ORAC was a box shaped robot that competed in Series 2 of Robot Wars. It reached the Arena Stage of its heat, but was "pepper potted" and burned on the Flame Pit by Killertron, who went on to reach the Grand Final.

The team returned for Series 3 with Orac's Revenge, It was less successful than its predecessor, as it was quickly dumped in the pit in the first round of its heat by another eventural Grand Finalist, Steg-O-Saw-Us.

The name ORAC comes from the computer in the TV show Blake's 7, a show which Technical Consultant and Judge Mat Irvine worked on as a visual effects designer.

Versions of ORACEdit




ORAC was a yellow box-shaped robot, with huge wheels. Costing £400 and built over five months, it featured wheelchair technology, including a total of four wheelchair-style casters, and was powered by two car window motors. Its weapon was a 9' circular saw on the end of an arm, and two hardened steel front lifting chisels. ORAC was quick for its time at 10mph, but had a high ground clearance, and was relatively light at 55.5kg.

Orac's RevengeEdit

Orac's Revenge was a new robot that was painted green with scales, box shaped with 4mm thick aluminium, strengthened in vulnerable areas with thick polycarbonate and armed with a red pickaxe with interchangeable blades. It featured a green scaly design with a large face on the front. The pickaxe was quick in activation, as was the robot itself, but its damage output was still low.

Orac's Revenge was originally named Hammerhead, and its body was painted yellow with red stripes rather than green, and its spikes were not painted. In this form, Mentorn initially rejected it from Series 3, but for unknown reasons it later managed to qualify, possibly after the repaint and rename. Another robot called Hammerhead also qualified for the Third Wars.

Orac's Revenge attempted to enter Series 4, where it was virtually unchanged from its Series 3 design. However, it failed to qualify.

Robot HistoryEdit

Series 2Edit


ORAC completes the Gauntlet

ORAC began in the Gauntlet by going up the ramp. It avoided Shunt and completed the course very quickly. No other robot completed the Gauntlet within that heat, and ORAC progressed in first place.

Orac trial

Matilda drops ORAC over the edge

ORAC's Trial was King of the Castle, in which it faced Matilda and Shunt. Shunt drove off the ramp by mistake after 6 seconds. Meanwhile, Matilda picked up ORAC and span around with it, and eventually dropped it off after 28.93 seconds. This was enough to keep ORAC in because Schumey only lasted 9.40 seconds.

Killertron vs Orac

ORAC is burnt over the flame pit

In the arena semi-final, ORAC faced Killertron. The fourth seed began by missing the yellow machine with its axe several times. ORAC was then hit with an arena spike, and became immobilised. Killertron proceeded to punch holes into it, and it was left smoking on the flame pit.

Series 3Edit


Orac's Revenge is dumped out by Steg-O-Saw-Us

The pitted Orac's Revenge is attacked by the House Robots

The Oracles returned in the Third Wars with their new robot Orac's Revenge. This time, it didn't last very long, the original reserves Steg-O-Saw-Us resisting its axe, despite it coming down constantly at such a rate, Steg-O-Saw-Us was ramming it into the arena walls with little to no resistance. Steg-O-Saw-Us then quickly pitted Orac's Revenge. Despite this, the House Robots still came in to cause more damage to the pitted machine.

Outside Robot WarsEdit

Orac's Revenge made various appearances at live events away from Robot Wars, including a battle with Splinter.

In 2016, the team stated that they would have liked to be part of the new series, but would be unlikely to build a robot in time. They still own both versions of ORAC.

"I received an email to my robot website about the new series from Mentorn today. Had a look at Orac and Orac's Revenge sitting in the garage, looking in a very poor state. Will probably have to make something new, but 2 months is a very tight timescale, not sure if I could build anything presentable."
— Peter Reynolds on the FRA forum


  • In both of ORAC's appearances, it lost in the heat, in its first battle, to the eventual fourth place.
  • After Series 4, the team built a autonomous submarine powered by renewable energy.
"We are designing a small autonomous submersible craft to cross the Atlantic ocean and return using only renewable energy. We have 4 engineers/scientists working on the project so far and we estimate it will be a 2 year project. Basically we are going to chuck it off brighton pier and it will page us 7 months later when it gets back!!"
— The Oracles on their autonomous submersible[1]
