WRESTLING 1kg

⚠️ RULE ZERO – Zero Tolerance & Common Sense
In all sports, Rule ZERO applies, which states:

➤ "If you are not sure whether something is allowed, then it is probably NOT allowed."

All rules are based on common sense, the spirit of the sport, and the safety of all participants.

Any deliberate misinterpretation, violation of the meaning of the rules, or attempt to exploit gray areas for unfair advantage will not be tolerated and may lead to team disqualification from the competition.

​

🎯 GOAL

The goal of the Robot Athletes is to take the opponent out of the battle on the specially designed wrestling track and be considered the winner.

There is a time limit 1 minute in each match.

Wrestling, as a sport, does not require the injury or destruction of the opponent, but only his displacement off the track. This can only be done by pushing the opponent with the robot's main body, just like  two human wrestlers would fight.
In such a case the Robot Athlete who violates the core values will be excluded and the opponent will be declared the winner.

​

👥 TEAM – COACH

1. Participation in the competition is team-based, not individual.

2. Each team may consist of two (2) to three (3) members.

3. Each team must designate up to one (1) Robot Athlete Technician. Only the Robot Athlete Technician is allowed in the waiting area or competition area. The rest of the team must remain in the competition venue but cannot wait in line.            

4. The team is allowed to change the designated Technician before each attempt on the arena, to give all members the opportunity to be actively involved in the sport, although this is not mandatory.

5. All team members must be at least 10 years old (equivalent to 4th grade of primary school or above).

6. The team’s coach must be at least 20 years old.

7. To ensure smooth participation in the competition, the coach must have 1 assistant for every 3 teams they register in the competition.

8. Each team is allowed to have only one robot. Changing the robot during the competition is not allowed.                   

9. Teams are not allowed to share the same robot.

10. If a team encounters a serious technical issue with their robot, they are allowed to replace only the microcontroller or the electronic components, after obtaining permission from the Head Judges.

​

🤖 ROBOT ATHLETE – ROBOT CATEGORY
Eligible Robot Athletes include Basic and Advanced type robots.

The competition is conducted separately based on:

• Age category

• Robot type (Basic / Advanced)

​

⚙️ ROBOT ATHLETE REQUIREMENTS – SPECIFICATIONS​

1. The Robot Athlete must be autonomous.

2. The maximum dimensions must be 20 cm Width × 20 cm Length.

3. Weight: up to 1 kg.

4. The Robot Athlete will be weighed and must comfortably fit inside the control box.

5. The control box dimensions are 20 × 20 cm with a tolerance of two (2) millimeters.

6. The Robot Athlete must be placed inside the control box without applying pressure.

7. The Robot Athlete must not damage or wear down the track or pose any kind of threat to spectators.

8. The Robot Athlete must be equipped with a start and stop button.                                                                                               ➤In the Wrestling Advanced category, Athletes  should be equipped with MicroStart Module Jsumo.

9. For the  Basic  category, the following limitations apply: only one (1) microcontroller, four (4) motors, and four (4) sensors may be used.                                                                                                                                                                          ➤ For the Wrestling Advanced category the use of multiple microcontrollers and sensors is unrestricted.

10. Robot Athletes in the Wrestling Basic category are built exclusively from educational modular brick/beam kits (LEGO-like or equivalent, indicative examples LEGO® Education EV3/SPIKE/Robot Inventor, ZMROBO, MAKERZOID, ENJOY AI, Makeblock mBot, DFRobot Maqueen and similar) using the official hub/controller and the corresponding motors/sensors. All motor/sensor connections are made directly to the official hub, with official cables/parts of the kit; external microcontrollers, motor drivers/ESCs, non-official adapters/converters, or additional power sources/boosters are not permitted. Interoperability of official components of the same manufacturer is permitted when plug-compatible or via an official adapter (e.g., LEGO SPIKE motor on a LEGO Robot Inventor hub).  Robots that do not meet the above are placed in the Wrestling Advanced category.

11. The use of pneumatic devices/equipment is prohibited in any robot category.

12. In the Basic category, οnly the official batteries/power supplies provided with the educational kit allowed. Modified batteries, motors, and sensors are prohibited. 

13. The use of external batteries, boosters, converters, motor drivers, that increases the voltage beyond the nominal rating of the official hub is strictly prohibited. The nominal voltages of these hubs must be up to 9V.

14. For the Wrestling Advanced category any type of battery or power source may be used, with an upper limit of 24V nominal voltage in any circuit or part of the robot. The use of a nominal electrical voltage greater than twenty-four (24) volts is prohibited.

15. Pullback motors are strictly prohibited in any robot category, as the sport promotes engineering and experimentation to increase speed.

16. The use of gases (e.g., canisters or any equivalent) to increase speed and strength is prohibited, as they are considered dangerous.

​

🧱🛡️  3D Printed / Structural Parts – Shields & Extensions  NEW FOR BOTH CATEGORIES

• Robot Athletes are allowed to include 3D printed parts or other structural materials for protective shields and extensions at the front, rear, and/or sides.

• At the start of the match, the Robot Athlete must fit entirely inside the official control box (20 × 20 cm, tolerance ±2 mm).

• After the start, the Robot Athlete may expand forward, backward, and/or sideways, but the maximum overall dimensions must never exceed 30 × 30 × 30 cm when in full extension on all sides.

• Shields and extensions may be mechanical or deployable (e.g., lowered, expanded, or unfolded after the start).

• Shields and extensions must not be white in color, in order to avoid interference with arena line markings and sensors.

• The maximum weight limit of 1 kg remains in effect, including all shields, extensions, and additional parts.

• Extensions/Shields must be constructed only from plastic material.

• In the case of using flags, the use of paper and fabric of any color is permitted. The total height of the Robot Athlete with the flag in verical position must never exceed 25cm.

• All shields and extensions must be safe: no sharp edges, no dangerous parts, and no elements that damage or wear down the arena surface.

• If, after the start of the match, the referee determines that the Robot Athlete does not comply with the specifications stated in the rules, they have the right to disqualify the team from the event.

​

🧪 TECHNICAL INSPECTION

• The initial technical inspection takes place on the day of the competition, during the Robot Athlete’s first attempt.

• During the initial inspection, the team will be asked questions about the critical parts of the robot's program.
  ➤ The team must have their laptop with the robot’s program open.
  ➤ If it becomes clear from the answers that the team does not understand the program, they will receive a penalty equal to -20% of the score they achieve in the event.

• The technical inspection includes a robot examination based on the specifications described above.
  ➤ If the robot does not meet the requirements, it will not be allowed to compete and will be automatically disqualified from the event.

• After the completion of the initial inspection, the Robot Athlete is assigned its unique ID code.

• If a team is not present at the time of the initial technical inspection, it will result in automatic disqualification from the competition.

• A secondary technical inspection is also conducted before each attempt, performed by the assistant referee.

• If, during the competition procedure, the referee determines that a Robot Athlete is violating or failing to meet the prescribed specifications, the referee has the right to disqualify it immediately.
