Line Following — Official Rules

1. Introduction

This document outlines the rules for the "Line Follower" robot competition.

2. Description of the Competition

Line follower robot competitions are exciting and educational events that test the ability of autonomous robots to move as quickly as possible on a track drawn with black lines on a white background. One operator and four helpers can be registered for each robot (there can be a maximum of 5 team members in total). However, only one operator is allowed to guide the robot during the encounter.

The robot is expected to follow the line in the direction indicated by the referee and complete the track. The robot is placed at the starting point determined by the referee. During the placement period, competitors are given time for robot calibration. After the robot passes the sensor level, the stopwatch starts to run. When the robot passes in front of the sensor again, the stopwatch stops and the time for the robot to complete the track is determined in this way.

Each team has the right to compete in 3 rounds. Times are recorded for 3 laps and the lowest time is considered as the team's track completion time. The winning robot is announced by the referees.

2.1. Fixture

The competition format is determined by the tournament organizers depending on the number of participants. Teams have 3 rounds of 3 minutes each to complete the competition. After all teams participating in the competition complete their 1st Round qualifications, the 2nd and 3rd rounds are held respectively.

2.2. Classification and Rating

Fibonacci International Robot Olympiad Line Follower competitions take care to classify and grade by taking into account education level and age groups. It can be divided into 5 basic groups: kindergarten (0-6), primary school (6-10), secondary school (10-14), high school (14-18) and university (18+). The age group and education level of the team is determined by the age or education level of the oldest member of the team.

3. Competition Field Description

The track consists of a black line (15-20mm width) on a white background. The track includes various challenges such as straight sections, curves, crossings, and obstacles. The total track length varies between 3-8 meters depending on the age category.

3.1. Track Features

• Straight Lines: Various lengths for speed testing
• Curves: 90° and 45° turns with specified minimum radius
• Crossings: T-junctions and intersections
• Obstacles: Small ramps or barriers (advanced categories only)

3.2. Starting and Finish Areas

The starting area is marked with a clear line perpendicular to the track. The finish line uses the same marking system. Timing sensors are placed at both locations to accurately measure completion times.

4. Robot Specifications

4.1. Size and Weight Limitations

Robots must comply with the following dimensional constraints:

4.2. Sensor Requirements

Robots must use appropriate line detection sensors. Common sensors include:

• Optical Sensors: Infrared reflectance sensors
• Camera Vision: Computer vision systems (advanced categories)
• Color Sensors: RGB sensors for line detection

4.3. Autonomous Operation

All robots must operate autonomously. Remote control during the race is strictly forbidden. Robots may have calibration modes that can be activated before the race starts.

4.4. Safety Requirements

• No sharp edges or dangerous components
• Secure battery mounting to prevent ejection
• Emergency stop capability (recommended)
• Wheels must not damage the track surface

5. Competition Rules

5.1. Race Format

Each team has 3 attempts to complete the track. The best (fastest) time among the 3 attempts will be used for final ranking. Each attempt has a maximum time limit of 3 minutes.

5.2. Timing System

Official timing is done using electronic sensors. Manual timing may be used as backup. Time starts when the robot crosses the start line and stops when it crosses the finish line.

5.3. Penalties

• Line Loss: 5-second penalty for each time the robot completely loses the line for more than 3 seconds
• Restart: 10-second penalty if the robot needs to be manually repositioned
• Track Damage: Disqualification if the robot damages the track

5.4. Disqualification Conditions

• Robot exceeds dimensional or weight limits
• Use of remote control during the race
• Robot causes damage to track or equipment
• Unsportsmanlike behavior from team members

5.5. Technical Issues

If technical issues occur due to track conditions or equipment failure, teams may request a re-run. The referee's decision on technical issues is final.

6. Judging and Scoring

6.1. Primary Ranking

Teams are ranked by their best completion time (including penalties). Faster times rank higher.

6.2. Tie Breaking

In case of identical times:

1. Second best time comparison
2. Third best time comparison
3. Fewest penalties
4. Additional run-off race

6.3. DNF (Did Not Finish)

Teams that cannot complete the track within the time limit receive a DNF status and are ranked below all teams that finished.

7. Awards and Recognition

Awards are given for:

• 1st Place: Fastest completion time
• 2nd Place: Second fastest time
• 3rd Place: Third fastest time
• Best Design: Most innovative robot design
• Best Newcomer: Best performance by first-time participant

8. Safety and Conduct

8.1. Safety Measures

All participants must follow safety guidelines:

• Proper handling of electronic equipment
• Safe battery practices
• Respect for competition equipment

8.2. Code of Conduct

Participants must demonstrate good sportsmanship and respect for officials, other teams, and equipment. Violations may result in warnings or disqualification.
