Their level determines the possibility of further mastering by students of a promising specialty STEM-industry. It also involves the formation of the ability and willingness to solve complex problems, which is possible with the appropriate level of critical thinking, creativity, cognitive flexibility, teamwork, as well as the ability to implement research activities. In article determines the nature of the relationship between disciplines and the degree of integration. The place of project activity on robotics in school training is considered, describes the competencies that are formed as a result of such project activities. the possibility of teaching robotics to future teachers within the framework of existing educational programs is also considered.
