ABSTRACT
Remote teaching in engineering study courses has become more and more necessary since the start of the COVID-19 pandemic. Many classes have to be given online, and while more theoretical subjects can more or less easily be adapted to a pure online version, especially engineering courses are hard to replace by virtual classrooms. As most engineering students will at some time be employed in industry, only teaching virtual courses lacks building up a gut feeling for the technical devices and thus leads to required additional training and diminished value of the education. This paper gives an overview on protocols and systems for remote laboratories as well as a presentation of an example experimental setup, namely a hardware model of a sophisticated elevator having two cabins in one shaft. © 2022 IEEE.
