Engineers often take inspiration from living organisms when creating robotic arms. But
What is known
Spiders do not have muscles, and their limbs arethe action of a kind of hydraulics, which is controlled by a separate body. It makes the paws shrink. The organ itself is located in front of the body of the spider and is called the prosoma or cephalothorax.
Texas researchers have developed a mechanism that can move limbs in dead individuals. The area of research is called necrobiotics.

Specialists insert a needle into the cephalothorax andattach it to the body of a dead spider. Through a syringe, researchers can enter or pump out air, as a result of which the limbs of the arthropod begin to move.
Empirically, it was found that such a captureable to lift a load, the weight of which exceeds the weight of the spider itself by 130%. According to the scientists, one spider is enough to complete 1,000 gripper open/close cycles before tissue degradation begins. In theory, a polymer coating can extend the service life.
The experiment was not done for fun. According to scientists, such manipulators can be useful when mounting and moving small objects. In particular, when assembling microelectronics.
