Created robot cockroach, which is almost impossible to crush

Locusts, flies, cockroaches and other insects can hardly be called pleasant creatures. However, exactly the insects are often "toss up" scientists ideas for new developments. For example, not so long ago, researchers from the University of California at Berkeley have created a robot cockroach. Besides the fact that he does not have the negative qualities of the insect, so it is also virtually impossible to crush. Moreover, the new robot has the potential to save more than a dozen lives.

How does the robot cockroach

Appearance Californian scientists developed a robot is impressive: it roughly the size of a postage stamp. In this case the robot body is made of very thin sheet material called polyvinylidene fluoride (PVDF). PVDF belongs to the class of piezoelectric elements. That is, it responds to an electric current in a certain way. When it is fed electric current - it is compressed. When the exposure ends - the material is returned to the previous form. Top coated layer robot elastichenogo polymer.

The new robot current is applied to the two electrodes. They cause the device to perform a number of "flexion and extension." In front of the robot is a special foot, which acts as a sort of "wheel", setting the direction of movement and rotations. Due to this the robot is able to move on a variety of surfaces with ease.

The majority of miniature robots are very fragile. If you step on them, the more likely you are to destroy the robot, - says professor of mechanical engineering at the University of California at Berkeley and leader Liwei Lin development. We found that if we give our robot to a certain shape, he is quite able to withstand such loads.

Why a robot cockroach

Speed ​​robotarakana movement is at the moment 20 of the lengths of his body in a minute. This may seem small, but the authors of argue that their robot is much faster than any existing machine of this size. Weight robotarakana is just 1 gram, can he climb the hill and carry a small weight (weighing approximately 1 peanuts).

According to the scientists, these robots can be useful in search and rescue operations, getting into places that conventional means there simply will not work. In this case, the robots can, for example, to provide the alarm button and send the rubble. Thus it will be possible to detect survivors localization and save their lives.
