WRO 2019: Regular Category Elementary

Transportation is a fast-growing and changing industry in the 21th century. One part of automation in transport is self-driving cars. A self-driving car is able to sense the environment and navigate without human input. Since 2015, Hungary has been actively involved in the development of self-driving vehicles and in the near future, a modern test track will be finished and ready to start testing advanced technology in a road environment.

This year, it is the mission to build a robot that can act as a real autonomous, self-driving taxi that takes passengers from a starting position to a target area.

The map layout for the elementary category

This year’s WRO maps are noticeably more colourful and enhanced, presumably to follow the style of the First Lego League map designs.

Game Objects

There are 8 coloured passengers (green, red, yellow, blue), 4 adults and 4 children, and 2 white passengers, 1 adult and 1 child, on the field. Note that not all passengers are used in one run.

There are two battery blocks on the field as well.

There are two walls on the field. Movement or destruction of walls is not allowed.

Positioning of Game Objects/Randomisation

Position of the passengers are randomised at the start of each round. The randomisation is done in the following steps:

1. Place all coloured passengers

2. Draw four colours one by one and change figures accordingly:

• Replace the child of the first drawn colour with the white child

• Replace the adult of the second drawn colour with the white adult

• Remove the child and adult of the third and fourth drawn colour respectively

One battery block is placed in the Start & Finish Area. The battery block can be placed on the robot before the start. The other battery block is placed in the small position in the black area.

Walls are placed on the dark grey areas that are exactly the same size of each wall. One wall surrounds the home area. The other wall is between the shopping centre and cinema area.

Robot Missions

a) Bring the passengers to their target areas

The robot should bring the yellow, green, red and white passengers to their target areas:

Yellow passengers

• Bring to the yellow area ( Cinema Area)

Green passengers

• Bring to the green area (Zoo Area)

Red passengers

• Bring to the red area (Shopping Centre Area)

White passengers

• Bring to the white area (Home Area)Blue passengers

• will stay in the zoo the whole day

• should not be moved

For the scoring, only the coloured area (not including the black line)  counts.

b) Bring the equipment to the charging station

One of the battery blocks should be brought to the marked Battery Area inside the charging station. Points are rewarded if the battery block is completely inside the Batery Area.

Only one battery block counts (the one with the highest points).

c) Park the robot

The robot must be entirely inside the Start & Finish Area when the round is complete.

d) Penalty points (walls)

Walls cannot be damaged or moved from the grey area. A penalty is given if walls are damaged or moved from the grey area.
