Toxin was a super-heavyweight robot built by Team Terrafonics for Series 3 of Robot Wars. After the team initially attempted to enter it into the Middleweight Championship and later the main series, it was subsequently selected to compete in the accompanying Super Heavyweight Championship. However, Toxin would ultimately never appear in the series, as the competition was cancelled before the battles could take place.


Toxin at the Series 3 auditions without its armour

Toxin was a octagonal-shaped robot armed with a rear wedge and a front pair of lifting forks. The original concept for it was a domed robot made out of a large wok, similar to famous American competitor Blendo, equipped with a lifting arm and an arm-mounted sawblade which swung down through the lifter. However, the sawblade was discarded, as Team Terrafonics found it hard to obtain and even harder to manufacture.

Toxin took six months to build, and was driven by a pair of wheelchair motors that gave it a top speed of between 5-7mph. The robot was originally powered by two 12V, 24A batteries, with its lifter powered by a low-pressure pneumatics system which enabled it to lift 350kg. Toxin was armoured with an 18mm plywood base, 1.5mm steel at the front and back, 5mm steel on the top, and 12mm steel bent to form its front scoop.


By the time it attended the Series 3 auditions, Toxin was missing its front armour, and Team Terrafonics found that the robot was severely overweight. Craig Danby says the robot was initially built to challenge for the Middleweight Championship title held by Hard Cheese, but the team "overshot" the 45.4kg weight limit. Without its armour, it weighed 97kg, a total of 17kg over even the heavyweight limit at the time. Despite this setback, Derek Foxwell commented that Toxin was well-made, compelling the team to install smaller batteries - saving nearly 30kg - and calculate how many holes they should drill into the robot to bring its weight down further. However, the Robot Wars producers called the team to tell them not to sacrifice too much weight, as they had selected Toxin to compete in the Super Heavyweight Championship. The team complied and continued to increase the robot's weight, reaching approximately 150kg by the end of the build.

Filming for Series 3 was delayed for various reasons, which meant Toxin was finished long before filming. Following a behind-the-scenes accident in The Pits, the Super Heavyweight Championship was cancelled - along with several other competitions - and Toxin was thus unable to compete in Robot Wars.

Outside Robot Wars[]

After failing to enter Robot Wars due to the cancellation of the Super Heavyweight Championship, Team Terrafonics later considered entering Toxin into BattleBots, as it would have been eligible to compete in the heavyweight division with the smaller batteries. However, they ultimately decided not to attend, as they deemed that it would have been too expensive for them to travel to America.
