Challenge rules

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

The robot has to follow a track marked with a black line.It has to be able to make decisions in regard to the course of the line and avoid the obstacles placed by the referees before the start of the race. 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. Rules for the robot

A. The robot must be completely autonomous after passing the Start Line; if it is not, it will be disqualified.

B. Before the competition, the robot must pass the Homologations.

3. Rules for the track

A. The track for the contest is a 2x5.5m area in white.

B. There will be crossovers (e.g. places where the line crosses itself)

C. Switchbacks and hairpins are possible, but the adjacent sections of the line shall not be closer than 15 cm to each other, when measured from the center of each line.
The closest approach of the line course to the edges of the arena shall not be less than 15 cm, measured from the center of the line.The minimal curve radius is 7.5 cm. Sharp angles may occur, but will not be smaller than 90°.

D. Interrupted line may occur.

E. An obstacle may be on the track, which the robot shall avoid. If the team considers, they can ask the judge to remove the obstacle but for a time penalty of 13 seconds.

4. HOMOLOGATION

A. The robot’s maximum dimensions are 30x30 cm and the maximum weight is 3 kg.

B. The teams that cannot prove the functionality of the robot in the given conditions are disqualified.

5. The competition

5.1 Time measured on the track

The time for each robot is measured from the moment when the start line is passed until the moment when the finish line is passed. It is considered that the robot passed the finish line when the farthest point of it pass the line. The time is measured by using an electronic gate.

5.2 Time limit

Each robot has maximum 3 minutes to finish the track by trial. The robot can do an unlimited number of trials in the time given by the organizer. The time for the whole contest is given according to the number of participants.

5.3 Timekeeping

The time for a robot is measured by an electronic gate or a judge with a stopwatch, based on the availability of the equipment.

5.4 Losing the line

If a robot loses the line it must restart the trial. If it loses the line for the second time, it will receive 3 minutes for that trial. Trials can be restarted just as many times as wanted in 3 minutes.

If the robot loses the line but it is able to come back on the track from the point where he lost the line, it can continue on the track with 3 seconds penalization.

5.5 Ranking

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).
