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 manyteams 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)※ このルールブックは，WRO 2023 RoboMission Juniorのルールをもとに，WRO

1. Introduction
After the invention of the telegraph, it was suddenly possible to send long distance messages
in a much faster way than ever before but sending a telegraph requires cables and, initially,sending a message to overseas still needed to be done by boat. This changed when the firsttelegraph cable was laid on the bottom of the sea between England and France in 1850. Plans
were made soon to install a cable that would cross the full Atlantic Ocean. After many setbacks
the submarine cables became a great success, and more were installed all over the world.
You might think that submarine cables are no longer necessary, with modern day satellites
and Wi-Fi, but they are still crucial for communication, and they are the backbone of theinternet. Modern fiber-optic cables can transmit data much faster than satellite connections.
Sending a signal across the Atlantic Ocean by cable is around eight times faster than sending
it by satellite*. A place where submarine cables interconnect with each other is called asubmarine cable hub. Panama is one of these hubs, where cables from the Caribbean Seaand Pacific Oceans connect. Underwater vessels and robots can help maintaining thisinfrastructure and help with new technical solutions at sea such as offshore solar farms andeven submarine data centres.

On the Junior game field, the robot will help to install and repair submarine cables,install submarine server farms, and activate offshore solar panels.

Marking blocks (1x white, 1x black)
The marking blocks are placed in the ship information centre. They are used to determine theplacement where the robot should bring the server objects (black marking blocks) andsubmarine cables (white marking blocks).. One white and one black marking block are
randomly placed on the little areas marked 1.- 4. on the Caribbean 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 Underwater deployment
The robot should help to install underwater infrastructure for the world-wide internet data
network. For that, the robot should transport the submarine cables and server objects from theshipyard to the connection slots.
The connection slots are determined by the marking blocks in the ship information centres for
the Caribbean side, for example: a white marking block on Caribbean no. 4 and a black
marking block is placed on Carribian no. 1 means that a submarine cable should be placed inthe connection slot no. 4 and the server object on connection slot no. 1.
Full points are awarded if an object is completely inside one connection slot.

4.2 Bonus points
Bonus points will be awarded for not moving or damaging the barriers on the field.

4.3 Park the robot
The mission is complete when the robot returns to the Start & Finish area, stops, and theprojection 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 beused 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 choicesin 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. Theycan 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 the randomization only for one part (Pacific or Caribbean).
Have no randomization and place the marking blocks always in the same positionin the ship information centres.
Have a fixed position for the red cable in one of the connection slots.
Take out one or both barriers (in this case adjust the scoring for bonus points)
