  • AR500 - A hardened variation of steel which is Abrasion Resistant. The number dictates its hardness, with AR400 and AR500 commonly named in the construction of BattleBots competitors. Some robots, such as SawBlaze, use the even harder AR600 steel for their weapons.
  • Application - The online form used to confirm a team's intention of competing in an upcoming season of BattleBots.


  • Basement Tapes - A term given to the unaired battles often released to Facebook Supporters before being released publicly at a later time. These fights often have considerably less effort put into their editing and sometimes do not even have commentary. For the 2021 season, the unaired fights were posted to YouTube the Sunday after the main episode.
  • BattleBook - A part of the BattleBots website reserved for registering for and scheduling Proving Ground battles.
  • BattleBox - The enclosed arena filled with hazards in which all BattleBots fights are held.
  • Behind the Bots - A podcast dedicated to talking about BattleBots and other robot combat events where fans can submit their listener questions on Facebook to builders and producers of the show.
  • Billet - A large chunk of material from which a chassis can be cut from in one large piece. Billets are often stronger than chassis constructed from individual parts as they do not need fasteners like bolts to hold them together, but are often very expensive. An example of a billet chassis is that of DUCK! from the Discovery seasons of BattleBots.
  • Bite - In reference to a robot's weapon, the bite or purchase is the degree of engagement given weapon has for the transfer of kinetic energy. A greater bite indicates higher efficiency in a spinning weapon, thus stronger hits. It's measured as the maximum depth of opponent insertion into the arc of a spinning weapon given its radius, RPM, geometry, and number of teeth as well as the collision speed of the interested robots.[1][2]
  • Botopsy - The name given to a deep dive into the condition of a robot post-fight, often highlighting key damage which contributed to a robot's loss. The term Botopsy Report was initially used for a special segment throughout the Comedy Central run, later being reintroduced as a recurring feature of Science Channel's World Championship III airings. In 2023, the term was reintroduced once more for the tournament bracket of World Championship VII, in the Road to the Giant Nut segment.
    • Botopsy is a play on the word 'autopsy', which is a medical examination done to determine a cause of death.

  • Box-Rush - Derived from the term 'bum-rush', the act of charging directly at your opponent from the very start of the fight to overwhelm them and prevent robots armed with spinning weaponry to reach top speed.
  • Brazil Wheels - The general name given to wheels molded from vulcanized rubber, as seen on the likes of Whiplash, Malice, Black Dragon and from 2022 onward, SawBlaze. Though heavy and typically expensive compared to alternative options, they are also incredibly durable. As their name suggests, they were initially produced by Brazilian teams before gaining more widespread popularity.
  • Bye - More often seen in untelevised events, a bye signals where a robot's opponent was unable to make the arena for one reason or another, and therefore forfeited their place in the battle. As such, the unwithdrawn robot automatically advances. Sometimes, as in the case of robots such as HellaChopper in World Championship II, a replacement is found for the withdrawn robot instead of handing out a win.


  • CAD - Stands for Computer Aided Design and describes the use of producing a three-dimensional model of a robot or specific parts using computer software. Common examples of CAD software include Autodesk Inventor, Fusion360, OnShape and SolidWorks.
  • Classic Era - A term referring to any form of robot combat event or show prior to BattleBots returning to television in 2015. Within the realms of BattleBots itself, the term often refers to Seasons 1.0 to 5.0 on Comedy Central.
  • Configurations - An important part of the modern sport, a configuration is an offensive or defensive setup to suit an upcoming opponent and give a team the best chance of winning a specific fight. This can come in the form of a specific weapon (see Interchangeable Weaponry), additional or minimal armor, wedges, plows, forks or wedgelets at the front, and so on. Many configurations will come with their own advantages and disadvantages, with sacrifices being made to keep the robot within a limit.
  • Controlbots - The category given to robots which rely on active weaponry which prioritise controlling their opponent by pushing, lifting or flipping it as opposed to causing damage.
  • Crab-Walking - A term used to describe the limited mobility of a robot after it has lost drive to at least one of its wheels, tracks or legs on one side. The term comes from the way in which crabs move side-to-side due to the way their legs are jointed.


  • Death Hum - The name given to the noise made as a spinning weapon gets up to speed. This is due to air being pushed away in gusts, which produces a humming noise that typically gets louder as a weapon gets faster.
  • Desperado Tournament - A mid-season tournament held during World Championship III and IV where eight robots would be selected to fight in a knockout bracket. The winner of the bracket, irrespective of their win/loss record to date, would be guaranteed a place in the tournament bracket.
  • Destruct-A-Thon - The BattleBots live event held in Las Vegas, Nevada between televised World Championships, which also consist of Proving Ground battles.

  • Fight Night - The competition format used from World Championship III onward, Fight Night sees competing robots get up to four fights (three in the World Championship V and World Championship VI) to impress a selection committee. Every robot will earn a win/loss record and this, as well as their strength of schedule, will determine a Top 32 (Top 16 in the 2018 and 2019 seasons) to advance to the main knockout bracket.
  • Floor Spinner - A spinning disc integrated into the BattleBox floor during the Comedy Central era which, when active, aimed to disrupt robots that drove over it.
  • Forks - Long triangular strips of metal often added to the front of a robot with the intention of sliding in underneath an opponent to win the ground game. Some may be serrated to snag a robot once it is on top of them, or smooth instead. Forks can be static, hinged or connected to a shaft driven by a powerful motor and gearbox in order to lift opponents.


  • Giant Nut - Sometimes shortened simply to 'the Nut' and dating back to the very first BattleBots sanctioned events, the Giant Nut is the ultimate trophy awarded to the winner of a main competition.
  • Ground Game - The fight to have the lowest leading edge on a wedge or forks, in order to get underneath an opponent and either control them around the BattleBox, take them to the arena hazards or inflict damage with a primary weapon.
  • Gyro - Often used interchangeably with 'gyro-dancing', this describes the effect of a robot lifting up on one side due to the gyroscopic forces in play from its vertical spinning weapon, or internal flywheel. Though this occurs with many vertical spinners, robots such as Minotaur and the flywheel flipper Blip utilize gyro-dancing as a way of celebrating a win.


  • Haaspital - A portmanteau of 'Haas' and 'hospital', the on-site CNC machining area in the pits during BattleBots seasons which are dedicated to manufacturing new and replacement parts for teams between fights. The Haaspital received a dedicated segment during Episode 8 of World Championship VI.
  • Hammer Saw - A variation on existing weapons which consists of a downward-spinning disc on the end of an arm which swings like a traditional axe or hammer bot to hit an opponent. Hammer saws have been popularized by later versions of SawBlaze and Skorpios, as well as Jäger's Arm Muscle and the most recent build of Blacksmith. 2020 season runner-up Whiplash has also been known to attack from the rear with its lifting arm at full stretch.
  • HARDOX - A brand name of steel which is harder to source, but commonly seen in the construction of British robots.
  • Hellraisers - A now-defunct BattleBox hazard which raised multiple panels in the center of the arena floor to create ramps and mess with robots looking to win the ground game. After causing the center of the arena to sink during the 2019 season, the hellraisers were not integrated into the new BattleBox floor for World Championship V onward.
  • Hero Shot - Professional photoshoots of robots taken early in the first few days of a season's filming schedule, often with red or blue background lighting.

  • Interchangeable Weaponry - The ability to swap weapons out depending on an opponent. Very similar to the wider term 'configurations', but solely concerning weapons. Notable examples include Ribbot with their vertical spinner, bar spinner, horizontal undercutter and lifting arm weapons, and Ultimo Destructo with its vertical spinner, horizontal bar spinner, hammer and lifter.


  • Judges' Decision - The way in which a winner is determined if all robots are still active at the end of the three minute fight. A panel of three judges will each vouch for a winner based on the categories: Damage, Aggression and Control.
    • Unanimous Decision - a Judges' Decision where every judge votes in favor of the same robot, irrespective of their scoring.
    • Split Decision - a Judges' Decision where at least one judge has voted differently to the others. An odd number of judges are always present to ensure this cannot be split evenly.

  • lbs - Otherwise known as pounds, this is the most common unit of weight concerning US combat robots. In the modern era, heavyweight BattleBots competitors are allowed to weigh up to 250lbs, with walkers permitted an upper limit of 500lbs. Robots armed with spinning weapons cannot have a spinning mass exceeding 80lbs in weight, as of the 2020 season.
  • LiPo - Short for Lithium Polymer, LiPos are the most common type of batteries seen in BattleBots competitors due in part to the power they offer for such little weight, compared to heavier alternatives such as the lead acid batteries seen in many Comedy Central era competitors.


  • Magic Smoke - A term which alludes to the thick, white smoke produced when a lithium polymer (LiPo) battery is damaged or shorts within a robot. This is often, but not always, followed by fire and requires crew to enter the arena, extinguish the fire and remove the smoke from the BattleBox.
  • mAh - Short for milli ampere-hours (or milliamp hours), mAh is a unit which measures the capacity of a battery. Typically, a battery with a larger mAh value will be able to power components for longer than a battery with equivalent specifications, but a lower mAh value. 1000mAh is the same as 1Ah.
  • Main Event - The final and most hyped-up battle of the episode, often between two of the best robots in the competition.
  • Mauler Dance - Also known as 'doing a Mauler' named after its pioneer, this term refers to a robot, typically a shell spinner, appearing to breakdance when unbalanced as it tries to use its spinning weapon to self-right. This has since been emulated by other robots too, including Captain Shrederator in its 2021 season exhibition match against HUGE.
  • Meltybrain - The name given to a unique feature with robots such as Blade Runner and Herr Gepoünden whereby the robot can sit and spin in place, while also maneuvering around the arena. Although meltybrain robots were typically limited to smaller weight classes, the idea was popularized with the Robot Wars competitor Nuts 2 and was trialed with BattleBots applicants such as ZAP and Dizzy.
  • Minibots - Smaller robots weighing up to 20lbs which accompany a heavier robot and serve as either a distraction for their opponent, or to play an active part in the fight.
  • Multibots - Not to be confused with Minibots, these are BattleBots competitors comprised of two or more smaller robots which, when combined, adhere to their division's weight limit. Notable examples include Pack Raptors, The Four Horsemen, Gemini and Jäger, and are also known in some scenes as 'Clusterbots'.

  • Walkers - Robots which use legs with Robots such as the Comedy Central version of Son of Whyachi were originally referred to as a 'walker', before rules were enforced on what constituted a method of locomotion that qualified for the weight bonus. As such, early versions of SOW are considered 'shufflers'. Sometimes called 'true walkers' to denote the distinction between them and shufflers, examples include the 2020 season build of Chomp, later versions of Red Scorpion and Gloomweaver.
  • Wildcard - A competitor selected to advance in a BattleBots tournament despite losing their previous fight. Wildcards were only used in the first two reboot seasons on ABC, as they were deemed unnecessary for the Fight Night format.
  • WOPR - Introduced in 2015, the WOPR was the unofficial name given to the system used to automate various BattleBox hazards including the Killsaws and Screws. This also allowed for the latter to reverse automatically if any debris was detected preventing them from rotating. Its name derives from the 1983 film WarGames and stands for War Operation Plan Response.
  • Wubs - A type of shock isolator consisting of rubber or a similarly flexible material sandwiched between metal which aims to absorb the shock of a big hit and prevent anything attached to it bearing the brunt of the impact.
