Robot statistics correct as of its most recent appearance on the show
"The construction of Wedgehog was very 'make it up as you go along'. We had a vague idea of the set out of the components we had, but no exact designs were ever made. I find this approach much more fun and much faster as long as you know what you're doing."

Wedgehog was a lightweight robot that singularly participated in the first series of Robot Wars. It was a black aluminium wedge, with a pickaxe as its weapon. However, this weapon was not very powerful and was referred to as a "toothpick" by both Jeremy Clarkson and Jonathan Pearce. Also the robot travelled at 4mph and ran off two 9.6V domestic electric driils. Wedgehog was substantially lighter than the rest of the robots in its heat; it defeated Dreadnaut in the Arena, who was 64kg the heavier. However, it lost in the heat final to Robot the Bruce.
Nowadays, Wedgehog is retired and is shown at Robots Live events. However, only its shell is displayed, without the internals. It is currently in the posession of Team BlazerBotics.
Wedgehog fought in Heat C of the First Wars. In the Gauntlet, Wedgehog broke down a metre from the end of the Gauntlet after taking the maze and becoming impaled on a spike, however this was still more than enough to make it through to the next stage, placing third of six on the leaderboard.
In the Football Trial, Wedgehog had attached panels to its front wedge to help control the ball. It was awarded the second goal because it had touched the ball last of the remaining competitors before goalkeeper Dead Metal inadvertantly pushed it in. Wedgehog went through to Heat Semi-Final, here, it fought Dreadnaut, who'd suffered from reliability problems twice before this stage. Dreadnaut definitely had the weight advantage, but just a few bumps and bashes from Wedgehog, and Dreadnaut's engine burned out, it was declared immobile and Wedgehog was put through.
Finally, it met Robot the Bruce in the Heat Final, the first product to come out of Team Chaos. After putting up some resistance, the heavier and more powerful Robot the Bruce eventually caught it from the side and bulldozed Wedgehog onto the grill, ending its challenge as it was unable to get away. A short time later, after it had been declared immobilised, Wedgehog suffered fierce attacks from the incoming house robots Sergeant Bash and Matilda, taking damage from their cutting weaponry.
