Home Up Contents



1. Arena

1a. The arena will be a raised platform 3’ (914mm) square.

1b. There will be a drop off edge all around the arena.

1c. A robot that falls off the arena will be deemed to have lost.

2. Weight Limit

2a. Robots motivated by rotary motion are limited to 0.15kg

2b. Robots motivated by legs (walkers) are limited to 0.225kg

2c. Robots will be weighed by scales accurate to +/- 1g.


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.

3. Physical Size

3a. All robots to be contained within a 4" (101.6mm) cube prior to competition.

3b. Robots may expand under remote control.

3c. Antennas must be contained within this cube.

4. Energy Source

4a. Batteries must not contain acid.

4b. No voltage greater than 24.0V is permitted.

4c. A power switch must be included and easily accessible and provide full shutdown.

5. Weaponry

5a. Fluid based weapons (treacle guns, etc..) are NOT permitted.

5b. Glue or sticky pad weapons are NOT permitted.

5c. String or entanglement weapons are NOT permitted.

6. Armour

6a. No metal is to be used in armour.


6g. Armour is defined as "a protective layer or skin".

6h. Monocoques are defined as armour.

7. Remote Control of Robot

7a. The following frequencies are acceptable: 27 MHz, 40 MHz, 418 MHz, 433-434 MHz, 868 MHz, 2.45 GHz

7b. Ultrasonic control, infrared control & 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. All controls must be CE & MPT compliant.

8. Duration of Activity

8a. The maximum length of a "one on one" BATTLE will be 120 seconds (2 minutes).

9. Contact during BATTLE

9a. Robots may hold or pin each other for a maximum of 20 seconds.


9b. 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 by 20 seconds the BATTLE will be stopped and the robots returned to their respective corners and the BATTLE recommence immediately.

10. Weapons

10a. Un-tethered weapons are NOT permitted: should a weapon break off in a competitor it will be considered un-tethered.

10b. Tethered weapons range is to be no more than 3’ (914mm)

10c. Any weapon that rotates must not exceed 10 metres per second tip speed. This primarily a safety issue.

11. Thermal Warfare Weaponry

11a. Explosives or pyrotechnic detonators or similar devices are NOT permitted.

11b. Any thermal warfare device must be capable of being switched off by remote control (this maybe incorporated into the fail-safe).

11c. Any contestant using a thermal warfare device is responsible for proving & demonstrating it’s safety to the JUDGE(S).

11d. Any contestant using a thermal warfare device MUST bring a suitable certified fire extinguisher, the use of which must not damage the arena or another contestant (i.e. no water! - CO2 preferred).

11e. Contestants are responsible to clearing the use of any thermal warfare device with the owners of the CONTEST venue.

11f. Candles or wick based devices are NOT permitted.

11g. Napalm or similar compounds are NOT permitted.

12. Outside Assistance

12a. Outside manipulation is NOT permitted during the contest.

13. Safety Equipment

13a. All entrants must provide & wear their own approved safety goggles throughout any BATTLE.

13b. Protective gloves must be worn when handling the robots.

14. Protection from Sharp Edges

14a. All sharp edges must have protective covers outside the arena.

14b. These are to be painted bright yellow.

15. Contestant Interaction

15a. Contests must communicate in a socially acceptable way to each other.
