This is an unofficial translation of the rules. The only official version of the rules in cases of misunderstanding is the Slovak version.



The competition task

To build a autonomous mobile robot, which will travel the whole defined path in a certain time. The direction and course is defined by the dark line, also some obstacles are presented.

Topic of the year 2015: World is not just black and white.

The path

The background of the path will be white with dark (black) navigation line on it (width 15 +/- 1 mm). Total length of the path won't be more than 20 meters. Material used will be a chipboard.

The smallest radius of curves used in the path will be 5 cm Total rising of the path won't exceed 3 cm; maximal rising or declining is 5%. Like in the real life, there can be random obstacles in the path (interrupted navigation line, obstacle on the line, illumination changes and other).

The robot's task is not to find the right way, just to follow the navigation line.

The robot starts within the starting area, which is 30 cm before the start line (infrared beam of the time measuring device). When the beam is interrupted by any part of the robot, the time starts to be measured.

The time measurement is stopped when the similar beam of light located at the end of the path is interrupted.

There are no barriers at the edge of the contest area. On the each side of the dark line will be the 15 cm wide safety area. Nevertheless, it is recommended to implement the safety device to avoid the fall from the edge. Organizers can not guarantee that area around the arena will be open. Hence the authors used to carefully evaluate the sensor measurements, especially near the arena edges.


Robot operation

There must not be any interference between the robot and its team after the robot is set in the starting circle and turned on. The robot must be controlled only by its electronics.

The robot may not leave the line after crossing the starting line. Avoiding obstacles is the only one exception. While moving, the robot may not leave any marks or beacons on the table. No parts can remain on the path during the run.

The competitor is disqualified when the competition path is damaged.

Dimensions and size of the robot

The width and height of the robot cannot exceed 20 cm. Length of the robot is not limited. Please, notify the limits given by tunnels and circle radiuses during the run.

Minimal dimensions and weight are not limited.

The competition and the order of the competitors

The competitors must be prepared to the start within 1 minute after the call. Every robot has total 3 runs to compete. But if the competitor does not present within 1 minute after the call, the run is lost. The time between the runs can be used for fixing and adjusting the robot. In the case of too many competitors, the jury can decrease the number of runs, or it can proclaim a qualifying round.

Time limits

The robot has 3 minutes to complete the path. After 3 minutes, the time measurement is stopped and the run is canceled. But the robot is not disqualified. The time stop has no affect on the next runs.

Evaluation and prices

Topic of the year 2015: World is not just black and white.

In the 2015 the contest will be simillar to the previous one. Robot has to travel all the track, turn at the end and safely return home. The point, where the robots decides to return determines the level at which the robot is evaluated:

The winner is the robot with the shortest time from any of the three runs. Second and third place will not be evaluated. If the smallest part of the robot enters the next level, robot will be evaluated in it. It cannot be evaluated in lower level. Unfinished run will not be evaluated.

The jury can also award the robot with the best design or interesting construction.

And, of course, all the common rules apply.
