Students in the class know the existence of robots and their categorization into robots with direct human control (remote controlled robots) and autonomous robots controlled by a programmed computer. The second category is also the one that they should study and provide solutions to complete the scenario. The teams first create a construction from guided slides and after completing it they program the robot to avoid obstacles in front of it. Students will study and experiment both in the virtual (through the Scratch program ) and in the real world (robot built with WeDo 2.0 "bricks"). Students should have basic computer skills ,know the building blocks of the Lego package WeDo 2.0, have built simple robotic constructions and know basic commands from the Scratch programming environment .
