WRO 2018 Elementary Category

The preparatory course for participation in the Elementary Category of the WRO 2018 consists of the classes that gradually draw the students to their own robot creation. Considering the basic robotic kit as an example, all the tasks that the robot deals with are carefully considered, as well as the ways of their solution.

This course consists of 12 stages that will help you prepare a team for World Robot Olympiad and achieve stable results. Suitable for beginners and experienced teams.

  • 12 stages curriculum
  • Step-by-step interactive prasentations
  • Building instructions for robot, modules and manipulators
  • Programs for compleate all of the missions
  • Theoretical information about constuction and programming
  • Ideas for robot upgrades and your own projects
  • Strategy and planning
