In the modern world of electronic devices, a person can bring to life any projects that make their life more comfortable and safe. The basis for such solutions is robotics. Creating and programming a robot today is quite simple. We offer the experience of conducting long-term projects that can take place in summer camps, scientific studios, and extracurricular clubs. The uniqueness of such activities lies in the combination of various types of work that help explore the topic and conduct scientific and technological research. Mastering robotics technology and understanding the principles of their operation is an important aspect of preparing modern children for a safe life in a high-tech world and successful self-realization. The foundation for the study and effective application of these technologies is mathematics, physics, engineering, and programming. Therefore, STEM education, aimed at developing competencies demanded in society, increasing motivation to study traditionally challenging subjects of the natural-mathematical cycle, is of particular importance. The peculiarity of this approach to education is project activity and transdisciplinarity, contributing to the formation of teamwork skills, critical thinking, and a comprehensive understanding of the researched problem. The article presents the experience of a volunteer project to teach robotics to children from Ukraine. Organizational conditions for conducting classes, typical difficulties, examples of projects, and the lesson scenario are provided. The proposed approach to organizing education is based on years of practical experience and can be used by educational institutions and non-profit organizations.
