Competition Field

Competition Field Specifications

• The size of the competition field is 1220mm x 2440mm. The base of the field is white and the black lines on the field have a width of 18-25mm. (For details, see photo).
• The size of the Start Box and the Finish Box is 250mm by 250mm.
• The size of the colour patch must not exceed 50mm by 50mm.
• The red box in the competition field represents 12 x 12 studs of LEGO® bricks in 2 layers.

Objective of the Game

To design an autonomous robot that can follow the track line from the Start Box and turn or cross at the intersection according to the traffic lights represented by the colour patches, to arrive at the specified position and push the 12 x 12 studs of LEGO® bricks in 2 layers into the Finish area.

Rules and Regulations of the Game

• The track line will be black, symbolizing the city roads. The width of each line is between 18-25mm, and the distance between the lines in either direction is approximately 200mm in length and 100mm in width.
• Adjacent to intersections, there will be numerous 50mm ×50mm rectangular patches or "Traffic Lights". The colour of the patches may vary; robots must recognise these patches and perform the actions listed in the table below.
• The robot must follow the track line, and at the intersection, the robot must act according to the commands of the "traffic light". Note that the robot should act according to the “traffic light” before an intersection, and ignore the “traffic light” after the intersection. When arriving at the colour patches before the intersections, the robot must do the following:



• Within the start position, any part of the robot must not cross the Start Box limits.
• The exact placement of the colour patches will be announced on the day of the competition before the quarantine and will be used throughout the tournament.
• The robot does not need to stop automatically at the Finish Box.
• Once the judge signals “incomplete game”, the team operator should stop the robot immediately.

Scoring System

• If the mission is completed within the time limit of 90 seconds, the team that is the fastest (with the shortest time taken) is the winner.
• In the event of failure to complete the mission, the scoring of the round will be decided by the last intersection with a colour patch that the robot passes through just before the robot misses the track.
• On passing each intersection with a colour patch the robot will earn 10 points.
• On pushing the 12 x 12 studs of LEGO® bricks in 2 Layers into the Finish Box, the robot will earn 15 points.
• The basic rule for scoring points is to obtain points sequentially. This means that a robot can only obtain points by passing through the intersections on the correct path and in the correct order.
• If the mission is completed, but exceeds 90 seconds, then the extra time taken will be subtracted from the final total score, with precision kept at 2 decimal places. (For example, if the time is 100 seconds, then 10 points will be subtracted from the total score)
• The maximum number of points that can be subtracted is 10 points.
• The best time from the two trials during the competition will be the final score.
• In the event of a tie, the robot with the lightest mass (excluding batteries) wins.
