Automatic device for remote measuring of circularity: Development and implementation in education courses

Abstract

In conjunction with the development of technology, teaching in educational institutions around the world has also changed from traditional teaching, where blackboards and chalk were used, to modern teaching with blended or completely online learning environments. Online teaching became a necessity over the past year as the COVID-19 pandemic occurred throughout the world. One of the biggest problems that arose was the impossibility of students to work with equipment on the spot during laboratory exercises. In turn, many universities have used labs with physical devices that can be launched remotely through the Internet from anywhere. One such device is presented in this paper. An automatic device for the remote measurement of geometric tolerances, circularity, was developed and applied in the teaching process at the University of Novi Sad. The exercises were performed by students who remotely started and controlled the device and measured the deviation of the actual from the defined diameter of the work piece in the desired cross section. At the end of the semester, students completed an evaluation questionnaire and expressed satisfaction with the implementation of this exercise.
