Welcome to WRO 2021

WRO 2021 PowerBots - The Future of Energy

At this page you can find the Games & Rules for WRO 2021. For each category there is a document with General Rules and for each Challenge there are seasonal Game Descriptions.

These rules are the official rules for the WRO Online International Final.
We realize that there are big differences between our member countries, for example in educational systems. This is why our National Organizers have the option to make adaptions to these games & rules so they fit the situation in the country. For our Regular Category we even give some examples for simplifications because the season challenges can be very hard for less experienced students at regional stages of the competition. 
This is why it is important to make sure you use the rules that apply in your country if you participate in WRO. Always use the rules your National Organizer provides, they will often also have a translated version.

Please be aware that there might be clarificiations and answers to questions about the rules on our Questions & Answers page. The answers given there are an official clarification of the rules.
