RoboTEC 2019 contest: General Rules of the Competition

The purpose and the objectives of RoboTEC 2019 contest:

The purpose of RoboTEC Contest is to promote science and engineering among high-school and university students with technical backgrounds, on one side, and the general public on the other side.

The main objective of the contest is to involve high-school and university students in creating autonomous robots.

The second objective is to bring together, in Timișoara, participants from all over the world who are passionate about robotics and to create a favorable context for them to disseminate the projects they are involved into.

For each challenge there will be groups of maximum three students. Each team is allowed to have a coordinator/mentor who will guide them throughout the entire period of the project.

An individual can’t be part of two different teams applying for the same contest category.


The surface on which the competition will take place differs from one challenge to another, the details being specified in the rules of the respective challenge.

Regardless of the challenge, it is assumed that the teams are already prepared for varied illuminated environment and also for the reflection factor of the surface. There will be no appeal regarding the reflection level on the surface on which the challenge will take place or the illumination of the environment.

The audience is allowed to use flash light cameras in order to take pictures, as well as focusing cameras with infrared, except the case in which the referee considers that using them might influence the behavior of the robots.

It is recommended for the robot to have modulated or filtered sensors, not to be influenced by ambient light, reflectors or flashes of digital cameras - Organizers do not assume any liability for malfunctioning robots due to environmental light (ambient, flash lamp, IR lamp for recording cameras).


Depending on the challenge, there might be some restrictions regarding the robots. They are specified, for each challenge, in the corresponding rules section.

Regardless of the challenge, the robots can’t put someone’s life in danger. If the referee considers that the robot can’t function in safety conditions , it will be disqualified.

Each registered robot must be designed and built by the team members - using robots purchased from the market is strictly forbidden. For building the robot, the team can use already manufactured components, only if they don’t represent the solution to the given problem and if the team has designed the interaction mode and has assembled them.

For example, using some pre-manufactured sensors for line following robots is allowed.


Before the beginning of the contest, a representative person from each team will present the robot to the referee for homologation. If a team will not pass this stage, they will be disqualified.

Regardless of the challenge, the referee will make sure that the rules are respected by the team. After checking the robot, the referee will make sure that it was truly build by the team members - he can ask questions regarding the design of the robot and the way the robot was programmed.

Depending on the challenge, new stages of homologation can be introduced - some of them are specified in the rules description of each challenge.

If it passes the homologation, the robot will be placed by the team leader on the referees table. Until the end of the challenge, the team will be able to retrieve the robot only for participating into the challenge or for different adjustments. Of course, it is forbidden any adjustment that results in violation of the rules (e.g. exceeding the maximum weight limit after being weighed is, of course, forbidden).


For each challenge, the first three places will be awarded with diplomas and rewards. Depending on the number of registered teams, we will award them with diplomas. In exceptional cases (e.g. solving a mechanical or an electrical problem in an ingenious way) the referee committee can propose awarding the team with a special prizes and diplomas.


It is considered misconduct if the participants violate the provisions of sections 6.1 or 6.2 and they will be sanctioned.

6.1 Insults:

If a participant addresses to the opponents or referees insulting words, or there is a robot with audio devices mounted to address insulting words or writing offensive words and gestures on the robot body, it may be penalized.

6.2 Offences:

When the contestant enters the area of the conducting tests, except where the referee stops the meeting.

Part of the competitor's body is on the playing area during the tests.

If foreign objects are placed on the playing surfaces without the referee’s knowledge.

If a team asks a test route without a good reason.

Do not comply with the referee’s decisions.


Each deviation accumulates. At 3 misconducts the team / participant is disqualified from the competition for the current edition.


For each event there will be 3 or 5 referees. The decisions shall be final and irrevocable. Referees may make an exception from the regulation where appropriate, with the obligation to announce the participants about the modification they made.

The referees have the power to take decisions currently not covered by the Regulation if they facilitate game play.

Any complaints will be made to the project coordinator or to the logistics responsible, NOT TO THE ORGANISERS.


The rules are flexible in the measure to allow adjustment to the number of participants and games. Modification or cancellation of rules can be decided by the local organizer of the event, as long as they are published before the event and are maintained throughout the event.


A. The participating teams are always responsible for the safety of their robots and they are responsible for any accident caused by team members or robots.

B. Liga AC and the organization team will never be responsible for incidents / accidents caused by participating teams and their robots.


The general rules of the competition as well as the challenges rules organized inside RoboTEC competition may be modified with a previous announcement. In order to be easy to identify, the modifications brought to the regulation between two consecutive versions of it, are documented briefly in the version description.



The kill switch is used to cut the power of the robot motors. This is used as a safety precaution and it is only mandatory in the Mega Sumo class. When the referee sends the stop command, the power to the motors has to be cut. The robot builder is responsible for adding such a kill switch on the robot, however the prebuilt module can supply the signal for activating the kill switch.


The prebuilt module takes care of all the communication and it is very easy to implement. The robot only needs to wait for the start pin on the module to go high and then it should start. The module accepts supply voltage (VCC) 3.3 - 5V. The VCC GND Start has a standard of 2.54 mm pitch. The prebuilt module can be ordered from the organizer, having a surcharge, during the online registration.


The figure below illustrates the modes of operation of the module. To be less sensitive to noise and disturbances, the module will save its current state into a non - volatile memory and if it resets, it will return to the last known state. This means that each match will end with the referee sending the stop command.

If the LED on the module is “on” before the referee has sent the start command, it means that the module is in the “Started” state. Then, the stop command has to be sent and the robot needs to restart for the module to go back to the “Power ON” state. To be able to run multiple matches next to each other, each dohyo will have its own unique identifier. The prebuilt module can be re-programmed to listen to a new identifier. This is done by the referee, by sending a special programming command which updates this identifier.

The Home Mode

The module has an option of usage without the special remote control. On the back of the module there are two large pads- Home and GND. If one of them attaches an 1 Kohm resistance between the two pads, the module will accept signal from a standard TV remote control (the remote control that uses RC-5 coding and was developed by Philips, but there are many other companies that use the same protocol). Sony and Nec have their own protocol and the remote control will not work. The best way to test if the remote control works, is to test it with the module. Pressing the 1 button from the TV remote control will be START and 2 will be STOP.
