Locusts, flies, cockroaches and other insects are unlikelycan be called pleasant creatures. However, it is insects that often “throw” ideas for new developments to scientists. For example, not so long ago, researchers at the University of California at Berkeley created a cockroach robot. In addition to the fact that he does not possess the negative qualities of an insect, it is also almost impossible to crush him. Moreover, the new robot is potentially able to save more than a dozen lives.
How does a robot cockroach
Appearance designed by Californianthe scientists of the robot are impressive: it is about the size of a postage stamp. At the same time, the body of the robot is made of a very thin sheet of material called polyvinylidene fluoride (PVDF). PVDF belongs to the class of piezoelectric elements. That is, it reacts to an electric current in a certain way. When an electric current is applied to it, it is compressed. When the impact ceases - the material returns to the previous form. From above, the robot is covered with a layer of elastic polymer.

In the new robot current is supplied to two electrodes. They make the device perform a series of "flexions and extensions." In front of the robot is a special leg, which acts as a kind of "steering wheel", setting the direction of movement and turns. Due to this, the robot is able to easily move on a variety of surfaces.
Most miniature robots are very fragile. If you step on them, then most likely you will destroy the robot, ”said a professor of mechanical engineering at the University of California at Berkeley and development manager Liwei Lin. We found that if we give our robot a certain shape, it will be able to withstand such loads.

The speed of the robot is oncurrently 20 body lengths per minute. This may not seem like much, but the authors of the paper claim that their robot is much faster than all existing machines of this size. The weight of the robot is only 1 gram, while it can rise on high ground and carry a small load (weighing about 1 peanut).
According to scientists, such robots can beuseful in search and rescue operations, penetrating into places that ordinary means simply cannot get to. In this case, robots can, for example, provide an alarm button and send under the rubble. In this way, it will be possible to detect the localization places of survivors and save their lives.
