Abstract

This paper presents an innovative Challenge-Based Learning (CBL) project undertaken by undergraduate Mechanical/Manufacturing Engineering students from the REEdI (Rethinking Engineering Education in Ireland) program at Munster Technological University (MTU), Tralee. The project involved the fabrication, assembly, and programming of an ExoMy Mars Rover—a scaled-down, open-source robotic platform originally developed by the European Space Agency (ESA) as an educational analogue to the ExoMars rover. Students were tasked with interpreting ESA’s technical documentation, 3D printing 40+ custom components, sourcing electronic hardware, and integrating mechanical and software systems to produce a fully functional rover. The project emphasised multidisciplinary skills, combining additive manufacturing, mechanical assembly, electronics integration, and Python-based programming for autonomous navigation. This hands-on approach aligned with CBL principles by engaging students in a real-world engineering challenge that required problem-solving, collaboration, and iterative design. Feedback collected from the students indicated high levels of engagement and satisfaction. Students highlighted the tangible nature of the project, the opportunity to apply theoretical knowledge in a practical context, and the development of transferable skills such as teamwork and project management. Key lessons learned included the importance of early risk assessment for component tolerances, effective time management during iterative prototyping, and the need for clear documentation when adapting open-source designs. The project demonstrates the innovative potential of CBL in engineering education - leveraging space exploration themes to inspire creativity and technical competence. It also underscores the value of integrating emerging technologies nto undergraduate curricula to prepare students for Industry 4.0.
