01.01.1970 //Robots will use guesses for the navigation in the space.
Periodical New Scientist writes that on the group of American researchers from the university By pard'yu develops the new algorithm, which will help future robots noticeably better to be oriented in the space. Experts note that this approach is capable to noticeably facilitate the task of the instruction of the robots of navigation in the complex buildings, the urban streets and localities unknown earlier. Developers note that until today the problem of navigation for the robot technology is most urgent and, at the same time, complex. The most popular approach for the solution of the problem of navigation consists in the load into the memory unit of robot local actual chart area and in the supply of robot by the system of satellite positioning. However, this approach is not universal, since it has many obvious minuses. At the university In pard'yu they say that people are oriented in the space otherwise - with the aid of the so-called "mental maps". This version for the realization in the machine form is very complex; however, it is much more effective. As it inculcated, different robotized mechanisms, which exist until today, are used laser scanners, odometers and other measuring devices for the navigation in the space. However, according to George whether, engineer from By pard'yu, until today is developed the algorithm, which will allow robot to assume the special features of locality, being based on the previous experience and on the maps. With the aid of the new algorithm the robot will be able to assume the landscape of locality with the larger or smaller degree of probability, being based on different initial data. "it is logical to assume that it would be learn rather well robots to obtain experience on the basis of data of primary navigation. On the basis of this experience the robots can be oriented better on by unknown by it locality "- say. The algorithm, developed by engineers is constructed on the base of the so-called "border zones", by which are understood the regions, which follow immediately after the territory, known to robot. In particular, if robot is oriented in the room and is encountered the wall, then it, being based on the assumption that the wall can have a completion, which overflows in, for example, into the door into another room, it will attempt to go around it. Each such assumption of robot obtains the degree of significance, also, in such a case, when it as a result proved to be accurate, then its weight rises. As a result the robot will obtain the base of data of the most precise assumptions, being based on which it will be possible to relatively accurately be oriented under difficult conditions. In the future on the base of this algorithm George whether with the associates is intended to create the more moved model, which will allow to construct its own maps robots. According to Andrews Davis, British of associate George whether, this algorithm will very well work in the locked and not very large accomodations. However, for the navigation in the open countries to robots will require either the enormous bases of data of versions or some already finished versions of actions.
