Line Follower Turbo

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 robot has to follow a black line marked on a white surface.
    2. For the final ranking, only the best time of the 3 valid attempts will be taken into consideration.

    1. The robot has to be autonomous (no external control mechanisms are allowed) and must not be dangerous;
    2. The robot may be altered during the competition as long as it is still compliant to the rules. All physical changes of the robot must be reported to the jury for approval. Alteration of the software does not need to be reported;
    3. The jury has the right to inspect that the robot is compliant to the rules at any time.
    4. The robot must not be leaking any substances or destroy the track in any way;
    5. EDF (electric ducted fan) or assimilated systems are allowed.
    6. The teams shall provide easily accessible and visible area of 2x2 cm designed for noninvasive marking of the robot with the purpose if internally identifying the robot during the event. Each competing robot shall undergo homologation (detailed below) and after successful homologation shall be identified.

    1. The arena has white surface and a black line. The line may either be painted or taped.
    2. Characteristics of the line course:
      1. The width of the line is between 16 and 18 mm;
      2. The lines of two adjacent curves should not be closer than 15 cm;
      3. The minimum distance between the edge of the playing area and the edge of the line is 15 cm;
      4. The curve radius is at least 7.5 cm;
      5. There will be crossovers (e.g. places where the line crosses itself);
      6. A ceiling will be present; the robot will climb on it via a "C" with diameter of 1.9m. The line is continued on the loop and after it.

    1. The robot’s maximum dimensions are 30x30 cm and the maximum weight is 3kg;
    2. Visual inspection is performed for ruling out remote control systems.

    1. Timekeeping
      1. 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.
    2. Autonomous Control
      1. Unless the judges allow it, any external interaction with the robot leads to a failed attempt.
    3. The Course
      1. After placing the robot behind the start line, it is activated upon the signal of the judge;
      2. 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;
      3. The robot must have contact with the surface at all times;
      4. Trespassing the marked area by the team members or objects connected to team members is forbidden.
      5. Any manipulation of the robot (including by not limited to touching, poking, pushing, repositioning) is forbidden during an attempt of the challenge;
      6. 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.
    4. Practice attempts
      1. Will be held starting the day before the competition (after registration) and in the competition day until 1 hour before the challenge starts.
    5. Calibration stage
      1. It will be held in the day before the competition and in the competition day after check-in until the competition starts.
    6. How the challenge takes place
      1. Each robot has 3 attempts (one attempt per round), each attempt has maximum 3 minutes;
      2. The robot must follow the line at all times. It is considered to have crossed the finishing line if any part of the robot crosses it;
      3. 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).
    7. Cleaning
      1. The arena is cleaned by the organizers at the end of each round or at the demand of the participants, between the attempts.
