1. Introduction
The forces of nature are powerful and unpredictable. We need to be prepared for the possibility of major disasters in many places in the world where people live. We need to develop new technologies and strategies to help us mitigate the effects of these disasters and to rebuild our communities after they occur. Robots are an example of one of these new technologies. They can help to warn us in advance for a coming disaster. They can also help us to prevent excess damage from and to help with rescues and rebuilding after a disaster has hit. On the Senior game field, the robot will help restoring a city after a natural disaster. The robot will rebuild houses, clean the streets from debris and will repair water pipes.
2.  Game Field
The following graphic shows the game field with the different areas. If the table is larger than the game mat, centre the mat in all directions.

Randomization of the start area
There are two start areas on the game field. On the day of competition, one start area is s selected for the full day. Teams will then start from this area and the placements of some house elements (see next) will align with that.
House elements
There are 16 house elements (4 red, 4 yellow, 4 blue, 4 green) on the field: 4 red and 4 yellow house elements will always be placed next to the two - different start areas - 4 blue and 4 green house elements will be randomized and placed on the different positions on the field: 2 elements top-left, 2 top-right, 2 bottom-right and 2 elements next to the start area of the competition day World Robot Olympiad and the WRO logo are trademarks of the World Robot Olympiad Association Ltd. © 2024 World Robot Olympiad Association Ltd.
Debris elements
There are 4 debris elements (2 yellow, 2 dark grey) on the field. They are always placed on the orange and grey rectangles on the game field.
Water Pipes
There are 2 water pipes on the game field. The different parts are always placed on the blue circles on the field, all elements will be fixed to the mat.
Obstacles
There are 16 individual 2x4 LEGO bricks (8 red, 8 yellow) that are fixed on the game mat as obstacles for the robot.
Bridge
There is a bridge on the way to the top-left corner. The bridge is always placed with the lower side looking to the start area and will be fixed on the mat.
Barriers
There are 3 barriers on the game field (2 surrounding the top-left corner, one on the right side of the game field). All barriers should not be to be moved or damaged. © 2024 World Robot Olympiad Association Ltd.
4. Robot Missions
4.1 Rebuild houses
The robot should help rebuilding houses after an earthquake in the city: - 4 houses – one in each colour (red, yellow, green, blue) – should be built in the different coloured areas on the field (e.g. red house in red area). - Every house can have four floors. Maximum points are awarded if all four houses are built with 4 house elements of the colour matching the colour of the area below. For the scoring of the house elements please note the following: - The lowest element (floor 1) must always be completely inside a coloured house area and the colour of the lowest floor element must match the colour of the area, otherwise no points are awarded for the entire house. Completely means that the game object is only touching the coloured area. - All house elements must always be stacked with the studs facing upwards. House elements cannot be upside down or on the side. - House elements stacked on the 1st element can only be supported by the element below it. They cannot be supported by anything else, like the floor or another element. - Only one house per coloured area counts. If there are two houses in an area that could score points, then the house with the most points will be scored. The following table shows the scoring of this task and the photos show scoring situations that apply for all kind of coloured houses.

World Robot Olympiad and the WRO logo are trademarks of the World Robot Olympiad Association Ltd. © 2024 World Robot Olympiad Association Ltd. are completely built (4 floors) and placed in the correct coloured area. 3x14=42 points (the house in the blue area do not score points because the lowest element is not matching the color)
4.2 Clean Debris
In the city, some debris is lying around and the robot should help collecting it. Full points are awarded if the debris is touching the collection area in the bottom-left of the game field. The following table shows the scoring of this task and the photos show scoring situations that apply for all kind of debris elements.

4.3 Repairing water pipes
The water pipes in the city are not functioning anymore and the robot should repair the pipes. Full points are awarded if one part of the water pipe was tilted to the other and with that, the water pipe is reconnected. The following table shows the scoring of this task and the photo show the scoring situation for this task.

4.4 Bonus for barriers
Barriers should not be moved outside of the white surrounding area and should not be damaged. If those objects are not damaged and not moved (outside of the white surrounding area), you will always get the bonus points. The following table shows the scoring of this task and the photos show scoring situations that apply for all of barriers.
In case a game object is damaged, please see the RoboMission General Rule 6.8. World Robot Olympiad and the WRO logo are trademarks of the World Robot Olympiad Association Ltd. © 2024 World Robot Olympiad Association Ltd.
