Abstract

This work is concerned with the adequate selection, evaluation and experimental optimization of a low-cost position sensor in an electromechanical system. The objective is to choose a sensor that satisfies the following criteria: it is very fast, provides accurate measurement, and is relatively inexpensive.
Various distance measurement technologies, including vision, laser, acoustic, and touch sensors, have been evaluated. Ultrasonic sensors deliver the best performance in terms of cost-effectiveness and applicability.
The developed system undergoes static and dynamic testing, with structural, environmental, and software adjustments improving measurement accuracy. The research significantly reduces measurement errors and enhances result repeatability. The article discusses challenges associated with ultrasonic sensors, such as acoustic resonances and environmental influences, and proposes mitigation strategies. The findings highlight the extensive potential of the system for various industrial and educational applications.
