Self-inflicted immobilisation

Self-inflicted immobilisation
Killerhurtz "didn't see the pit", eliminating itself from Series 3 by driving into it

A Robot Wars competitor which eliminates itself either accidentally or deliberately (via several different ways) is considered to have achieved a self-inflicted immobilisation. This differs from hostile immobilisations (which are inflicted by opposing robots), malfunctions (in robot design or engineering) and hazard immobilisations (which are inflicted by House Robots or arena hazards, such as the Floor Flipper and spikes).

Self-inflicted immobilisations are often referred to throughout the show as a robot committing suicide.

Definition

The key term in deciding if an immobilisation has been self-inflicted or not is to determine whether there has been an avoidable error. An avoidable error cannot be a result of issues relating to the robot's design or engineering, nor can it arise from circumstances such as taking on a difficult Gauntlet route or a certain opponent in battle. They must be concise, specific events which directly cause an immobilisation. Examples are listed below:

Arena Hamper

Often, robots became immobilised due to contact with parts of the arena (not including hazards), usually by hitting a wall or getting stuck in the floor.

Self-Inflicted

YES: The Demolisher took the corner of its third lap too tight and flipped itself over, an avoidable error

• In the Stock Car Trial, The Demolisher crashed into a wall at top speed, flipping itself over. With no other robot involved, and The Demolisher's own avoidable action responsible for its immobilisation, this is considered a self-inflicted immobilisation.
• Similarly, when both Kat 3 and The Steel Avenger got their axes stuck in the arena floor, this was an avoidable error and had it solely cost them their battles, it would have been designated here.

Not Self-Inflicted

NO: Vector of Armageddon became stuck on a Gauntlet ramp because of its design, not because of an error on its driver's behalf

• Contrarily, when Vector of Armageddon attempted the Gauntlet in Heat D of Series 1, it became stuck attempting the second ramp. The reason for the immobilisation was that Vector of Armageddon's ground clearance was too low. Therefore, the robot's design meant that it would never have been able to traverse that second ramp. Getting wedged was not an avoidable error, and this is therefore not a case of self-inflicted immobilisation. Although it can be argued that taking the ramp at all was an error, Vector of Armageddon succeeded in negotiating the first ramp, and nearly all robots had succeeded in taking the second one. Therefore, it is not reasonable to believe that taking the ramp would have ended in immobilisation.
• When Psychosprout drove forward in the Labyrinth trial in Series 1, Heat E, it collided with REALI-T and rolled back to the start. This immobilisation was primarily caused by the collision between both robots,

Fire

YES: Terror-Bull chose to repeatedly drive onto the flame jet, an avoidable error costing its chance of progressing to the Heat Final in Series 4

When a robot breaks down after catching fire - usually through driving itself over or near a flame hazard - it is deemed to have become immobilised by fire.

Self-Inflicted

• Terror-Bull chose to light its tail on fire in its Series 4 battle with Raizer Blade. This turned out to be a costly decision as Terror-Bull's motors burnt out.

Not Self-Inflicted

NO: Technophobic caught fire after getting pushed onto the Flame Pit by Pitbull

• Most immobilisations by fire, although in the same method, are not self-inflicted. Technophobic burst into flames in Series 3, but only after it was pushed onto the Flame Pit by Pitbull during their second-round battle. Being pushed onto the Flame Pit was not Technophobic's choice, and was therefore not an avoidable error.
  
  
  

Recoil

Although most thought to be classed as a malfunction, recoil occurs when a robot's weapon malfunctions or contains too much power/energy within an attack, causing the robot to immobilise itself through this.

Self-Inflicted

YES: Both halves of Gemini flipped themselves over without any influence from their opponent, Napalm 2

• In its Extreme 1 Mayhem battle against Napalm 2, one half of Gemini flipped itself onto its back, where its wheelie bar pinned it off the ground. If a robot puts itself into a position where it becomes immobilised, it is considered self-inflicted.
• PP3D's battle-stopping attack on Cherub in their Series 9 Head to Head was not only powerful enough to send its opponent spinning into the wall (resulting in Cherub getting flipped over and immobilised), but also break a gearbox plate supporting one of its own drive motors. This left it unable to drive in a straight line when the battle was restarted, its disc also being disabled due to an ejected removable link. If a robot damages itself during an attack and becomes immobilised as a result, the immobilisation is considered self-inflicted.

Not Self-Inflicted

NO: Inverterbrat was pinned off the ground by its own lifter, which malfunctioned and became stuck underneath the robot

• Inverterbrat's flipper became wedged beneath the robot and beached it off the ground when trying to flip The Creature. Although this would seem like a self-inflicted immobilisation, there was no avoidable error, as the flipper in fact malfunctioned to pin it in place. Therefore, this was a malfunction.
• In trying to flip S.M.I.D.S.Y. out of the arena during its Series 5 Heat Final, Chaos 2 flipped itself over, and was unable to right itself. Whilst this could be seen as a self-immobilisation, it was later revealed that Chaos 2 could not self-right after S.M.I.D.S.Y. damaged its flipper cover before this moment. It could be argued that, as S.M.I.D.S.Y. played a direct role in preventing Chaos 2 from recovering, it could not be seen as a self-inflicted immobilisation.

Pitted

Whenever a robot falls into the Pit of Oblivion through any means, it is classified as having been pitted.

Self-Inflicted

YES: Cassius 2 ended up in the pit largely as a result of a misjudged attack on Pussycat

YES: Wild Thing drove over the descending pit in Series 6 after it had already been activated

• Most infamously, when Killerhurtz drove across the arena and into the pit in Series 3, there was no possible contact with Cerberus which could have caused the pitting, with Cerberus still on the other side of the arena as it happened. John Reid's actions were, therefore, an avoidable error and Killerhurtz's pitting is considered a self-immobilisation.
• In a different take on this issue, when Cassius 2 attempted to pit Pussycat in Heat M of the same series, Cassius 2 charged too quickly in its attempt to do so, overshooting the edge of the pit and falling in itself. Despite Pussycat being involved in the tussle, Cassius 2 made an avoidable error by putting too much acceleration into its push. Therefore, where a robot pits itself whilst attempting to pit another, it is considered a self-inflicted immobilisation.
• After the introduction of a designated pit release button, Shredder, Major Tom and Wild Thing 2 all lost fights after driving over the pit as it was descending. Whilst there was often a delay in the pit descending after it was pressed, it is still considered an avoidable mistake as the pit had already been activated by another robot.

Not Self-Inflicted

NO: Eric had already been stranded over the pit by King Buxton before driving itself in. Note that Eric's left wheel is hanging over the pit

• Any instance where a robot is pushed, flipped or dropped into the pit by another competitor or a House Robot. These are actions beyond the robot's control, and are considered hazard immobilisations.
• If a robot is directly put into a position by an opponent where it falls into the pit, it cannot be reliably considered as a self-inflicted immobilisation. For example, when Eric drove into the pit whilst trying to push King Buxton in, this had come as a result of King Buxton pushing Eric towards the pit and getting both robots stranded with half of their wheels suspended over the pit. Whilst Eric did technically pit itself seconds later, it had only done so due to actions caused by its opponent which prevented it from being able to drive away from the pit in the first place. Had Eric been able to pull itself away from the pit and then fall in, it would have been classed as a self-inflicted error. A similar example occurred when Panic Attack fell into the pit whilst trying to push 101 in, as 101's own attempts to free itself diverted Panic Attack's movements.

NO: Stinger was diverted into the pit by Mace 2

• Stinger and Corkscrew both lost battles after being deflected into the pit by Mace 2 and Kronic 2, respectively. Whilst in both cases the pitting may have been considered an avoidable error, it is impossible to tell whether their trajectory changes were due to their opponents' attacks (which would make it a hostile immobilisation) or due to Stinger and Corkscrew's own actions. With such doubt, these cannot be considered self-inflicted immobilisations.

Stranded

To be stranded, a robot has to have entered a position where it cannot move. The most common cases of getting stranded are through driving onto grilles (Series 1), into the Pit of Oblivion (see Pitted), or off platforms in the Sumo trials or side competitions (Series 2, Series 4).

Self-Inflicted

YES: Dantomkia wedged itself underneath the angle grinder during its Series 6 Semi-Final battle against S3, contributing to its eventual immobilisation

• During Dantomkia's battle with S3, Dantomkia became stuck underneath an angle grinder after driving into it. It is impossible to tell whether the impact, the angle grinder, S3's disc, or Refbot's attempt to push it free were responsible for the immobilisation. However, irrespective of the actual cause, Dantomkia's immobilisation was directly influenced by it driving into the angle grinder in the first place. Therefore, if a robot takes terminal damage whilst caught in a position it gets itself stuck in, it is considered a self-inflicted immobilisation.

Not Self-Inflicted

NO: Mute was flipped out of the arena through a combination of its own flip and Firestorm 5's

• Any instance where a robot is pushed into the aforementioned hazards and gets stuck, or pushed off the platform in Sumo competitions. The former circumstances are considered to be hazard immobilisations, such as Tornado impaling one half of Gemini onto a wall spike in Series 4.
• During Mute's semi-final battle with Firestorm 5, as Firestorm 5 went to flip an inverted Mute out of the arena, both robots fired their flippers at the same time, resulting in Mute being flipped out of the arena. Whilst it is entirely possible that Mute could have thrown itself out of the arena on its own, in this scenario it was directly aided by its opponent, preventing it from being self-inflicted.

Floor Flipper

Especially since Series 8, it is possible for a robot to become immobilised by driving onto and being flipped by the Floor Flipper. This is especially possible if the affected robot is unable to run inverted or has no self-righting mechanism.

Self-Inflicted

YES: Chompalot drove itself onto the Floor Flipper without any interference from Gabriel, resulting in its defeat as it was unable to self-right afterwards

• Chompalot's defeat to Gabriel in Series 8 was solely attributed to Chompalot driving itself onto the Floor Flipper, being thrown across the arena, and left unable to self-right upon landing on its side near the arena wall.
• Similarly, Foxic backed onto the Floor Flipper during its Series 9 Group Battle, and was effectively immobilised after its lifting arm failed to work at all.

Not Self-Inflicted

NO: Dantomkia was directly pushed onto the Floor Flipper by TR2

• Any instance where a robot is pushed onto the Floor Flipper by another and is flipped over. A notable example is TR2 pushing Dantomkia onto it during their Series 8 Heat Final, an action which was beyond Dantomkia's control. Such actions are considered to be hazard immobilisations.
• In the original series, the Floor Flipper was only generally used to throw immobilised competitors across the arena, after they had been placed there by a House Robot or their opponent(s). As competitors had already been eliminated before being flipped, these instances do not count as self-inflicted immobilisations.

Series 9

Rapid lies on its back after its flipper jams open

Foxic backs onto the Floor Flipper, eliminating itself from Series 9

Wyrm bumps itself into immobility

Rusty throws itself over

Robot	Definition	Battle	Notes
Rapid	Recoil	Heat A, Head-to-Heads	After getting flipped over by Aftershock, Rapid tried to self-right, but it somersaulted over Aftershock and hit the arena floor with its flipper. This jammed the flipper open as Rapid landed on its back, leaving it unable to right itself.
PP3D	Recoil	Heat B, Head-to-Heads	PP3D's impact on Cherub sent the latter hurtling into the wall and immobilised it; however in doing so, a gearbox plate supporting one of PP3D's drive motors broke, leaving it spinning in circles and technically immobile when the battle was restarted.
Foxic	Floor Flipper	Heat C, Group Battle	After performing strongly in its Group Battle, Foxic reversed over the Floor Flipper and was thrown onto its back. As its lifting arm was missing a retaining bolt, it was inoperable, leaving Foxic unable to self-right after being flipped.
Wyrm	Arena Hamper	Heat D, Group Battle	Wyrm drove straight into the wall, causing both of its drive chains to break loose on contact. This initially eliminated Wyrm from Series 9, although it was later reinstated when Frostbite was too badly damaged to continue the Head-to-Head round.

A faulty TMHWK reverses into the pit

Robot	Definition	Battle	Notes
The Swarm	Floor Flipper, Pitted	Heat A, Group Battle	Two parts of the clusterbot immobilised themselves during the battle. Pinza drove over the Floor Flipper and was thrown onto its back, unable to self-right. Skye later drove straight into the open pit.
Apocalypse	Fire	Heat A, Group Battle	After getting thrown into Sir Killalot by Apollo, Apocalypse got stuck over the Flame Pit while trying to drive away from the House Robot, having already suffered chassis damage which caused one of its drive chains to become dislodged. These factors resulted in Apocalypse immobilising itself, before being promptly attacked by Sir Killalot and left to catch fire.
Crackers 'n' Smash	Fire	Heat B, Robot Redemption	In an attempt to retreat from Sir Killalot, Crackers ended up on the Flame Pit, immobilising itself completely. Because Smash was already thrown out of the arena by Big Nipper, it meant that both parts of Crackers 'n' Smash were officially deemed immobile and the whole robot eliminated.
Androne 4000	Floor Flipper	Heat D, Group Battle	Androne 4000 drove over the Floor Flipper while gripping Concussion, and became immobile upon landing. Concussion, unable to break free as a result, was also counted out with it.
Androne 4000	Floor Flipper	Heat D, Semi-Final	After having the hydraulics system for its crusher ruptured by Nuts 2, Androne 4000 swerved over the Floor Flipper, resulting in it being thrown over and left unable to self-right; its second defeat involving the hazard.
Expulsion, Sabretooth, Thor	Pitted	10 Robot Rumble	All three robots drove themselves into the pit at some point during the battle.
Iron-Awe 6	Floor Flipper	10 Robot Rumble	Iron-Awe 6 drove onto the Floor Flipper during the Fog of War it had activated itself; recurring issues with its flipper prevented it from self-righting once turned over.
