts and rivets on the iron structure. This problem has disturbed the development of climbing wall robot. Then, the development of a new mechanism "using the magnetic adsorption power" has been advanced. This report shows the development of climbing wall robot on the ruggedness by using new omni disc that makes the best use of the feature of magnet adsorption.
