Marvel’s four-legged robot climbs walls like a spider

People are always inventing ways to make their jobs easier. The construction of robots is the next logical step, although they are not yet so widespread. At least not those who walk on two or four.

The four-legged robots are now much more agile and even creepier. Researchers at the Korea Institute of Science and Technology (KAIST) have developed a four-legged robot with magnetic legs that can climb up and down metal walls and ceilings. A robot named Marvel was designed to assist humans in carrying out dangerous maintenance work on large metal structures. These include, for example, oil tanks, bridges or water towers. The robot uses a combination of magnetic elastomers and electromagnets to magnetize and demagnetize the surface to climb. This allows the robot’s feet to stay attached to the surface and then release when it takes its next step. Marvel is also able to test the surface with its front legs before striking, like testing the ice on the shore of a frozen lake to see if it is solid.

In laboratory tests, Marvel crawled up the wall like a spider, had no problem moving to the ceiling, crossing a 10 cm wide gap or climbing a 5 cm ledge. In a real-world deployment, this robot easily climbed an outdoor tank covered in paint and rust. It can carry up to three kilograms and can run up to 0.7 meters per second. And he is so wise that he even avoided obstacles. I wonder when we will see a similar group of robots everywhere.
