Obstacle Avoidance Sensors: A Brief Overview

The mobile robots development, which is extremely relevant at the moment, is not limited to the creation of the robot design itself. In order for the robot to perform tasks and achieve its goals, it is necessary to develop a control system for it. When it comes to mobile robots, and even more so about autonomous robots, the tasks of planning the path of movement of the robot and its parts, including actuators, come to the fore. To perform such tasks, a variety of sensor-based sensing systems are widely used. There are a huge variety of different types of sensors that are used to control a robot. However, there are no ideal summer cottages for all conditions. they all have their advantages and disadvantages. That is, to select certain sensors, it is necessary to take into account various parameters of the robot itself and its environment. This article provides an analysis of ultrasonic, laser and infrared sensors. their advantages and disadvantages are described, and recommendations are given in which cases and what type of sensors is best to use.
