Combat robot (454 g) rules
1Description
The discipline involves battles between remote-controlled robots in a controlled environment. The goal of the competition is to defeat the opponent’s robot by pushing it out of the battle area.
2Competition rules
- 2.1A participant may only operate one robot per competition.
- 2.2For technical inspection and during the competition (upon the referee’s request), robots must be presented in an open state, allowing all components to be visible.
- 2.3Battles between robots must not exceed 3 minutes.
- 2.4Each robot battle consists of one round.
- 2.5If there are pits on the field, touching the bottom of a pit results in the robot losing the battle, except in the case of a multi-robot*.
- 2.6If a robot stops on the field or becomes uncontrollable, the referee may allow 10 seconds to regain control of the robot. Without regaining control, the robot loses the battle.
- 2.7At any point during a battle, the robot’s operator may choose to forfeit. In such a case, the battle is considered lost.
- 2.8If robots become entangled during a battle, the referee may require them to disengage, giving them 5 seconds. If the opponents do not back away from each other, the battle will be paused and the robots will be returned to their starting positions. The battle will then be resumed.
- 2.9If it is established that a robot was not switched on but had already collided with the opponent’s robot, the battle may be stopped and repeated, if the referee so decides.
- 2.10If no winner can be determined during a battle, the referee decides subjectively by their own criteria - for example, the most interesting, the most aggressive, the most active, etc.
- 2.11If it seems to the referee that the result of a battle will be a draw, the referee may end the battle early without waiting for the maximum time allowed.
- 2.12The robot must be placed in the battle area and be ready to fight at the time specified by the competition organizer, from the moment it has been called to the battle. Otherwise the battle is lost.
- 2.13After the battle ends, only the robot operator or the referee may remove the robot from the field. It is the operator’s responsibility to ensure that their robot is in a safe state before lifting it. If the robot has active combat tools, they must be turned off after the battle.
- 2.14If the referee suspects cheating, they are entitled to inspect the participant’s robot (by opening it). Refusal of this inspection or the discovery of cheating will result in disqualification.
- 2.15The referee’s decision or the result may only be contested at the end of the specific attempt. Complaints will not be considered afterwards. Once a dispute is resolved, the referee’s decision cannot be changed.
3Robot
- 3.1The robot’s maximum size and weight:
Length (cm) Width (cm) Height (cm) Weight (g) 20 20 Unlimited 454 Table 1. Robot’s maximum parameters - 3.2Outside the arena, all sharp edges must be covered with a protective shield.
- 3.3Robot limitations:
- Electronics and wires necessary for operation. Wires and electronic boards must not be used as a weapon or as protection against a weapon. The voltage in any part of the circuit must not exceed 24V.
- It must be possible to disconnect the power with a switch, without additional tools (pulling out a connector does not count).
- All sharp edges outside the arena must be covered with a protective shield.
- Efforts must be made to build the robot safe. If the referee considers the robot too unsafe for itself or others, it may be disqualified.
- Permitted remote control frequencies: 5.8 GHz, 2.4 GHz, 868 MHz and 433 MHz.
- Robots consisting of physically separate independently controllable parts are called multi-robots. As long as any part of the robot is still capable of movement, has not become stuck and has not fallen into a pit, the robot can be considered “alive.”
- 3.4Prohibited to use as a weapon:
- Weapons that cause invisible damage.
- Liquids.
- Adhesives and sticky weapons.
- Ropes and entangling-type weapons.
- Heat and flame weapons.
- Explosive weapons.
- Magnetic / induction weapons.
- Pneumatic weapons.
- Projectile / ammunition weapons that detach from the robot.
4Arena
- 4.1The minimum area is 2 m².
- 4.2In undefined places, pits of various shapes may be placed with a small barrier in front; a robot getting into a pit is considered a loss.
- 4.3Various other traps or moving objects that can damage the robot may also be placed in the arena.
