The official competition rules and scoring criteria are primarily subject to the guidelines in each year's rulebook. We have provided the link to our latest 2027 rulebook below for your reference: https://www.worldgreenmech.com/images/FileUpload/2511_2027 WGM Contest_Regulations.pdf Each competition rulebook is designed by its Chief Referee, who also provides rule explanations and training slide decks for participating teachers.

According to regulations, we hold the WGM in August. We recommend that each country complete its National Competition two months prior (May to June) to select national representatives. Regional competitions should be completed two months before the National Competition (March to April). However, if a region has too few teams to hold a regional competition, holding a single National Competition to select the representatives is also acceptable.

The schedule for each competition will be announced in the official rulebook. Taking the 2027 R4M competition as an example, you can refer to pages 33–34 of the rulebook for the competition timeline (pictured below). Please note that this schedule is for reference only; adjustments may be made based on actual circumstances for events with fewer teams, such as regional or national competitions.

As mentioned in point 4 above, the Chief Referee will provide the training presentation materials needed for school teachers. The content will include the rules for each competition category, as well as guide teachers in building sample models and conducting hands-on simulation practice on the actual venue field. Please note that the 2027 rule briefings and training slides are currently under preparation; please feel free to request them from us at any time if needed.

Please refer to the 2027 competition rulebook.

Regarding certificates, both Certificates of Guidance (for advisors) and Certificates of Participation will be available for download from the official website for all registered teams. Additionally, individuals serving as judges for the World Championship will receive official Judge Appointment Certificates. For the planning of World Championship awards and trophies, please refer to the annual rulebook—for example, page 12 of the 2027 rulebook (pictured below). For national competitions, organizers may adjust award categories and structure according to their country's specific circumstances.
