Kan-Opener

"More bite than a Great White!"

- The robot's tagline

Kan-Opener is a competitor robot that competed in Series 5 to 7 of Robot Wars, plus the second series of Extreme and the 2016 series.

Although Kan-Opener has never progressed beyond the first round in any of its four main competition appearances, it did win two separate annihilators, one in Extreme 2 and the other in Series 7. This made Kan-Opener the only robot ever to defend its annihilator title.

Versions of Kan-Opener
In all appearances, Kan-Opener was a yellow robot, heptagonal in its first four versions, with two large horizontal crushing claws with hardened steel tips, driven by a 6.6 ton hydraulic ram, delivering 6.4 tonnes of force and capable of crushing car skins and chassis. It also featured two wet go-kart tyres, making it very quick and agile, and the robot had a total of four sets of jaws, all of which were interchangeable.

Kan-Opener's pincers sometimes posed a problem in that they would get lodged in their opponent's armour hence why Kan-Opener went out in the 1st round in the 7th Wars and lost one of its qualifiers for the 5th Wars despite pitting its opponent.

Kan-Opener A-spec (Series 5)
Kan-Opener A-spec, which competed in Series 5, was the only version of Kan-Opener to not be invertible. Instead, it featured a self-righting mechanism in the form of a sideways-opening bar, like that of Hypno-Disc. However, it proved unable to right the robot in battle. The robot's armour was pyramid-shaped, and was filled with holes in order to meet the weight limit.

Kan-Opener B-spec (Series 6)
From Series 6 onwards, Kan-Opener was much flatter and invertible. A battering ram was also added to the back of the machine in Series 6 and the armour was upgraded to Grade 4 titanium as well as having its ground clearance lowered.

Kan-Opener C-spec (Extreme 2)
Despite looking near-identical to the previous version of Kan-Opener, a brand new version of the machine entered the Annihilator of Extreme 2. Changes included an expanded array of interchangeable claws.

Kan-Opener D-spec (Series 7)
Series 7 continued the trend of Team Kan-Opener building a brand-new robot, once again looking much like the previous versions. New internals improved the robot's performance, and more armour was added to the section of the robot housing the pincers.

Kan-Opener J-spec (2016 series)
Tom and Andy Kane returned to enter a new version of Kan-Opener into the 2016 series of Robot Wars. This version of Kan-Opener was in fact owned by Jason Marston, but was lent to its original team for the sake of the competition, while Jason entered Thor. The robot now features a much more compact design, being much wider than its length, and features stronger armour than the version of Kan-Opener previously seen on TV. It also has stronger crushing claws, which have 12 tonnes of force at the tip of the pincers, making them the strongest crusher in the history of Robot Wars.

Series 5
The number 22 seed Atomic 2 was Kan-Opener's opponent in Round 1 of the Fifth Wars. Atomic 2 was very quick to flip over Kan-Opener, which had a self-righting arm fitted with a small glove. This self-righting arm failed to work, but Atomic 2 flipped Kan-Opener back onto its wheels. Kan-Opener was tossed onto its back again by Atomic 2 before it could use its weaponry, and pitted at the end of the battle. "Kan-Opener gets turned into a tin of beans!"

- Craig Charles, following Kan-Opener's defeat

Series 6
In Round 1 of Series 6, Kan-Opener faced Double Trouble, Demolition Man and Fluffy. It began stronger than in Series 5, hooking its claw around Demolition Man and grappling with the meter high robot, whilst beaching Double Trouble on top of it. However, Fluffy rushed into the fray, slamming and gouging several blows in Kan-Opener's side. "...and that has opened up a can of worms for those boys..."

- Jonathan Pearce

Kan-Opener lost all mobility, remaining pinned to Demolition Man, but Double Trouble released itself, slamming clean into Kan-Opener's side. Kan-Opener was separated from Demolition Man and counted out, before Double Trouble slammed it into another wall and Sir Killalot put it on the floor flipper. However, Kan-Opener had already done enough damage to Demolition Man to drag it out alongside it.

Extreme 2
Kan-Opener fought in the Annihilator competition of Robot Wars Extreme Series 2 with Major Tom, Thermidor 2, Typhoon 2, Raging Reality and Revenge of Trouble & Strife. It was flipped around by Raging Reality and Thermidor 2 in the first round and didn't do too much. During an attack from Typhoon 2, the tip of one of Kan-Opener's claws speared the cone spinner, stopping the Air Cadets machine from spinning, and it was unable to start spinning again. After Raging Reality flipped and immobilised Typhoon 2, the remaining five continued on.

In Round 2, Raging Reality broke down after Kan-Opener sank its claws into it. In the next round, Kan-Opener was through once more after Revenge of Trouble and Strife had been flipped and immobilised by Thermidor 2 before Kan-Opener pushed it down the pit. For the fourth round, Kan-Opener's claws had been greased up, so it was one of the more aggressive along robots with Thermidor 2. Major Tom finally dropped out after breaking down and getting severely damaged by the house robots leaving Kan-Opener and Thermidor 2 to go through to the Annihilator final.

It started off with Thermidor 2 trying to flip Kan-Opener but couldn't due to its large width. Kan-Opener then had Thermidor 2 in its claws trying to get it in the pit with it holding on well, then Kan-Opener grappled with Thermidor 2's wheel but Thermidor 2 got away. The two robots then found themselves in the CPZ getting attacked by Sergeant Bash and Shunt but they escaped. After Thermidor 2 tried flipping it over in a few failed attempts and Kan-Opener buried its claws into the lobster-like machine, Thermidor 2 was beginning to look damaged with holes and scratches spreading all over its armour. As the last 10 seconds of the fight started counting down, Kan-Opener slowly pushed Thermidor 2 towards the pit and with only four seconds to go, Kan-Opener managed to get it down claiming the title and becoming Annihilator champion, while setting the record for the longest bout to not go to a Judges' Decision.

Series 7
Kan-Opener fought against Barbaric Response, Big Nipper and Grim Reaper in Round 1 of the Seventh Wars. It started its opening round melee by getting its pincers to crush onto Barbaric Response's wheel guards, breaking them and crushing into the wheels. Whilst causing a large amount of damage, it couldn't pry the pincers out of Barbaric Response for the remaining duration of the battle. It edged Barbaric Response towards the pit but couldn't nudge Barbaric Response in, with the remaining time. It is disputed whether Kan-Opener had broken down by this point or whether it was simply unable to push Barbaric Response, it wasn't officially counted out and was included in the judges decision, which went against it. Kan-Opener was out in the first round once more.

"Heave, ho! Will it, go? Yes, no! It all goes to the Judges!"

- Jonathan Pearce on Kan-Opener nearly pitting Barbaric Response

After going out of Robot Wars in Round 1 for a 3rd time in a row, Kan-Opener was given the opportunity to defend its title in the Series 7 Annihilator contest along with Ripper, Flippa, Robochicken, Ewe 2 and Raging Knightmare, therefore being the only non-flipper in the Annihilator. The first round,as described by Andy Kane was "5 flippers and 1 crusher." Kan-Opener survived the first round, despite nearly getting flipped out the arena twice. Robochicken had been turned over by Ripper straight away and was unable to recover, allowing Kan-Opener to go through as a result. In spite of this, Kan-Opener collected an also immobile Ewe 2 between its claws, and pushed it into the pit, even though Robochicken was already eliminated. In the next round, Flippa failed to make it into the arena due to technical problems, putting Kan-Opener through by default. The third round battle started as a result, where Kan-Opener was able to avoid a contest of flippers that eventually resulted in Ewe 2 being stranded on its side. However, despite Ewe 2's immobility, Kan-Opener pierced the thin armour of Raging Knightmare, and dragged it towards the pit. Ewe 2 was already being counted out, when Kan-Opener held Raging Knightmare over the pit. Although Raging Knightmare hung above elimination, Kan-Opener could not free its claws from Raging Knightmare's armour until Ewe 2 had already been counted out. Kan-Opener still dropped Raging Knightmare in the pit regardless, making this the second battle in a row where Kan-Opener pitted a qualifying machine. It was perceived by Jonathan Pearce that Kan-Opener's team were very good friends with Team Roaming Robots. As a result, it was unsurprising in the fourth round that Kan-Opener teamed up with Ripper to dispose of Raging Knightmare. Like in the last round, Kan-Opener pierced the armour of Raging Knightmare, creating a huge hole, but struggled to release its prey. Kan-Opener held Raging Knightmare over the pit, and Ripper buffeted the back of Kan-Opener repeatedly to separate the two robots. Kan-Opener and Ripper would then meet in the final.

The Final started off with Ripper getting a series of flips in on Kan-Opener, but Kan-Opener was unharmed due to it being invertible. Ripper then found itself going round in circles and was unable to maneuver properly. Kan-Opener tested Ripper's mobility by driving away, proving that it was to become a champion once again. Kan-Opener then crushed in on Ripper's titanium side panels, noticeably bending them, causing Ripper's top armour to come off, all whilst Ripper was being counted out. At this point, Kan-Opener was smoking and could not be freed from Ripper, but as Ripper was immobilised anyway, Kan-Opener claimed the Annihilator title for a second time in a row. "When you go into the UK championship, you get one chance at it, and you kill. This Annihilator is a different game altogether - it's staying alive that counts"

2016 Series
Kan-Opener appeared in Episode 4. In the first round, Kan-Opener fought Gary Cairns for a second time, drawn against PP3D, as well as newcomers Apollo and Sweeney Todd. "I just want to see somebody's poor robot being picked off the teeth of your robot!"

- Dara Ó Briain

As Kan-Opener had entered the arena directly in front of the pit release button, they immediately reversed and opened the pit. It then targeted the dangerous spinner of PP3D, knocking it away, but Kan-Opener was tossed by Apollo, though Kan-Opener pushed the inverted Apollo in return. Once it grabbed hold of PP3D, it did not let go, driving themselves over the floor flipper, which overturned the locked pair, and the two were only freed when Apollo flipped both at once. Kan-Opener drove back over the floor flipper, and was thrown over by it, but returned to grab PP3D. However, it was at this point that Apollo launched Kan-Opener across the arena, knocking out its safety link upon landing, eliminating it from the competition alongside Sweeney Todd.

Robot Wars Live Events
Kan-Opener J-spec debuted at the Robot Wars live event at Portsmouth 2015 where it did reasonably well in the friendly fights. It also participated in the Robot Wars World Championships 2015, held in Colchester. In the first round, Kan-Opener was the last robot left standing - Rybot could not self-right after it was flipped by Maelstrom, the latter breaking down after a combined attack from Kan-Opener and Tough as Nails. Both robots qualified, but Kan-Opener also lodged Tough as Nails in the arena wall, immobilising it. However, Kan-Opener broke down within the opening moments of its second round fight, leaving Gravity and Tiberius to fight alone.

Outside Robot Wars
As of 2012 there have been nine versions of Kan-Opener (taking a letter sequence as opposed to a numerical sequence), with a further two in the build stage. Both of them (G and H) were sold to Team Bud after Team Kan-Opener retired from the event circuit. Tom Kane has also become a member of Team Bud, adding Kan-Opener G and H to Team Bud's armada of robots. Kan Opener G has been kept by Jason (previously a member of Team Bud) and Kan Opener H has been sold to Mario of Team KODOX. In 2015, Jason built Kan-Opener J which was a complete departure from previous models in shape, but still retains the same design concept in being invertible with the crushing jaws.

Kan-Opener H-spec in original shape participated in the Bronebots 2016 competition in Moscow. After this event Marco from VHS-Robots took over Kan-Opener H-spec.
