Dead spiders turned into robotic claws

Dead spiders turned into robotic claws

Necrobotics.

Did you notice that spiders, dying, roll around like these researchers? "," says Faye Yap, one of the engineers responsible for the project, in a statement by Rice University.

The answer has not kept itself waiting for long: spider movements, unlike ours, depend on hydraulic principles. The field near the head, called the sonic chamber, is reduced to direct blood to the extremities, which allows them to expand. When this pressure weakens, the legs are reduced. When the spider dies, it no longer sends blood to its legs, hence and this position. "," scientists thought. So they decided to take advantage of this mechanism in a seemingly unexpected way. Their study on this issue was published in a magazine.

They decided to revive the bodies of spiders by injecting air into this hydraulic system, which they said was an "ideal architecture" for that purpose. The method used is relatively simple. They stuck a needle in a som chamber and sealed it with superglue. This allowed them to inject a small amount of air to "replace" the blood that usually comes to their feet and thus take control of it.

The tests carried out on these spiders with necrotic claws, according to scientists, were successful. They were able to force them to lift 130% of their body weight. They repeated opening and closing cycles and were able to pass up to 1,000 cycles before they noticed signs of wear. ", they say.

From soft robotics to necrotics

In the view of engineers, the use of spider bodies for robotics can have a number of applications; among other things, they mention very small-scale tasks, insect fishing, or the restoration of objects in nature; of course, such "components" are also biodegradable; scientists are also testing new types of materials.

Preston Lab, where the project was born, specializes in the use of innovative materials for so-called "soft robotics", unlike the use of metal, plastic, electronics, etc. We use all kinds of interesting new materials, such as hydrogels and elastomers, that can be activated through chemical reactions, pneumonia and light. "," says Daniel Preston.

Clearly, spider corpses seemed a logical extension of all these experiments. ", he adds. " Indeed, robotics often imitated spiders because of their ability to navigate under harsh conditions and their hydraulic design.

To justify the potentially shocking aspect of their tests, scientists compare them to the tools of past years made of animals: "." They also considered it necessary to note that they do not revive spiders, but simply force them to move like puppets. Now they want to work on managing the "clubs" that allow individual leg movements.
