"Hedgehogs are spiky and Edge Hogs are even worse!"
Jonathan Pearce

Edge Hog (also spelled Edgehog) was competitor robot that fought in Series 6 and 7 of Robot Wars, as well as the New Blood Championship in the second series of Robot Wars Extreme. It lost in the first round in both its main series appearances, but reached its Heat Final in the New Blood Championship, losing to Thor.


Edge Hog in Series 7

Edge Hog was a box wedge-shaped robot armoured in polycarbonate and titanium with aluminium and titanium side panels. Its main weapon was a pneumatic titanium axe initially capable of striking 20-25 times at 106 mph. The axe doubled as a self-righting mechanism and was accompanied by a small front wedge which was intended to get underneath opponents. While its axe was potent and the robot possessed fair pushing power, Edge Hog required precise accuracy to cause damage, and the Series 7 version of Edge Hog notably lacked a baseplate.

In Series 6 and the Extreme 2 New Blood Championship, Edge Hog featured a grey, black and orange colour scheme, which was changed to silver and blue for its Series 7 appearance.


Edge Hog's name is a pun on 'hedgehog'. It could have also been named after the robot's creator, Stephen Egerton, who claimed that its weakness was his own driving.

The Team[]

Edge Hog was entered by Edge Mecs from Macclesfield in Cheshire. The captain was Stephen Egerton, the only team member present in all of Edge Hog's appearances. Stephen was joined by three different team members in each of his appearances, these being Chris Prest in Series 6, William Ashton in Extreme 2 and James Steele in Series 7.

The insides of the Series 4 version of Edge Hog

An earlier version of Edge Hog, an invertible wedge shape armed with interchangeable circular saw and flipper weapons, attempted to enter Series 4. It fought Big Pants in its qualifier, but was left with mobility issues early on after suffering a blow from Big Pants's axe.

"The battle began and Edgehog proved to be a bit more nimble than BP. The commentator kept on shouting 'We want to see the axe' right in my ear, so as soon as I was in range I pulled the trigger. There was a yell from the commentator and the audience as they saw the axe fire just over-shooting Edgehog's back. A second firing and the axe cleaved into the side-pod of Edgehog. It quickly became clear that although there was still movement from my opposition, he had suffered from the blow."
— Team Panda website, on Edge Hog's Series 4 qualifier against Big Pants[2]

With Big Pants unable to retract its axe, both robots were soon pitted by the House Robots, and the fight ended in a draw. Neither Edge Hog or Big Pants successfully qualified for Series 4 as a result.

Edge Hog also attempted to enter Series 5, this time armed with an axe, but failed to qualify again after losing to Crushtacean.

At the Series 6 qualifiers, Edge Hog was drawn against Biothan, Chompalot and Rampage. Rampage was forced to withdraw before the battle, leaving the other three to fight. Edge Hog and Chompalot both impressed the judges' enough to qualify, whilst Biothan was not selected to compete.

Robot History[]

Series 6[]

In its first appearance, Edge Hog faced the 12th seed and Extreme Warriors International champion Tornado, returning robot Terror-Bull, and fellow newcomer Inshredable.

It began by attacking and being lifted by Terror-Bull. Edge Hog went for Terror-Bull again, before being shoved around a few times by the experienced Tornado. Next, Edge Hog got underneath Inshredable and attacked it, before being shunted by Tornado again. As a result of this, Edge Hog found itself in Matilda's CPZ, and the House Robot attacked it from the rear with her flywheel. Edge Hog took considerable damage to its main back panel, got stuck in reverse, and in the process hit the pit release button. Refbot attempted to free Edge Hog, but failed so it counted the robot out.

Extreme 2[]

Edge Hog participated in the New Blood Championship in Robot Wars Extreme 2. In the first round, it was drawn against Chip and RT 81.

Edge Hog had a lucky break in its first round battle, as it fought head-to-head with Chip but repeatedly missed, and also came into contact with the hammer of Mr. Psycho, and under this pressure, Edge Hog became immobilised on one side. Yet despite Edge Hog's immobility, RT 81, which had been out of the action until that point, was pushed into the arena centre by Mr. Psycho, right next to Edge Hog. Edge Hog sunk its axe into RT 81's tyre, continuing to attack it until the robot caught fire. Eventually Edge Hog could not help but drive itself into Mr. Psycho's new CPZ, sustaining a hammer blow. Edge Hog attempted to strike Mr. Psycho with its own axe, unable to move away, but the house robots pushed Edge Hog into the arena side wall, where its axe became stuck on the arena wall, and eventually into the CPZ. Although Edge Hog would never leave this CPZ, Refbot was already counting out RT 81, putting Edge Hog through to the second round.

Before the second round, Edge Hog had problems with its drive system, but these were fixed before its fight with Hell's Teeth.

This was one of its best performances, as it hammered Hell's Teeth repeatedly with its axe until the invertible machine broke down. Each of Edge Hog's blows punched straight through Hell's Teeth's armour, with its most notable blow puncturing one of the bot's tyres. Having won the battle, Edge Hog attacked Dead Metal and caused damage to Sergeant Bash. Edge Hog was then attacked by the house robots on the flame pit, but went through anyway.

In the Heat Final, Edge Hog faced Thor, who had been in its heat in Series 6.

Both robots missed repeatedly with their weapons, hitting the arena floor more times than they hit each other, although Edge Hog's successful attacks left less of an impact than the attacks of Thor. Edge Hog was then pushed into Sir Killalot's CPZ where it was dragged out, spun around, and thrown onto its back. Edge Hog managed to self-right but didn't move afterwards, which resulted in Refbot counting it out and eliminating it from the New Blood Championship.

Series 7[]

In the first battle of Series 7, Edge Hog faced former champion and 8th seed Panic Attack, its fellow Welsh compatriot Mega Morg, and the returning Spin Doctor.

Edge Hog began tentatively, driving into the back of Mega Morg, then axing the top of it. Edge Hog continued to try and attack Mega Morg from its rear, but achieved nothing. By this time, Panic Attack had turned Spin Doctor onto its side, eliminating it. Edge Hog now turned its attention to the former champions. As Refbot counted Spin Doctor out, Mega Morg flipped, then righted Edge Hog. Panic Attack went for the axe-wielding robot next, lifting it and releasing it by the Flame Pit. The two Welsh robots then ganged up on Edge Hog, both lifting it up, and pitting it.

Between Series 6 and 7, Edge Hog found great success at the Dutch Robot Games in 2003, with a string of victories allowing it to finish in second place[3]. In the first round, Edge Hog defeated Mute and Hard, then won against Lizzard and Toecutter 2 in the second round by pitting Lizzard and immobilising Toecutter 2[4]. Remarkably, Edge Hog then won its third-round battle over the soon-to-be second and third place robots in Robot Wars later that year, earning a win over Tornado and Storm 2. Edge Hog also won its semi-final by pitting Bigger Brother and winning the Judges' decision over Tsunami, before finally being pitted by Tough as Nails in the Grand Final.

Edge Hog after Series 7

Edge Hog later entered the 2005 UK Championship, losing its only battle to Ripper. Edge Hog was then bought by James Baker in 2005 and was heavily revised, internally and externally with new batteries, speed controllers, radio system, pneumatics system, armour and a new axe. The team fought with Edge Hog in the 2006 UK Championships and fought well against Weird Alice, but lost to Big Nipper and Hades. Edge Hog later entered the 2007 and 2008 Championships with moderate success, but subsequently retired

The team, nowadays known as Team GlitterBomb, used Edge Hog was to compare dimensions during the build of GlitterBomb. Edge Hog's axe mechanism was then used in GlitterBomb after the team did not have enough time to design and build their own mechanism.
