In the 21st century, robotics represents a high level of interest for both teachers and researchers, this branch of science being a valuable tool for developing cognitive and social skills for all students. Robotics gives students a more interesting vision of science and engineering, leading to the development of STEM education (4 disciplines: science, technology, engineering and mathematics) and other school subjects or interdisciplinary learning activities.The purpose of this article is to study the impact of robots, using the Lego Mindstorms NXT software, on students in terms of the skills of the scientific process, their scientific creativity and their perception of "robots, people and society." The use of the Lego Mindstorms NXT software in the educational instructive process gives the specialty lessons advantages such as: development of integrative thinking or stimulating the creativity, flexibility and adaptability of the pupil to respond in a timely manner to the changing needs of the labor market.
