Facilitation of obstacle detection by utilization of low-cost sensors in the case of mobile robots

The aim of this paper is to introduce a novel method for facilitating the detection of surrounding obstacles in the case of inexpensive mobile robots. For this purpose, a cheap ultrasound radar and a simple camera were used. By combining the signals of these two sensors, the robot was able to determine the distance, orientation, and dimensions of the objects located around it. Beside software methods, the quality of the detection was improved with practical approaches as well.
