Line Follower Drag Race


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 track marked with a black line on a white surface;
    2. The robot will have to be capable of following a straight line as fast as possible.
    3. 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 after starting the robot, which can be done using a remote control) and must not be dangerous;
    2. The robot may be altered between stages of the challenge 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. Robots will compete in pairs on identical parallel tracks.
    3. The robot with the fastest time out of three rounds will win.
    4. Track characteristics :
      1. There shall NOT be crossovers (e.g. places where the line crosses itself)
      2. The line will be straight without interruptions or curves
      3. The stop line will be market by a intersecting perpendicular line to the main line
      4. The closest approach of the line course to the edges of the arena shall be no less than 15 cm, measured from the center of the line.
    1. The robot’s maximum dimensions are 30(Width)x30(Length) cm and the maximum weight is 3kg;
    2. Visual inspection is performed for ruling out remote control systems.
    1. Timekeeping
    2. 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.Autonomous Control
      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 the track;
      3. The robot must have contact with the surface at all times;
      4. 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
      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
      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 maximum 1 minute to finish the track. The robots will compete in a tournament style ranking, the fastest robot out of 3 rounds wins the match. The time for the whole Drag Race contest is given according to the number of the participant.
      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. Trespassing the marked area by the team members or objects connected to team members is forbidden.
      4. Any manipulation of the robot (including by not limited to touching, poking, pushing, repositioning) is forbidden during an attempt of the challenge;
      5. Time for each robot is measured from the moment of the line passing until the finish line passing. It is considered that the robot passed the finish line when the farthest point of it pass the line. The time is measured using an electronic gate.
    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.
