Questions & Answers to Games & Rules

At this page we will publish frequently asked and important questions related to the WRO 2018 games. The answers on this page can be seen as additions to the rules and will be used as base for the WRO International Final. 

Please be aware that in your country local competitions may follow slightly different rules, contact your National Organizer for more information.

Q&A All categories

Yes, the official kit from this website is allowed as long as the participants can explain the use and functionalities of the blocks and functions they have created.

Q&A WeDo Regular

No, all rules that are important for WeDo are included in the WeDo Game Document. If information is not included in the document, it can be decided by the National Organizer. We want to keep this competition flexible and easy to adapt for all National Organizers. For example, the National Organizer can decide if the robot should be preassembled or not.

If the fruit falls of the robot it will be just as if the fruit is pushed of one of the fruit supporters and it will score in that way. (10 points)
The fruit will probably roll somewhere and that is ok.

If fruit happens to roll into a blue/red/green area it is allowed to pick it up manually.

If fruits happens to roll into the right area for scoring it will score 10 points.

Yes, when a robot is in a green area it may be placed in any of the other green areas manually.

Q&A Regular Category Junior

Any plants can be placed into the green area. Please see the scoring table for different options to score points in all areas.

The orientation of the walls is explained the Regular Category Junior Game Document, page 4: "The walls have to be placed in front of the farm to protect the fields of the three farms." The walls are not symmetrical, so there is only one option to position them.

The numbering is explained on page 5 / 6. In addition, please see this graphic for clarification.

The rules say that the green line is not included at the start, but is included at the finish. This is a bit confusing.

We have decided that the green line is not included at both start and finish.

Q&A Regular Category Senior

Each ship can only transport one food brick.
If there are more food bricks in a ship only one brick will score points. This will be the brick that scores the highest amount of points.

The original rules say that 4 containers are placed on the field randomly. And then after that the color that is not used in the game should be removed again. This can be a bit confusing.
Of course you can also select 3 random colors at the beginning and then place the 3 containers of that color randomly on the field.

At the beginning of each round the 3 temperature controllers will be placed in the Factory Area. (Only 3 are placed because in each round 1 color is not used.) They are placed in the little area with the same color (e.g. red temperature controller on the red place).

The food containers should be placed with the 2 open slots facing the start area.

The temperature controllers are placed with the loophole facing the long sides of the playfield.

To clarify one possible setup, please take a look at this graphic.

The rules say that the green line is not included at the start, but is included at the finish. This is a bit confusing.

We have decided that the green line is not included at both start and finish.

The description of the finish of the robot can be confusing. The rules say that the chassis of the robot should be in the finish area.
What is meant is that the projection of the robot should be within the finish area. Here is an example.

Q&A Advanced Robotics Challenge

The 3rd to 5th randomly selected tetracubes must be placed on the field. (rule 3.a.) They are not allowed to touch each other. They should be at least 100mm apart from each other, just like they should be at least 100mm away from the borders.

The 6th randomly selected tetracube will be placed on the stackingform by the judge. (rule 3.c.) This tetracube should remain in its original position. It cannot be moved, turned, or taken away from the frame.

If the robot does move this tetracube to another position, or turns it into a different orientation or takes it away from the frame the run will be invalid.

Note: If the tetracube is touched by the robot placing other tetracubes and moves a bit in result it will still score points. But it should stay in the same position ("column and row") on the stacking frame it was originally placed at.

Teams that are planning to use supportive/other controllers should adhere to the following:

The main controller must be the MyRio or the KNR,  on these controllers all decision making, manipulation of sensor data and control must take place.
Other controllers can be used in a supportive role, but only to provide a means of control to the main controller to drive motors. Supportive controllers can also be used to  provide a means of increasing the number of inputs and/or outputs to the main controller. The manipulation of the information sensed by the sensors should take place on the main controller and not on the supportive controller.

Teams that are using supportive controllers must provide information (access to source code, circuit diagrams, etc.) to the judges to prove that the supportive controllers are only used to drive motors or are used as a device to increase the number of inputs/outputs for use with sensors.
