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
Our modern-day society relies on container shipments that transport all kinds of goods over
the oceans. In the past, particular routes would involve ships having to take long, dangerous
journeys around the edges of continents, such as around Cape Horn in South America or Capeof Good Hope in Africa. But the construction of the Panama Canal and the Suez Canal havemade it possible for ships to reach their destinations much faster and more safely. Manymodern transport ships have even been built exactly according to the Panamax or the new
Neopanamax standard: the maximum size for crossing the Panama Canal.
Standardization and automation are other aspects that have made international transport oversea more effective. The introduction of standard shipping containers is an example of thisstandardization. These containers can easily be transferred from a ship to a truck or a train,
making transportation faster. In modern ports many processes are automated, for example,
unloading of containerships and even piloting of ships. Even autonomous ships are a thingthat we can expect to see in the near future.
On the Senior game field, the robot will help to load and unload ships, fuel them andpilot them to open sea.

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

If the table is larger than the game mat, put the side with the container depots and the ship
information centre towards the wall.
For more information about the table and game mat specifications, please take a lookat WRO RoboMission General Rules, chapter 6.

Crane A and B
There are two cranes on the field. Both cranes are constructed in the same way andpositioned in the same way on the game field. Please note that the cranes need to be fixed
on the field (see General Rules, chapter 6). Make sure that, as well as fixing the crane to themat, you also fix the mat directly to the table underneath the game object for more stability.

WRO 2023 – RoboMission – SeniorMarking blocks (4x)There are four marking blocks (2x green, 2x blue). Two marking blocks are randomly selected
and then placed on the positions 1 and 2 in the ship information centre. The other ones won’t
be on the game field. The marking blocks indicate two containers that should be loaded on the
big ship.

All marking blocks

One possible placement of two marking
blocks in the ship information centre

Harbour walls (4x)There are four harbour walls on the field that divide the field into the harbour and outer sea
area, these barriers are not allowed to be moved or damaged. The part with the lighthouse isalways placed towards the middle of the game field.

Harbour walls (2x)Placement of the harbour walls at the
beginning of each round (one black walland one lighthouse element should beplaced on the marked harbour wall area oneach side)

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 Load the small ship
The robot should help to load containers on the ships in the harbour. On the small ship therobot can place two containers to get points. It is not important which colour the containers
have (green, blue and/or white).
Points are awarded for each container that is loaded onto the ship. Additional points areawarded if the loading is completed (two containers are on the ship). It does not matter whereon the ship the containers are placed. It is allowed that the robot moves the ship to make theloading easier or faster. The ship itself should not be damaged, but it is OK if the flag, flagpole
and/or blue round brick holding the flagpole are damaged or fall off.

4.2 Fuel the big ship
Robots do not only help with loading containers on the ships, but they can also help withmaintaining ship vessels. A task of the autonomous robot vessel in this harbour is to fuel the
big ship.
For this, the little fuel brick (2x2 yellow brick) should be added to the ship. It can either be on
the ship or in the ship (e.g. in the little triangle at the front touching the mat). To fuel the ship,
the robot can activate the fuel station and get the fuel brick itself. The robot can also push the
big ship into the fuel station. Then the fuel station is activated and the little fuel brick falls into
the ship.

4.3 Load the big ship
Loading the big ship is a bit more complicated than loading the small ship. For a complete
loading three containers must be loaded on the big ship:••

Always one white container
The other two containers of the colour defined by the marking blocks in the ship
information centre, example: If a green and blue marking block is placed in the ship
information centre, a green and a blue container should be loaded onto the big ship.

Points are awarded for each container that is loaded onto the ship. Additional points areawarded if the loading is completed (all three containers are on the ship). It does not matter
where on the ship the containers are placed. It is allowed that the robot moves the ship tomake loading easier or faster. The ship itself should not be damaged, but it is OK if the flag,
flagpole and/or blue round brick holding the flagpole are damaged or fall off.
For points in this task it does not matter what happens with the special container (see 4.4).

WRO 2023 – RoboMission – Senior

4.4 Unload the special container
At the beginning of each round, there is one special container (the red one) already loaded on
the big ship. It is the task of the robot to help unload this container with the help of a crane.
For this, the robot could either fetch the container from the big ship and transport it to a craneor push the ship in front of one of the cranes and unload the container automatically.
Points are awarded for different end situations. You get points if the robot holds the container,
more points if the container is at crane A and even more points if the container is at crane B.
Additional points are awarded if the crane with the container is activated, and the container islifted.

4.5 Escort the ships to open sea
Once containers are loaded onto the ships, the autonomous robot vessel should pilot the ships
out of the harbour to the open sea.
For that, the robot should push or pull the ships across the dotted dark blue line between the
harbour walls that differentiates the harbour area from the open sea. Points are awarded if theships have completely crossed the line on top-view but points are only awarded if at least one
container is loaded onto each ship.

4.6 Bonus points
Bonus points will be awarded for not moving or damaging the harbour walls on the field.

4.7 Moor the robot vessel
At the end, the autonomous robot vessel should be moored. This, the team can do by either
ending in the Start & Finish area or by ending in the mooring station at the open sea.
In both cases, it is OK if the robot is partly within (top-view) one of these areas.

Scoring Interpretation
Definition for all containers in all mission:“On/Onto the ship” means that a container is only touching the corresponding ship andno other parts of the robot or the game mat. To score points it does not matter how or
where the container is positioned on the ship. You can see the examples in the firstmission for the small ship, the interpretation is the same for the big ship.

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:•••

No randomization of the containers in container depot A
Take out one element of both harbour walls (in this case adjust the scoring forbonus points)
Decide that it is ok that the red container is always brought to crane A (then delete
the points for the option to bring it to crane B
