Engineering End-to-End Remote Labs using IoT-based Retrofitting
CoRR(2024)
摘要
Remote labs are a groundbreaking development in the education industry,
providing students with access to laboratory education anytime, anywhere.
However, most remote labs are costly and difficult to scale, especially in
developing countries. With this as a motivation, this paper proposes a new
remote labs (RLabs) solution that includes two use case experiments: Vanishing
Rod and Focal Length. The hardware experiments are built at a low-cost by
retrofitting Internet of Things (IoT) components. They are also made portable
by designing miniaturised and modular setups. The software architecture
designed as part of the solution seamlessly supports the scalability of the
experiments, offering compatibility with a wide range of hardware devices and
IoT platforms. Additionally, it can live-stream remote experiments without
needing dedicated server space for the stream. The software architecture also
includes an automation suite that periodically checks the status of the
experiments using computer vision (CV). RLabs is qualitatively evaluated
against seven non-functional attributes - affordability, portability,
scalability, compatibility, maintainability, usability, and universality.
Finally, user feedback was collected from a group of students, and the scores
indicate a positive response to the students' learning and the platform's
usability.
