WRO Categories
At WRO we offer challenging competitions for everyone in the age from 6 up to 25. We have four competition categories, with their own characteristics and challenges:
- Regular Category
- Open Category
- WRO Football
- Advanced Robotics Challenge
Each season the challenges and theme for the Regular and Open Category are developed with the country that hosts the International Final. The WRO Football rules and the Advanced Robotics Challenge game are designed together with experts in our community.
