Information on how to use these game rules in countries:
We deliberately have a mix of simple and more difficult tasks in the game rules. These rules
are also used for the WRO International Final, where we expect to see many teams thatcan solve all missions. At a local, regional or national level however, there will be many
teams that do not have the experience, knowledge or time to solve everything. This isintentional. By offering simple and more complicated tasks all teams will be able to solve
parts of the challenge and can keep trying to improve their work. (Also see chapter 6)

1. Introduction
Life underwater is important and humans depend on it for food, clean drinking water and evenfor protection against flooding. That is why it is important that we protect the water against
pollution and that we protect and restore the underwater eco-systems.
To protect our oceans, we have the “MARPOL convention.” It is an agreement between
countries worldwide that ships cannot pollute the water and throw their waste overboard. Thismeans that ships will need to save all their waste until it can be collected.
There are also many initiatives that help to restore underwater areas. One of the mostimportant is the protection and restauration of coral reefs. Many other underwater animals findfood and protection there and these reefs also reduce the risk to coastlines from flooding.
But the coral reefs are damaged in many places. Researchers are working hard on finding
ways to restore the coral reefs. One solution is growing corals in an aquarium and then bringing
them to the existing reef.
On the Elementary game field, the robot will help managing ship waste, restore coralareas and rescue a whale from a shallow area in the sea.

2. Game Field
The following graphic shows the game field with the different areas.

If the table is larger than the game mat, place the two sides of the start area against the walls.
For more information about the table and game mat specifications, please take a lookat WRO RoboMission General Rules, chapter 6.

3. Game Objects, Positioning, Randomization
Waste (4x, 2 times in ship hatch)
In every round there are four waste objects on the field:- The green waste object is always placed in the ship hatch on the green ship
- The yellow waste object is always place in the ship hatch on the yellow ship
- Two of four other waste objects are randomly selected in each round, they areplaced on the ship of their colour.

Waste objects(one red, one black, one white, one blue)

Ship hatch(one with green, one with yellow waste)

Start position of waste(on a ship, always in this orientation withthe long side parallel to the wall.
Possible ships:
red, black, white and blue)

Start position of waste in ship hatch(on yellow and green ship, inside the hatch- the waste is always placed to the front)

Please note, that the ship hatches on the yellow and green ship are fixed on the field (seeGeneral Rules, chapter 6).

Coral (4x)The four corals are always placed on the little yellow areas on the field. They are placed exactly
on the yellow and blue markings following the bricks of the model.

Start position of object on the field
Coral (4)Whale (1x)There is one whale on the field. The whale is randomly placed in each round on one of thewhite circles on the field. The whale is always placed looking in the direction of the little arrowon the game field, see the following photos.

Fence (2x)
Two fences are placed in front of the yellow and green recycling areas.

Start position of the fences
Fence (2)

Summary randomization
On this field, the following objects are randomly placed in each round:••

Two waste objects on ships that are not the green or yellow ship
The whale on one of the white circles

One possible randomization you can see here: green X for the whale, red X for waste
objects (here on blue and red.)
You will also see the red X on the yellow & green ship, where there is always a waste object.

4. Robot Missions
For greater clarity, the missions will be explained in multiple sections. The team candecide which parts of the missions they will do and in which order. Final scoring will bebased on the situation on the field at the end of the run.

4.1 Manage Ship Waste
The robot should bring the waste from the ships to the recycling areas on the game field,
therefore, the robot needs to collect the waste from the ships. Collecting the waste from theyellow and green ship is a bit more difficult and the teams will get more points for that.
Full points are awarded if the waste is in the corresponding-coloured recycling area (e.g. thegreen waste in the green recycling area).

4.2 Rescue the Whale
A whale has been spotted in one of the coral reefs. The sea is shallow there and it is not thebest place for this big animal. It might be lost. There is a whale watching area in the open
ocean where people can see these animals in their natural environment. The robot should
bring the whale from the coral reefs to the whale watching area in the open ocean.
Full points are awarded if the projection of the whale is completely inside the whale watchingarea. The whale watching area is defined by the dark blue line in the top-left corner. The dark
blue line itself does not belong to the whale watching area. It is not allowed to damage thewhale game object.

4.3 Restore the Coral Reefs
The life under water is important for our overall eco-system. That is why we want to restore
the coral reefs. In these areas the corals and other marine life are all part of an eco-system.
They depend on each other for food and shelter. The robot should bring the new coral to thecoral reefs next to it.
Full points are awarded if the coral is completely inside one coral reef (the rectangle squarenear the coral start position). Maximum one coral per coral reef counts.

4.4 Get bonus points
Bonus points will be awarded for not moving or damaging the fences. A fence is moved if at
least one pillar of the fence is no longer touching the grey circle where it is placed at the
beginning.

4.5 Park the robot
The mission is complete when the robot returns to the Start & Finish area, stops, and the
projection of the robot is partly (top-view) within the Start & Finish area.

5. Scoring
Definitions for the scoring“Completely” means that the game object is only touching the corresponding area (notincluding the black lines).
Please note that there is a new rule about damaged game objects in the RoboMission
General Rules (Rule 6.8).

6. Local, regional, and international events
WRO competitions take place in around 90 countries, and we know that teams in each country
expect a different level of complexity. The challenge as described in this document will be
used for international WRO events. This is the last stage of the competition, where the teams
with the best solutions participate. That is why the game rules are challenging.
WRO feels that all participants need to be able to have a good experience in the competition.
Teams with less experience should also be able to score points and succeed. This builds
confidence in their ability to master technical skills, which is important for their future choices
in education.
We deliberately have a mix of simple and more difficult tasks in the game rules. This meansthat all teams will be able to solve parts of the challenge and can keep trying to improve theirwork.
WRO Association recommend that our National Organizers consider the situation in
their country. They can adapt the rules for events in their country even further. They
can decide to make the challenges easier for local, regional, and national events, sothat all participants have a positive experience.
All National Organizers can make their own choices, so each competition fits their
specific situation and ideas. Here we provide some ideas to make the challenges easier.

Ideas for simplifications:•••Have a fixed position of the whale (communicated before or selected at the start ofthe competition day
Have two fixed colours of the waste objects that are placed on the mat(communicated before or selected at the start of the competition day)Take out one or both fences (in this case adjust the scoring for bonus points)
