"In Robot Wars Series 2, I entered a team with RoboDoc, this was a company entry sponsored by R Griggs & Co the makers of the famous Dr Martens boots. Unfortunately we were knocked out in the show semi final by King Buxton (a great little robot) and the company lost interest in sponsoring another entry in Series 3."
— Mike Franklin

Robo Doc was Team 101's original machine, which was entered in Series 2 of Robot Wars. It reached the Arena Semi-Final stage in its heat, before being defeated by King Buxton, triggering the famous rivalry between King Buxton and Team 101's machines. Team 101 subsequently entered Series 3-5 with 101, reaching the Semi-Finals there, and Series 6 with the walkerbot Anarchy.


"According to team captain Mike Franklin, the main consideration was that Robo Doc should be something "big and mean", not just another "box on wheels". So it was logical that wheels should be abandoned in favour of tracks (which the team found in a scap yard). The variable gearing in the robot's drive mechanism is set for 13kph (8mph), and its pulling power is over 360 kilograms ... But it is also extremely robust, and can climb over obstacles up to 50 centimetres in height. If it has a weakness, it is that smaller robots can out-manoeuvre it"

The original design of Robo Doc


Robo Doc without its weapon or shell

Robo Doc was a tracked wedge-shaped robot with a lifting arm that could lift 70kg. It was built to resemble a World War I tank, constructed out of aluminium and had spikes on the tracks to enable it to climb over obstacles up to 600 metres in height. It also featured 1hp in pushing power as a result of its strong drive motors, which made Robo Doc the most powerful robot in its Heat despite its light weight. Robo Doc's weapon was initially supposed to be a chainsaw/angle grinder, however this was removed due to weight constrictions and replaced with the lifting arm. However, the arm proved ineffective as it was mounted too high and only had a spike on the end of it. Robo Doc also featured a secondary static blade - a ramming blade beneath the wedge, and cost £1000 to build. It was half a kilo over the then Heavyweight Limit.

"Having persuaded my boss to sponsor the creation of RoboDoc, I had to dream up an exciting design. As there have been so many good designs in the past, something original was going to be hard. ... The tracks are stainless steel and each is powered by a 750 Watt motor. ... So far I have obtained the motors (Bosch) and the controllers supplied by 4QD, who have been very helpful. Batteries have been a problem and in the end have opted for two 25 amp hour Yuasa gel batteries from Maplins. The tracks have now been obtained from the scrapyard and were off an old bottle washing machine! ... The other problem is the best way to gear down the motors. I would have liked to used gearboxes but the cost of manufacture was going to excessive. I opted for a two stage chain drive. The problem with chain is that it takes up a lot or room for a given ratio. We have now got one track unit working and it seems to work quite well. The only problem is that one that the completed side weighs 32Kg so we will need to look at ways to reduce this."

Robot HistoryEdit

Series 2Edit


Sir Killalot picks up Robo Doc

Robo Doc opted for the centre route, dodging Matilda and taking the ramp, bowling over the barrels. Robo Doc then ran head on into Bash, and was attacked by Sir Killalot. It qualified for the Trial with a distance of 10.9m.

"You can hear the engines roaring. I wonder if they can get up and over Bash using those spike-embedded tracks."
— Jonathan Pearce muses as Robo Doc grapples with the House Robots

Matilda gives off sparks as she flips Robo Doc over

In the Trial, Robo Doc faced Matilda in the Joust. Just as King Buxton had before it, Robo Doc drove onto Matilda's forks. However, Robo Doc fell onto its back, and slammed into reverse, putting the large side of its wedge against Matilda and pushing. This succeeded in raising Matilda's wheels off the ground, and Robo Doc held on to the end. With Rottweiler being pushed back to the entry gate, Robo Doc qualified for the Arena, where it faced King Buxton.

King Buxton pushes Robodoc

King Buxton rams Robo Doc from the side

Robo Doc was hit side on by King Buxton, who shoved it with little trouble, into the PPZ, where it was buffeted by the pendulum, Matilda and Dead Metal. Robo Doc then rammed King Buxton, but was easily overpowered and pushed into Shunt before its own lifter could get put into play. After having some close shaves with the pit, almost reversing in and then almost pushed in by the combined efforts of Matilda and King Buxton, the match went to the judges, with Robo Doc ending the fight upside down. Since King Buxton had been the more aggressive throughout, it was given the win and Robo Doc was eliminated from the competition.

"Your robot was designed so well, even when you were flipped, it got a bit more effective because the spike was lower! Unlucky."
— Craig Charles to Mike Franklin

Robo Doc was also nominated for the Best Design award, but lost to Razer.
