MICROCONTROLLER CIRCUIT TECHNIQUE AND THREE-DIMENSIONAL MODELING TOOLS IN THE STEM-TRAINING SYSTEM OF ROBOTICS

Abstract

The concept of STEM education is based on the practical application of knowledge and skills for their further use in professional activities. The project approach allows students to understand how STEM knowledge is applied in real life. The paper analyzes the developed and tested concept of combining the capabilities of educational robotics tools, three-dimensional prototyping and programming microcontroller platforms. 3D prototyping in robotics is effective because the user can quickly obtain results and implement their ideas in the design process. A robotic STEM project completed in the learning process can be not only an object of study, but also a tool for modeling, design, a tool in an educational experiment, a digital laboratory, a tool for programming microcontrollers. As an example, the technological aspects of manufacturing and programming SMARS platforms are given. SMARS (Screwless Modular Assemblable Robotic System) is a screwless modular assembled robotic system, a currently popular technological educational tool. These are simple robotic platforms designed for educational purposes with a minimum number of components that can be assembled without special additional tools. The sequence of project implementation and the specifics of programming their electronic parts – Arduino microcontroller platforms – are described. The main functions that SMARS can perform and additional design elements that expand the possibilities of its use are analyzed. Work on the design and manufacture of structures opens up wide opportunities for studying issues of a technological nature and activating the cognitive activity of students.In the process of project work, design and creative abilities are developed, and the foundations of professional and digital competence are formed.
