Designing a serious-game-inspired digital laboratory for biomechatronics: a pilot study in engineering education

Introduction Virtual laboratories (vLabs) are increasingly used in engineering education to support preparation for complex experimental work. We report the implementation and exploratory evaluation of a serious-game-inspired vLab that mimics a biomechatronics device, the MyoRobot, within a Master's-level course. Methods The Unity-based desktop simulation combines a realistic 3D laboratory, an interactive technical anatomy model, and a pipetting and operation workflow that links virtual actions to plausible force-recording outcomes. In an initial cohort (N = 8), students prepared either using a written manual (n = 4) or primarily the vLab (n = 4). Open-ended questionnaires administered before and after the physical lab assessed perceived preparedness, confidence, engagement, and overall user experience. Results vLab users reported improved conceptual orientation and procedural confidence, along with greater independence in handling sensitive equipment. However, they also noted a higher perceived time investment, a reduced novelty effect during the physical lab, and a desire for more specific feedback. Discussion We interpret these findings as context-specific insights from a pilot study and derive design implications for realistic vLabs that aim to balance guidance, workload, and authenticity in engineering education.
