ANTWEIGHT RULES 2.3
1a. The arena will be a raised platform 30" (762mm) square.
1b. At least 50% of the arena must have a drop off area.
1c. A robot that falls off the arena will be deemed to have lost.
1d. A robot unable to right itself after 10 seconds will be deemed to have lost.
1e. At any time in a fight a robot may surrender, if so they will be deemed to have lost.
1f. A judge will call cease when it finds a robot to be immobilised. That robot will then have ten seconds to right its self/ regain control. If not then it will be deemed to have lost and the match continue with it still in place but not under control.
2. Weight Limit
2a. Robots motivated by rotary motion are limited to 0.15kg (150g)
2b. Robots motivated by non-rotary motion (i.e. walkers) are limited to 0.225kg (225g)
2c. Robots will be weighed by scales accurate to at least +/- 1g.
2d. The weight limit is judged as the 'fighting weight' entering the arena.
If in doubt check the accuracy of your scales or robot against a POST OFFICE set and build to the limit of your scales. If your scales are 5g accurate you could end up building a 152.5g robot.
“Shuffle Bots” will be classed as walkers and therefore are eligible for the 0.225kg(225g) weight limit.
3. Physical Size
3a. All robots to be contained within a 4” (101.6mm) cube prior to competition.
3b. A robot must be able to be removed from the 4” cube and placed directly into the arena without any modifications being made to it.
3c. Robots may expand under remote control.
3d. Antennas must be contained within this cube.
4. Energy Source
4a. Batteries must not contain acid/liquid electrolyte.
4b. No voltage greater than 24.0V is permitted.
4c. A power switch must be included and easily accessible and provide full shutdown.
5a. Metal weapons are permitted (see rule 6b)
5b. Fluid based weapons (treacle guns, etc..) are NOT permitted.
5c. Glue or sticky pad weapons are NOT permitted.
5d. String or entanglement weapons are NOT permitted.
5e. Flame based weapons are not permitted
5f. The use of electricity as a weapon is NOT permitted.
5g. Explosives based weapons are NOT permitted.
5h. Any system involving the use of pressurised gas shall be limited to 100p.s.i (7 Bar)
5i. For safety purposes all weaponry must be able to be shutdown remotely.
5j. Un-tethered weapons are NOT permitted: should a weapon break off in a competitor it will be considered Un-tethered.
5k. Any tethered weapon must have an adequate connection to prevent the weapon becoming un-tethered.
5l. Tethered weapons range is to be no more than 3’ (914mm)
5m. High-impact (e.g. rotating) weapons can only be used within a battlebox capable of containing any possible shrapnel that particular weapon can create.
5n. Pneumatics based weaponry can only be used in an enclosed arena and must be shown to be safe prior to competition.
5o. Rotating weapons, which may shatter, are NOT permitted
5p. Scalpel blades ARE permitted
6a. Composite armour is allowed.
6b. Maximum Thickness of Metal is 1mm or 0.040" or 18 gauge
(+/- 5% tolerance)
6c. Panels of metal may not be continuous to more than one plane.
Armour is defined as "a protective layer or skin".
Monocoques are defined as armour.
Metal may be bent but the whole robot may not be constructed out of one continuous piece of metal.
7. Remote Control of
7a. The following frequencies are acceptable: 27 MHz, 40 MHz, 418 MHz, 433-434 MHz, 868 MHz and 2.45 GHz
7b. Magnetic/inductive systems are NOT allowed. (Due to possibility of interference with later arena designs).
7c. When the control transmitter is switched OFF or out-of-range or subject to interference the robot must 'FAILSAFE'.
7d. Contestants must register the possible frequencies that their controllers' use (including which crystals they have) with 'FREQUENCY CONTROL' at least 7 days before the CONTEST.
7e. Contestants must obey frequency control at all times. Any contestant not obeying frequency control may be disqualified.
7f. All controls must be CE & MPT compliant.
8. Duration of Activity
8a. The maximum length of any BATTLE will be 180 seconds (3 minutes).
9. During BATTLE
9a. Robots may hold or pin each other for a maximum of 20 seconds.
9b. Robots that don't wish to carry on can "surrender" a robot that does surrender shall be declared as the loser.
9c. The JUDGE will give a verbal warning at 15 seconds into any holding or pinning for the contestants to disengage, should they not do so within 20 seconds the BATTLE will be stopped and the robots returned to their respective corners and the BATTLE recommence immediately.

17b. The total weight of all botlets together in a rolling Cluster bot must not exceed 150g
17c. The total weight of all botlets together in a non-rotary powered Cluster bot must not exceed 225g
