The necrobots are here: scientists create robots from spider corpses


The concept of necrobots, robots built from dead entities, is something relatively recent and almost out of the realm of science fiction. But sometimes, as has just happened with the rice universityreality ends up reaching what started as a product of the (twisted) imagination.

The spiders they are impressive insects that also represent a strange source of fascination for many individuals. To the extent that many people often have them as pets in their homes.

But regardless of this, one of the most fascinating factors around arachnids is the qualities of their anatomy, where their physical constitution could well be considered a masterpiece of mechanics and engineering.

That at least appears to be the position of research scientists at Rice University who ended up turning a series of spider carcasses into pincer-like robots.

The necrobots made with spiders with Rice University

The complete research project, signed by Daniel Preston and Faye Yap from Rice University in the United States, has been published in the most recent edition of Advanced Scienceat the same time that it can also be consulted online.

Even through its official YouTube channel, the university has published an explanatory video where these necrobots can be seen in action, armed through a species known as “wolf spiders”, which were able to lift more than 130% of their own body weight:

As can be seen in this “Necrobotics” experiment, the robots were used as grippers and proved to be functional for about a thousand grasping cycles before beginning to fail.

They achieved this thanks to the spiders’ own metabolic architecture which, having no muscles, works based on the principles of hydraulics, with a cephalothorax that contracts and distributes body fluids to its legs to extend them and increase their strength.

In the experiment, the researchers injected a syringe into a spider’s cephalothorax, sealing any possible leaks with glue to assemble a hydraulic system.

The syringe delivered air through the syringe to the body of the spider, the air activated the cavities from the cephalothorax and reached the legs to acquire movement.

In the video we see how the system worked in principle to build a series of necrobots with claw function.

The conclusions of the project affirm that these robots created from corpses could be a biodegradable solution.
