1.1. Autonomy

The robot must be fully autonomous, with one exception: one verified start stop module is allowed as long as it is controlled by the referee. The robot must be completely autonomous after passing the Start Line; if it is not, it will be disqualified.

1.2. Size and Weight Limits

The maximum size of a robot is 30 x39 cm, the maximum weight is 3 kg. Dimensional and weight limits for robots shall be strictly enforced. Robots must have passed inspection prior to competing.

2. The Track

We consider Line Follower Classic the most basic level of the Line Follower Style robot competitions. This category is usually for beginners.

3. Technical   inspection

Before the competition, the robot must pass the technical inspection.

3.1. The maximum dimensions are 30x30cm and the maximum weight is 3kg.

3.2. The robot will have to be capable of making an entire lap around the track. For technical inspection the robot must complete one lap of the track.

3.3. The wheels of the robot and other parts that are in contact with the track must NOT be able to pick up and hold a standard paper A4 (80g/cm2) more than 2 seconds.

3.4. Final check of the homologation will consist of making an entire lap around the track with the robot, there will be 3 attempts allowed for this.

4. Time

4.1. Time measured on the track

Time for each robot is measured from the moment of passing the start line until passing the finish line. It is considered that the robot finishes when the farthest point of it passes the line. The time is measured using an electronic gate (or a judge with a stopwatch in some cases). The shortest time of each team is taken into account regardless of the number of tries. During the competition each team will be called by the referee according to registration order. The number of tries are limited only by the time allocated for the Line Follower Classic category.

4.2. Time Limit

Each robot has a 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. The category lasts around 3 hours (depending on the number of participants) with possibilities for extensions announced by the referee.

5. Penalties

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

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

6. Declaring Objections

6.1. No objections shall be declared against the judges' decisions.

6.2. The lead person of a team can present objections to the Committee, before the match is over, if there are any doubts in the exercising of these rules. If there are no Committee members present, the objection can be presented to the judge before the match is over.

7. Flexibility of Rules

As long as the concept and fundamentals of the rules are observed, these rules shall be flexible enough to encompass the changes in the number of players and of the contents of matches. Modifications or abolition of the rules can be made by the local event organizers as long as they are published prior to the event, and are consistently maintained throughout the event.


8.1. Participating teams are always responsible for the safety of their robots and are liable for any accidents caused by their team members or their robots.

8.2. The Robotics Championship organization and the organizing team members will never be held responsible nor liable for any incidents and / or accidents caused by participating teams or their equipment.
