Roboticists at the Korea Institute of KAIST, together with colleagues from the University of Illinois in the United States, have developed a Marvel robot that can climb walls and ceilings. With the help of the robot, they plan to check oil tanks, bridges, water towers and other metal structures. The limbs of the MARVEL robot are equipped with magnetic elastomer components and traditional electromagnets. The electronic control system allows you to magnetize each of the limbs of the robot at the right time. Before climbing the wall, the robot, like a cat, checks the surface. Tests have shown that the MARVEL robot is capable of carrying a payload of up to 3 kilograms and moving along a horizontal surface at a speed of up to 0.7 m/s.
