Line Follower Classic
These rules may not be the final ones, the organizers have the right to modify them as they see fit. If there are any changes we'll let you know at once.
1. The goal of the challenge
The robot has to follow a track marked with a line. The robot must follow the line at all times. The whole robot must start behind the starting mark and is considered to have crossed the finishing line if any part of the robot crosses it when the robot has completed a full lap of the course.
2. Requirements of the robot
A. The robot has to be autonomous (no external control mechanisms are allowed)
B. The robot may be altered during the competition as long as it is still compliant to the rules. All physical change of the robot must be reported to the jury for approval. Alteration of software does not need to be reported.
C. The jury has the right to inspect that the robot is compliant to the rules at any time.
3. The Arena
3.1 The arena has white surface and a black line. The line may either be painted or taped.
3.2 Characteristics of the line course
A. The line is 2 x 5.6m and about 2 cm wide.
B. No segments of the line is closer to another segment than 15 cm (measured from the center of the line segments)
C. The arena edge is never closer to the line than 15 cm (measured from the center of the line).
D. The curve radius is at least 7.5 cm.
A. The robot’s maximum dimensions are 30x30 cm and the maximum weight is 3kg.
B. B. The teams that cannot prove the functionality of the robot in the given conditions are disqualified.
5. The competition
Time shall be measured by an electronic gate system or by a judge with a stopwatch, based on the availability of the equipment. Either case, the recorded time shall be final. The final classification will be made using the best time for each robot.
5.2 Autonomous Control
Once a robot has crossed the starting line it must remain fully autonomous, or it will be disqualified.
You are not allowed to touch the robot, except the case when the robot exits from the competition area and it must be stopped.
5.3 The Course
A. After placing the robot behind the start line, the robot is activated upon the referee signal.
B. The time starts when some part of the robot crosses the start line the first time and stops when some part of the robot crosses the start line the second time after completing a full lap.
C. The robot must have contact with the surface at all times.
D. The robot has to follow the line at all times. A robot is considered to be following the line if any part of the robot overlaps the line. If the robot deviates from the line (no part of the robot overlaps the line), the attempt is considered failed.
5.4 Calibration stage
It will be held in the day before the competition and in the competition day after check-in until the competition starts.
5.5 How the challenge takes place
Each robot has 3 attempts (one attempt per round), each attempt has maximum 3 minutes.
An attempt is valid if the robot is able to make 2 complete laps, starting from the start point set by the judge, and in the given direction (which is the same for all the robots), without leaving the line or having any external help (the actions of turning the robot on and off are, of course, allowed).
The arena is cleaned by the organizers at the end of each round or at the demand of the participants.
For the rankings, only the times set in the valid attempts are used.
The ranking is made according to the smallest time (the shorter time period used, the higher the ranking).
