1. Introduction
Green cities are urban areas that are designed to be more sustainable and environmentally friendly. They have several advantages that help to improve the quality of life for their residents and live more in harmony with nature. Some of the advantages of green cities are: Green cities have cleaner air, which is better for our health. .
 .
 Green cities have more parks and gardens, which are great places to play and explore. .
 Green cities use renewable energy, which is better for the environment. Examples of modern and transforming green cities are Singapore or Paris where more trees and green areas have been installed to transform the cities into a green city. 1 On the Junior game field, the robot will help transforming a city to a greener place by setting up new parks, helping people make a (roof top) garden and making use of renewable energy.
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 mat against the wall with the sides of the park A and the water area. 2

Park elements
There are 2 blue lake elements and 4 green elements (2 trees, 2 flowers) on the field. All elements are randomly placed on the green rectangles that are numbers 1- 6 on the bottom of the game field. Please note: The green elements are always placed in the front of the green marking on the field (because their base is 4x4) and the lake elements use the full space of the green marking (because their base is 4x6). The lake elements are always oriented so that the yellow beaks of the ducks point towards the centre of the game field. The flowers are oriented parallel to the border, with the higher leaf of the flowers pointing towards the start area © 2023 World Robot Olympiad Association Ltd.
Green Starter Kits
There are 3 green starter kits that are always placed on the yellow rectangles on the left side of the game field.
Electric Bikes (E-Bikes)
There are 2 e-bikes on the field that are placed in front of the charging area A on top- left of the game field. There are small black markings that fit the wheels of the e-bike.
Cable
There is one cable on the field that is always placed in the start area.
Houses
There are 3 houses, two apartment buildings and one family house. They are placed on the positions in the house areas in the middle of the game field. The family house in the middle will be fixed to the game mat. In addition, there is a little scoring helper object that is only used to score if the door of the family house is closed or not. It will not be on the field and may only be used by the judges.

It will not be on the field and may be used by the judges.
Fence
There are 3 fences that are placed around the two park areas. They are always placed on the same positions on the game field and are not allowed to be moved or damaged.

4.  Robot Missions
4.1 Create new green areas
The robot should help to create new green areas in the city. Two new parks (park A and park B) should be created. It is the task of the robot to bring: . One lake element to each park . Two green elements to each park (flower or tree element, does not matter which) The following table shows the scoring of this task and the photos show scoring situations apply for both the lake and green elements. Please note the following aspects for this task: . Maximum one lake element and two green elements count per park area (no matter if touching or completely in). Points for are only awarded if the elements still stand upright. .
 Definition “completely in”: Completely means that the game object is touching the corresponding area only.

4.2 Greening houses
The city government has decided that house owners can apply for green starter sets to create their own (roof top) garden. It is the task of the robot to bring: . One green starter set to each apartment house. . Additional points for a green starter set inside the family house. The following table shows the scoring of this task and the photos show scoring situations. Please note for this task: . Maximum one starter set per area counts. . A starter set is considered inside the house if it is behind the door and the door is closed. The door is considered closed if the door (including the grey door handle) is above the grey area in top-view. . Definition “completely in”: Completely means that the game object is touching the corresponding area only.

4.3 Electrical charging and connection
In the city, more renewable energy is used for transport and general electricity. It is the task of the robot to help by: . Bringing the electrical bikes to the charging area A. For that, the e-bikes need to be pushed into the charging area A. . Bringing the cable to the charging area B. The following table shows the scoring of this task and the photos scoring situations. Please note that “completely” means that the game object is only touching the corresponding area.

4.4 Bonus for fences & Apartment houses
It is not allowed to move (outside of light or dark grey areas) or damage the fences and houses. If those objects are not damaged and moved, you will always get bonus points. The following table shows the scoring of this task and the photos show scoring situations that apply for both the fences and the houses. Please note for this task: . Definition “damaged”: Any situation that means that the game object is not exactly like at the start of the run, e.g. a brick fell off. . Definition “moved”: The game object is considered as moved if a part of the game object is touching the mat outside of the grey area (light grey area for the fences, dark grey area for the houses).
