Robot Wars Wiki

"M.R. Speed Squared is a ring spinner - 360° offence, 360° defence. If you touch it, you'll be ripped to pieces!"
— Peter Forsey

M.R. Speed Squared (pronounced "Mister Speed Squared") was a heavyweight robot built by Team Forsey, and their entry for Series 8-9 of Robot Wars. It reached the Head-to-Head stage in each series after convincingly winning its Group Battles, but was eliminated on both occasions after failing to score enough points to progress to the Heat Final, despite collecting a head-to-head victory over Foxic in Series 8.


"M.R. Speed Squared has an enormous full-body kinetic energy disc. They have interchangeable weapons which they can attach to the disc depending on their opponents’ weakness. These include heavy weights and spikes. The 22kg steel disc spins at a force of 80 kilojoules – which the team say is powerful enough to slice through a car. M.R Speed Squared’s weapon fully protects the body and wheels of the robot, but could be susceptible to attacks from an axe. This is the only robot in the competition with a 360 degree full body spinner."

As the successor to the team's previous entry Revenge of Trouble & Strife, M.R. Speed Squared was a circular robot armed with a rim spinner. The team decided to forego the flipper of Revenge of Trouble & Strife to allow the robot to be invertible. The robot's full-body spinning steel rim was angled, and in Series 8, the 22kg rim was capable of storing 80 kilojoules of kinetic energy with each rotation, and during the build process was capable of spinning at 1000rpm. This allowed M.R. Speed Squared to inflict high amounts of damage upon hitting opponents, with Team Forsey claiming that it was powerful enough to 'slice through a car' according to the Robot Wars website. The rim was interchangeable, so the team could pick the most appropriate blade depending on its opponents. Its armour consisted of rubber-mounted 3mm aluminium over a 3mm steel frame. However, the team were forced to remove part of this armour as it pushed the robot over the weight limit, leaving one side vulnerable to overhead attacks, and the robot was slow at 8mph. M.R. Speed Squared's bearings were also unstable, which meant that the robot would often lose the use of its weapon once the bearings were broken.

"If M.R. Speed Squared works as it should, nobody will want to fight us."
— Peter Forsey

M.R. Speed Squared as it appears in Series 9

A brand-new M.R. Speed Squared returned in Series 9, sporting a much lower profile. Although its spinning rim now spun at 900rpm, it now weighed 35kg, and the robot's speed was more than doubled, to 17mph. The rim was made from 10mm HARDOX with two 10cm tool steel teeth. This version also addressed the issue with the robot's bearings, and swapped the metal bearings for rubber tyres, in an attempt to improve the reliability of the weapon. However, this was not entirely successful, with the rim ceasing to work in various battles, and the robot also suffered from stability issues when the rim was spinning. The top of M.R. Speed Squared was now even more exposed to overhead weapons, with little protection in place.


The name M.R. Speed Squared is derived from the equation that calculates the kinetic energy of the spinning rim, the M.R. representing mass and radius. Although "M.R." stood for mass and radius, the robot's name was pronounced as "Mister Speed Squared" by its team. In Series 8, the presenters and Jonathan Pearce also used this pronunciation, but began to pronounce the first two letters of the robot's name individually in Series 9, despite Peter Forsey not doing the same.

Erroneously, the robot's name was spelled simply as "MR SPEED SQUARED" or "M.R SPEED SQUARED" on television. The correct name is "M.R. Speed Squared", featuring two full stops.

M.R. Speed Squared with Team Forsey in Series 8

M.R. Speed Squared was entered into Robot Wars by the Worcestershire-based Team Forsey, who had previously entered the original run of the show with Trouble 'n' Strife and Revenge of Trouble & Strife. Team Forsey was captained by the 52-year old father of the team, Peter Forsey, a cardiologist by trade and the lead builder of M.R. Speed Squared, who drove the machine in battle.

"This family team is made up of Peter and his two sons. They have no professional engineering qualifications, but they have many years of experience and skills between them in different forms. In the past Jake has built go karts, small robots and has experience in computer programming. Sam is currently studying a motorsport engineering degree, whilst Peter used to work for a company designing and building computer interface. He also motorised his tricycle when he was only ten. Together they share a passion for old school engineering, and Robot Wars, so much so, Peter has promised to marry his long-term girlfriend, Ellie, if he does not win this series. "

Team Forsey enter the arena in Series 8

Peter Forsey was joined on the team by his two sons, who were young children during the original run of the show, but were now old enough to assist with the maintenance of the machine. 24-year old Jake Forsey was a GIS analyst in the IT trade, and was listed as the "Chief Strategist and Tactician" on the Robot Wars website. 22-year old Motorsport Engineering student Sam Forsey was the team's welder during construction, although he could not reprise this role at Robot Wars due to all welding for every competitor being completed by a designated welder on-site. The Robot Wars website also referred to Sam Forsey as "the muscle and graft" of the team.


M.R. Speed Squared's application video for Series 8

When Series 8 of Robot Wars was first announced, Team Forsey created an application video to use in qualifying for the series, and M.R. Speed Squared was selected to compete. M.R. Speed Squared also qualified for Series 9 in similar fashion, having created a second application video to detail the new version of the robot. The team designed a third version of M.R. Speed Squared, with which they intended to enter Series 10[1], but the robot was not selected to compete on this occasion.

Robot History[]

Series 8[]

"At work, we try to avoid fatalities, but at Robot Wars, that's the mission!"
— Peter Forsey, cardiologist and team captain, during the team's VT

M.R. Speed Squared appeared in Heat 2, and faced newcomers Chimera, Foxic and Wild Card Warriors competitor Draven. Due to the robot being overweight, Team Forsey had to remove the armour on the bottom of M.R. Speed Squared, leaving its internals exposed. This left the exposed internals were visible to all, as M.R. Speed Squared entered the arena inverted.

Angela Scanlon: "What's the ideal opponent for you?"
Peter Forsey: "Something made of a composite material like kevlar, something like that machine over there in our heat actually!"
— Early intentions to target Draven

Ripping a tyre from Chimera

M.R. Speed Squared rips armour from Draven

M.R. Speed Squared spent the first few seconds getting their spinning rim up to full speed, and once they had, it immediately targeted Chimera, and punctured one of its tyres, tearing it loose, the second hit removing the tyre completely. With Foxic and Draven remaining, M.R. Speed Squared chose to target Draven next, sending it spinning away with a blow, ripping Kevlar from its body. Although Draven was attacking the nearly lifeless Foxic, M.R. Speed Squared landed another blow on Draven, immobilising it. M.R. Speed Squared had qualified for the head-to-head round with Foxic, although it was later realised that the robot had lost some weapon bearing motors in the process.

M.R. Speed Squared's first opponent in the head-to-heads was Thor.

M.R. Speed Squared drives into the pit

Proving this to be a regular tactic, M.R. Speed Squared avoided Thor in the opening moments to get its spinner up to speed, although it was slammed into the pit release button, halting its progress. The team's efforts to run away saw M.R. Speed Squared slammed into the arena wall, over the flame pit, and into Dead Metal's claws, where Thor punched a dent into the aluminium armour, and slammed it into a wall again. M.R. Speed Squared seemed to have lost the ability to spin its weapon, and an axe blow from Thor put a huge gash in M.R. Speed Squared. The spinning rim eventually started working again, but Thor's anti-spinner wedge protected itself. Both robots drove over the floor flipper, which threw both robots, leaving M.R. Speed Squared's unarmoured underbelly exposed. Although M.R. Speed Squared's spinner protected it at first, a strong blow disabled it for the rest of the match. The spinning rim was hammered by Thor, before the exposed internals were punished by Thor. Either by accident, or to protect the robot's internals, M.R. Speed Squared drove straight into the pit, awarding themselves a loss.

In its next head-to-head, M.R. Speed Squared fought Foxic again, in a battle considered to be one of the least entertaining in the show's history.

"That is one of the worst fights - it might even be the worst fight I've seen in the whole of Robot Wars. It was just complete rubbish."
Noel Sharkey on the quality of M.R. Speed Squared and Foxic's head-to-head

M.R. Speed Squared activates the pit

The only danger M.R. Speed Squared suffered

M.R. Speed Squared implemented its usual tactic of running away to get the rim up to speed - although in this match, the rim had broken, so M.R. Speed Squared spent the entire match fleeing from Foxic, which was in turn focused on attacking the House Robots. Finding something to do, M.R. Speed Squared pressed the pit release button, before continuing to keep its distance. M.R. Speed Squared launched a gentle final attack of driving into Foxic, but was lifted in return, and cease was called on an uneventful match. The Judges ruled, on a 2-1 split decision, that the less haphazardly driven M.R. Speed Squared had won the match, awarding them two points.

"Bit of an anti-climax really, we'd spent a lot of time fixing the disc, hoping to get a big bang on Foxic. Unfortunately in the arena it didn't spin up, we don't know why, everything else was fine, we got the Judges' decision, but it didn't feel very glorious, really."
— Peter Forsey

On two points, M.R. Speed Squared had the opportunity to qualify for the Heat Final, if it could defeat newcomer Shockwave.

M.R. Speed Squared is lifted onto the wall

Rather than flee, M.R. Speed Squared drove in circles to maximise the speed of its rim, although Shockwave was mostly unharmed, and pushed M.R. Speed Squared into Sir Killalot and Dead Metal, which cut through the chassis. When M.R. Speed Squared attacked Shockwave, it buckled its opponents scoop and knocked a drive chain loose, but then M.R. Speed Squared was lifted against the arena wall by Shockwave, where it started to smoke, and was pushed towards Sir Killalot again.

"Team captain Peter works in a hospital theatre as a cardiologist, plenty of heart in M.R. Speed Squared, but it's about to be arrested, it would seem, by Shockwave!"
Jonathan Pearce

M.R. Speed Squared is eventually pitted

M.R. Speed Squared was not being given chances to spin up its rim, and was overturned by Shockwave, once again exposing its vulnerable internals. Rammed into the wall, M.R. Speed Squared was held above the arena floor, and then driven right onto the lip of the pit. Although both robots had nearly fallen into the pit, it was Shockwave that achieved the finishing blow, and M.R. Speed Squared was pushed into the pit, eliminating it from the competition.

"M.R. Speed Squared into the square-shaped trap!"
— Jonathan Pearce

Series 9[]

M.R. Speed Squared competed in Heat 3, once again facing its infamous opponent Foxic, alongside newcomers Expulsion, and the new robot from Team 13, Heavy Metal. Peter Forsey entered the competition with a wager, stating that if he didn't win Robot Wars, he would propose to his long-term girlfriend Ellie, who was in the audience. Dara Ó Briain noted that Ellie would be cheering against M.R. Speed Squared.

Dara Ó Briain: "What happens if you DO win Robot Wars? Why would you not celebrate?"
Peter Forsey: "I'm off the hook! That's why I've been working so hard on it!"
— Peter Forsey's unique agenda for winning Robot Wars

M.R. Speed Squared attacks Foxic's wheels

After being given the chance to reach its spinner's top speed, M.R. Speed Squared hit Expulsion, which was inactive before the battle had started. Foxic knocked M.R. Speed Squared away, but after another period of avoiding the action, it slammed into Foxic's side, knocking the spinning robot off-balance due to its gyroscopic forces.

"M.R. Speed Squared looks wobbly here, I wonder if it's so powerful, it's uncontrollable!"
— Jonathan Pearce

Expulsion suffers more damage from M.R. Speed Squared

M.R. Speed Squared is flipped by the floor spikes

At this point, however, Foxic was turned over by the floor flipper, and Expulsion was long defeated, with even Heavy Metal suffering drive problems, so M.R. Speed Squared comfortably qualified. It ripped through the thin armour of Expulsion, and buffeted Heavy Metal, but rebounded onto the arena spikes, which thrusted into the air, causing late worries for the victorious M.R. Speed Squared.

"M.R. Speed Squared rotating looks improved, until then? Have they sustained damage by that?"
— Jonathan Pearce as M.R. Speed Squared is damaged by the spikes

Team Forsey repaired the minor damage they sustained, and fought Heavy Metal in its first head-to-head.

M.R. Speed Squared is tossed by the floor flipper

M.R. Speed Squared started spinning its rim, but was immediately charged by Heavy Metal, blasting it into the wall and cancelling the momentum of the spinner. M.R. Speed Squared's weapon was broken by this first hit, and was pushed over the pit and into the arena wall. Unable to escape the pursuant Heavy Metal, M.R. Speed Squared was pinned into another corner of the arena, and then pushed into the Arena Tyre, opening the pit.

"Peter, you are heading down the aisle! If it continues like this, mind you, Ellie might not want you!"
— Jonathan Pearce

Shunt axes the armour of M.R. Speed Squared

M.R. Speed Squared and Heavy Metal fall into the pit

After briefly slipping under Heavy Metal's wedge, M.R. Speed Squared continued to be dominated, and was thrown over by the floor flipper, then pushed into Shunt, where its thin top armour was punctured. M.R. Speed Squared resorted to evasion, almost driving into the pit. It stayed near the pit, attempting to lure Heavy Metal closer, but M.R. Speed Squared was simply pitted by its opponent, even though Heavy Metal fell in afterwards. As M.R. Speed Squared was the first to enter the pit, it lost the battle by KO.

"Shunt got its axe in here, which has bent our sprocket down onto the motor, so it's not solid."
— Peter Forsey

M.R. Speed Squared was damaged in the last battle, but after its sprocket was straightened, it was ready to battle Thor, in a rematch from Series 8.

M.R. Speed Squared is axed by Thor

M.R. Speed Squared receives more punishment

Unfortunately for Team Forsey, their weapon did not spin, and Thor charged M.R. Speed Squared into the arena wall, landing two axe blows. M.R. Speed Squared became stuck on Thor's wedge, but was released by an axe blow, where it became clear that the killer blow had been inflicted. M.R. Speed Squared received more attacks from Thor's axe, and was gripped by Sir Killalot before 'cease' was called. With a second battle lost by knockout, M.R. Speed Squared was left unable to qualify for the Heat Final.

"Our batteries packed in, basically."
— Peter Forsey explains the true cause of M.R. Speed Squared's immobility

As M.R. Speed Squared entered the last battle without a working spinner, the team took their robot to the testing arena ahead of their final head-to-head with Concussion, and discovered that they still could not operate their weapon. After spending the remainder of their repair time making a last effort to fix their robot, a deflated Team Forsey entered the arena for their last battle.

"M.R. Speed Squared's groundbreaking design is proving tough to fix. Things are going from bad to worse for the family team"
— Dara Ó Briain

M.R. Speed Squared flips wildly in the air

M.R. Speed Squared is burned in the grips of Dead Metal

Surprisingly, the team had managed to fix their weapon after all, and M.R. Speed Squared span in circles to increase their acceleration. However, this brought their robot off the arena floor, and Concussion smashed into M.R. Speed Squared, causing it to flip and turn over wildly in recoil, once again disabling the spinner. After taking a hit to their bottom armour from Concussion, M.R. Speed Squared relied on their back-up plan of opening the pit, but it was almost manoeuvred into the pit by Concussion. The drum spinner then wedged under M.R. Speed Squared and pushed it into Dead Metal, although the House Robot struggled to reach the low profile of the body spinner. M.R. Speed Squared was slow in its escape, and drove worryingly near to the pit, but then attempted to push its opponent, only sustaining light attacks in return.

"I don't think they can get much damage caused on M.R. Speed Squared because of that blade acting as [armour], it's stopping the drum of Concussion really causing too many problems!"
— Jonathan Pearce, as Concussion fails to reach the body of M.R. Speed Squared

M.R. Speed Squared was pushed back into Dead Metal and was held over the flame pit, and only retreated into the claw of Sir Killalot. M.R. Speed Squared was held up high, and tossed into the centre of the arena by the House Robot. Concussion then attempted to push M.R. Speed Squared into the pit once more, but while the two robots pushed one another, Concussion caught fire internally. M.R. Speed Squared used the remaining seconds of the battle to ram Concussion, which could only move on one side, but still made contact with its opponent's drum. Cease was called before M.R. Speed Squared could truly make a comeback, and the battle was sent to a Judges' decision.

"We did think briefly that it may be curtains, straight away after that glorious little spin, but you pulled it back!"
— Angela Scanlon

Team Forsey had enjoyed their final battle of the series, but despite Concussion's internal fire and loss of mobility, the Judges unanimously declared that M.R. Speed Squared had not performed strongly enough throughout the battle, and Concussion was declared the winner. Regardless, Peter Forsey pledged to propose to his fiancée, creating a happy ending for the team.
