"The fitting of interchangeable body panels or alternative 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. Body panels must be the same as the ones removed. Adding extra defensive equipment is forbidden. All interchangeable weapons must not incorporate additional defensive items. All weapons must be declared and logged on the technical check sheet. Failure to do this will result in extra weapons being excluded."

— Section 1.1.1 of the Series 7 Rules & Regulations (2003), concerning requirements for interchangeable weapons

Interchangeable Weaponry is a system where a robot can be modified between battles, allowing the team to change its weaponry. The Robot Wars technical rules allowed for this, as long as:

• The weapons did not push the robot over the weight, height and width restrictions.
• The weapons were offensive additions rather than defensive additions.
• The team declared all the weapons they could use before the tournament.

The concept of interchangeable weapons was first introduced by TMZ in the original 1994 US competition, which was designed with circular saw and pneumatic spike modules. At the same event, The Master also featured a front wedge assembly serving as a weapon guard, which was removed mid-event to improve its saw's reach. The Master later adapted its design to wield an array of 'modular' weapons, including a saw, electric lifter and variations on thwacking blades or flails, securing the 1995 Heavyweight Face-Off co-championship in this form. Two other heavyweights - Tiny Tim and The Beetle - would utilise extra weapon attachments at later stages of their 1994 appearances, in the form of small thwacking blades and a set of 'antlers' respectively.

The first robots to use interchangeable weaponry in the televised UK show were Roadblock, which had interchangeable blades for its rear saw weapon; Killertron, with its double-headed pickaxe and unused mace weapon; and Shogun, which had side spikes which were interchangeable with spikes of different sizes. All three robots first appeared in the first-ever episode, Heat A of Series 1.

The most successful robot to use interchangeable weaponry is Series 6 champion Tornado, which relied on a variety of different weapons - including a spinning drum, a scoop and an 'anti-crusher weapon' - to succeed in later televised appearances. Other successful competitors to use them in recent series include the robots of Team Shock and the Series 9 incarnation of Eruption, although the latter mainly relied on its rear-hinged flipper to finish runner-up in the latter series.

Advantages and Disadvantages

Advantages

Each of Behemoth's scoops had its own advantages, and allowed different tactics to be used

X-Terminator's flipper proved much more effective than its axe in Series 4

Through only being revealed immediately before its uses against Razer in US Season 2 and Series 6, Tornado's horizontal spinner offered a surprise factor when it debuted in each respective series

• Interchangeable weaponry gives a robot a wider range of attacking options and tactics than what can be offered with a single weapon. For example, in Series 9, Behemoth's interchangeable scoop, angled ploughs and grabbing arms gave the team the choice of flipping their opponents with the original scoop, deflecting blows from spinning weapons with the angled ploughs, or pinning down opponents with the grabbing arms.
• Interchangeable weaponry allows the robot to be modified depending on which opponent(s) it faces. For example, in Series 9, Behemoth used one of its angled ploughs, designed specifically to deflect blows from spinners, which helped it to defeat PP3D.
• If one weapon proves ineffective, it can easily be replaced with another. In Series 4, the X-Terminator team found that the robot's axe weapon was not damaging enough, so they changed it to the scoop flipper, which helped X-Terminator win its Heat Final against Behemoth.
  • Alternatively, interchangeable weapons can easily be swapped round when one breaks. This happened to Big Nipper in Series 8, which resorted to using its crushing claws against TR2 after its spinning disc was badly damaged during its Group Battle.
  • Duplicates of a single weapon can also be classed as interchangeable if they are made, brought and used as spare parts. Eruption featured no fewer than four flipper arms in Series 10, including one heavily-armoured variant offering additional defence against powerful spinners.
• Interchangeable weaponry can bring a 'surprise factor' to a robot, that its opponent(s) may not anticipate. Although declared in advance and approved by the Robot Wars technical crew, Tornado's horizontal spinner weapon was not revealed on the show until its battles with Razer in US Season 2, UK Series 6 and UK Extreme 2 respectively. The weapon's existence and effectiveness thus remained unknown prior to its first uses in combat.

Disadvantages

X-Terminator's spike addition prevented it from self-righting

Killertron's mace weapon, originally intended for Series 1, ultimately went unused after Team Trojan found its axe to be more effective

Gabriel's battle axe ended up getting stuck in the Flame Pit, allowing Sir Killalot to attack it

Behemoth's grabbing arms failed to pin down Cherub when used for the first time, leaving the team to wish they had used the scoop

• Each interchangeable weapon will have its own disadvantages, and not all will necessarily be suited for certain opponents.
• Adding an extra weapon to a robot can adversely change a robot's abilities. For example, the spike used by X-Terminator in Extreme 1 prevented it from self-righting, a problem which could have been avoided if it was not fitted at all.
  • Similarly, Storm 2 would not have been able to run inverted with the flywheel.
• Some custom prepared weapons were not allowed to be used as they violated the rules. In Series 6, Team Tornado were not allowed to use their anti-spinner weapon against Hypno-Disc, and their anti-crusher weapon was banned after Extreme 2, with both interchangeable weapons being deemed to be defensive additions.
• Buying and/or building multiple weapons for a robot is more expensive and time-consuming than developing a single weapon.
• Having interchangeable weapons sometimes proves unnecessary, as one weapon can prove much more effective than the others. For example, in Series 1, Killertron had a mace as well as an axe. However, the axe proved effective, so Team Trojan decided to not use the mace and only brought the axe to subsequent series.
• Mixing weapons up gives roboteers less experience with each weapon and how it will operate against a type of opponent. In Series 8, Gabriel experimented with a battle axe which actually proved less effective in its Head-to-Head against Ironside3 after getting caught in the flame pit. As a result, Team Saint reverted to using Gabriel's tried-and-tested sword for its later battles.
  • Some interchangeable weaponry can prove ineffective when used. For example, in Series 9, Behemoth's grabbing arms failed to pin down their opponent properly when used for the first time against Cherub, leading to it losing the battle and being eliminated from the series.

"Putting a grabber of that type onto the robot for a critical match was a very poor decision ... I was so annoyed with the rest of the team for making that decision not to go with a guaranteed win, with using the scoop. It's proven that, sometimes, innovation doesn't pay out - sometimes, it's best to use what you know works."

— Anthony Pritchard on the failure of the grabbing arms

Speed Squared in their Group Battle, only the hook and the lifter were seen. Relied more on the wedge to win battles.	Heavy Metal with the hooking blades
Hercules	1997 US Championship	Electric lifting arm featured multiple configurable parts; at the front, these included tips with three spikes or a 'spatula-like' lip made to counter Blendo. The back of the weapon could house a secondary arm with small spinning weapons - twin 'synthetic diamond wheels', metal cutters or flails - or a static 'hammer'.	Hercules with its spiked lifter and twin cutting discs Hercules battles Blendo with its alternative lifter lip and 'hammer' Hercules battles Thumper in its lifter/flail configuration
Ironside3	Series 9	Interchangeable bar spinners with different edges, including a 'flat edge' and a 'cutting edge'. Only had one blade in Series 8. Series 9 Grand Finalist, finishing third.	Ironside3 in The Pits with both of the two spinning blades
Kan-Opener	Series 6-7, Extreme 2	Armed with a hydraulic crusher featuring a set of interchangeable claws in different colours. Only the blue and grey ones were used on the show.	Kan-Opener in the pits in Series 7 with the range of interchangeable pincers
Killerhurtz	Series 3-4	Originally only had a bladed axe, but in Series 3 and 4, had interchangeable axe heads; a bladed axe and a custom-made spiked axe shaped like a bird's head. Bladed axe was not used in Robot Wars after Series 2.	Killerhurtz's range of interchangeable axes
Killertron	Series 1	In Series 1, Killertron had a double-headed pickaxe which was interchangeable with a swinging mace. The mace was never used due to the axe being more powerful, although it was later lent to Skarab. The axe head could also be fitted with an 'optional' pair of forward-facing spikes; a configuration which would form part of Killertron's regular appearance in later series.
Loco	Series 2	Armed with a spring-powered ram, which had interchangeable blade and spikes.
Matilda	US Season 1-2, Nickelodeon	House Robot. Two separate models with a rear-mounted 27kg flywheel or chainsaw; the latter being originally fitted in Series 1-4. Only the flywheel was used outside the US versions when Matilda was rebuilt for Extreme Series 1.

Nuts 2	Series 10	Three interchangeable outer rings, including hexagonal and square-shaped rings with flails, and a flailless toothed ring. Only the flailed rings were used in combat. Nuts 2's selection of minibots were also interchangeable, with up to two entering from a selection of four.	Nuts 2 with three of its available minibots in Series 10
Orac's Revenge	Series 3	Interchangeable axe blades, though one of the axe blades was used and the others were not used due to being knocked out in round 1 by Steg-O-Saw-Us.
Panzer	Series 3	Interchangeable disc cutter and spikes, though the disc cutter was not used.	Panzer with the spikes and disc cutter
Plunderbird 1	Series 1	The only version of the Plunderbird series to feature interchangeable weapons, each mounted in two separate weapon pods. The pods contained a retracting spike powered by a laser sight device, much like the weapon later used by 101, and an electric circular saw on a moving arm, which flipped out of the robot when operational. As Plunderbird 1 was eliminated at the Gauntlet stage, neither weapon was seen in combat.	Plunderbird 1 with both weapon pods
Pressure	Extreme 2	Had side panels that flipped out to act as separate srimechs, to which spikes could be added to in order to convert them into axes. The spikes were seen on the official photo, but not used in battle.	Official photo of Pressure, with side-mounted spikes not used in televised battles
Pussycat	Series 3-5, 7, Extreme 1	Various cutting discs, beginning with a diamond-edged saw and a carbide-tipped blade which shattered and resulted in its disqualification from Series 3. From Series 4 to its last appearance in Series 7, custom cutting blades in two, four or eight-tooth variants were used; differently-patterned versions of the four-toothed blade were used to great effect in the former. The early Extreme 1 model, Pussycat 2, was profiled in Ultimate Real Robots magazine as wielding both two and four-toothed versions, but ultimately competed on television with just the two-toothed blade. Pussycat's Series 5 team introduction shows it on its pit bench with two four-pointed blades, with Alan Gribble briefly addressing their interchangeability on screen. In Series 7, both eight-toothed double and four-toothed single blades were used.	Pussycat 2 with David Gribble and a four-toothed blade Pussycat in Series 7 with its double blades
Raizer Blade	Series 3	Featured a chainsaw or a bludgeoning spike (called the 'Crucifix of Doom' by the team) as a rear weapon. Only the Crucifix of Doom was used for Series 4.
Razer	Series 6, Extreme 2	Hydraulic crusher was fitted with an optional lifting claw attachment for the Series 6 Grand Final, used to counter Tornado's 'anti-crusher weapon'. A similar attachment with two upward-facing hooks was implemented against Tornado in the European Championship with a similar purpose.	Razer's twin hook attachment, used exclusively against Tornado
Revolution 3	Series 7	Much like Tornado, had a drum (incorrectly referred to as a flywheel) on the front, which could be removed and replaced with a scoop. Only the drum was seen on the show, presumably due to the series' active weapon rules.
Rhino	Series 7	Featured a pair of interchangeable 2,500rpm bludgeoning discs, painted red or grey and attached to the rear. Used alongside the robot's front flipper.	After being damaged by Supernova, Rhino's original red bludgeoner was replaced with a grey equivalent for its Round 2 battle
Roadblock	Series 1	Featured a rear circular saw with the option of three interchangeable blades: a grinding disc, a multi-pointed cutting blade and a square-shaped blade which went unused. Along with Shogun, the first robot to use interchangeable weaponry in the televised show. Weapon was updated to become a single 12-inch tungsten-tipped saw for Series 2.	Roadblock's team and their multiple blades
Robot Redford Jr	1996 US Championship	Originally equipped with a single drill and spear-like arm, the robot gained extra weapons for the Heavyweight Melee event, including a four-sided cutter, 'chain whip', 'harpoon' and front entanglement devices.

Skarab	Series 1	Original steel hammer head was swapped with a mace for the Heat Final stage, lent to it by the Killertron team.	Skarab fights with Killertron's spare mace
Spikasaurus	Series 4	Two sets of 12 or 18-inch front ramming spears, along with a 'bull bar' and a curved scoop designed for Soccer events. The scoop would ultimately go unused on the show, with Spikasaurus often using one set of spears in tandem with the 'bull bar' throughout its appearances.	Spikasaurus with its shorter set of spears
Spike II	1997 US Championship	Featherweight. Two lifting arm designs with spikes or a 'flat metal scoop', though the scooped variety was never used. Changes would also be made to the spiked arm prior to the competition, with the centre spike being replaced by a piece of chiseled steel bar stock.	Spike II
Stinger	Series 4	Interchangeable spiked mace and 5kg grinding disc (nicknamed the 'pizza cutter'), each mounted on the end of a swinging arm. Only the mace was used in Series 4 and all of Stinger's appearances thereafter; the 'pizza cutter' was Stinger's original weapon, which was only used in Series 3.	Stinger in Series 4 with both the mace and 'pizza cutter' weapons
Storm 2	Series 8	Originally a weaponless "full-body hammer" in Extreme 2, had a lifting arm added for Series 7, and a set of interchangeable weapons in Series 8. These weapons include the four-bar lifting arm, a front-hinged flipping arm that allows the robot to self-right, and a vertical spinning disc which was ultimately not used on the show.	Storm 2 with the vertical spinner attached
Sumpthing	Series 3-6, Extreme 1-2	Interchangeable pickaxe/moveable circular saw and lifting forks. Cutting discs were used in Series 5 and Extreme 1, in both single and twin-disc configurations.	Sumpthing, equipped with a single cutting disc in the Extreme 1 Tag Team Terror
Tetanus 2	Series 6, Extreme 2	Interchangeable crusher and lifter. The crusher was used in Series 6, the lifter seen in Extreme 2.	Tetanus 2 fights with a lifter
The Beetle	1994 US Championship	The inaugural Heavyweight runner-up was fitted with an extra set of 'antlers' on the back for the Face-Off final, alongside the subsequent multi-class Melee bout. Purely decorative in function; extremely fragile and susceptible to getting removed by opponents in battle.
The Bishop	1997 US Championship	Middleweight, originally armed with a two-stroke 'abrasive cutting wheel'. When the abrasive disc proved fragile in combat, it was swapped for a diamond saw, but further damage in the Middleweight Face-Off saw The Bishop competing in Melee events without a functioning weapon.	The Bishop in the arena with one of its cutting discs
The Enforcer	1996 US Championship	Lightweight. Originally armed with a 7-inch steel cutting disc, powered by a weedwhacker motor and mounted horizontally on a front chain-driven arm. Reliability issues with the disc lead to the entire weapon being swapped out for an electric lifting arm; The Enforcer reached the final of the Lightweight Melee tournament with the latter configuration.	The Enforcer with its original cutting disc weapon
The Master	1994-1996 US Championships, 1995 UK Open	Pioneering US axlebot initially had a wedge-shaped guard for the circular saw, which could be removed to increase the weapon's forward reach. The 1995-1996 incarnations had a 'modular' design enabling it to use one or two interchangeable weapons at a time. Weapons seen in Robot Wars events included the 4hp circular saw (in vertical or horizontal orientations), a spiked electric lifting arm, a Lexan 'whip' with chain flails, and a triangular-shaped 'sword' blade made from 1/4-inch plate steel. 1995 US Heavyweight Face-Off Co-Champion.

The Morgue/ Mini Morg	Series 4, Extreme 2	Front lifting fork assembly had a second optional configuration, enabling an additional pair of top-mounted spikes to be attached in between smaller front panels. The Morgue fought its Eliminator and appeared in official images with this configuration. The Extreme 2 incarnation of Mini Morg featured a pair of interchangeable vertical spinning discs at the back; both the large and small discs were used during its Tag Team Terror run.

The Steel Avenger	Series 3	Interchangeable spiked and bladed axe heads. It also had a mace, but this was not brought for filming. From Series 4 onwards, only the bladed axe was used.	The Steel Avenger during construction, with the interchangeable axe heads
The Swarm	Series 10	All segments of the clusterbot were interchangeable with each other, enabling Team Big Brother to select different segments depending on which opponents they faced. A total of five segments attended filming, but only four were allowed to enter the arena at any one time. The Swarm's segments included Rubber Duck (flipper), Blenda (bar spinner), Pinza (horizontal pincers) and two versions of Skye - one invertible, the other with entanglement devices.	The Swarm, with four of five interchangeable robots
Thor	Series 8-10	Armed with a spiked hammer in the original series, but this was replaced with a pneumatic axe in Series 8-10 with interchangeable bladed or spiked heads. The Series 9 version had interchangeable front wedges, as well as the interchangeable axe heads. The Series 10 Thor was stated to have five interchangeable axe heads, some of which were referred to as 'hammers' on the official Robot Wars website. However, only two of the bladed heads - including one modelled on Mjölnir - were used in the latter series.	Thor's main axe head in Series 8
Tiny Tim	1994 US Championship	For the multi-class Melee battle, a pair of small spiked blades was added to the rear corners, enabling sit-and-spin attacks. Easily knocked off by opponents in combat.
TMHWK	Series 9-10	Interchangeable bladed and spiked axe heads. The original version, Tomahawk, only had a bladed axe.
TMZ	1994 US Championship	Pioneer of interchangeable weaponry. Modular design - configurable for lightweight, middleweight or heavyweight class events - included two powered weapon modules which were never used as envisioned. A 7-inch sawblade was originally intended to be powered by a weedwacker motor, but ended up being used as a static horizontal weapon after the mechanism was barred during safety checks. A 1/2 inch pneumatic spike was also completed, with a range of 14 inches, but TMZ was eliminated from each of its Face-Off championships before it could be used in battle.	TMZ fights The Master with its static sawblade TMZ's unused pneumatic spike module as fitted to its rolling chassis
Tornado	Series 6-7, Extreme 1-2, US Season 2	Was initially equipped with a pneumatic spike in Series 4, which was replaced with a range of interchangeable weaponry from Extreme 1 onwards. These weapons included: a spinning drum (commonly referred to as a 'disc'); a spiked 'charity' scoop; a static spear; a scoop lifter; a chain flail conversion of the 'charity' scoop; an 'anti-crusher weapon' incorporating a horizontal flywheel or bar spinner; and a vertical bar spinner which was never used. Interchangeable weapons became a signature feature in later appearances. Series 5/Extreme 1 incarnation included two identical drums shown during team introductions; the second presumably being reserved as a spare.	Tornado with the horizontal bar spinner configuration
Track-tion	Series 10	Was lent a wedge from Vulture to protect the robot against spinning weapons. The wedge was used in two battles in place of the robot's regular crusher. Both weapons used the same actuator, enabling the wedge to function as a lifting scoop.	Track-tion equipped with Vulture's wedge
Vicious-1	1997 US Championship	As part of its extensive arsenal, the 1997 Middleweight Face-Off champion employed two near-horizontal spinning weapons on the back to damage opponents: a double-ended "Spiked Hammer Arm", and a similar weapon comprising of a 'spring-dampened' metal cable with steel blades.	Vicious-1 fights Peaches with its bladed cable weapon

Trivia

• In Series 7, Ripper's flipper was said to be interchangeable with a disc and an axe, but John Findlay later revealed that this was not actually true, and that he had made it up for the benefit of viewers.
• In Series 7, 13 Black used a different front spinning disc in its Round 2 battle against Gravity while Spawn Again and Bulldog Breed used different flipper plates in their losses to Raging Knightmare and X-Terminator respectively.
