ANTweight

1.    Weight restrictions

1.1. Robots may weigh a maximum of 150 grams (see 1.2 & 1.3 for exceptions).

1.2. “Shuffle robots” that do not use wheels, tracks, rollers, or other rolling mechanisms for movement may weigh up to 225 grams.

1.3. Full-fledged “Walker-Bots” whose leg trajectory is not circular with constant angular velocity (e.g., a servo with a simple servo arm is not considered a regular walking mechanism) may weigh up to 300 grams. The stride length must be at least 1.5 times greater than its height.

1.4. Robots consisting of multiple parts (Clusterbots) are allowed. However, all parts must comply with the weight restrictions when added together. If a clusterbot consists of robots with both rolling and non-rolling movement mechanisms, the following formulas apply:
Weight of rolling robots = 150 – (2/3 * Total weight of non-rolling robots)
Weight of non-rolling robots = 1.5 * (150 – Total weight of rolling robots)

2.    Size restrictions

2.1.       Robots of all weight restrictions must fit entirely within a 15 x 15 cm square area, without exceeding any height restrictions. There is no height limit.
2.2.      When measuring clusterbots, all parts must be placed within the square at the same time.
2.3.       Robots must start the match in the same orientation in which they passed the size check.
2.4.      Robots may extend beyond the permitted size limits only after the start of the fight, and only if the extension is activated by remote control (i.e., not by pre-tensioning or spontaneously).

3.    Power sources

3.1.      Batteries and accumulators must not contain free-flowing acids/electrolytes that could leak.
3.2.       The maximum permitted voltage is 24 V.
3.3.       Battery charging must not be left unattended and must be carried out near non-flammable containers and ideally in charging bags – LiPo bags.

4.    Weapons

4.1.      The following types of weapons are prohibited:

      • Weapons that use a stream of liquid that could escape the robot
      • Nets, ropes, adhesives, and other weapons that cause entanglement
      • Electronic weapons (jammers, lasers, electric shocks, etc.)
      • Magnetic and induction weapons
      • Explosives or other explosive weapons
      • Free-flying projectiles
      • Thermal weapons
      • Any device designed to distract or interfere with the driver (high-brightness LEDs, loud speakers, etc.)

4.2.      The organizer has the right to decide on the eligibility of a robot’s weapon and, if necessary, prohibit it from participating in the tournament. If you suspect that a weapon may violate the rules or safety regulations, please contact the organizer before the tournament to be on the safe side.
4.3.       The maximum allowable pressure for gases (e.g., tires) is 7 bar.
4.4.        MThe maximum allowable pressure for liquids (e.g., hydraulics) is 15 bar.
4.5.       Weapons must not be intentionally detached from the robot. However, weapons/projectiles attached by a cable are permitted if the distance between the center of the robot and the tip of the projectile does not exceed 500 mm. These projectiles must be properly attached to the robot.
4.6.        Thermal weapons (soldering iron, flamethrower, etc.) may be permitted depending on the venue, subject to approval by the organizer. organizátorem.
4.7.       All sharp weapons and edges that pose a risk of cutting or stabbing must be covered outside the arena.
4.8.      All active weapons must be remotely controllable and have the option of deactivation.

5.    Safety

5.1.       Each robot must have a failsafe setting – after the remote control is turned off or the signal is lost, the robot must stop all movement, including the weapon.
5.2.      Robots must have an externally accessible way to turn them off (e.g., a switch, toggle switch, removable connector, or battery connector). All switches and similar elements must have clearly marked on/off positions.
5.3.       Rotating weapons must be secured when the robot is turned on, and only after verifying that the robot is functioning properly can the safety be released. Before turning off the robot after a match, the weapon must first be secured and only then can it be turned off.
5.4.      All matches must take place in the arena, regardless of the type of weapon used by the robots. The arena doors must always be closed before the start of the fight.

6.    Matches

6.1.      Before the start of the competition, each robot will be inspected by the event organizer to ensure that it complies with the rules. Only then will it be allowed to compete. The weight, dimensions, switch, failsafe, securing of rotating weapons, and sharp edges are checked. Random checks may be carried out before any match to verify compliance with the rules, without having to give a reason.
6.2.       A match lasts 3 minutes as standard, but may end earlier, see situations specified in points 6.3 – 6.7. If no winner is determined during the standard time, the match ends in a draw. If it is necessary to decide on a winner (e.g., elimination matches), the evaluation of the match is handed over to 3 pre-selected judges.

They make their decisions based on the following criteria:

    • Weapon effectiveness – whether the weapon was used and what damage it caused
    • Aggressiveness– whether the robot actively engaged or tended to evade
    • Control over the opponent – who overpowered whom and prevented movement

6.3.      A robot that falls out of the arena and touches the bottom of the pit loses. If it bounces off the wall of the pit back into the arena without touching the bottom, it can continue fighting. If the opposing robots leave the arena at the same time and it is not possible to clearly determine which one landed first, the fight will be suspended. The participating robots will be immediately returned to their starting positions without repairs, and the fight will restart. If one robot is unable to continue, it loses immediately. If both robots are unable to continue, the winner will be determined by the referee.
6.4.       If one of the robots shows no signs of movement (is unable to move from its place), the referee will start a 10-second countdown. If the robot does not resume movement during this time, it loses. Contact between the immobile robot and its opponent resets the countdown.
6.5.       At any time during the fight, a robot may surrender, which will result in its defeat. The robot driver must make this clear and loud, e.g., by shouting “stop” or banging on the ceiling or structure of the arena.
6.6.       If at any time during the match a LiPo battery is exposed, creating a risk of damage, the match will be terminated immediately and the owner of the exposed battery will lose.
6.7.       In the event of a false start, both robots must return to their starting positions. If the premature start causes damage to the opponent, the robot that caused the error may be declared the loser.
6.8.       A team with multiple robots (clusterbot) is eliminated when 67% of its total weight is eliminated, either by falling out of the arena or by not moving for 10 seconds.
6.9.       Pushing an opponent against the arena wall (without using an active weapon) is only possible for 10 seconds, after which the robot must be completely released.
6.10.   The use of mechanical movement by which a robot restricts the movement of an opponent using an active weapon is possible for 20 seconds, after which the opponent must be completely released.
6.11.    If a robot gets stuck in the arena, it will not be freed.
6.12.   If two robots become stuck together and cannot free themselves, the match will be suspended and the robots will be separated.

Competitors must obey the organizer’s instructions at all times, otherwise they may be disqualified. The organizer has full decision-making authority on all issues raised during the event and situations not specified in the rules..
