1.1.1 Interchangeable body panels or weaponry is allowed between bouts providing changes can be done within a 20-minute time-frame. Interchanging of such panels or weapons cannot be done during bouts.

1.1.2 Limited time will be allowed between bouts for repairs, adjustments, changing of batteries, etc.

1.1.3 Any on-board equipment that could require attention during the program recording - e.g. recharging of pressure reservoirs; charging batteries; changing receiver (RX) crystals - should be easily and quickly accessible.

1.1.4 All Robots must have a cradle in which it can sit with the drive wheels or tracks supported off of the ground. The cradle must allow the Robot's drive to be demonstrated on the workbench without the Robot moving. (Wheels should not be fitted to the cradle).

1.2.1 Robots will be inspected for safety and reliability before being allowed to compete.

1.2.2 The Organizers reserve the right to ban or disqualify any Robot that, in their opinion, is/could be unsafe and cause injury to personnel or damage to the television studio set or equipment.

1.3.1 Robots can be built using wheels; tracks; legs ("Walkers").

1.3.2 Other styles or methods may be considered, but contact the Organizers before starting work.

1.3.3 Flying Robots that use exposed rotating aerofoils are banned.

1.3.4 "Cluster Bots" - Robots consisting of two or more components - are allowed. They must enter the arena as a single object, and if 50% of the robots are immobilized then the team would be deemed to have lost that bout.

2.1.1 Weight Classification

2.1.2 i) Legged Robots ("Walkers") are permitted to enter the weight classification one below their actual weight.

2.1.3 Total weight is measured without consumables - e.g. gases, fuel - and does not include safety bars, straps, guards or similar equipment used to immobilize moving arms/weapons, or for protection, and which are removed before battle. (Please note that batteries will not be considered as consumables.)

2.1.4 If interchangeable panels and/or weapons are used, the weight is measured with the heaviest set-up in place.

2.2.1 Overall length must not exceed 6.6ft (2 meters). Overall width must not exceed 4.6ft (1.4 meters).

2.2.2 Legged Robots ("Walkers") may exceed these dimensions, but check with the Organizers before starting work.

2.2.3 There is no maximum height for a Robot. (This will be dictated by design and weight constraints.)

2.2.4 Length and width is measured to the extremities of the Robot, i.e. includes any overhanging bodywork, weaponry or protrusions.

2.2.5 Providing the Robot starts a bout with weaponry or other devices in a retracted position, the length and width is measured with these in this retracted position.

3.1.1 i) Motive power for the drive and/or weapons may be electric, internal combustion (IC), hydraulic, or pneumatic.

3.1.2 i) All Robots must be fitted with on-off switches that operate both radio receiver and drive/weapon circuits - in practice totally removing all power from the Robot.

3.1.3 If the proposed Robot design (e.g. a completely revolving body) could make conforming to some or all of Regulations 3.1.2 impractical, contact the Organizers before starting work.

3.2.1. Working voltages must not exceed 36V DC (mean voltage) or 36V RMS AC.

3.2.2. All power connections (connections carrying a heavy current) must be of an adequate grade and adequately insulated. Cables must be routed to minimize the chances of being cut.

3.2.3. Batteries must be totally sealed and not contain free-flowing liquid. (Whether electrolyte or otherwise.)

3.2.4. Battery connections must be adequately insulated.

3.3.1 Fuel capacity is limited to 17floz (500ml).

3.3.2 i) Separate fuel tanks must be made of an acceptable type of plastic (e.g. nylon).

3.3.3 All fuel lines must be of the correct type and held with the correct type of fittings. They must be routed to minimize the chances of being cut.

3.3.4 A return spring must be fitted to the throttle of all IC engines to return the throttle to "idle" or "off" in the case of servo breakage or failure. (This is in conjunction with any failsafes.)

3.4.1 Hydraulic pressure is limited to 3000psi.

3.4.2 Hydraulic fluid storage tanks must be of a suitable material.

3.4.3 Hydraulic fluid lines and fittings must be U.L. Approved (or similar) specification. The lines must be routed to minimize the chances of being cut.

3.5.1 Pneumatic pressure is limited to 1000psi.

3.5.2 i) Pressure bottles/vessels/reservoirs must be of an acceptable type - i.e. commercially manufactured to contain gas at pressure and have a current valid test certificate. The pressure used must not exceed the manufacturer's specifications.

3.5.3 Pneumatic lines and fittings must be U.L. Approved or similar specification. The lines must be routed to minimize the chances of being cut.

3.5.4 All gases in pneumatic systems must be inert or non-inflammable - e.g. air, carbon dioxide (CO2), argon (Ar), or nitrogen (N2).

3.5.5 i) All gas bottles/reservoirs and the values/regulators must be contained within the body of the Robot to protect them from puncture.

3.5.6 A pressure relief/safety value must be fitted on the high-pressure side of the circuit set at 1000psi. (A diaphragm valve may also be used.)

3.5.7 The pneumatic system must be capable of being vented without removal of fittings.

ii) Tethered projectiles are allowed, but the tether may not exceed 8ft (2.44 meters) in length, (measured from the center of the Robot to the tip of the projectile).

ii) Locking pins must be painted red or have a red tag attached and MUST be in place at all times - except in the arena. (These locking pins are not included with the overall weight.)

ii) This MUST bring that circuit to a pre-set "off" or "zero" position if the transmitter (TX) signal is lost, to prevent further operation.

iii) The fail-safes may take the form of plug-in commercial devices; electronic circuitry incorporated into some receivers - e.g. PCM-type - or other devices - e.g. Vantec speed controllers.

iv) Whichever device(s) is selected, it MUST operate to the Organizer's satisfaction before the Robot will be allowed to compete. (See Technical Sheet No. 1.)
