Robot Wars Series 5 Rules
1. GENERAL, SAFETY and STYLE
1.0 The Organisers, at their sole discretion, reserve the right to alter or change these specifications at any time.
1.1 General Construction
1.1.1 Interchangeable body panels or weaponry is allowed between bouts providing this can be done within a 20-minute time-scale. Interchanging of such panels or weapons cannot be done during bouts.
1.1.2 Limited time will be allowed between bouts to make 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 in Middle and Heavyweight classes 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 Organisers reserve the right to ban or disqualify any robot that in their opinion is/could be unsafe and cause injury to personnel, or unacceptable damage to the television studio, set, equipment or battle arena.
1.3.1 Robots can be built using wheels, tracks and legs ("Walkers").
1.3.2 Other styles or methods may be considered, but contact the Organisers before starting work.
1.3.3 Flying Robots that use exposed rotating airfoils 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% or more of the Cluster Bot is immobilised, the robot will be deemed to have lost that battle.
2 WEIGHTS and DIMENSIONS
2.1.1 Weight Classification
(Please contact the Organisers before building an 'Extreme weight robot)
2.1.2 Legged Robots ('Walkers') can weigh up to 200kgs/4411bs in the Heavyweight class.
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 immobilise 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 2 meters. Overall width must not exceed 1.4 meters.
2.2.2 Legged robots ('Walkers') may exceed these dimensions, but check with the Organisers 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 MOTIVE POWER
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 Organisers 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 minimise 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 IC Engines
3.3.1 Fuel capacity is limited to 500m1 (17 fl.oz).
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 minimise 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. See regulation 5.4.)
3.4.1 Hydraulic pressure is limited to 3000 psi/204 bar/20.4 mps.
3.4.2 Hydraulic fluid storage tanks must be of a suitable material.
3.4.3 Hydraulic fluid lines and fittings must be to BS (British Standard) specification. The lines must be routed to minimise the chances of being cut.
3.5.1 Pneumatic pressure is limited to 1000 psi/68 bar/6.8 mps.
3.5.3 Pneumatic lines and fittings must be to BS (British Standard) specification. The lines must be routed to minimise 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).
3.5.6 A pressure relief/safety value must be fitted on the high-pressure side of the circuit set at 1000 psi. (A diaphragm valve may also be used).
3.5.7 The pneumatic system must be capable of being vented without removal of fittings.
4.1 All pyrotechnics (see 4.2); explosives; flames; firearms; corrosives; liquids; electronic devices - e.g. radio jamming, heat-guns, Tesla coils are banned.
4.2 Small, non-offensive pyrotechnics - e.g. flash puffs - May be allowed at the Organiser's discretion.
4.3 Devices using inflammable or combustion-supporting gases are banned.
4.5 The speed of any rotating weapons - e.g. circular saws, carbon or steel cutting discs - must not exceed the manufacturer's specification. The manufacturer's specification must be available for inspection.
4.6 Rotating hardened steel blades that may shatter are not allowed.
4.7 Commercial blades - e.g. bayonets - must not exceed 2Ocm/8inches in length.
4.8 All sharp edges of weapons, including fixed weapons - e.g. spikes -and robot bodywork in general that is sharp, MUST be fitted with adequate protection that must be in place at all times except in the arena. (These guards are not included with the overall weight of the robot).
4.10 Self-contained weapons - e.g. IC powered cutting discs - must have a secondary restraint fitted in the event of the main fitting breaking way.
4.11 Lasers up to Class 2 (1mw) are allowed.
5 RADIO CONTROL
5.1 All Robots MUST use VHF frequency band 40MHz. (With the exception of 5.2 or 5.3 below.)
5.2 Feather and Lightweight Robots MAY use the VHF Frequency band 27 MHz FM. A quality set (i.e. one that uses interchangeable crystals) must be used.
5.3 The UHF frequency band 459 may be used - but inform the Organisers at the earliest opportunity.
5.5 At least three pairs of transmitter (TX) and receiver (RX) crystals of different frequencies must be available for each RC set up involved in running the Robot e.g. if two separate TX/RX sets are used, there must be six different pairs of crystals available.
