Scientists have learned a spider jump, then to teach robots
University of Manchester scientists have spent a lot of time in the laboratory. They taught spiders jump and recorded on a high-speed cameras to study in detail the behavior of the spider during a jump. The aim of the scientists is to create a jumping robot. Why for this purpose it is spiders were chosen? No other creature does not bounce like a spider.
Many insects and arthropods are able to jump over very long distances, if we compare the distance to their own size. Man, as a rule, can not jump over a distance of more than 1, 5 the length of his body. But among all spiders highlights another feature. If insects are often jumping to escape, jumping spiders to attack its prey. This makes jumping spiders more coordinated. Spiders assess the environment in order to make the leap.
For their work, scientists went to the pet store where purchased four royal jumping spiders. It is one of more than 6,000 species of jumping spiders, which belongs to the family of arthropods Salticidae. For spiders, they built a platform with platforms and high-speed cameras. After that, scientists have begun to the most complex - they need to be taught spiders jump. Selected jumping spider missed one week of production in order to feel full. For this reason, the bait has been difficult to get the spiders to jump. Scientists have just moved the spider from one platform to another in order to show that it will do the spiders. As it turned out, it was only a trained spider Kim. Three other spiders simply refused to jump.
For the week spider Kim made 15 jumps, different in length and height. She jumps off the platform, jump on it, to move to a platform at the same height. At the same time it generates a certain amount of web. Scientists believe that this is for security reasons in case the objective will not be achieved as a result of the jump. But the interesting thing is that the various legs were used for different types of jumps. The movement of the legs and is the most valuable result of the study.
Scientists believe that it is those robots, which will be endowed with spider skills will be able to jump high enough. If they are able to study in detail the behavior of the spider during a jump, robots will be able to jump up to the heavens.
