During the mastering of the discipline "Mechanical Engineering: Fundamentals of Robotics" the student must obtain a certain level of subject competence, which is determined by the knowledge, activity and value components. For future specialists in digital technologies, the key is information and digital competence, which allows the graduate to quickly navigate in the rapidly changing information space, systematize information and draw logical conclusions. The application of 3D-printing technologies in educational robotics is one of the most relevant areas, which significantly expands the possibilities of practical application of acquired knowledge during the study of the discipline. The main difference from the classical approach to the use of 3D printing technologies in the educational process of secondary schools, where the 3D printer is used to implement students' creativity and materialization of virtual objects, in educational robotics it can act as an object of study - a classic example of a robotic system. which in comparison with educational works not only models possibilities of industrial robots, but also allows to make a useful product. Interdisciplinary integration, on which educational robotics is based, contributes to the natural interest of man (pupil, student) in the development and design of various mechanisms. At the same time, robotics classes are suitable for learning the basics of algorithmization and programming, allowing students to see how their knowledge allows them to transfer action from virtual, computer space to the world of real, real objects. And this is of great psychological importance in our time, where the passion for virtualization is clearly excessive.
