This document outlines the rules for the Mega Sumo robot competition.
One operator and four helpers can be registered for each robot (maximum 5 team members in total). However, only one operator and one helper may guide the robot during the match. The area where matches take place is called the Dohyo.
Both contestants who are called to the Dohyo for the match accept the competition rules and winning conditions, and must participate using only autonomous robots that they have built and/or programmed themselves.
The robots are placed on the Dohyo simultaneously at the referee's command. Competitors step away from the robots, and the referee starts the match via infrared (IR) remote control. The robot that manages to push its opponent off the Dohyo wins a round. The robot that wins two rounds is declared the winner of the match.
The competition format is determined by the organizers according to the number of participants. If participation is high, subgroups are formed. In group stages, robots are divided into groups of 3, 4, or 5. One or two robots with the highest scores advance to the next round.
Re-matching is performed among robots advancing to the next rounds and continues until at most 8 robots remain. Subsequent stages may be organized either as a points league or knockout:
Fibonacci International Robot Olympiad Mega Sumo competitions take care to classify and grade by taking into account education level and age groups. It can be divided into 2 basic groups: high school (16-18) and university (18+). The age group and education level of the team is determined by the age or education level of the oldest member of the team. It is the responsibility of the team mentor to ensure that teams are registered in the correct age category.
The competitions will be held on a round wooden field with a diameter of 154cm, called "Dohyo". The field is painted with a 144cm black circle in the center and the remaining area white. The white line on the outside of the Dohyo is called Tawara and is 5cm wide in white color. The area in the middle of the dohyo is matte black. The starting lines in the middle of the Dohyo, called Shikiri-Sen, are used to determine the starting positions of the robots and are painted in a dark color. Try to place the dohyo so that it is 10cm above the ground.
| Class | Height | Diameter | Material |
|---|---|---|---|
| Mega Sumo 3kg | 5-10cm | 154cm | Wood/MDF |
Robots can initially be placed in the user's desired position, with one side at the Tawara area (white edge line) and one side at the starting line. The robot must at least partially touch the Tawara area (white line). Once the robot is placed, it can no longer be moved. In cases where the winning robot cannot be determined, such as a draw, the referee may request that the robots start in a different starting position.
Mega Sumo robots must have a maximum width and length of 20cm (200mm) and a maximum weight of 3kg. There is no height limit, but the width and length values of the robots at every height must comply with this rule.
| Class | Weight | Length | Width | Height |
|---|---|---|---|---|
| Mega Sumo | 3kg | 20cm | 20cm | No Limits |
Robots cannot be divided, cannot leave or throw away any part of themselves during the competition. Competitors must fix the parts of their robots in a way that they cannot fall, batteries falling, screws coming out, blades breaking, etc. In such cases, the weight of the falling parts will be checked. Pieces weighing 50g or more will cause the contestant to lose the round.
Robots can change shape (expand) during the competition.
Robots cannot contain equipment (e.g. flashing lights, mirrors) that will affect or blind the opponent's sensors. Robots cannot use nets, ropes, or similar mechanisms to prevent the opponent robot from working.
Robots must use the starting module or equivalent circuits to detect the infrared starting signal sent by the referee. The contestant is responsible for any problems that may arise in robots that do not have a proper starting module.
The blades on the robots must be in a way that will not harm the rival contestant or the robot. During the competition control phase, the referees will make the necessary checks to ensure that the blades on the robots are not too sharp. However, if the robot damages the structure of the dohyo or significantly spoils the paint of the dohyo, it will be eliminated from the competition. The referee decides whether the robot violates this rule or not.
Competitors must adjust their robot's sensors to detect objects at a distance of 154cm, which is the maximum diameter of the dohyo. Robots that detect any person or object farther away than this value and turn towards it and throw themselves out before their opponent will be deemed to have lost that round.
Competitors must be in the competition area, ready for the competition, within 3 minutes after the names of their robots are announced. Otherwise, the match will start and the side that does not show up will start to lose their preparation time.
After the match starts, the parties are given 2 minutes of preparation time. At the end of the preparation period, both parties must be present with their robots next to the dohyo where the competition will be held. The side that is not in the competition area at the end of the preparation period is eliminated from the competition.
Parties have the right to one five-minute technical break for each match. The party taking a technical timeout may intervene in the structure of their robot. During the technical break, an assistant of the contestant can enter the competition area with their belongings.
The referee decides how the lineup will be in each round. After the preparation period is over, the referee explains to the parties how the robots will line up. As the referee counts down, the parties simultaneously place their robots on the Dohyo.
After the parties place their robots on the Dohyo, they are given 30 seconds to adjust their tactics without moving their robots. After this period, no intervention with the robots is allowed.
In the competition, if one of the robots does not move at all physically, and the other robot moves but falls on its own, there is a 10-second waiting period. If the robot that is not moving physically does not move within 10 seconds, the round is awarded to the robot that moved.
Each round can last a maximum of 60 seconds. If neither robot wins within this time, the referee stops the match and the round is repeated.
The round ends with one robot touching the ground. The first robot to touch the ground is considered defeated.
In competitions, if the competition continues with points, 3 rounds are played in any case. If the competition is in elimination mode and a robot wins the first 2 rounds, the 3rd round will not be played.
The juries' decisions are final and not subject to subsequent review. If a solution cannot be reached with the juries, objections must be submitted immediately to the Fibonacci International Robot Olympiad Chief Referee. Complaints made after this point will not be accepted.
Competitors cannot raise objections due to field factors after the round has started. These factors are eliminated by the referees with warnings made before the round.
The competitor may make a verbal objection to the referee for the result of a round after that round. When the next round begins, the contestant loses his right to verbal objection.
Competitors who do not comply with the referees' warnings or disrupt the course of the competition will be disqualified.
Fibonacci robot competition reserves the right to make any changes it deems necessary in the rules.
Robots must be checked by the referees before the tournament and labeled with number tags (Robot Number / Team IDs). These stickers are provided by the competition organizers. The sticker cannot be placed on the robot or any other component that could interfere with the operation of the opponent's sensors.
Changes and cancellations in the specifications are made by the main organizer of the competition in accordance with the regulations of the competition organizing committee.
| Class | Gloves | Glasses | Additional Safety |
|---|---|---|---|
| Mega Sumo | Heavy Duty Required | Safety Goggles Required | Protective Clothing Recommended |
During the competitions, competitors are required to wear protective gloves and safety goggles. Due to the larger size and weight of Mega Sumo robots, additional protective equipment is strongly recommended.
Competitors will not be allowed into the competition area with any electronic device (e.g. phone, tablet, RF remote control).
Interfering with robots without stopping the match is extremely dangerous. Competitors who intervene despite this will be disqualified.
Robots with swollen batteries or leaked fluids cannot be raced. If dangerous situations such as short-circuiting or smoke are detected in a robot during the competition, the competition will be stopped and the robot will be disqualified.
Mega Sumo Category is more dangerous than other categories due to the size, weight, and speeds the robots reach, and the cutting elements they may contain. Competitors must work carefully and take the necessary precautions at every stage of the competition. Despite this, Fibonacci International Robot Olympiad Organizers disclaim all liability for any material damage or injury that may occur.
