Abstract: The present invention aims at developing a robot for applying coating in regions called “difficult access areas” of offshore platforms and ships, such as curved, vertical surfaces, or surfaces with negative inclination angles. The design concept was developed based on a low-weight painting system, integrated into a vehicle with magnetic shoes (104), which produces a constant magnetic force on the metallic surface, capable of guaranteeing the support of the vehicle in the different areas of application. The floating magnetic system aims at ensuring that the wheels (102) have the necessary friction for the vehicle to move.
