* Robot Wars Series 9

## Overview

"*Double the trouble, double the pain!*"
— *Robot Wars: The Official Handbook*
**Crackers 'n' Smash**, alternatively **Crackers n' Smash** or abbreviated to **CnS**, was a two-part clusterbot which entered Series 9 and 10 of *Robot Wars*, having also qualified for Series 8 before withdrawing.

In its series debut, it reached the Head-to-Head round and achieved a win over Coyote, but was eliminated there in third place after suffering losses to the reigning and future champions Apollo and Carbide. In Series 10, Crackers 'n' Smash was drawn against heavily-established opponents in all of its battles. Though managing to outlast Aftershock in its initial Group Battle, it would ultimately be eliminated again after collecting losses against Eruption and Big Nipper respectively.

## Design

"*A clusterbot is a machine that's made of two or more parts, which gives our opponent not just one problem to deal with, but multiple issues about how you fight something that's in two places at once.*"
— Alex Botwright explains the reasoning behind Crackers 'n' Smash
Crackers 'n' Smash consisted of a pair of four-wheel drive box-shaped robots with front wedges and two different weapons. Both were built over the course of three months, at a total cost of £8,000. Due to rule changes implemented for Series 9-10, each half of Crackers 'n' Smash could still fight individually if the other was immobilised during battles. As a result, both halves have to be immobilised in order for the whole robot to be eliminated.

"*This cluster bot is made up of 60kg 'Smash' and 50kg 'Crackers'. While the concept of using cluster bots makes the team vulnerable to flippers, Crackers benefits from a compact lifting weapon and Smash has a high mass spinner.*"
— Robot Wars: Build Your Own Robot on Crackers 'n' Smash in Series 9
**Crackers** (Kawasaki green) weighed 50kg and originally featured a compact front-hinged 10kW lifting arm in Series 9. For Series 10, the lifting mechanism was altered into a rear-hinged one, with interchangeable forked or scoop-type lifters. The forked lifter was used in Crackers 'n' Smash's opening melee, while the scoop lifter was used in the Redemption Round.

"*This insectoid like set of prongs is designed to go either side of a flippers front wedge and slide under them before they get under us.*"
— Team Conker explain the purpose of Crackers' forked lifter
Crackers was armoured in 5mm HARDOX, and the lifter was powered by two 3.7Kw motors. It originally had a HARDOX base in Series 9, but this was swapped for aluminium in Series 10 to save weight, where it also gained a steeper wedge made of 10mm ARMOX. In the event of the new shell being damaged beyond repair during Series 10, Crackers could have been equipped with its original bodyshell from Series 9. Additionally, the team incorporated an entanglement device onto Crackers, suspending loose chains above Crackers when battling vertical spinners.

"*For Series 10 Crackers 'n' Smash added an entanglement weapon consisting of single 1m lengths of steel cable connected in two places on a glass fibre rod*"
— Robot Wars: Build Your Own Robot on Crackers' entanglement device
**Smash** (pearlescent purple) weighed 60kg, and featured a custom-designed 13kg drum-like spinner with four interconnected steel discs, spinning at 8000rpm in Series 9, and a record high of 11,000rpm in Series 10, providing a tip speed of 250mph. Its armour consisted of 3.6mm hardened steel with a 5mm stainless steel front wedge, and this armour was improved for Series 10. The robot was four-wheel driven, with all four wheels being exposed on top, despite those at the front being unable to reach the floor when the robot is inverted. The front two wheels were more protected in Series 10 by Smash's steeper wedge.

"*Using custom VESC's designed by Rory Mangles of Team Nuts to control Scorpion HK 5020 brushless outrunners, both Crackers and Smash pack 7.5kw of drive into just half the weight of a normal HW!*"
— Team Conker Facebook page
Both Crackers and Smash used custom VESC brushless speed controllers co-developed with Rory Mangles of Team Nuts. These are high-amperage versions of the VESC controllers designed by Benjamin Vedder, modified for use in robot combat. Modifications over Vedder's original design include changes to the current shunts, wider higher power tracks and improved mounting points for higher amperage and improved current handling over the standard VESCs.

"*Given that CnS was effectively a Season 1 robot, when we managed to make it into Season 2, we were a Season behind everyone else in terms of experience and knowledge; nothing teaches you more about your robot than when it breaks! When we were accepted for Season 3, we knew we couldn't stand still. Despite being in running condition and, given new armour & weapon bulkheads for smash, we could have gone in again with very few changes... but that would put us two seasons behind everyone else in terms of design.*"
— Team Conker
For Series 10, Crackers 'n' Smash underwent several modifications which reduced its combined weight by 16kg; Team Conker removed excess material from each robot's bulkheads, as well as trimming the gears and pulleys in their drive systems. The team also brought more spare components and installed secondary removable links into both robots; the latter to comply with new rules concerning duplicate links for invertible robots.

"*Built to be different, innovative and exciting, Crackers ‘N’ Smash have fought some of the best robots ever to compete, including all three Robot Wars champions!*"

## Robot History

### UK Robot Wars Series 8

Before its televised debut, Crackers 'N' Smash initially qualified for Series 8. However, the robot was not completed in time for its first battle, and would not be finished for a further twelve hours. As such, Crackers 'N' Smash withdrew, but footage from the team's VT was still used in the opening sequence of the show, where the team's featherweight Conker 3 destroyed a monitor. David Weston also remained on-set to assist with the repairs of Chompalot.

### UK Robot Wars Series 9

"*Entering Robot Wars was a childhood dream... and now I'm about to become your worst nightmare.*"
— Alex Botwright
Crackers 'n' Smash made its combat debut in Heat E of Series 9, where it faced Series 8 runner-up Carbide alongside fellow newcomers Meggamouse-successor to Mighty Mouse, and Trolley Rage in its Group Battle. Originally, it was intended to face Apollo, Coyote and Ms Nightshade, but the withdrawal of Point Blank caused Crackers 'n' Smash to be moved into its new group battle.

"*...and fascinating to see how the clusterbot Crackers 'n' Smash do here...*"
— Jonathan Pearce during Crackers 'n' Smash's first battle
At the start, Crackers immediately drove across the arena, where a bump from Meggamouse sent it careering onto the Flame Pit. Crackers remained stuck there as Smash darted over the closed pit and was hit from the front by Carbide's bar spinner. The impact warped Smash's front wedge, leaving it trailing as Smash reversed into Carbide again and pushed Meggamouse onto the arena spikes. Meanwhile, Crackers raised its lifter as Trolley Rage pushed it off the Flame Pit, and dodged Carbide as it hit Smash a few more times. Smash sped over the Flame Pit as it drove out of the empty CPZ, its wedge finally breaking off as it caught the edge of the hazard. Crackers sat in the middle of the arena close to the immobilised Trolley Rage and Meggamouse's minibot, Charles, where it and Meggamouse attempted to push Trolley Rage back.

"*Ahh, running away! Running away! Ahh!*"
— David Weston as Smash dodges Carbide
Smash continued driving around the arena and dodging Carbide in the background, before Crackers was attacked by Carbide. Sustained blows from Carbide caused sparks to fly and Crackers' lifter to be ripped off, but Crackers survived, and attempted to push Meggamouse while the pit descended. Smash withstood a few more blows from Carbide's spinner before being spun away, but escaped as Crackers lingered over the Floor Flipper and drove into Meggamouse again. At the same time, Carbide destroyed Meggamouse's wheel, before Smash was again chased by Carbide across the arena and pushed Charles into the pit just as 'cease' was called. As a result, Crackers 'n' Smash progressed to the Head-to-Head round along with Carbide, despite both robots requiring extensive repairs to their weapons; in addition to the warped wedge, Smash had also sustained several gashes to its weapon mount.

**David Weston**: "*This is fixable.*"
**Alex Botwright**: "*This is fixable.*"
**David Weston**: "*Right, let's get cracking!*"
— Team Conker assess the damage inflicted to Crackers 'n' Smash
In its first Head-to-Head, Crackers 'n' Smash faced fellow newcomer Coyote.

Smash immediately darted towards Coyote as Crackers turned towards the Flame Pit, but was grabbed by Coyote and pushed into the wall. Coyote dragged, spun and pushed Smash into Dead Metal, whose saw grazed Smash's weapon mount as Crackers attempted to free its other half. Both parts escaped as Dead Metal let go of Smash, before Smash slammed into Coyote and in turn pushed it into Dead Metal. However, it briefly got caught by the House Robot in doing so, but Crackers and Smash soon retreated to the middle of the arena, and gathered around Coyote after it pressed the Arena Tyre and activated 'Rogue House Robot' mode. Dead Metal charged into Smash once again, and pushed it onto the Flame Pit despite Crackers' attempt to push him away.

"*Very low machines, you can see the way they're slipping away at times, but [Dead Metal's] got [Smash] here now.*"
— Jonathan Pearce observes Crackers 'n' Smash's low height as Dead Metal grabs Smash again
Smash quickly drove away as Dead Metal released his grip, before accidentally driving over Crackers as the latter rammed into and under Coyote. Both Crackers and Coyote became stuck together as a result, so Smash pressed the Arena Tyre, and in spite of 'Rogue House Robot' having already once been enabled, Matilda came out of her CPZ to hit Coyote twice. The attack briefly rendered Coyote immobile on one side, but Crackers 'n' Smash persevered, with both halves ramming, bumping and pushing Coyote around. Smash eventually reversed Coyote into an empty CPZ, where it was left immobile, but drove itself onto the Flame Pit again seconds later, and remained stuck there as the countdown timer began. Since Crackers was still moving around the arena, half of Crackers 'n' Smash was still mobile, securing the clusterbot victory and three points as a result.

**Ian Botwright**: "*Hitting the tyre, not getting the pit – twice - getting a House Robot, get the House Robot coming out at you. It's... I'm sorry...*"
**Alex Botwright**: "*It's terrifying.*"
— Team Conker's verdict on 'Rogue House Robot'
This enabled Crackers 'n' Smash to share joint-first on the leaderboard with its next opponent, Carbide. Before the battle, Team Conker removed both Crackers and Smash's weapons to prevent them being damaged by Carbide's spinner, as well as to make them low enough to prevent the latter from causing significant damage elsewhere.

"*We're going in without the weapons. We know they're going to get torn off, so it's a pure three-minute survival match.*"
— David Weston explains Team Conker's decision to remove Crackers 'n' Smash's weapons
However, this action contravened the active weapons rule. The *Robot Wars* production crew were not aware of Crackers 'n' Smash's revised state until both robots had been loaded into the arena, at which point Team Conker faced the possibility of being potentially disqualified from the battle. Nevertheless, when asked by the production crew about this, Team Carbide were content with fighting a weaponless Crackers 'n' Smash, requesting that the battle should go ahead anyway.

As the battle began, Smash immediately drove into Carbide, with both robots sustaining hits from Carbide's spinner as they attempted to surround it. In doing so, Crackers momentarily got underneath Carbide, but Carbide repeatedly hit Smash's replacement wedge, sending sparks and shrapnel flying as Smash turned Carbide around and drove itself onto the Floor Flipper. Smash was flipped over as a result, and used its inverted wedge to push Carbide off Crackers. Both halves survived more blows from Carbide's spinner as David Weston reported control problems, with Smash hitting the Arena Tyre and activating the pit as he did so. Crackers ‘n’ Smash withstood several more attacks from Carbide, before Smash was sent spinning violently into the wall by Carbide. Upon impact, Smash broke off a wall panel and flew up against the bulletproof panels, landing on Shunt's scoop just before Carbide hit Crackers again. Immediately, 'cease' was called, and the battle was stopped for safety reasons while repairs to the arena were carried out.

"*Stay out of trouble, Crackers 'n' Smash; you didn't manage it. And again – whoa! Wow, away goes Smash!*"
— Jonathan Pearce summarises Crackers 'n' Smash's performance as replays of Carbide's battle-stopping attack are shown
While the repairs were completed, Team Conker declared that they would formally forfeit the battle to Carbide, in an effort to make sure that both halves of Crackers 'n' Smash did not sustain too much damage ahead of their next battle. In spite of Carbide's attacks on their bodyshells, however, both Crackers and Smash's chassis and drivetrains had remained intact throughout.

"*One brick of a robot! The drive system’s fine. Mechanically, the entire robot’s fine, which also means... we can fight Apollo, and we can fight Apollo properly.*"
— Alex Botwright assesses the integrity of Crackers 'n' Smash's chassis and internals
This was crucial in enabling Crackers 'n' Smash to be ready in time to fight defending champion Apollo in its third – and last – Head-to-Head. For this battle, Team Conker finally succeeded in getting both halves' weapons working since the Group Battles, and were cautiously optimistic about their chances of reaching the Heat Final.

"*So we're either in for the high jump or we could potentially bring about the biggest upset by knocking out the current champions.*"
— David Weston before the Head-to-Head against Apollo
This time, Crackers approached Apollo first, dodging Apollo's initial charge and momentarily getting underneath it. It pushed Apollo around the arena as the latter fired its flipper to free itself, before Smash drove up Apollo's wedge and was pushed back close to the wall. In response, Smash was pushed by Apollo towards Dead Metal, with Apollo reversing over Crackers while Smash pressed the Arena Tyre. The pit descended, with Crackers again attempting to push Apollo while Smash darted behind and was caught by Dead Metal. Crackers was eventually thrown into Dead Metal's saw by Apollo, and it was left unable to self-right as Dead Metal charged into it, sending more sparks flying as his saw made contact with Crackers' underside.

"*And Crackers, I think, is over and out.*"
— Jonathan Pearce after Crackers is flipped by Apollo
Apollo proceeded to throw Smash around the arena several times, with Smash struggling to drive away on its back as Dead Metal grabbed and pushed it again. Crackers was briefly nudged by Apollo as it backed into the Arena Tyre and activated 'Rogue House Robot' mode, while Dead Metal sliced into the inverted Smash's side, sending sparks flying everywhere as he did so. However, Smash escaped, and survived to a Judges' decision as Apollo pushed and threw it against the wall twice more. The Judges declared Apollo as the winner, leaving Crackers 'n' Smash with no points as a result. This ensured that Crackers 'n' Smash finished third on the Head-to-Head leaderboard with three points, which was not enough to prevent it from being eliminated from Series 9.

**Ian Botwright**: "*Had a great fight there. Fantastic fun.*"
**Alex Botwright**: "*That was... surviving three minutes with Apollo was... frankly surprising. I'm quite glad in some ways 'cause I don’t have to fight Carbide again.*"
— Ian and Alex Botwright of Team Conker on Crackers 'n' Smash's last battle of Series 9
### UK Robot Wars Series 10

"*Double the robots, double the destruction!*"
— Ian Botwright
Crackers 'n' Smash returned in Heat B of Series 10, where their first battle proved to be a daunting draw against the reigning runner-up Eruption, and fourth-place finisher from the previous series, Aftershock. In preparation for their encounter with the latter's vertical spinner, an entanglement device was suspended above Crackers in the form of hanging chains.

At the start of the battle, the two clusterbots separated, with Smash reversing while Crackers assaulted Aftershock, hoping to employ its entanglement device. However, Aftershock easily ripped the chains from Crackers, at little consequence to itself, and pushed Crackers into an empty CPZ, grinding at its side armour. Fleeing from Eruption, Smash bumped into its teammate, but found its way underneath Aftershock, holding it in place to test the two spinners against each other in a relatively even contest, until the floor flipper launched Smash into the air, and at this stage Aftershock damaged the underside of the flipper, raising concerns with health and safety.

"*You can't drive, the arena flipper's buggered!*"
— Ian Botwright
Ian Botwright sensed the danger of the broken arena hazard, and encouraged his robots to cease movement so the battle could be halted. Crackers 'n' Smash fled for safe areas of the arena to confirm whether or not the battle would be suspended, but it became apparent that the battle needed to continue, and both robots were hit hard by Aftershock, with the lifter of Crackers being bent out of shape. Crackers 'n' Smash continued to behave passively in the centre of the arena, when Eruption increased the momentum of the match by launching Aftershock out of the arena.

"*Fine then, keep fighting!*"
— Alex Botwright
Smash was still inverted, unable to assert itself while Crackers was thrown into the air twice by Eruption in an empty CPZ. Crackers bravely charged into Eruption, engaging it in the centre of the arena, but was manoeuvred over the flame pit, and eventually to the arena wall, where Eruption threw it out of the arena. Crackers 'n' Smash were not defeated yet, as Smash remained mobile, albeit only for a short period until Eruption drove under the exposed ground clearance of Smash, and blasted it into the trench at full power, causing Smash to hit the plexiglass entrance door.

"*That was a good one, and we're in the trench. Well done!*"
— Alex Botwright to Team Eruption
The battle had ended in loss for Crackers 'n' Smash, and was followed by a small argument in the control booths, with Team Shock blaming Ian Botwright for leading the teams to believe that the battle would be halted for safety reasons, although this was forgiven.

Despite Crackers 'n' Smash being sent into the Robot Redemption Knockouts, the liberty of it remaining active in its Group Battle for longer than Aftershock allowed it to face the robot which had finished third in the heat's other Group Battle, Big Nipper. Crackers was applied with its alternative scoop-shaped lifter and entanglement devices, while Big Nipper had applied its vertical spinner to challenge Crackers 'n' Smash.

"*This to stay in the heat. The team of Crackers 'n' Smash, not fanatics who want to win. For them, Robot Wars is more about the enjoyment of designing and creating something - the charity of human spirit. Bleugh! Pass me the sick bucket...*"
— Jonathan Pearce calls the start of Crackers 'n' Smash's Redemption battle
Crackers 'n' Smash started promisingly, with Smash slamming into Big Nipper while avoiding the spinning disc, and Crackers pushing Big Nipper backwards. However, Smash became stuck on the flame pit, and Big Nipper charged Crackers across the arena, ripping away one of its entanglement devices, again without jamming the opposing spinner. While Crackers was stuck on the surface of the pit, Smash charged head-first into Big Nipper's disc, but was lifted from the floor in recoil, and Smash's mobility was permanently impaired, despite unintentionally freeing its team-mate. The remaining chains atop Crackers were ripped away, and Crackers was buffeted into Sir Killalot by Big Nipper. Unable to drive away, Crackers was helpless as Sir Killalot drove on top of it, trapping the lightweight machine.

**David Weston**: "*He's sat on me!*"
**Jonathan Pearce**: "*You really don't want to be there!*"
— Reactions to Crackers being flattened by Sir Killalot
Smash, which had lost the use of its drum spinner, was buffeted in sequence by the disc of Big Nipper, throwing it against the arena wall, with Smash largely unable to leave its circumference, while Crackers experienced similar issues. In its killer blow, Big Nipper struck the side of Smash, firing it straight into the lighting above the arena, high into the air, and then into the trench below, having broken three arena lights in the process. With Smash out of the arena, Crackers was left to fight alone, but after two blows from the disc of Big Nipper and a period on top of the flame pit, the Judges commenced their countdown clock on Crackers 'n' Smash. Sir Killalot plucked Crackers into the air, and held it aloft until the robot was counted out, putting an end to Team Conker's campaign without any victories in the series.

"*Well it was a good display, but the Botwright family didn't get their bots right in the end, and their clusterbots are mere playthings of Sir Killalot!*"
— Jonathan Pearce
The eliminated Ian Botwright stepped into the trench with Angela Scanlon to inspect their robot and the damaged lights, vowing to return with a new design in a future series, which would ultimately not happen.
