- "How did Sir Chromalot Start? It was one Monday morning and Merrill called an emergency business meeting to discuss Sunday's edition of Robot Wars with Smith. Smith explained to Merrill how every time he watched it he wanted to build one, but had no spare time and the making of a Robot would take many months of hard work. Suddenly both men found themselves sketching and later faxing plans and ideas to each other. By the Thursday Merrill had entered the competition, got a team together, got a boot full of old iron, purchased the radio control equipment and booked a holiday. Smith had been real busy also, drawing up the master blue-print technical drawings for the Robot"
- — The origins of Sir Chromalot from The Hub Nuts website
The Hub Nuts appeared in every series they fought in with Sir Chromalot, which reached the second round in Series 3-6 and competed in various competitions across both series of Extreme. The team originally consisted of Steve Merrill, Steve Smith and David Whitehead. Smith left after Series 3, and Whitehead left after Series 4. Ray Tait, former captain of the recently-retired Centurion team, joined Merrill in Series 5/Extreme 1 and helped completely rebuild Sir Chromalot, replacing its previously ineffective spike weapons with a pneumatic flipping arm.
For the Series 4 Celebrity Special shown as one of the Christmas specials in December 2000, the team were joined by the Boyzone singer Shane Lynch. As per the rules, he had to control the machine for sixty seconds before he was permitted to hand the controls over to the roboteers.
After Extreme 2, Ray Tait left the team. Steve Merrill, along with several engineers from Alchrist Engineering, constructed a brand-new version of Sir Chromalot for entry into Series 7. However, it was torn apart by Scorpion in its qualifier battle, and thus failed to qualify for that series.
The Hub Nuts were considered to be excellent sports and comedians, guaranteed to offer entertainment and laughs throughout their appearances. On many occasions, the team, particularly Merrill, would make jokes out of the competition and fuss over trivial issues such as their outfits.
Sadly, Steve Merrill passed away on June 19th, 2011 from complications relating to bowel cancer.  Both surviving models of Sir Chromalot became the property of Ray Tait.
- Steve Merrill: "You people have got no idea the stress that goes on. Philippa, what jacket shall I wear?"
- Philippa Forrester: "Any interest in who you're fighting?"
- Steve Merrill: "What, the robot? No, the jacket's more important."

The Hub Nuts considered attire very important. As a trademark, members of the Hub Nuts always dressed in tuxedos. One particular exchange in Series 6 showed Steve Merrill more interested in the jacket he would wear than who he was fighting, having brought a whole rack of jackets into the pits. The exchange resulted in Philippa stating that she believed that some of Steve Merrill's jackets were "illegal".
- "...most teams did not like us, but we didn't care...we used the same game plan as boxers use before going into the ring"
- — Steve Merrill
Always interested in making a big show of the competition and entertaining the audience, The Hub Nuts often arrived in style.
- In Series 3, the team arrived in a Rolls Royce, and before their first battle, warmed up the audience by dancing around the arena.
- "...it was a joke, really - 15 minutes before we went on, they said "We need you to do a dance routine," and we're three big guys. We can't dance - it's very obvious that we can't, but we had a go."
- — Steve Merrill, interviewed in the original Robot Wars Magazine
- In Series 4, The Hub Nuts arrived on the back of a truck with a group of cheerleaders, who chanted to announce their arrival. Before Sir Chromalot’s battle with The Steel Avenger, the cheerleaders, known as the Chromettes, also performed a dance routine to a track produced and recorded by Steve and David.
- "The Rolls Royce seemed to go down really well last year. When we got a call saying we'd been seeded into Series 4, we thought we needed to top the Rolls Royce, but what could we do? My sister-in-law runs the dance troupe, which is useful!"
- — Steve Merrill, interviewed in the original Robot Wars Magazine
- In the build-up to their Vengeance battle in Extreme 1, The Class Act arrived in an silver car with a personalised number plate, supported by a group of bouncers, and followed by a squad of majorettes and cheerleaders, who sang a song praising Sir Chromalot. The bouncers also stood by the Judges table during the battle, to “intimidate” the Judges.
- In Series 6, the team arrived in a silver convertible, with a personalised number plate. They filmed a special introduction for the heat, which showed them arriving at the studio in the car, and being greeted by crew members, who helped them select a jacket.
The Hub Nuts also arrived at Extreme 2 in a limousine, but this was not shown on the televised show. 
The team shared a long-standing rivalry with Jonathan Pearce. Pearce originally made a comment about Merrill's weight, which started the dislike between the two. Pearce frequently made jokes about Sir Chromalot, and in turn, Sir Chromalot frequently insulted Pearce, stating at one point that he had a "grease nipple on his chin to keep his mouth moving". Sir Chromalot's weakness was often listed as "Jonathan Pearce" on its statistics boards in later appearances.
The Hub Nuts also had a particular enmity with the International Wreck Crew, with hostilities leading to a Vengeance battle in Extreme 1. Steve and Ray called the opposing team "Plundergirls" repeatedly, and accused them of having no style or skill. The two teams regularly fought grudge matches outside of Robot Wars, and the rivalry was also shown in the Robot Wars Magazine, as one of the Comic Strip fights was between Sir Chromalot and Plunderbird 4. Interestingly, Sir Chromalot won both of these fights under similar circumstances, after Plunderbird drove into the pit.

Outside Robot WarsEdit
Steve Merrill also hosted a live show called “The Robot Zone”. These events were displays of robots including Sir Chromalot, Centurion, Skeletron, Tornado, Chaos 2, Firestorm, Panic Attack, Bigger Brother and the House Robots. Steve Merrill would set competitions for the visitors, offering Robot Wars Merchandise as prizes. All the money raised at Robot Zone events was donated to charity.
