Competitions and rules

Below follows the rules for the competitions held during Swedish Robotics Champotionship, as well as some Frequently asked questions

The rules where last updated 2015-02-18. The changes made for each competition is summarized in the beginning of each document.

Swedish Robotics Championship consists of the following competitions:


In this competition the robots try keep themselves in the ring for as long as possible. Important factors are power, speed and a good sense of surroundings. There are several classes, from the largest standard class down the smallest pico class. During Swedish Robotics Championship, competitions in all classes where there is an interest will be held. This applies primarily to Standard, Mini and Micro. New from 2015 is Lego-sumo.

Rules for Sumo, all classes[pdf]

A corollary to these rules is the specification for the remote start system. This applies to standard-, mini-, micro- and nano sumo robots. They are found using the following link (external page):

In this competition the robots compete in trying to follow a line the fastest. Here, speed and control are the primary challanges.

Rules for Linefollowing, (simple and advanced)[pdf]



The goal of Folkrace is that the robots shall drive around a walled course. In this competition, multiple robots compete at the same time, so it is important to be able to tell what is a robot and what is a wall.

In 2014, some bigger changes of the competition format have been made. Make sure the rules carefully.

In Freestyle Excibition, any robot can compete, no matter size, appearance or function. Only your imagination sets the limits. The robots will be judged in categories such as hardware, intelligens and usefulness.

General about the competiton

  1. Are there any problems with being sponsored by a company? In that case, are there any limits to what can be sponsored.

    Answer: No, there are no problems and there are no restrictions concerning being sponsored by a company.

  2. Does a change of battery count as modification of hardware?

    Answer: We don’t have any clear guidelines for what counts as change of hardware and what doesn’t. That assessment is normally done at the competition from case to case. If you would like to have an assessment on before-hand, please send us pictures/videos on what you want to change. Concerning the specific case of battery change, this is OK, as long as the new robot still complies with the rules.

  3. Are there any limits to the computing capacity of the robot or what can you build your robot with within the physical limits of rules?

    Answer: No, there is no such limit, as long as all computation is done on the robot and that the restrictions for size and weight are met.


  1. Is the robot allowed to “lift” the opponent out of the dohyo?

    Answer: Yes, this is allowed. But remember that the robot may not harm the other robot the dohyo.Ja, detta är fullt tillåtet. Men kom ihåg att du inte får skada den andra roboten eller planen.

  2. Concerning jamming signals, does this also apply to lamps and LEDs?

    Answer: If the purpose of your signals is to jam the opponents sensors (i.e. with lamps radiating string IR-light with the purpose of saturating the opponents sensors) it’s not allowed. Most bulbs etc. are included in this. It is however allowed to use normal LEDs on the robot to, i.e. signal the status of the robot.

  3. Must the robot have with the dohyo at all times?

    Answer: No, it doesn’t. The robot must however not fly actively. This does not mean that the robot automatically loses if it happens to jump, but it may not be built for flying.


  1. Will there be any sharp corners?

    Answer: No, because a sharp corner would have a radius less than 7.5 cm (which is not allowed).
