Review:
This article provides a description of the developed models of the behavior of objects in the pursuit problem, as well as the pursuer and the pursued. The purpose of the conducted research is the development of algorithms for autonomous robotic complexes. In the proposed behavior models, local dynamic coordinate systems are introduced, which are formed by the direction of motion of the objects. During a certain period of time, the object must decide in which direction it should move depending on the result of the analysis of the coordinates of the second object. According to the proposed models of the behavior of objects in the pursuit problem, programs have been written in the computer math system “MathCAD”, which can be found on the author’s website. Due to the fact that the object, when moving in space, cannot instantly change the direction of motion, in our problems “inertness” is modeled using the angular velocity of rotation. The results of the programs obtained animated images of the movement of objects, references to which are given in the text of the article.
