1e. At any time in a fight a robot may surrender, if so they will be deemed
to have lost.
2. Weight Limit
2a. Robots motivated by rotary motion are limited to 0.15kg (150g)

2c. Robots will be weighed by scales accurate to +/- 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.
3. Physical Size

3b. Robots may expand under remote control.
3c. 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

6a. Composite armour is allowed.
Metal armour is now allowed from 2.2a of the rules
Armour is defined as "a protective layer or skin".
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. 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.

capable of containing any possible shrapnel that particular weapon can
10f. Pneumatics based weaponry can only be used in an enclosed arena and
