Cerberus

Cerberus was a vaguely reversed-wedge robot that competed in the third and fourth series. It was designed to look like a dog, and was named after the three-headed dog of Greek Mythology. Its main weapon was originally a circular saw, but this had to be removed as it was made of hardened steel, which was prohibited (Pussycat had recently been disqualified for using one). Instead, Cerberus used its ramming head and wedge like tail to defeat its opponents. Later added was a blade-like tongue and two side blades that acted as a srimech.

Cerberus made the heat final of Series 3, but lost in the first round of Series 4. Although it never competed in the main competition after that, it did feature in both Extremes, with varying degrees of success. It also represented Cyprus in the First World Championships.
