Crushtacean

"A crab-bot with insane snipping powers"

- Robot Wars: The Official Handbook

Crushtacean was a robot that competed in Series 5-7 and Series 9 of Robot Wars, as well as the second series of Robot Wars Extreme. It reached the Heat Final in Series 5, losing to Wheely Big Cheese, but failed to reach that stage afterwards, as it fell in the second round in Series 6 and the first round in Series 7 and Series 9. It also competed in the second series of Dutch Robot Wars under the name Krab-Bot, and reached the Grand Final before losing to Philipper 2 there.

Team Crushtacean captain Ian Visser was originally from South Africa and the team represented the country in international competitions. Crushtacean finished runner-up to Firestorm 4 in the Commonwealth Carnage in Extreme 2, and came joint third with Tough As Nails in The Third World Championship.

Its name was inspired by "the crab-bot", described in Arthur C Clark's science fiction novel, Rendezvous with Rama. It was also a pun on Crustacean, the group of arthropods to which the crab belongs.

Design
Crushtacean was a large disc-shaped robot armed with a pair of claws, designed to look like a crab. It was invertible, and was two-wheel driven either way up, with four wheels total. Notably, Crushtacean's wheels were almost completely above the shell of the robot, and its claws also had two castors attached to each. Crushtacean was armoured in 12mm thick aerospace aluminium. It featured a 1m turning circle and a 4cm ground clearance. The aerial sat exposed at the top of the robot, and as a result Crushtacean sometimes suffered from radio interference. The front of Crushtacean was lined with LEDs, to give the robot 'eyes'. The robot was painted silver throughout its UK series appearances, and purple and silver when it competed in Dutch Series 2 as Krab-Bot.

Crustacean was originally planned to be redesigned for the Sixth Wars, with hydraulic claws suggested by George Francis. However, due to the complexity of the hydraulic mechanisms, the original robot was brought back largely unchanged.

When Crushtacean returned in Series 9, it boasted top speeds of 20mph, increased from the former 12mph, and was painted red on the robot's claws and sides. This red paint is polyurethane, making Crushtacean the only robot to use this kind of paint; and is said to be very tough and durable. This polyurethane paint was used to protect the claws from spinners, possibly in response to Crushtacean's loss to Supernova from the Seventh Wars.

Armament
Crushtacean's main weapon was a pair of claws capable of a 300-500kg grip strength. Crushtacean was unique, however, in that rather than being controlled by a button or a joystick, its claws were operated by a pair of gloves. The gloves had sensors that would respond when the wearer (usually Dominic Visser) would open or close his hands. As a result, Crushtacean's claws moved in tandem with its controlling roboteer, allowing Crushtacean an unprecedented level of dexterity and reflexiveness amongst pincers.

In The Sixth Wars, Crushtacean won the award for Most Original Entry, thanks to its unusual technology.

The Team
"It started a few years ago while we were watching one of the Robot Wars programmes on BBC2. My son Dominic, then aged six, said 'Can you make one of those?' Of course, I couldn't resist. Funnily enough, a barrister friend named Richard Hartley was having exactly the same conversation with his six-year-old, Howard. So we decided to join forces - and came up with Crushtacean."

- Ian Visser on the origins of Crushtacean

The team captain was Ian Visser, who was inspired to build the robot on the suggestion of his son Dominic. He built the robot along with his friend Richard Hartley. Richard Hartley was the weapons operator in Series 5, but did not appear after this, with Dominic becoming the new weapons operator.

For Series 7 and Extreme 2, the third team member was Ian's daughter Michaela, but she did not return for Series 9, where Dominic Visser returned at the older age of 23 to become the main driver of the robot.

Qualification
Work on the robot started in December 2000, and the robot took around 500 hours to complete, being finished in August 2001, just in time for the Series 5 qualifiers, where they fought and defeated Edge Hog. As a result, Crushtacean directly qualified for the Fifth Wars, also qualifying for Series 6 and 7.

The team also applied to enter Series 8 of Robot Wars, but the filming clashed with a time when team member Dominic had to be at university, so the team withdrew their application, and instead entered Series 9, where Crushtacean was accepted to compete.

Series 5
Crushtacean made its first appearance in the wars against Robochicken-Evo in the first round of Heat H.

Crushtacean moved forwards, turned, but turned too far and span on the spot. As Robochicken-Evo tried to get underneath and flip it, Crushtacean tried to reverse away, but Robochicken-Evo still had its flipper under the claw, so flicked Crushtacean up with it. Crushtacean span, tried to drive away, but span on the spot again. Robochicken-Evo tried to get its flipper under Crushtacean again, but Crushtacean turned around, and Robochicken-Evo missed its flip. Sergeant Bash came in, and Crushtacean drove away as Sergeant Bash blocked Robochicken, then reversed back into Robochicken-Evo. Robochicken-Evo fired the flipper, but missed as it was not under Crushtacean. Crushtacean tried to grab Robochicken-Evo by the flipper, but Robochicken-Evo fired the flipper, knocking Crushtacean off the flipper. Crushtacean reversed, but as it drove back at its opponent, it span on the spot again, and Robochicken-Evo drove straight into Sergeant Bash. Crushtacean reversed at Robochicken-Evo, but Sergeant Bash was between the two and pushed Crushtacean away. Crushtacean span again, and as Robochicken-Evo closed in, drove up the arena, before turning. It got side-on against Robochicken-Evo, grabbed it by the flipper, and pushed it up the arena. "...So Crushtacean, a sort of space age, space module type robot out there in the arena..."

- Jonathan Pearce comments on Crushtacean's unique technology

Crushtacean let go, and Robochicken-Evo got its flipper under it and pushed it to the top of the arena, but because the flipper was only under the claws, Crushtacean was merely lifted onto the top of Robochicken-Evo. Robochicken-Evo tried to close the flipper, but Crushtacean was under it, until Crushtacean reversed away, straight into Refbot. However, Sir Killalot pulled Robochicken-Evo into the CPZ, and crushed one of its eyes. "...and this is a very difficult battle to gauge, who is going to topple the balance of ... urgh, the natural habitat, down there? Robochicken is pecked by Sir Killalot, and the boggling eyes are still intact, but only just. "Fowl" tackle by Killalot, surely!"

- Jonathan Pearce as Sir Killalot drags Robochicken-Evo into the CPZ and crushes its eye

Sir Killalot dropped Robochicken-Evo, it span, then reversed out of the CPZ, straight at Crushtacean, flipping it over. Crushtacean managed to get under the flipper again, and pushed Robochicken-Evo into the CPZ. Crushtacean reversed out of the CPZ as Sergeant Bash came in and trapped Robochicken-Evo. Crushtacean opened the pit, whilst Robochicken-Evo reversed out of the CPZ, but straight into Sir Killalot. Fortunately for Robochicken-Evo, Sir Killalot merely went carried straight to its CPZ. Crushtacean was waiting by the flame pit, and as Robochicken-Evo tried to get under it, Crushtacean turned at the right moment, getting the flipper in its claw. Crushtacean tried pushing Robochicken-Evo, but as it turned, it lost its grip on the flipper. Robochicken-Evo got its flipper under one of Crushtacean's claws and pushed it up the arena, but Robochicken-Evo turned and Crushtacean reversed off the flipper. "Crushtacean turning away once again. The crab dosen't want to plumb the depths of the dark pool at the bottom of our pit of doom."

- Jonathan Pearce

However, Crushtacean started spinning again, allowing Robochicken-Evo to push it into the claw of Sir Killalot, which picked it up and span it around. Time ran out, and the battle went to the Judges.

The judges decided, on a 2-1 split decision, that Crushtacean had won. "Very close, good bunch of guys, good little robot they built, flipped us over, but that's what we were designed for."

- Richard Hartley on the battle and his opponent

In the second round of the heat, Crushtacean was up against the far more experienced 15th seeds Behemoth. "It's our first time here, but a bit of world domination will do us fine, thanks!"

- Ian Visser during his introduction

Crushtacean started by moving forwards, then spinning, and Behemoth got behind it and pushed it, but Crushtacean turned, getting against the side of Behemoth. Behemoth tried to get under Crushtacean, but Crushtacean drove away, down the arena and into the pit release button. "Crushtacean going straight for the pit release, they obviously feel they have to get this over and done with quickly, because if it goes the distance, Behemoth, they fell, will chalk up too many points against them."

- Jonathan Pearce

Behemoth axed Crushtacean, but failed to puncture it. Behemoth lifted Crushtacean up, but then dropped it and Crushtacean reversed away up the arena, reversing into Refbot. As Behemoth drove after Crushtacean, it fired its axe at thin air. This proved to be a mistake, as they did not pull the axe back when they got under Crushtacean, so failed to get under it, and Crushtacean dodged the scoop as it lifted. Crushtacean pushed against Behemoth's side and scoop, and Behemoth lifted it up by the claw that was pushing against the scoop. However, Crushtacean slipped off the scoop and got under the scoop. As Crushtacean pushed the seeds back, Behemoth closed the scoop, which caused it to flip itself on its back. Crushtacean pinned Behemoth against the angle grinder. "What a good drive by Crushtacean!"

- Jonathan Pearce as Behemoth is toppled against the angle grinder

Behemoth kept opening the scoop to try and get down, but Crushtacean had it pinned. Crushtacean turned Behemoth away from the wall and pushed it into the pit. "What a famous victory from Crushtacean!"

- Jonathan Pearce

Crushtacean had achieved a shock win against the seeds.

In the Heat Final, it was up against the 10th seeds Wheely Big Cheese. "It's your first time in Robot Wars, the Semi-Finals are just within ... grabbing distance!"

- Phillipa Forrester to Ian Visser

Crushtacean had a cheese grater tied to its claw for this battle, which Ian Visser jokingly called his "secret weapon". "We've got the "greater cheese", he's got the cheese grater!"

- Roger Plant

Crushtacean drove forwards, but span on the spot again. Wheely Big Cheese tried to get under it, but Crushtacean drove past before it could do so. However, it drove into the arena wall, and Wheely Big Cheese got under it. It failed to flip its opponent, but Crushtacean reversed into Dead Metal. Dead Metal grabbed Crushtacean, but before he could cut into the wheels, Wheely Big Cheese flipped the House Robot, allowing Crushtacean to escape. "And the cheese in this trap is not to catch a mouse, it's to catch a crab."

- Jonathan Pearce

Wheely Big Cheese briefly had its flipper open, resting on an angle grinder, and Crushtacean pushed it against the angle grinder, with Dead Metal pushing against Crushtacean. It tried to grab the seeded machine, but Wheely Big Cheese reversed away, and Crushtacean had accidentally grabed onto the angle grinder. Crushtacean opened the claws, but drove into the wall. Wheely Big Cheese got under it, but Crushtacean reversed off the flipper. It tried to turn to fight, but span on the spot twice. "Whatever happens in the next few moments, it's been a worthy challenge."

- Jonathan Pearce on Crushtacean

Wheely Big Cheese tried to get under it, but Crushtacean drove off, so Wheely Big Cheese missed. Crushtacean opened the pit, then drove up the flipper, allowing Wheely Big Cheese to flip it over. After this, Crushtacean reversed, but then stopped. Wheely Big Cheese got under it again, flipping it. Crushtacean reversed, only to stop again, and Wheely Big Cheese got another flip in. This flip caused the arial to fall off Crushtacean. "They cannot now transmit to Crushtacean, either its maneuverability or its weaponry will have gone, maybe both!"

- Jonathan Pearce

Wheely Big Cheese fliped Crushtacean up again, then flipped it towards the pit, before nudging it in. "And what a bold effort it was by Crushtacean."

- Jonathan Pearce

At the end of the series, Crushtacean was nominated for the Most Promising Newcomer Award, but lost out to Fluffy. "Crushtacean, looked mean. A lean machine, and Behemoth felt the full force of these newcomers."

- Jonathan Pearce reading through the nominations

Series 6
Crushtacean's first round battle for the Sixth Wars was against three newcomers; Dantomkia, Doctor Fist and Mr Nasty. "Tough to crack, the shell 12mm thick aerospace aluminium, the two claws capable of a 300 kilo pressure grab, but the aerial's just between the eyes, and that could leave this crab scuttling sideways!"

- Jonathan Pearce

Crushtacean initially had some control problems, driving towards the CPZ instead of its opponents. Dantomkia drove at Crushtacean, but before it could get under it, Crushtacean drove at Mr Nasty, pushing it around the arena. Mr Nasty managed to escape down the arena, but then stopped, as Crushtacean had cut off the aerial. Dantomkia got under Crushtacean and pushed it across the arena. "...Dantomkia comes in underneath that ground clearance of 4cm, it is an Achilles heal for Crushtacean."

- Jonathan Pearce

Crushtacean managed to reverse off the front of Dantomkia could flip, but Dantomkia soon got back under it and flipped it onto the arena wall in the CPZ. Sir Killalot came in, picked Crushtacean up, and span around with it. Despite hanging Ian Visser's machine over the arena wall, Sir Killalot dropped Crushtacean back on the arena floor. Crushtacean was moving, but one of its wheels looked deflated, and Crushtacean struggled to move in a straight line. Dantomkia flipped Crushtacean over, and Crushtacean stopped moving, one of its claws being fully open, holding the robot off the floor. "Is there still movement? There is from the pincer."

- Jonathan Pearce

Dantomkia pushed Crushtacean down the arena and tried to flip, but failed to overturn Crushtacean as the flipper was only under the claw. As Doctorr Fist was counted out, Crushtacean only moved a little, and Dantomkia easily got under it, ramming it down the arena and flipping it onto the pit release button. Sir Killalot nudged Crushtacean off the button with his claw, but Crushtacean had stopped moving. However, Mr Nasty was counted out, having been immobile longer. The House Robots pitted the eliminated robots, and Crushtacean and Dantomkia were through. In Round 2, Crushtacean was up against the 5th seeds and former UK Champion Chaos 2. Before the battle, the team discovered one of the claws was not working, and the team had not brought a spare motor, so they were forced to fight with only one claw. "We burnt out a motor, one of the drive motors, I don't know how, ... and so, we only discovered that very late, and now there's not much time left to sort it out."

- Ian Visser

Chaos 2 started by charging at Crushtacean, getting under it, but Crushtacean quickly got off the flipper. Chaos 2 tried to get under it, but Crushtacean drove across the arena. It turned around, and pushed Chaos 2 back with its claws. Chaos 2 used its flipper, but because of the size of Chaos 2 and the width of Crushtacean's claws, the attack from George Francis' machine left both machines balanced on their sides. Crushtacean landed on its tyres first, and pushed Chaos 2 back towards the arena wall. Chaos 2 flipped Crushtacean, but although it succeeded in throwing the crab, the attack also threw Chaos 2 backwards onto an angle grinder. "Ooh, Chaos is on its side! This really would be a turn-up for the books because Crushtacean is not fighting at its full capability, we know that!"

- Jonathan Pearce

Chaos 2 tried getting itself down with a flip, but despite moving off the angle grinder, was still stuck on its side. After a pause where the flipper did not close, Chaos 2 fired the flipper again, getting back on its wheels. Chaos 2 attempted to come onto the attack by meeting Crushtacean front on again and pushing it back, but it only suceeded in lifting up its opponent. Chaos 2 tried to flip Crushtacean again, but Crushtacean visibly dug its claws into Chaos 2 on its second flip. "What a great fight this is! Digging down on the front spikes of Chaos 2 to gain purchase on the arena floor."

- Jonathan Pearce as the two machines lock horns again

Crushtacean pushed Chaos 2 into an angle grinder, but Chaos 2 was able to push back, and finally managed to turn Crushtacean over with a flip, nearly turning itself over forwards, and followed this successful attack up with another flip soon after. Crushtacean, now on the back foot, decided to activate the Pit Release bumper. However, Crushtacean's plan backfired, as it began to violently swerve around close to the arena hazard, before reversing itself down into the Pit. "And they crab sideways, back down into the pool, and the Pit of Oblivion! After all that!"

- Jonathan Pearce after Crushtacean pitted itself

Crushtacean was resulted as a result.

At the end of the series, Crushtacean was given the Most Original Entry Award.

Extreme 2
Crushtacean came back for Extreme Series 2 and took part in the Commonwealth Carnage representing South Africa. In the opening round melee, Crushtacean went up against Panic Attack representing Wales, Cerberus representing Cyprus and Terror Turtle representing Canada. Crushtacean started very well by chasing down and soon grabbing hold of Cerberus before opening the pit and throwing the machine from Cyprus down. With only Panic Attack and Terror Turtle remaining, Crushtacean caused damage to the rear framework of the turtle. Later, Sir Killalot grabbed Terror Turtle in his claw, so Crushtacean slipped around the House Robot's backside and cut his hydraulic cables, after which he did not move again. On a Judges' decision, Crushtacean qualified alongside Panic Attack.

In the second round, Crushtacean then faced the Scottish Corkscrew. The fight started with Corkscrew doing its usual tactic of running away to get up to speed, and this meant that Crushtacean was sent reeling by the first contact between the two. However, Crushtacean then managed to chase the Scottish robot into the arena wall, stopping the spinning rim, allowing Crushtacean to grab hold of the blades. Crushtacean then waltzed Corkscrew into the pit release before pushing it down. Crushtacean also fell into the pit itself, but the victory stood.

The final was against the English Firestorm 4, the English representative.

Team Crushtacean's fears were proven true, as their robot was hounded by Firestorm, its high ground clearance constantly being exposed by the flipper. Crushtacean was pushed into Dead Metal, which narrowly missed with an attempt to slice through the wheels on top of Crushtacean. Still in the CPZ, Firestorm flipped Crushtacean into the House Robot to put Crushtacean onto its side, and then flipped it into the arena wall. Another well-aligned flip from Firestorm left Crushtacean stranded on its side, where it was left alone and counted out. Crushtacean was not attacked by the House Robots, which were occupied by Firestorm's attacks, but regardless it had fallen in the final.

Dutch Series 2
Crushtacean entered the second series of the Dutch Wars as Krab-Bot, where its first battle was against Alien Destructor 2. Krab-Bot grabbed Alien Destructor, and tried to push it around, but it escaped and shoved Krab-Bot into Dead Metal's CPZ. Krab-Bot escaped unharmed and grabbed Alien Destructor again. Dead Metal intervened to separate the two, and began cutting into Alien Destructor, puncturing two of its tyres. Time ran out, and the judges ruled that Krab-Bot was the winner.

In the next round, Krab-Bot immediately grabbed and dragged Hammerhead 2 around the arena. Hammerhead 2 got free and tried to flip Krab-Bot over, but couldn't manage to. It rammed Krab-Bot, and Krab-Bot began limping. Krab-Bot attempted to get hold of Hammerhead again, and eventually succeeded and pushed it into an angle grinder, where it was held until time was called. Once again, the judges had to make the decision, and once again they ruled in favour of Krab-Bot.

In the Heat Final, Krab-Bot met Twisted Metal Evo, and began the battle in its usual style, grabbing Twisted Metal and pushing it around the arena. Twisted Metal tried to come back on the attack, but couldn't get its disc spinning. It drove into Matilda's CPZ, and the house robot's flywheel put a huge gash in its armour. Krab-Bot pushed Twisted Metal into Sir Killalot's CPZ, so Killalot picked up Twisted Metal and began spinning it round and round. Krab-Bot opened up the pit, but could not push Twisted Metal down into it before time ran out. The jury ruled that Krab-Bot was the heat winner.

In the Grand Final, Krab-Bot came up against Philipper 2. Krab-Bot tried to grab Philipper, but couldn't due to Philipper's odd shape. Philipper flipped Krab-Bot onto an angle grinder, and the Refbot helped it down. Krab-Bot then managed to grab Philipper by its open flipper, and pushed it into a CPZ, where Shunt and Growler forcefully separated the two. Philipper flipped Krab-Bot again, and before it could close up its flipper, Krab-Bot got its claw stuck inside. Growler separated the two again, and Krab-Bot attacked Philipper from the rear. Both robots tried to dig into one another with their crushing weapons as the timer ran out. The judges ruled in favour of Philipper 2, and Krab-Bot finished just outside of the top four.

Series 7
In Round 1 of the Seventh Wars, Crushtacean went up against UFO, Tartarus and the 10th seeds Behemoth, this then being a rematch for the Series 5 shock. Crushtacean attacked UFO at the start of the battle, but couldn't grab hold of UFO's wedge shape. UFO then got underneath Crushtacean, but as its flipper didn't work, UFO just pushed Crushtacean around. Then Behemoth rammed and tried to lift Crushtacean, but then quickly flipped Crushtacean into an arena wall. Crushtacean was briefly impeded by UFO, but was then flipped very close to the wall again. However Crushtacean escaped, but Behemoth and UFO had ganged up on Crushtacean, ramming and flipping it around the arena, until it drove over UFO and became stuck on the arena wall. Finally left immobile, Behemoth flipped it out as an act of vengeance for the Series 5 defeat at Crushtacean's claws. Crushtacean returned for The Third World Championship. In its qualifier it faced Irish robot Topbot. Crushtacean quickly grabbed hold of Topbot and pushed it into the CPZ, but it escaped. Topbot attacked Crushtacean with its spinning disc but it did no damage. Topbot then drove into the arena wall and Crushtacean grabbed hold of it again and pushed it around the arena. Crushtacean then nudged the pit release button and dropped Topbot into the pit of oblivion.

In the first round, it faced Dutch Champions PulverizeR and Swiss robot Snake Bite. Crushtacean immediately opened the pit, but was attacked by PulverizeR. Meanwhile, Snake Bite looked like it had broken down. Crushtacean then rammed PulverizeR against the arena wall, but couldn't get a grip on PulverizeR's slanted body. Snake Bite had been counted out, but had also come back to life and started attacking both of its opponents and tried to crush into Crushtacean. The match ended and the Judges decided that Crushtacean had qualified for the Semi-Finals.

Here it met Supernova, which was representing Sri Lanka. Crushtacean quickly rammed Supernova, but it looked like some pieces came off Crushtacean after colliding front on with Supernova's disc. Crushtacean then appeared to be losing mobility and was left stranded near Shunt's CPZ. Supernova attacked it a few more times and Crushtacean completely stopped. Crushtacean was then counted out and picked up by Sir Killalot, who paraded Crushtacean around the arena, eventually dropping it on the floor flipper. Crushtacean was flipped and then due to its rounded shaped rolled into the arena wall and almost out of the arena. One of Crushtacean's claws had broken and cease was called, eliminating Crushtacean from the tournament.

Series 9
Crushtacean competed in Heat 4, where it faced newcomers Apex, Series 8 competitors, Ironside3, and Grand Finalist from the previous war, Pulsar. "Only here on Robot Wars will you see a fight between three huge spinners and a crab."

- Dara Ó Briain

Crushtacean's initial movements were tentative as it crept around in the centre of the arena. Suddenly, Crushtacean turned its rear towards Ironside3 which was fast approaching, and a subsequent hit took a chunk out of Crushtacean and sent it spiralling over the Flame Pit. Crushtacean showed no signs of movement as the arena hazard lit up with fire, and with Apex also immobilised from an explosive attack from Pulsar, the two were counted out. Cease was called, and Crushtacean's Series 9 campaign came to an immediate end.

Robot Wars Live Events
After a 12-year absence from the robot combat scene, Crushtacean came out of retirement in 2016 to fight at the first Robot Wars live event of the year in Manchester. In the first show, Crushtacean showed that it was still a very capable battler, grabbing Kill-E-Crank-E, which would eventually break down, outlasting Chimera which pitted itself, and defeated Meggamouse to win its melee. Crushtacean also took part in a Tag Team battle, siding with Iron-Awe 7. Iron-Awe quickly immobilised Ceros but broke down in the process, leaving Crushtacean to fight Cherub alone. Crushtacean dominated the battle, refusing to let go of Cherub, before eventually breaking down, leaving Cherub as the winner on a judge's decision. It managed to reach the semi-finals of the main competition before being flipped out the arena by Ripper. Crushtacean managed to finish 3rd in this event.
