I. Introduction
Nowadays, developments in the field of unmanned aerial vehicles (UAVs) are one of the highest priority areas in robotics [1]. UAVs are widely used both for civil needs, for example, for organizing smart farms [2], warehouse management [3], traffic control for its subsequent analysis [4], covering large open spaces with a swarm of UAVs [5] and search and rescue operations [6], [7], and for military needs [8], [9]. Much attention of the scientific community is attracted by researches aimed at improving a UAV control process [10], [11]. According to statistics, from 21% to 67% of accidents while working with UAVs occur due to a human factor and an insufficient convenience of a UAV control [12].
