The main purpose of the project is to help students to improve their knowledge through robotics and STEAM activities. Students will learn how a robot moves, what is the role of sensors and how they can detect an obstacle. For this they will use previously acquired mathematical and physical notions. They will do this in a first stage on a virtual platform that has a simulator (https://lab.open-roberta.org/, VEXcode VR /), then in the second stage on specific platforms, with the effective help of robots. Students will then present their projects on online communication platforms and receive feedback from colleagues and facilitators.
