Game No :01 – Robot Combat

Robot combat is a mode of robot competition in which custom-built machines fight using various methods to incapacitate each other. The machines have generally been remote-controlled vehicles rather than autonomous robots. Robot combat competitions have been made into television series, including Robot Wars in the UK and Battle Bots in the US. Robot builders are generally hobbyists and the complexity and cost of their machines can vary substantially. Robot combat uses weight classes, with the heaviest robots able to exert more power and destructive capabilities.

The rules of competitions are designed for the safety of the builders and the organizing team. Robot combat arenas are generally surrounded by a bulletproof screen.Competitor robots come in a variety of designs, with different strategies for winning fights. Robot designs typically incorporate weapons for attacking opponents, such as axes, hammers, flippers, and spinning devices. Rules almost always prohibit gun-like weapons as well as other strategies not conducive to the safety and enjoyment of participants and spectators.

Robot combat involves remotely controlled robots fighting in a purpose-built arena. A robot loses when it is immobilized, which may be due to damage inflicted from the other robot, being pushed into a position where it cannot drive (though indefinite holds or pins are typically not permitted), or being removed from the arena. Fights typically have a time limit, after which, if no robot is victorious, a judge or judges evaluates the performances to decide upon a winner.

Brining the same kind of set up by E Robots Sports to India
Given the violent nature of robot fighting, safety is a central factor in the design of the venue, which is generally a sturdy arena, usually constructed of steel, wood, and bullet resistant clear polycarbonate plastic. The medium, lighter classes compete in smaller arenas than the heavyweights. 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, deliberate radio jamming, high-voltage electric discharge, untethered projectiles, and usually fire.

Robot fighting associations
The sport has no overall governing body, though some regional associations oversee several events in managerial or advisory capacities with published rulesets. These include:
• Robot Fighting League (RFL), primarily U.S., operated 2002—2012
• Fighting Robot Association (FRA), U.K and Europe, 2003–present
• Standardised Procedures for the Advancement of Robot Combat (SPARC), U.S., 2015–present
• E Robot Sports India 2023 – present
The major televised competitions have operated outside of these associations.

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:
Inactive weaponry
Inactive weaponry does not rely on a power source independent from a robot's mobility. Many modern rulesets, such as the rebooted versions of BattleBots and Robot Wars, require robots to have an active weapon in order to improve the visual spectacle, thus eliminating certain designs such as torque-reaction axlebots and thwackbots, and requiring other designs such as wedges and rammers to incorporate some other kind of weapon. • 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 the hope of damaging weapons and vital components. Their pushing power may also be used to shove their opponent into arena traps. Rammers (AKA 'Bricks') typically have four or six wheels for traction and stability and are often designed to be fully operational when inverted. Because many modern rulesets require all robots to have a moving weapon, modern rammers are often equipped with other weapon types. Robot Wars Series 6 champion Tornado and Series 7 runner-up Storm II were effective rammers. The former used interchangeable weaponry (usually a small spinning drum) while the latter opted for a lifting arm to avoid disqualification. Battlebots 3.0 superheavyweight champion Vladiator was a rammer armed with a small lifting spike. The D2 beetleweight kit bot is a popular and effective rammer design for entry-level hobbyists.

• Wedge – Similar in concept to a rammer, the wedge uses a low-clearance inclined ramp 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 trap. The wedge is also useful in deflecting attacks by other robots. Small wedge-lets are used to lift an opposing bot and feed it to a secondary weapon system. 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. Like rammers, modern wedges must be combined with some other weapon in order to be legal in some modern competitions. The lower the degree of inclination of the wedge, the higher the chances of lifting the opponent bot from the ground. The 1995 US Robot Wars middleweight champion La Machine was an early and effective static wedge design, as was Robot Wars Series 1 champion, Roadblock in 1997. Two-time lightweight BattleBots champion Dr. Inferno Jr. was a low rectangular machine surrounded on all sides by hinged wedges. 2018 BattleBots competitor DUCK! utilized a powered lifting wedge. Original Sin is a four-wheeled ramming robot which has won eight heavyweight RoboGames competitions thanks to a combination of durability and hinged wedges. The Panzer series of robots have managed to win several competitions (Robotica season 3 and both seasons of Robot Wars: Extreme Warriors) with six-wheeled drive and a powered or unpowered wedge.

• Thwackbot – A narrow, high-speed, usually two-wheel drive 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 are appealing, but the robot cannot be made to move in a controlled manner while spinning without employing sophisticated electronics (See Melty-Brain Spinner, below). The 1995 US Robot Wars lightweight champion Test Toaster 1 was a thwackbot, as were T-Wrex and Golddigger from the BattleBots series.

o 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 brakes or 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 Series 4 Grand Finalist Stinger primarily relied on a bludgeoning mace. BattleBots 3.0–5.0 semifinalist Overkill combined a wedge with a massive swinging blade.


Spinners are weaponry based around blades, cylinders, discs, or bars rotating at high speed around an axis. This is among the most popular and destructive forms of weaponry, thanks to its potential to quickly deliver a high amount of kinetic energy over a small area.

• 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 armor 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 armor. 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. BattleBots 5.0 middleweight runner-up S.O.B. used a wide metal box (a "dustpan") in conjunction with a saw blade mounted on an arm. While true saws are obsolete in higher weight classes, a vertical spinner mounted on an articulating arm has seen renewed popularity in recent years. BattleBots 2023 champion SawBlaze combines a three-pronged dustpan design with a "hammer saw": a spinning blade mounted on a 180º pivoting arm.

Robot Wars series 9–10 competitor Aftershock used a vertical spinning flywheel to attack opponents.

Vertical Spinner – A vertical disc or bar spinner consists of a thick circular disc or flat bar mounted on a horizontal axis. Rather than many small teeth to cut like a saw, most spinners have few large teeth to catch opponents and either throw them into the air or rip off chunks of armor. Vertical spinners are ubiquitous at all levels of competition, especially in the US. A majority of BattleBots competitors use spinning vertical discs or bars, including 1.0 lightweight champion Backlash, its heavyweight brother Nightmare, 2018–2019 champion Bite Force, and 2021 champion End Game, among many others. 2022 BattleBots champion Tantrum bears a "puncher", with a small vertical spinner mounted on a sliding mechanism. Vertical spinners are less common in Robot Wars, with Series 5–6 competitor S3, Series 7 grand-finalist X-Terminator, and Series 9–10 competitor Aftershock as three notable exceptions. o Drum Spinner – Drum spinners are a variant of vertical spinners, consisting of a thick, short cylinder resembling a steamroller's wheel with teeth spinning on a horizontal axis. Drum spinners can accelerate faster than vertical discs or bars, but have less reach. Good drum spinners can land a solid hit almost every time they contact another robot and send it flying as high as a normal vertical disc or bar. Drums are also much thicker, meaning almost the entire front of the robot is taken up by a weapon. Drum spinners have a tendency to suffer from extreme drive issues due to the large amounts of gyroscopic forces

o Eggbeater – An eggbeater spinner is similar to a drum but uses a broad rectangular frame, rather than a solid cylinder as its choice of weapon shape. Eggbeaters are more lightweight than drums, but due to their less aerodynamic design, they are usually most effective at lower weight classes. The 3 pound (Beetleweight) robot Lynx has dominated its weight class to such an extent that it is being retired to give other teams a chance to win. o Vertical discs, bars, drums, and eggbeaters are continuous with each other to the point where it can be difficult to cleanly define each weapon type. For example, BattleBots 2019 and 2022 runner-up Witch Doctor has used a two-toothed "disc", which is narrower than a drum but broader than a disc. BattleBots competitor Copperhead uses a broad steel drum with notches cut out, giving it similar properties to an eggbeater. Brazilian Team Warrior has fielded successful disc and eggbeater bots at multiple weight classes, including Federal M.T. (four-time RoboGames lightweight champion), General (two-time RoboGames middleweight champion), and Black Dragon (2019-present BattleBots competitor)

• Robot Wars series 9 champion Carbide was a two-wheeled bot with a horizontal spinning bar
Horizontal Spinner – Horizontal spinners rotate around a vertical axis, with the rotating blade or disc typically mounted below, under, or at mid-height on the front of the robot. Under cutters have a spinner low enough almost to scrape the ground. Thanks to their broad reach, horizontal spinners can impart large impacts and may throw other robots across the arena floor. Tombstone, a spinner armed with a horizontal bar, was the champion of BattleBots 2016, and its sister machine Last Rites has been a renowned competitor in RoboGames since 2005.

Full Body Spinner – Taking the concept of the spinner to the extreme, a full-body spinner rotates a massive horizontally spinning mechanism around the entire circumference 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 more time to spin the weapon up to speed, typically cannot self-right without the assistance of stabilizing bars.

Shell spinner – Shell spinners are the most common variety of full body spinner, encasing the robot in a spinning shell powered from below by an electric motor. These shells may be cylindrical, conical, or dome-shaped. The 1995 US Robot Wars heavyweight co-champion Blendo was the first effective shell spinner, with its weapon derived from a metal wok

Ring / Rim spinner – Robots with ring or rim spinners impact opponents with a ring-shaped blade or battering surface spinning around the circumference of the chassis. These designs have the advantage of invertibility, at the cost of complexity, since they rely on a series of gears to translate motor power to the external ring. BattleBots 2016 competitor The Ringmaster is an example of a ring-spinner. o Cage / Overhead spinner – A cage spinner impacts opponents with a spinning open frame resembling a helicopter rotor rather than a solid shell. These spinners are particularly uncommon. The most notable example is BattleBots 3.0 heavyweight champion Son of Whyachi, armed with bludgeoning hammer heads attached to a triangular spinning frame.

o Full-body drum spinner – A full body drum spinner is similar in construction to a thwackbot, with a tubular two-wheeled chassis encased by a vertically spinning cylindrical shell. These designs are rare and notoriously unreliable despite their high damage potential. Examples include Robot Wars competitor Barber-Ous and BattleBots competitor Axe Backwards.

o Melty-Brain Spinner (also known as Tornado Drive or Translational Drift)– A variation of the full-body spinner designed to operate without an independent weapon motor. These robots utilize a complex combination of rotational sensors and fine motor control to drive in such a way that the entire robot can simultaneously rotate on the spot and move across an arena in a controlled manner. The drive is usually implemented with an LED light system that indicates to the driver the direction the robot will move when commanded to move forwards. This kind of design tends to be incorporated into invertible builds and requires a spin-up time like other spinners. One of the earliest known examples of this kind of robot is BattleBots lightweight Herr Gepoünden, a thwackbot which reached the quarter-finals of season 3.0 and persisted in untelevised competitions until 2017, long past the heyday of other lightweight thwackbots. The most successful heavyweight melty-brain spinner is Nuts 2, which had chains connected to two "flail" weapons on either side of the machine. Nuts 2 ultimately finished joint 3rd (with Behemoth) in Series 10 of Robot Wars, ending the dominant run of Series 8 finalist and Series 9 champion Carbide along the way by breaking the robot's weapon chain.

Control bot weaponry
• 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 traps or attempt to toss the opponent onto its back. The lifter is typically powered by either an electric or pneumatic actuator. Lifters were most effective in older competitions, when self-righting mechanisms and high-power weaponry were less common. Two-time US Robot Wars and four-time BattleBots heavyweight champion Biohazard used an electric lifting arm to great effect. Lifting forks were utilized by Robot Wars series 2 champion Panic Attack and two-time BattleBots heavyweight champion Vlad the Impaler. Thanks to their narrow profile and simplicity, lifters are often combined with other weaponry. Sewer Snake, four-time RoboGames heavyweight champion, was a six-wheeled rammer with a lifting wedge. Modern BattleBots competitor Whiplash has seen success by combining a small spinning disc and lifting arm into a single weapon.

• Robot Wars series 3–4 champion Chaos 2, a British robot armed with a rear-hinged CO2-powered pneumatic flipping plate.

Robot Wars series 8 champion Apollo, with similar weaponry in 2017.

Flipper – Although mechanically resembling a lifter, the flipper uses much higher levels of pneumatic power to launch a lifting arm or panel upward at high acceleration similar to a catapult. 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.

• Clamper / Grabber – Clampers and Grabbers are an example of robots oriented around controlling and grappling their opponents rather than direct damage. They make use of an arm or claw that descends from above to secure the opposing robot in place on a wedge or lifting platform. In some clampers, the entire assembly may lift and carry the opponent wherever the operator pleases: these were called grapplers. Diesector, the superheavyweight champion of BattleBots 2.0 and 5.0, combined an electric clamper with smaller hammer arms. Middleweight BattleBots 4.0 runner-up Complete Control was another successful lifting clamper. Big Nipper, a horizontal grabber/lifter, won several untelevised championships in the UK after the end of Robot Wars. Bite Force won the 2015 season of BattleBots using a grabbing arm as its only form of weaponry, though in subsequent series its design was modified into a vertical spinner on a four-wheeled chassis.

Robot Wars series 5 (2002) champion Razer, one of the most successful crushers in the hobby.

• Crusher – Crushers are similar to grabbers, though they emphasize damage via one or more piercing hydraulic arms. Like flywheels, crushers can be separated into horizontal and vertical variants. Robot Wars Series 5 champion Razer was the first vertical crusher, and by far the most successful of its era. Another UK-built vertical crusher, Spectre, won the first King of Bots tournament in 2018, and has competed in BattleBots 2019 and 2023 under the name Quantum. Two-time Robot Wars Annihilator champion Kan-Opener was armed with a pair of horizontal crushing claws, one of the few examples of a successful horizontal crusher.

Hammers and axes

• Swinging an overhead axe, spike, or hammer at high speed onto your opponent offers another method of attacking the vulnerable top surface. The weapon is typically driven by a pneumatic or electric 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 trap.

• Interchangeable weaponry
It is increasingly common for robots to have interchangeable weaponry or other modular components, allowing them to adapt to a wide range of opponents and increasing their versatility; such robots are often referred to as "Swiss army bots", in reference to Swiss army knives. Arguably the earliest example was Robot Wars Series 1 contestant Plunderbird, which could change between a pneumatic spike and a circular saw on an extendable arm. Successful Swiss army bots include Robot Wars Series 6 champion Tornado, BattleBots 2016 runner-up Bombshell, and top-ranked US Beetleweight Silent Spring.[ Sometimes, robots that were not originally Swiss army bots have had their weapons changed or altered on the fly, typically due to malfunctions. In BattleBots 2015, Ghost Raptor's spinning bar weapon broke in its first fight; builder Chuck Pitzer then improvised new weapons for each following fight, including a "De-Icer" arm attachment which it used to unbalance and defeat bar spinner Icewave in the quarter-finals. Prohibited weaponry

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...)
• Fire (except in the new BattleBots and Norwalk Havoc)
• Explosives
• Un-tethered projectiles (except in BattleBots from 2018 season onwards)
• Entanglers (except in Robot Wars from series 10 onwards)
• 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. Competitions may also restrict or ban certain otherwise legal weapons, such as banning spinners and other high-power weapons at events where the arena is not able to contain these weapons, and the new Battlebots recently banned usage of carbon dioxide gas. A well-known example of this is the Sportsman ruleset.

Arena traps have also been granted exceptions to the list of prohibited weapons. Robot Wars in particular used flame devices both in the stationary traps and on one of the roaming "House Robots".
