a Group of researchers at Zhejiang University in China have invented a device that allows robots or people to climb the walls. With the help of suction cups that you wear on your hands, you can climb even the steep, uneven surface – almost like a lizard or spider-Man.
According to engineers, all of which existed before the device was allowed to climb only on the surface, for example, glass or marble. Any touching of roughness resulted in a vacuum leak – as a result of the suction cups fell off.
Chinese scientists have resorted to the so-called ZPD method writes Phys.org. The edges of the cups circulates the water to maintain a uniform seal in the center and on the borders – to maintain atmospheric pressure.
“As shown by the experiments on the rough surfaces of the ZPD-a device weighing 0.8 kg generated suction power 245 H and consumes less than 400 watts,” said the researchers. A conventional suction Cup of the same size because of the strong air suction need a vacuum pump, which consumes several kilowatts and the West tens of kilograms.
In the next phase, the engineers are going to make your device completely offline, and also to reduce the level of water consumption – then the robot will be able to carry your own tank and not connect to the external source. It will involve cleaning Windows, building, rescue and other work performed at dangerous heights.
