- "Grunt is definitely lean, mean and deadly keen."

Grunt was, in fact, not a real competitor robot, but rather one of three robots supplied by the Robot Wars team in order to make up the numbers, as only 33 true contenders had taken part (the other two being WYSIWYG and Eubank the Mouse). Grunt was in fact driven by the son of Robot Wars judge Eric Dickinson, and had been created by technical consultant Derek Foxwell.
As a direct result from this, Grunt was not permitted to pass through the Trial stage. Thereby, after completing the Gauntlet in the second fastest time, it drove straight off the Sumo platform in the Trial. This made it, along with the other Stock Robots very unpopular with others teams, particularly Barry, who was eliminated in the Gauntlet and denied the opportunity to test its strengths in the Sumo.
- "We were kicking ourselves. It would have been easy for Barry; no problem. When it came to Grunt's turn (watch out for this on TV) he drove straight off the edge. Why couldn't he have fallen in the Gauntlet so at least we would have been given the chance to show up the house robot, Shunt?"
- — Daniel Parry of Team Power, on Grunt's exit
Originally, two identical versions of Grunt were built, both of which took part in the 1995 UK Open Competition. At various stages throughout the competition, each version fought fellow Stock Robot Eubank the Mouse as well as established US Robot Wars competitors The Master and La Machine.
Grunt was a relatively long, thin wedge shaped robot design to look like a battleship with no weapons of which to speak of. It was also very fast for its size at 15mph, and had a novelty lightbulb on top.
Grunt started very quickly speeding past the house robots in the gauntlet and reaching the end zone. In the Trial, which was Sumo Basho, Grunt drove around Shunt, but then drove off the edge of the ring, thus eliminating it, much to the distaste of the Barry team, whose robot had lost to Grunt, as they felt it would have done better in the sumo.
- "Not so nice, over in a trice! And Grunt goes in spectacular style."
