US Scientists Turn ***** Spiders Into Robots That Can Pick Different Objects

Scientists have worked out how to turn ***** spiders into “necrobotic spiders” that can mechanically grip objects. 

Researchers at Rice University in the ******* States released a report of their experiment in the

Advanced Science, in which they were able to repurpose the bodies of ***** spiders by pumping air into their legs to extend them and pick things up. According to the authors, this invention might be used for a variety of tasks, such as catching insects or even putting together microelectronics.

Science Alert, the researchers described the creation as “necrobotics”. “It happens to be the case that the spider – after it’s deceased – is the perfect architecture for small-scale, naturally derived grippers,” said Rice University engineering professor Daniel Preston, in a

The team explained that spiders use hydraulics to move their limbs, as opposed to people and other mammals who use muscles. A chamber near their heads contracts to send blood to limbs, forcing them to extend their limbs. While the pressure is relieved, the legs contract.

The researchers worked out a way to manipulate the hydraulic system. They inserted a needle into the spider’s prosoma chamber and created a seal around the tip of the needle with the help of super glue. Then, they squeezed a tiny puff of air through the syringe, which was enough to activate the spider’s legs. They were able to achieve a full range of motion in less than one second. 

The team was able to unlock new ways of performing pick-and-place tasks. They were successfully able to make a ***** spider grip onto different objects. Their testing showed that ***** spiders can lift more than 130% of their own body weight, and sometimes much more.

“They had the grippers manipulate a circuit board, move objects and even lift another spider,” the press release read. The team noted that smaller spiders carry heavier loads in comparison to their size. Conversely, the larger the spider, the smaller the load it can carry in comparison to its own body weight.
