⚠️ 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 Athletes is to accurately hit a series of objects with a self-made gun that shoots nerf foam bullets.
-
The Sport requires precision, mechanics and correct calculations.
👥 TEAM – COACH
-
Participation in the competition is team-based, not individual.
-
Each team may consist of two (2) to three (3) members.
-
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. ➤ In other words, they cannot occupy an additional spot. If a team fails to comply with this rule, it will be disqualified.
-
The team is allowed to change the designated Technician before each attempt on the track, to give all members the opportunity to be actively involved in the sport, although this is not mandatory.
-
All team members must be at least 10 years old (equivalent to 4th grade of primary school or above).
-
The team’s coach must be at least 20 years old.
-
To ensure smooth participation in the competition, the coach must have 1 assistant for every 3 teams they register in the competition.
-
Each team is allowed to have only one robot. Changing the robot during the competition is not allowed.
-
Teams are not allowed to share the same robot.
-
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.

-
During the initial inspection, the team will be asked questions about the critical parts of the Gun'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 Gun examination based on the specifications described above.
➤ If the Gun 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 Gun 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.
-
It is mandatory for the Gun Technician to wear safety glasses. Protective equipment is mandatory on the playing field before and during matches. The protective equipment will be checked during the technical inspection.
-
The lack of protective equipment in whole or in part will be reason for the team to be disqualified from the Sport.

🏆COMPETITION
⏱️ PREPARATION
-
The Gun's Technician takes a position on the track in front of the red square.
-
The Technician's hand should not extend beyond the red square or wooden base. He can also rest his elbow on the base.
🏁 START - PROCESS OF THE RACE
-
The referee places the target box at the first distance (1.20 m).
-
The gun technician arms the gun and aims at any one of the three targets.
-
The technician pulls the trigger; a beep must be heard and the foam dart must be launched.
-
If the target is successfully hit, the points for that target are awarded.
-
The weapon is re-armed by the technician and aimed at a second target; the trigger is pulled (beep + launch).
-
If hit, those points are added to the running total.
-
The procedure is repeated for the third target; its points are added, and the referee records the total for the 1.20 m distance.
-
No specific order of targets is required (first/second/third is at the technician’s discretion).
-
The referee moves the target box to the second distance (1.60 m).
-
Repeat steps 2–7 for the 1.60 m distance; the referee records that total.
-
The referee enters the points into the scoring system, which sums the totals from both distances.
🔁 ROUNDS – ATTEMPTS - COMPETITION PROCEDURE
-
During the match there will be a time of 2 hours.
-
During this time each Technician will make repeated attempts on the track based on the order announced by the organizing committee.
-
If a Technician is not in line, they lose their attempt and the next Technician takes their turn. The Technician who lost the attempt must wait until all other attempts are completed for their turn to come again.
-
The referee records the points for each attempt.
-
The guns will pass a technical check by the assistant referee before each attempt.
-
No restarts allowed.
-
The team may change the designated Technician before each attempt (optional, to involve more team members).
-
The highest score achieved by a team across all its attempts counts as the team’s official score and determines the winner (best-attempt scoring).
❌ END OF AN ATTEMPT
-
When the Technician completes the effort at both distances.
-
If the Gun encounters a technical problem.
-
If the Technician during an attempt proves to be unable to aim in a straight line and this poses a danger to him, the referee or the participants on the playing field.
-
When the allocated time window for the attempt expires (as defined by the schedule/referee).
-
Upon any safety violation (e.g., pointing outside the target zone, crossing safety lines), at the referee’s discretion.
-
Upon unauthorized physical intervention with the Gun/targets/field after the attempt has started (beyond the defined procedure).
-
If the Gun becomes immobilized and cannot continue the procedure within a reasonable time, as determined by the referee.
-
If the Gun leaves the designated firing area or crosses a safety boundary.
-
If any projectile leaves the field of play or enters a spectator/official area (immediate stop for safety).
-
If the team fails to follow referee instructions or the defined competition procedure.
-
If the referee issues a stop command for any reason (e.g., safety, venue issues, force majeure).
🟥 TEAM DISQUALIFICATION
A team is disqualified from the event and must withdraw in the following cases:
➤ The team’s results will not be taken into account and will not appear in the official competition rankings.
-
If a Gun does not comply with the specifications defined in the sport’s rules and the team refuses to make the required adjustments.
-
If any of the Technicians behave inappropriately or disrespectfully, use offensive language, provoke, or verbally (or otherwise) attack fellow participants or referees.
-
If it is discovered that a Gun is not operating autonomously, but instead is being remotely controlled via Bluetooth, Wi-Fi, or any similar technology.
✅ ALLOWED / ❌ PROHIBITED
✅ Allowed:
• The use of common tires of independent diameter and independent thickness. But be careful you must not build a weapon that aims like a bow!!!. In this case your weapon will not pass the technical inspection.
❌ Prohibited:
• The use of accessories that can harm the spectators, referees or even their coaches.
• The use of propellants or any other material to increase force.
• Breaking the Gun into pieces or expanding it in any way during the match.
• Remote control.
• The use of pneumatics.
• The use of metal springs.
• The use of lasers to improve the mark.
• Modifying the Nerf dart in any way. If there is any doubt about a team's balls the referees will give the team balls during the match. The team will not use their own for obvious reasons.
🏆WINNERS
The 3 winners for each age category are those with the highest total score of both distances.
The best score is used to determine placement in:
🥇 1st place
