With robots becoming an increasingly constant feature in daily life, we must prepare and educate current and future generations. Although robotics outreach and robotics education are not new in engineering education, many educators and outreach providers face the same hurdles when using educational robots: Educational robots are expensive to buy, can become obsolete quickly and are time-consuming to maintain. In addition, many people feel unequipped to select the right robot for their purpose. This paper describes the development and implementation of a family of modular, affordable, open educational resource, mobile robots called MIRTE, that can be implemented across the entire educational spectrum and how continuity of the robots is ensured by following the principles of Open Education and Open Science. In the paper, current educational implementations are highlighted and plans for future developments and future research are discussed.
