Clarification regarding bonus points2023-06-13T14:48:46+02:00

Each age group has a task called “Get bonus points “.
These bonus points are always scored, regardless of whether or which tasks a team solves.
Even if the robot does not leave the starting area, the bonus points are awarded.

Is it allowed that the robot loses parts on the field?2023-05-08T14:42:19+02:00

If there is a LEGO piece on the playing field that is no longer touching the robot, it is no longer counted as part of the robot.

The robot may loose any number of parts on the playing field during a round, except for the controller, sensors and motors.

What kind of “projection” scores for robot end situation?2023-03-16T07:56:13+01:00

In this years rules, it is enough if the projection of the robot is partly inside the finish area.

This could be with any part of the robot. Technically, a situation like with such an arm / beam that is connected to the robot would be enough.




INTERNATIONAL FINAL: Clarification regarding white lines for coral elements2023-11-07T17:42:01+01:00

The Q&A and the rules set different rules regarding the white lines. For the international final, white lines will be considered as part of the area. Objects count as completely in, when they touch the white lines.

Will the waste in front of the fence score points?2023-02-13T16:57:45+01:00

The question is if a waste object scored like in the photo would score full points.
The answer is: Yes. However, it is very unlikely to place the waste object as this place without moving the fence (which results in less bonus points). Therefore it does make sense to put the waste behind the fence.

Does the white line belong to the reef area?2023-02-13T16:55:02+01:00

INTERNATIONAL FINAL: Clarification regarding white lines for server objects2023-11-07T17:40:45+01:00

The Q&A and the rules set different rules regarding the white lines. For the international final, white lines will be considered as part of the area. Objects count as completely in, when they touch the white lines.

Is the server object completely in if the loop is not? (Updated 20th of June 2023)2023-06-20T11:11:45+02:00

Full points for a server object are awarded if it is completely inside the correct connection slot. Completely is defined by: ““Completely” means that the game object is only touching the corresponding area (not including the black lines).”
Addition: The rules explicitly say “black lines”, because in the past lines were mostly black. Nevertheless this applies to all lines around areas, that are relevant to score points.

If an object only touches the correct area and other parts of the object (in this case the loop) is in the air (and not touching anything), full points will be awarded. One example for such a situation can be seen in the following photo (where the loop is not touching the mat).

If there are several game objects on one connection slot, points will only be awarded for one of them.
If a task object is on several connection slots at the same time, points are only awarded for one connection slot.
If two different scores could be given for a situation, the higher points will be awarded.

Scoring of Solar Panel – what counts?2023-03-16T07:51:59+01:00

The deciding factor to get points for the solar panel is the fact that the panel itself (the white plates) are up.
It is not important if the lever is pulled partly or completely.
In the following photos, full points for the situation in the middle and right photo are given.

Addition and Clarification to rule 6.22 (free parts)2023-09-15T16:25:24+02:00

If a robot loses parts on the own half of the game field, these parts are considered as free parts. Free parts will be removed from the field by the judges as soon as possible. If the robots of the causing team are disturbed by the free parts or the judges (during removal), this will be ignored – the match continues. Any balls that are delivered to the opposing team’s game field by the free part will be put back on the game field of the team that created the free part.

In addition:
If a robot loses parts on the opposite half of the game field, the match is stopped and the causing team loses.
