This eTwinning project will serve as the online documentation and interaction of the KA2 Erasmus+ project „Exchange of ICT practices: Java robot programming in a European context“ 2019-2021, in which we would like to introduce object-oriented programming to robotics classrooms in Europe. This concept can be applied to LEGO EV3 Mindstorms robots which are widely distributed in schools in entire Europe and North America. Our programming work but also our cultural experience in our trips to Munich, Samos and Ragusa will be documented here.
