Around the world, engineers are creating robots, inspired by the plasticity and capabilities of insects, so now there are a huge number of all kinds of robots, butterflies and caterpillars that are pretty good at crawling, walking, jumping and even flying. At Harvard, they went further and created arachnids from ordinary cocktail tubes. As it turned out, they are not only excellent for sucking out soft drinks from glasses, but also help engineers out of the cold if they need to create cheap but practical and flexible joints for their new robots.
To make a joint for a robot, you just have to cut the tube, bend it over the notch and fasten it with a piece of rubber hose. Then, with the aid of a small pneumomechanism, air is injected into the tube, and it straightens. If it is pumped out from there, it bends.
Robots are excellent. They can run on any surface with a complex terrain, they do not weigh anything, and thanks to their flexible construction they can get into hard-to-reach places or jump higher.
Developers have already tested robots with two, three and six limbs. To perform serious tasks, spiders from tubes are not suitable, but the idea is in any case interesting.
