Questions & Answers
At this page we will publish frequently asked and important questions related to the WRO® 2020 games. The answers on this page should be seen as additions to the rules and will be used for the WRO International Final. Be aware that in your country local competitions may follow slightly different rules. Always use the rules provided by your National Organizer.

All age groups
Rule 6.9 prohibits the destruction of objects. If the strategy is to destroy object to solve tasks the team would be penalize. If an objects accidentally breaks it is not a problem, but broken objects cannot score points.
Teams are allowed to use a second controller to charge the battery of the SPIKE robot. The controller has to stay on the team table and visible for the Judges. It cannot be used for a robot.

Yes, the eggs have to stand upright. No points are awarded if they lay on the side.
The vending machine will be fixed on the mat. It is not allowed to move it. If the vending machine is moved the eggs do not score points.
The green 1×6 bricks on top of the vegtable detach quite easily. When the elements are still connected the vegetable still counts as complete (see picture). If they are fully seperated from the rest of the vegetable, no points are scored for that object.
Yes, the water element can be placed on the robot. It is important to keep rule 6.6 in mind: The robot together with the water element has to fit in the 250 mm X 250 mm X 250 mm size limit. The water element has to be in the starting area even it is not used.
Junior
Yes, the windmill must be upright. This means that the base must touch the ground completely. It is permitted for the robot to touch the windmill.
The lakes and green elements have to touch the mat with the full base area of the object to score points. If the object is tilted a little bit, it is not considered in an upright position. The object must not lie on or be supported by other objects.
No, to get the full 11 points the cable is not allowed to touch anything else except the charing area B.
Yes, the cable can be placed on the robot. It is important to keep rule 6.6 in mind: The robot together with the cable has to fit in the 250 mm X 250 mm X 250 mm size limit. The cable has to be in the starting area even it is not used.
A green starter set is considered inside the house, if it is only touching the green area inside the house.
Senior
No, it is not allowed to damage the stands. No points for all green and blue house elements will be awarded if a stand is damaged.
* The word “all” was added for clarification on 28th of November 2024.
No, the house elements are placed loosely and not pressed firmly.
The lowes house element can always score points. If any of the other / higher house elements is touched by the robot (or any other object) all of them cannot score points any more. The only exception is the lowest element on the ground.
Example: I team build a house with three floors, but the robot still touches the highest element. In this case only the element on the gound can score 3 points. The second and third element cannot score points.
RoboSports
The orange balls are placed on the half where they fell off the table. The purple balls are placed on the opposing team’s side.
Flying robots are forbidden.
No, it is not allowed to show orange or purple on a display.
Any attempt to distract the opposing robots is considered unsportsmanlike conduct and will result in exclusion from the competition
No, boost converters are not allowed.
The control software is all the software that is used to control the robot and its components. Any programming language can be used.
The main controller of each of the two robots are allowed to communicate to each other. This mains, that only the LEGO-Controller or the main Arduino Controller can communicate with each other. It is not allowed to add additional components for communication.
Make sure to choose a controller that has that functionality build in.
- Brushless DC electric motor (BLCD motors)
- Solenoids
- Linear motors
