Changes: Bladed axes

Revision as of 14:18, 28 January 2019

"We hated it (Killerhurtz's spiked axe). We decided to add this broad blade axe so it wouldn't get stuck, it would just keep digging at them..."

— John Reid after defeating Panic Attack

Bladed axes are a type of overhead weapon found in Robot Wars. The first robot to feature this weapon was House Robot Shunt in Series 1, who would earn fame for his diamond-edged (later titanium) axe in later series.

The first competitor robot to feature a bladed axe was Killerhurtz in Series 2, although it was later replaced with its more famous spiked axe. Other notable robots with this weapon type include its successor, Terrorhurtz, The Steel Avenger, and Thor from Series 8 onwards. Both Terrorhurtz and Thor are also the most successful, reaching the Grand Final and placing fourth in Series 6 and 8 respectively.

Definition

Tomahawk bladed axe — Tomahawk's bladed axe in Series 7

Bladed axes typically feature an axe head with a blade featuring a much larger surface area than a spiked axe, which aim to provide a larger area of attack. They are specialised to chop, pound, bend, hack and shake components and armour loose rather than pierce through them, and are among some of the most common types seen in everyday usage - for example, fireaxes which are used to chop wood. Bladed axes come in various shapes and sizes, from fireaxe-style chopping blades, as originally used by Killerhurtz, to curved blades with a spiked tip, as seen on The Steel Avenger, and even double-headed blades as used by Terrorhurtz and the Series 3 competitor Shell Shock.

Advantages and Disadvantages

Advantages

Mr speed squared vs thor 2 — Thor pierces M.R. Speed Squared's armour

Steel Avenger axes Shredder Evolution — The Steel Avenger scored over Shredder Evolution by striking and dragging it with its axe

Reptirron Flame Pit — Terrorhurtz drags Reptirron the Second onto the Flame Pit in Series 6

A powerful bladed axe can serve as an efficient cross between a spiked axe and a hammer, being able to cause both external and internal damage with equal efficiency. Terrorhurtz demonstrated this effectively in its Series 6 Semi-Final fight against Spawn Again, and Thor punched holes through M.R. Speed Squared's armour and hacked off Shockwave's scoop in their Series 8 Head-to-Heads.
With their large surface area, bladed axes are the most effective type of overhead weapons for use as a self-righting mechanism, provided that there is sufficient power behind the axe to achieve this. Terrorhurtz and Thor demonstrated this capability quite effectively several times.
Successful axe blows tend to score well on control and aggression, in the event of a Judges' decision. This is perhaps best shown in Steel Avenger's victory over Shredder Evolution in Series 7, and in Thor's victory over Shockwave in their Head-to-Head battle in Series 8.
As with spiked axes, the leverage offered by a bladed axe can allow robots equipped with them to drag and push opponents around if the axe head becomes embedded in them. Both Terrorhurtz and The Steel Avenger demonstrated this tactic at various moments across both of the show's runs.
Alongside hammers, bladed axes were more readily available than most other types of weapons, as they could be purchased rather than manufactured, although purchased weapons proved ineffective outside of earlier series.

Disadvantages

Vulture pillow — The 'pillow' used by Vulture to counter blows from Terrorhurtz's axe, comprising of HDPE blocks and other materials

Thor vents gas — Thor vents CO₂ as its pneumatics system malfunctions against TR2

Thor CO2 Magnetar — Thor's CO₂ billows out following a direct hit from Magnetar

TMHWK broken axe — During its *World Series* battle against Terrorhurtz, TMHWK's axe arm snapped in half as a result of metal fatigue and a powerful flip from Matilda's tusks

Opposing teams were welcome to modify their designs before a battle in an attempt to nullify axes, by applying additional armour to the top of their robot. For example, in Series 10, both Vulture and Rapid gained extra layers of armour for their head-to-head battles against Terrorhurtz, in order to protect vital components from getting damaged.
Most bladed axes only functioned in one specific direction - usually forwards - compounding the accuracy issues present in this and all other overhead weapon types. Terrorhurtz's axe is a notable exception, as it was designed to be double-headed in order to strike from both the front and back of the machine.
If pneumatically-powered, bladed axes can also fail to operate if the weapon is low on CO₂, or if the pneumatics system is damaged or malfunctioning. This would also remove the robot's ability to self-right, which was apparent in the defeats of Terrorhurtz, Glitterbomb and Thor throughout Series 8 and 9, with all of them not being able to self-right at various stages due to problems with their pneumatics systems or their CO₂ supplies freezing in cold temperatures.
Pneumatic axes may have their mechanisms exposed to attacks from crushers, or vertical spinners if upside-down. This was most notably shown in Thor's battle with Magnetar in Series 10, where a well-timed attack from Magnetar ruptured Thor's CO₂ supply.
The shaft of a bladed axe may often get damaged or even bent. This was best shown by Thor in Series 9, where Jason Marston had to turn the shaft around to try and bend it the right way, however he did note that continued attempts at this would cause the axe to break due to metal fatigue.
- The effects of metal fatigue were vividly demonstrated by TMHWK's axe arm during the first episode of Robot Wars: World Series, which bent and snapped in half in its Head-to-Head following attacks from Terrorhurtz and Matilda.
In some cases, a bladed axe head can cause the wielder and its opponent to become stuck together, requiring separation if the axe is embedded in an opponent and cannot retract on its own. In both of its encounters with Vulture in Series 10, Terrorhurtz was unable to separate itself from the former, requiring the House Robots to prise both competitors apart. Unsuccessful attempts to retract an axe can also use up a limited CO₂ supply, reducing the effectiveness of the axe once the robots are separated.

Bladed axes vs Spiked axes

While a spiked axe focuses on piercing armour, bladed axes focus on causing internal damage by shaking components loose. For example, when the axes of Terrorhurtz and Iron-Awe 2 struck the armour of Barber-Ous 2, the spiked axe of Iron-Awe 2 created outward damage by piercing the plastic armour, while the bladed axe of Terrorhurtz caused significant internal damage and immobilised Barber-Ous 2.
Although bladed axes are not immune to becoming stuck in a robot's armour (e.g. Terrorhurtz vs Vulture, Series 10), they are far less likely to become stuck in a robot's armour or the arena floor than a spiked axe. This would also allow the axe weapon to strike multiple times more quickly, if it can more easily retract from a robot.
Bladed axe heads suffer less recoil damage when striking impenetrable armour, as spiked axe heads may blunt or break when failing to pierce armour. For this reason, bladed axes were far more prominent in the reboot of Robot Wars, where hardened steels proved difficult to break through.

-*Bladed axes were initially less effective as a knock-out weapon than a spiked axe, as they did not put out the kinetic energy into a point needed to damage vital components in the same way that spiked axes could, and required a lot more power to do so. [[Shunt]] and Terrorhurtz were the only two robots to immobilise another with a bladed axe in the original series of ''Robot Wars'', and it was not until the show's hiatus that other robots with bladed axes became more effective over time.
-*A bladed axe largely specialises in knocking internal components loose, and is not as effective at causing visible damage as its spiked counterpart. As a result, it can become ineffective against robots with strong armour and chassis.
