This course is intended for anyone who wants to master the Thymio educational robot, but it is especially designed for primary and secondary school teachers who want to learn about this tool and use it in the classroom. It allows teachers to acquire the basics of computer science and robotics, by proposing adapted problem situations, and by providing pedagogical tracks for the animation in class. It responds to the new programs for the introduction of digital sciences in schools in France and Switzerland and has been jointly produced by the Inria and the EPFL.
