Robot combat is a hobby in which two or more custom-built machines use varied methods of destroying or disabling the other. As of today, in most cases these machines are remote-controlled vehicles rather than autonomous robots, although there are exceptions, particularly in the field of robot-sumo.
Robot combat enjoyed a period of mainstream exposure in the late 1990s and early 2000s when several television shows broadcast the robot fights. Either the public or the TV network administrators lost interest, and the shows dropped from the airwaves. The most well-known of these shows were Battlebots, Robot Wars, and Robotica. Although the mainstream was lost after the cancellation of those shows, robot combat has a large dedicated cult following and there are still dozens of smaller competitions around the UK, USA and in other countries every year. Combat robots have received mention in the press and entertainment shows from time to time as well. Battlebots itself would return to ABC in the United States in 2015 as a summer series, with Robot Wars returning alongside a second series of Battlebots in 2016.
Robot builders may be of any age and come from any walk of life. The robots themselves can range from modified remote controlled toys weighing less than a pound to three-hundred plus pounds of exotic metallurgy and sophisticated electronics. Although building a combat robot can cost thousands of dollars and hundreds of hours, some schools use the construction of combat robots in their courses to teach mechanical design and technology. For schools that shy away from the violence of combat robots, there are robotic competition alternatives such as the cooperative competitions FIRST and BEST Robotics. Robot competitions such as RoboGames, offer a mix of combat and non-combat events.
In 2015, the United States-based robotics company MegaBots with their giant robot Mark II challenged a Japanese-based robotics company Suidobashi Heavy Industry with their giant robot Kuratas to a one-to-one combat, a challenge that Suidobashi accepted. The duel was expected to take place in June 2016.
Among the oldest robotic combat competitions extant in the United States are the "Critter Crunch" (founded about 1987) in Denver and "Robot Battles" (founded in 1991) based in the southeastern U.S. Both events are run by members of the "Denver Mad Scientists Society".
1987 - The "Denver Mad Scientists Society" organized the first Critter Crunch competition  at Denver's MileHiCon science-fiction convention.
1994 - Marc Thorpe organized the first Robot Wars competition in San Francisco. Four annual competitions were held.
1997 - Rights to the Robot Wars name is transferred to British TV production company who produce the Robot Wars television series. Early seasons feature competitive games and obstacle courses as well as simple combat. The series aired 151 episodes across 12 series from 1997 to 2003. Special series were produced for the United States and the Netherlands.
1999 - Former Robot Wars competitors in the U.S. organize a new competition named BattleBots. The first tournament was shown as a webcast, with the second tournament shown as a cable 'Pay-per-view' event.
2000 - BattleBots is picked up as a weekly television program on Comedy Central. It would span five seasons ending in 2002.
2001 - Robotica appears on The Learning Channel as a weekly series. The format features tests of power, speed and maneuverability as well as combat. The show ran in three series, ending in 2002.
2002 - Foundation of the Robot Fighting League, a regulatory body composed of the organizers of robot combat events in the United States, Canada, and Brazil. The body produces a unified set of regulations and promotes the sport.
2008 - ROBOlympics changes its name to RoboGames and, while most events are not combat related, Robot Combat is significantly featured.
2016- Robot Wars returns to British television on BBC2.
Robots come in all shapes and sizes, but there are certain defining lines that robots rarely stray across, thanks to official rules and practicality. The standard by which all combat robots are measured is weight; the everyday dilemma of the robot builder is to cram as much power into as little weight as possible. Robots can be as small as the 25 gram 'Nanoweight' class, and as large as the 340-pound 'Super Heavyweight' class. The common weightclasses are as follows:
- 25g- Nanoweight
- 75g- Fleaweight
- 150g- Antweight (US - Fairyweight)
- 1 pound (454 g) - Poundweight (US - Antweight)
- 1 kilogram (2.2 lbs) Kilobot (Canada)
- 3 pound (1.36 kg) - Beetleweight
- 6 pound (2.72 kg) - Mantisweight
- 12 pound (5.44 kg) - Hobbyweight
- 15 pound (6.80 kg) - BotsIQ Mini class
- 30 pound (13.6 kg) - Featherweight/Sportsman class
- 60 pound (27 kg) - Lightweight
- 120 pound (54 kg) - Middleweight / BotsIQ Large class
- 220 pound (100 kg) - Heavyweight
- 340 pound (154 kg) Super Heavyweight
There are some international variations in weight class - for example, UK robot builders define the UK Antweight class limit as 150g. Whereas in the US an Antweight class was later defined to be 1 pound. The 2016 reboot of Robot Wars has a heavyweight limit of 110kg (242lbs), while the 2015 Battlebots reboot has a heavyweight limit of 250lbs (113.2kg).
Weight is a precious asset for robot builders. For the sake of diversity of design, the rules often give an extra weight allotment for robots that can walk rather than roll on wheels. Such robots are more difficult to construct and their drive mechanisms are heavier. Some builders opt to build walking robots, taking advantage of the extra weight to add more powerful weaponry at the expense of greater complexity and fragility.
Given the violent nature of robot fighting, safety is always the most important issue at robot events. Robot fights take place in a sturdy arena, usually constructed of steel, wood, and bulletproof clear Lexan plastic. The size of the arena varies according to the weight class of the robots that are fighting in it. Some large competitions that entertain many different weight classes have more than one arena, because 1lb antweights do not need 50 foot (15 m) wide arenas in which to fight, but 220lb heavyweights do. Having multiple arenas allows the event to progress more quickly.
Competition rules set limits on construction features that are too dangerous or which could lead to uninteresting contests. Strict limits are placed on materials and pressures used in pneumatic or hydraulic actuators, and fail-safe systems are required for electronic control circuits. Generally off-limits for use as weapons are nets, liquids, radio jamming, high-voltage electric discharge, untethered projectiles, and usually fire.
The Robot Fighting League (RFL) was created in 2002 when several builders decided that robot combat needed standardization of rules and judging criteria. The majority of robot combat events in the U.S. as well as events in Brazil, Australia, and Canada have become RFL members and have adopted their ruleset, but some event organizers oppose the direction in which the RFL is taking the sport and remain independent. The topic of event standardization has lent itself to a healthy amount of controversy since the RFL's inception. The UK-based Fighting Robot Association (FRA) performs a similar standardization function for European robot combat.
Combat robot weaponry and design
An effective combat robot must have some method of damaging or controlling the actions of its opponent while at the same time protecting itself from aggression. The tactics employed by combat robot operators and the robot designs which support those tactics are numerous. Although some robots have multiple weapons, the more successful competitors concentrate on a single form of attack. This is a list of most of the basic types of weapons. Most robot weaponry falls into one of the following categories:
- Rammer - Robots employing high-power drive trains and heavy armor are able to use their speed and maneuverability to crash into their opponent repeatedly with hope of damaging weapons and vital components. Their pushing power may also be used to shove their opponent into arena hazards. Rammers (AKA ‘Bricks’) typically have four or six wheels for traction and stability and are often designed to be fully operational when inverted. Robot Wars Series 6 champion Tornado and Series 7 Runner-up Storm II were effective rammers.
- Wedge - Similar in concept to a rammer, the wedge uses a low-clearance inclined wedge or scoop to move in under an opponent and break its contact with the arena floor – decreasing its mobility and rendering it easy to push off into a wall or hazard. The wedge is also useful in deflecting attacks by other robots. Wedges are also used to lift an opponent up to make the attack of another weapon more effective. A small wedge may be attached to the rear of a robot with other weaponry for use as a ‘backup’ in case the main weapon fails. The 1995 US Robot Wars middleweight champion La Machine was an early and effective wedge design as was Robot Wars Series 1 champion, Roadblock (1997).
- Saw Blades - A popular weapon in the early years of robotic combat, these robots use a dedicated motor to power either a modified chainsaw or circular saw, or a custom-built cutting disc, usually at high speeds (up to 10,000 RPM). The serrated blade is used to slice through an opponent's armour to try and reach its internal components. These weapons can create spectacular showers of sparks, and are easy to combine with other designs, but can be ineffective against robots with tougher armour. The aforementioned Robot Wars champion Roadblock had a rear-mounted circular saw in addition to its wedge, while Series 4 runner-up Pussycat had a custom cutting disc with four serrated blades.
- Spinner - Spinners are generally larger and heavier than saw blades, and spin at a lower RPM. Rather than cutting through the opponent, spinners use a heavy bar, studded disc, or toothed cylinder (drum/eggbeater) to strike the opponent with the kinetic energy stored in the rotating mass. The mass may spin on either a horizontal or vertical axis, although vertical spinners may have maneuverability problems due to the gyroscopic action of the weapon. The destructive potential of a well-designed spinning weapon requires robust arena containment to prevent shrapnel being thrown into the audience. Three-time BattleBots middleweight champion Hazard was a horizontal bar spinner, while Robot Wars Series 3 runner-up Hypno-Disc was a flywheel spinner.
- Full Body Spinner - Taking the concept of the spinner to the extreme, a full body spinner (AKA shell spinner or tuna can spinner) rotates the entire outer shell of the robot as a stored energy weapon. Other robot components (batteries, weapon motor casing) may be attached to the shell to increase the spinning mass while keeping the mass of the drive train to a minimum. Full body spinners require time to spin the weapon up to speed, typically cannot self-right, and can be unstable (BattleBots competitor Mauler being an infamous example). The 1995 US Robot Wars heavyweight co-champion Blendo was the first effective full body spinner. A variant, the ring spinner, features a spinning ring surrounding the robot; these designs have the advantage of being invertible. BattleBots 2015 competitor The Ringmaster is an example of a ring spinner.
- Thwackbot - A narrow, high-speed, two-wheel drive train attached to a long boom with an impact weapon on the end creates a robot that can spin in place at a high speed, swinging the weapon in a horizontal circle. The simplicity and durability of the design is appealing, but the robot cannot be made to move in a controlled manner while spinning without employing sophisticated electronics. The 1995 US Robot Wars lightweight champion Test Toaster 1 was a thwackbot, as were T-Wrex and Golddigger from the BattleBots series.
- Torque Reaction - A variant on the thwackbot is the torque reaction hammer, also known as axlebots. These robots have two very large wheels with the small body of the robot hanging in between them. A long weapon boom has a vertically oriented hammer, pick, or axe on the end. On acceleration, the weapon boom swings upward and over to the rear of the robot to offset the motor torque. When the robot reverses direction, the weapon will swing forcibly back over the top and hopefully impact the opponent. These robots are simple and can put on a flashy, aggressive show, but their attack power is relatively small and, like thwackbots, they can be hard to control. BattleBots 2.0 middleweight champion Spaz was a torque reaction pickaxe robot, whilst Robot Wars Grand Finalist Stinger opted for a disc, later replaced with a bludgeoning mace.
- Lifter - Using tactics similar to a wedge, the lifter uses a powered arm, prow, or platform to get underneath the opponent and lift it away from the arena surface to remove its maneuverability. The lifter may then push the other robot toward arena hazards or attempt to toss the opponent onto its back. The lifter is typically powered by either an electric or pneumatic actuator. Two-time US Robot Wars and four-time BattleBots heavyweight champion Biohazard was an electric lifter.
- Flipper - Although mechanically resembling a lifter, the flipper uses much higher levels of pneumatic power to fire the lifting arm or panel explosively upward. An effective flipper can throw opponents end-over-end through the air causing damage from the landing impact or, in Robot Wars, toss it completely out of the arena. Flippers use a large volume of compressed gas and often have a limited number of effective attacks before their supply runs low. The two-time Robot Wars champion Chaos 2 and BattleBots superheavyweight champion Toro were flippers. While most flippers operate with the pneumatic arm hinged at the machine's rear, Robot Wars' Firestorm achieved remarkable success with a front-hinged flipper, placing third in Robot Wars on three separate occasions (Series 3, 5, and 6) and never failing to advance to the series' semifinal rounds.
- Stabber - Mechanically similar to the flipper is the stabber, which throws or stabs opponents forward instead of upward. An effective stabber can penetrate into the opponent, damage vital inner parts. When they fail to penetrate, they throw their opponent back across the arena into walls or hazards. Stabbers typically use a large volume of compressed gas, which limits the number of times they can fire their weapon in a fight. BattleBots super heavyweight Rammstein was a stabber.
- Clamper - Another lifter variant, the clamper adds an arm or claw that descends from above to secure the opposing robot in place on a lifting platform. The entire assembly then lifts and carries the opponent wherever the operator pleases. Two-time BattleBots super heavyweight champion Diesector was an electric clamper.
- Dustpan - An uncommon variant on the clamper, the dustpan simplifies the design by replacing the lifting platform with a wide box open at the front and top. An opponent maneuvered into the box may then be restrained with an arm or claw from above. Some designs use only the box with no restraining claw. BattleBots middleweight runner-up S.O.B. used a dustpan in conjunction with a sawblade mounted on an arm.
- Crusher - Like flywheels, crushers can be separated into horizontal and vertical variants. Vertical crushers use a hydraulic cylinder attached to a sharp piercing arm to pin and slowly penetrate the top armor of the opponent. Robot Wars Series 5 Champion and two-time world champion Razer was the first vertical crusher, and by far the most successful. Horizontal crushers feature two of these arms, which act like pincers to crush robots between them. Two-time Robot Wars Annihilator champion Kan-Opener is a notably successful horizontal crusher. Enormous strength and careful engineering are required to build an effective crusher; examples are rare, and successful examples are rarer still.
- Overhead Axe - Swinging a high-speed axe, spike, or hammer forcefully down onto your opponent offers another method of attacking the vulnerable top surface. The weapon is typically driven by a pneumatic actuator via a rack and pinion or direct mechanical linkage. The attack may damage the opposing robot directly, or may lodge in their robot and provide a handle for dragging them toward a hazard. BattleBots heavyweight runner-up and Robot Wars competitor Killerhurtz was armed with an overhead axe. Some axes are double-sided, and can strike opponents both in front of and behind the robot; Killerhurtz' successor Terrorhurtz, and Robot Wars Series 2 Grand Finalist Killertron, were examples of this.
- SRiMech - Many robots are incapable of running inverted, due to their shape, weaponry, or both. A SRiMech (self-righting mechanism) is an active design element that returns an inverted robot to mobility in the upright state. The SRiMech is typically an electric or pneumatic arm or extension on the upper surface of the robot which pushes against the arena floor to roll or flip the robot upright. Most flippers, some lifters, and even some carefully-designed axes can double as SRiMechs. Even a vertical spinning weapon may be used as a crude self-righting device. Team Nightmare's lightweight vertical spinner Backlash was designed such that when flipped it would hit the ground with the spinning disc and kick back upright. The first successful unaided use of a SRiMech in competition was at the 1997 U.S. Robot Wars when the immobilized Vlad the Impaler used a dedicated pneumatic device to pop back upright in a match against Biohazard.
Many modern rulesets, such as the rebooted versions of BattleBots and Robot Wars, require robots to have a moving weapon in order to improve the visual spectacle, thus eliminating certain designs such as wedges and thwackbots. It is increasingly common for robots to have interchangeable weaponry or other modular components, allowing them to adapt to a wider range of opponents and increasing their versatility: successful examples include Robot Wars Series 6 champion Tornado and BattleBots 2016 runner-up Bombshell.
Since the first robot combat competitions, some types of weapons have been prohibited either because they violated the spirit of the competition or they could not be safely used. Prohibited weapons have generally included:
- Radio jamming
- High voltage electric discharge
- Liquids (glue, oil, water, corrosives…)
- Open combustion (fire, explosives…)
- Un-tethered projectiles
- Entanglement devices
- Lasers above 1 milliwatt
- Visual obstruction
- Halon - a specific fire extinguishing gas effective as a weapon in stopping internal combustion engines. Note that current rules do not specifically ban Halon as it is no longer commercially available.
Individual competitions have made exceptions to the above list. Notably, the Robotica competitions allowed flame weapons and the release of limited quantities of liquids on a case-by-case basis. The modern series of BattleBots also permits the use of flamethrowers and, as of 2016, untethered projectiles, provided that the latter are merely for show.
Arena hazards have also been granted exceptions to the list of prohibited weapons. Robot Wars in particular used flame devices both in the stationary hazards and on some of the roaming "House Robots", for example Sgt Bash has a flame thrower.
A very wide variety of unusual weapons and special design approaches have been tried with varying success and several types of weapons would have been tried had they not been prohibited.
- Entanglement weapons - Several early US Robot Wars competitors sought to immobilize their opponents with entangling weapons. Nets and streamers of adhesive tape were both tried with mixed success. Entangling weapons were prohibited in Robot Wars and BattleBots from 1997 onward, but the Robotica competitions allowed nets, magnets, and other entangling devices on a case-by-case basis. In the sixth season of BattleBots in 2015, the American broadcast network ABC failed to explicitly exclude entanglement devices, which resulted in a series of controversial decisions.
- Flame weapons - Although prohibited for use by competitors in Robot Wars and the first edition of BattleBots, the rules for Robotica, the Robot Fighting League and the post-2015 version of BattleBots do allow flame weapons under some circumstances. RFL super heavyweight competitor Alcoholic Stepfather and Robotica competitor Solar Flare employed gaseous flamethrower weapons. Flamethrowers are not effective weapons, but are audience favorites.
- Smothering weapons – The BattleBots and Robot Wars lightweight competitor Tentoumushi used a large plastic sandbox cover shaped like a ladybug ("tentoumushi" being Japanese for ladybug) on a powered arm to drop down over opposing robots, covering and encircling them. Once covered, it was difficult to tell what the opponent was doing and who was dragging whom around the arena. One version of the robot had a circular saw concealed under the cover to inflict physical damage, another had a small grappling hook.
- Tethered projectiles – Although tethered projectiles are specifically allowed and discussed in major rules sets, their use is quite rare. Neptune fought at BattleBots 3.0 with pneumatic spears on tethers, but was unable to damage its opponent. During a friendly weapons test, Team Juggerbot allowed the builders of Neptune to take a couple shots against their bot. One of two shots penetrated an aluminum panel below the main armor, while the other bounced off the top armor.
- Multibots (clusterbots) – A single robot that breaks apart into multiple, independently controlled robots has appealed to a few competitors. The Robot Wars heavyweight Gemini and the BattleBots middleweight Pack Raptors were two-part multibots that had some success. The rules concerning clusterbots have varied over the years, either stating that 50% of the clusterbot has to be immobilised to eliminate the robot from the tournament (in the Dutch version of Robot Wars, there was a 3-part multibot named √3, and although one of its parts was tossed out of the arena by Matilda, the robot as a whole was still deemed mobile, and the other 2 parts of √3 did enough to win the match), or that all of a multibot's segments have to be incapacitated before a knock-out victory can be declared. Current Robot Fighting League match rules require the latter to be achieved.
- Halon gas – Rhino Halon fought at the 1997 U.S. Robot Wars event with a halon gas fire extinguisher, which was very effective at stopping internal combustion engines. Gas weapons of this nature were promptly prohibited from future competitions.
The great majority of combat robots roll on wheels, which are very effective on the smooth surfaces used for typical robot combat competition. Other propulsion strategies do pop-up with some frequency.
- Tank treads – Numerous combat robots have used treads or belts in place of wheels in an attempt to gain additional traction. Treads are generally heavier and more vulnerable to damage than a wheeled system and offer no particular traction advantage on the types of surfaces common in robot combat. Most uses of treads are for their striking appearance. The Robot Wars competitors 101 and Mortis along with the BattleBots super heavyweight Ronin used treads. Biteforce, the winner of the 2015 Battlebots Competitions, used magnets embedded in its treads in an attempt to gain extra downforce without extra weight.
- Walking – The spectacle of a multi-legged robot walking across the arena into combat is a big audience favorite. Robot combat rules typically have given walking robots an additional weight allowance to offset their slower speed, the complexity of the mechanism, and to encourage their construction. What the event organizers had in mind was something like the spider-legged robot Mechadon, but what most often was produced were simple rule-shaving propulsion systems that attempted to save as much of the extra weight allowance as possible for additional weaponry. Attempts at more restrictive definitions of “Walking” have effectively eliminated walking robots from competition. BattleBots heavyweight champion Son of Whyachi used a controversial cam-driven “Shufflebot” propulsion system, which was promptly declared ineligible for additional weight allowance at subsequent competitions.
- Gyroscopic precession – Used in the Antweight robot Gyrobot, as well as the Battlebots competitor Wrecks, this system uses a gyroscope and stationary feet that lift as the entire robot rotates due to gyroscopic precession when the gyroscope is tilted by a servo motor. This design can use the gyroscope as a spinning weapon (horizontal or vertical) which allows for efficient double-usage of the gyroscope mass. Although Gyrobot and Wrecks appear to be walking as it translates across the arena, they're not classified as walking robots under current rules. This unusual drive train produces strange and often unpredictable movements, though has shown to be successful in combat.
- Suction fan – Several competitors experimented with the use of fans to evacuate air from a low-clearance shell to suck the robot down onto the arena surface and add traction. Robotica competitor Armorgeddon used a suction fan to increase traction and pushing power, and Robot Wars UK robot TerrorHurtz used a suction fan to counter the forces from its hammer/axe weapon. Similar designs have appeared in robot-sumo competitions where traction is a key factor.
- Magnet wheels – Another approach to gaining traction and stability involves the use of ring-shaped rare-earth magnets as wheels. This is, naturally, only effective in arenas which have magnetic metal surfaces. Due to the expense of large ring magnets, this trick has been used almost exclusively in three-pound and under “insect class” robots, although a lightweight battlebot General Gau tried implementing them. Heavyweight Robotica competitor Hot Wheels attempted to use a large chassis-mounted magnet to gain traction and apparent weight, and Beta Hurtz unsuccessfully attempted to use an electromagnet to counter the reaction forces of its massive hammer weapon at the BattleBots competition. The result ended in the robot being completely stuck to the floor.
- Mecanum wheels – The previously mentioned RFL super-heavyweight competitor Alcoholic Stepfather uses Mecanum wheels and specialized motor control systems that allow it controlled motion in any direction without turning. This is eerie to watch, and disruptive of attack and defense maneuvers by opponents. Root Canal implemented a similar design at BattleBots using Omni wheels angled at 45 degrees.
- Translational drift - Also known as Melty Brain or Tornado Drive, this sophisticated system supplements the thwackbot drivetrain with electronic rotation sensors and rapid speed controller switching that allows a rotating thwackbot to move in a controlled manner while spinning. Several robots have implemented this complex design, but none with particular success. Herr Gepoünden, a lightweight robot, has shown successful use of the Tornado Drive and has used it successfully in smaller competitions. The drive is implemented with an LED light system that tells the driver its current position, indicating where the robot should be driven to.
- Flying – The 1995 US Robot Wars event had a flying competitor: S.P.S. #2 was a lighter-than-air craft buoyed by three weather balloons and propelled by small electric fans. It attempted to drop a net on the opponent. Nearly invulnerable to attack, it won the first match against Orb of Doom (see reference below), but ventured too close to the arena floor in the second match and was dragged down and "popped".
- Rolling sphere – The afore-mentioned Orb of Doom was a featherweight competitor at the 1995 US Robot Wars. It consisted of a lightweight, rigid shell made of carbon fiber-kevlar cloth and polyester resin, applied over a foam core pattern. Inside was an offset-weight mechanism made from a battery-powered electric drill. A similar looking robot named Psychosprout appeared in the UK Robot Wars.
- Rolling tube -Snake competed at Battlebots and the US Robot Wars using a series of actuators to bend its triangular cross-section tubular body to roll, writhe, and slither across the arena.
- Shuffling - refers to the movement of robots that are propelled by a cam-driven system. See Walking
The Combat Robot Hall Of Fame
Robot builders voted in 2003 to name the top combat robots of all time. Twenty-five combat robots from both sides of the Atlantic were elected by their peers to membership in the Combat Robot Hall of Fame, with thirteen robots gaining honorable mention. They achieved their status based on:
- Dominating success in combat
- Pioneering or perfecting influential designs
- Having great fan or entertainment appeal
- Making a lasting impact on the sport.
The hall re-opened for membership in 2005, 2007, 2009, 2011, 2013 and 2015. Over these years an additional fourteen robots were elected to full membership and twenty-one robots were named in the honorable mention roll.
Membership in the Hall is by ballot of the global combat robot community. Notification and balloting instructions appear in combat robot forums in the US, UK, Australia, and India in August of odd-numbered years. A robot appearing on at least 50% of authenticated ballots gains full membership in the Hall, and a robot appearing on fewer than 50% but at least 25% of the ballots appears on the Honorable Mention roll and remain eligible for promotion to full membership in future balloting.
The robots in the Hall were named on at least 50% of the ballots in the year of their induction. They are listed in alphabetical order:
