Abstract: Solving the problem of determining the distance in the autonomous navigation system of a mobile robotic system is of great practical importance. For autonomous movement the robot must have a navigation system whose measurements prevent it from collisions with various obstacles. This paper demonstrates the control system of the distance measurement unit of the search robot. In practice, different kinds of robotic systems tend to move chaotically. For the organization of autonomous movement of the mobile robot it is necessary to equip it with measuring sensors and an intelligent processing system that prevents the robot from colliding with obstacles. The article deals with the principle based on the analysis of measurement results by ultrasonic distance sensor from the robot (sensor) to the front of the obstacle both in a static position and in the process of robot movement. The novelty of the paper lies in the fact that presence of an obstacle in the direction of the robot’s motion is determined by the time of the arrival of the reflected radio pulse emitted and received by the sensor in the ultrasonic frequency range. The project contains structural, functional and principal schematics. This research might provide increased precision and speed during indoor search and rescue operations. Other areas of mobile robotic systems application include mapping, protection of the premises and indoor service activities (cleaning, movement of goods), etc.
