'''Vertical flywheels''' were a type of rotating weapon. They were typically quite large and thin and were capable of damage on a large scale. Whilst typically unsuccessful in the UK, robots with this weapon became the German and Dutch Champions, and [[Cyclone (Extreme Warriors)|Cyclone]] won an annihilator in ''[[Robot Wars: Extreme Warriors]]''.

'''Vertical flywheels''' are a type of heavy rotating weapon which first became prominent in later series of ''[[Robot Wars]]''. The first robot to be equipped with such a weapon was [[Torque of the Devil]] in Series 1, while the most successful UK Series competitors to be equipped with one include fourth-place finishers [[X-Terminator]] (Series 7) and [[Aftershock]] (Series 9), Series 5-6 Semi-Finalist [[S3]] and ''[[Robot Wars: Battle of the Stars|Battle of the Stars]]'' co-champion [[Kadeena Machina]]. House Robot [[Matilda]] was also equipped with a rear-mounted vertical flywheel from Series 5/Extreme 1 onwards, replacing her chainsaw in the UK Series and being made interchangeable with it in ''[[Robot Wars: Extreme Warriors]]'' and ''[[Nickelodeon Robot Wars]]''.
   
This weapon was typically more successful in BattleBots, with the widely famous ''Nightmare'', who inspired a number of UK Robots. House robot [[Matilda]] initially had a chainsaw but changed to a 27&nbsp;kg flywheel after Series 4, although the flywheel was said to be interchangeable with the chainsaw in ''[[Robot Wars: Extreme Warriors]]''.
+
Whilst vertical flywheels were not as common or initially as famous as their [[Horizontal flywheels|horizontal counterparts]] in the UK Series, robots with this weapon type also enjoyed considerable success in international versions of ''Robot Wars''. Dutch Series 2 Champion [[PulverizeR]] and German Series champion [[Black Hole]] were both equipped with these flywheels, as was US competitor [[Cyclone (Extreme Warriors)|Cyclone]], which won the Annihilator in the second season of ''Extreme Warriors''. They also enjoyed some success in the lower weight categories, with [[Argh!]] winning the Extreme 2 Featherweight Championship by using a vertical flywheel to devastating effect.

*A ''' flywheel''' is a comparatively heavy spinning disc weapon that spins at high speeds. To cause damage, one or more "teeth" are welded onto or integrated into certain places along the disc's circumference, in order to gouge and tear large sections off of opponent's armour or destroy vital components.

*Compared to the horizontal flywheel, these flywheels are mounted vertically, and are intended to strike the bottom edges and sides of other robots.

'''Advantages'''
 
'''Advantages'''
*Vertical weapons were capable of doubling as [[flipping weapons]], even capable of throwing an opponent [[out of the arena]], as [[X-Terminator]], Cyclone and Matilda showed.
+
[[File:S3Plunderbird.jpg|thumb|S3 shreds Plunderbird 5]]
*They often targeted the underside of a robot, the weakest point on the design. This allowed for maximum damage.
+
[[File:X-Terminator_vs_Killer_Carrot_2.png|thumb|X-Terminator tosses Killer Carrot 2 out of the arena]]
*They proved effective against flippers; buckling the wedge of flipper meant that it was neutralised - unable to negotiate ground clearance. [[X-Terminator]] showed this in its Semi Final fights against [[St. Agro]] and [[Bulldog Breed]].
+

  +
[[File:Big_Nipper_Eruption_1.jpg|thumb|Big Nipper causes damage to Eruption as it lands after a flip]]
  +
*Like the horizontal type, vertical flywheels are capable of inflicting substantial amounts of damage to their opponents, tearing into and ripping off sections of armour plating as well as destroying their chassis, wheels and weapons. [[S3]], [[PulverizeR]], [[259]], [[Cyclone (Extreme Warriors)|Cyclone]], [[Black Hole]], [[Kadeena Machina]] and [[Aftershock]] are among the most prominent examples.
  +
*Vertical flywheels can also double as [[flipping weapons]]. Most robots equipped with them - famously 259 and Aftershock - are capable of throwing opponents over as well as damaging them at the same time.
  +
**Some are even capable of throwing other robots [[Thrown Out of the Arena|out of the arena]], as demonstrated by [[Matilda]], Cyclone, the Series 7 version of [[X-Terminator]] and the Series 10 iteration of [[Big Nipper]].
  +
*They often target the underside of a robot, usually considered its weakest point, allowing for maximum damage to its chassis and wheels/tracks. S3 particularly destroyed [[Plunderbird|Plunderbird 5's]] chassis, armour and wheel mounts during its first ever battle, and Kadeena Machina was able to shred [[Dee|Dee's]] wheel off.
  +
*Vertical flywheels also deliver more powerful blows for the same amount of stored kinetic energy as their horizontal counterparts, as robots equipped with them are braced by contact with the arena floor when they hit opponents. This enabled robots such as 259, Kadeena Machina and Aftershock to remain stable even while making repeated attacks on their opponents.
  +
*They are especially effective against robots equipped with wedges and flippers, effectively neutralising them by buckling the wedge/flipper plate and rendering them unable to negotiate the wielder's ground clearance. [[X-Terminator]] demonstrated this in its Series 7 Semi-Final fights against [[St. Agro]] and [[Bulldog Breed]].
  +
*Very rarely, this type of flywheel can also double as a [[Self-righting mechanism|self-righting mechanism]], being able to 'kick' robots back onto their wheels if the flywheel hits the arena floor or walls. Aftershock was the only ''Robot Wars'' competitor to demonstrate this capability.
  +
*If a robot wielding a vertical flywheel is thrown upside-down, the flywheel is still capable of causing damage to nearby opponents if it lands weapon-first on them. Aftershock and Big Nipper, for example, were still able to damage [[Eruption]] with their discs as they landed on top of the latter during their Series 9 Grand Final Group Battle and Series 10 Heat Semi-Final respectively.

*The design was often hard to combine with the invertible design, especially large flywheels such as the likes of [[259]]. This meant that often, a robot with this weapon needed an additional srimech.
+
[[File:Black_Hole_pitted.png|thumb|After being flipped over by Philipper 2, Black Hole's discs lost their effectiveness, and were eventually unable to prevent it from being pitted]]
*Also, the effectiveness of the weapon when inverted was often decreased due to many flywheels spinning in only one direction. This was shown when [[Black Hole]] was overturned by [[Philipper|Philipper 2]] and its discs span towards the ground, causing Black Hole to jump upwards upon striking its opponent.
+
[[File:Kadeena_Machina_gyrodance.jpg|thumb|The gyroscopic forces of Kadeena Machina's disc resulted in the robot frequently lifting itself onto one side whenever it tried to turn with the weapon spinning]]
*In a clash between horizontal and vertical heavy rotating weapons, a vertical will typically come off second best, as shown in the clash between [[Fluffy]] and 259.
+
*Vertical flywheels are often hard to combine with invertible designs except for [[axlebots]], especially larger ones like those used by [[259]] or [[Cyclone (Extreme Warriors)|Cyclone]]. This often meant that a robot with this weapon type either required an additional srimech (e.g. [[Cedric Slammer]]) or had to adopt smaller flywheels (e.g. Black Hole, the Series 8 and 10 incarnations of Big Nipper).
*They have a narrower range of attack than [[Horizontal flywheels]].
+
*Also, the weapon's effectiveness can often be decreased when inverted, due to many flywheels spinning in only one direction. This problem especially affected Black Hole in its [[European Championship]] battle against [[Philipper|Philipper 2]], with its discs spinning towards the ground once the robot was flipped over and causing it to jump upwards upon striking Philipper 2's armour.
  +
*Vertical flywheels have a narrower attack range than their horizontal counterparts, limiting their precision. Black Hole circumvented this through using two flywheels attached to the same axle, each mounted on either side of the machine.
  +
*The gyroscopic forces of a vertical flywheel can adversely affect the robot's manoeuvrability, making it difficult for it to turn when the weapon is spinning. Additionally, they could also lift the robot up onto one side or even cause it to overturn when turning left or right. Though commonly displayed by more modern spinners such as [[Kadeena Machina]], [[Aftershock]], [[Pulsar]] and the Series 10 version of [[Big Nipper]], early instances of this happened to [[Matilda]] during the first heats of ''[[German Robot Wars]]'' and the [[Robot Wars Extreme: Series 2/New Blood Championship|Extreme 2 New Blood Championship]], as well as Black Hole in its aforementioned European Championship battle.

Vertical flywheels are a type of heavy rotating weapon which first became prominent in later series of Robot Wars. The first robot to be equipped with such a weapon was Torque of the Devil in Series 1, while the most successful UK Series competitors to be equipped with one include fourth-place finishers X-Terminator (Series 7) and Aftershock (Series 9), Series 5-6 Semi-Finalist S3 and Battle of the Stars co-champion Kadeena Machina. House Robot Matilda was also equipped with a rear-mounted vertical flywheel from Series 5/Extreme 1 onwards, replacing her chainsaw in the UK Series and being made interchangeable with it in Robot Wars: Extreme Warriors and Nickelodeon Robot Wars.

Whilst vertical flywheels were not as common or initially as famous as their horizontal counterparts in the UK Series, robots with this weapon type also enjoyed considerable success in international versions of Robot Wars. Dutch Series 2 Champion PulverizeR and German Series champion Black Hole were both equipped with these flywheels, as was US competitor Cyclone, which won the Annihilator in the second season of Extreme Warriors. They also enjoyed some success in the lower weight categories, with Argh! winning the Extreme 2 Featherweight Championship by using a vertical flywheel to devastating effect.

DefinitionEdit

TorqueOfTheFlywheel

The first vertical flywheel on Torque of the Devil

  • A flywheel is a comparatively heavy spinning disc weapon that spins at high speeds. To cause damage, one or more "teeth" are welded onto or integrated into certain places along the disc's circumference, in order to gouge and tear large sections off of opponent's armour or destroy vital components.
  • Compared to the horizontal flywheel, these flywheels are mounted vertically, and are intended to strike the bottom edges and sides of other robots.

Advantages and DisadvantagesEdit

  • Like the horizontal type, vertical flywheels are capable of inflicting substantial amounts of damage to their opponents, tearing into and ripping off sections of armour plating as well as destroying their chassis, wheels and weapons. S3, PulverizeR, 259, Cyclone, Black Hole, Kadeena Machina and Aftershock are among the most prominent examples.
  • Vertical flywheels can also double as flipping weapons. Most robots equipped with them - famously 259 and Aftershock - are capable of throwing opponents over as well as damaging them at the same time.
  • They often target the underside of a robot, usually considered its weakest point, allowing for maximum damage to its chassis and wheels/tracks. S3 particularly destroyed Plunderbird 5's chassis, armour and wheel mounts during its first ever battle, and Kadeena Machina was able to shred Dee's wheel off.
  • Vertical flywheels also deliver more powerful blows for the same amount of stored kinetic energy as their horizontal counterparts, as robots equipped with them are braced by contact with the arena floor when they hit opponents. This enabled robots such as 259, Kadeena Machina and Aftershock to remain stable even while making repeated attacks on their opponents.
  • They are especially effective against robots equipped with wedges and flippers, effectively neutralising them by buckling the wedge/flipper plate and rendering them unable to negotiate the wielder's ground clearance. X-Terminator demonstrated this in its Series 7 Semi-Final fights against St. Agro and Bulldog Breed.
  • Very rarely, this type of flywheel can also double as a self-righting mechanism, being able to 'kick' robots back onto their wheels if the flywheel hits the arena floor or walls. Aftershock was the only Robot Wars competitor to demonstrate this capability.
  • If a robot wielding a vertical flywheel is thrown upside-down, the flywheel is still capable of causing damage to nearby opponents if it lands weapon-first on them. Aftershock and Big Nipper, for example, were still able to damage Eruption with their discs as they landed on top of the latter during their Series 9 Grand Final Group Battle and Series 10 Heat Semi-Final respectively.

Disadvantages

Black Hole pitted

After being flipped over by Philipper 2, Black Hole's discs lost their effectiveness, and were eventually unable to prevent it from being pitted

Kadeena Machina gyrodance

The gyroscopic forces of Kadeena Machina's disc resulted in the robot frequently lifting itself onto one side whenever it tried to turn with the weapon spinning

  • Vertical flywheels are often hard to combine with invertible designs except for axlebots, especially larger ones like those used by 259 or Cyclone. This often meant that a robot with this weapon type either required an additional srimech (e.g. Cedric Slammer) or had to adopt smaller flywheels (e.g. Black Hole, the Series 8 and 10 incarnations of Big Nipper).
  • Also, the weapon's effectiveness can often be decreased when inverted, due to many flywheels spinning in only one direction. This problem especially affected Black Hole in its European Championship battle against Philipper 2, with its discs spinning towards the ground once the robot was flipped over and causing it to jump upwards upon striking Philipper 2's armour.
  • Vertical flywheels have a narrower attack range than their horizontal counterparts, limiting their precision. Black Hole circumvented this through using two flywheels attached to the same axle, each mounted on either side of the machine.
  • The gyroscopic forces of a vertical flywheel can adversely affect the robot's manoeuvrability, making it difficult for it to turn when the weapon is spinning. Additionally, they could also lift the robot up onto one side or even cause it to overturn when turning left or right. Though commonly displayed by more modern spinners such as Kadeena Machina, Aftershock, Pulsar and the Series 10 version of Big Nipper, early instances of this happened to Matilda during the first heats of German Robot Wars and the Extreme 2 New Blood Championship, as well as Black Hole in its aforementioned European Championship battle.
"We didn't do a vertical spinner because the gyroscopic effect makes steering very difficult."
