ThundeRing

".. a machine designed to set a new benchmark in robot design. It’s unusual shape is engineered to fend-off attacks from rambots, flippers, spinners and axes, while presenting its opponents with a fearsome 1m diameter rotary axe."

- The Team Dark Star Website

ThundeRing was a robot that failed to qualify for Series 7 of Robot Wars. It was an Axlebot, with a thin body, very large wheels and armed with a 1m long rotary axe.

The wheels were very far apart on the robot to prevent flippers getting under the robot properly. The wheels were also very thin, only 30mm in diameter.

The robot had 11 sponsors. It is currently unknown how it failed to qualify.

Team Dark Star had previously failed to qualify for Series 6 with a machine called Twinkle-Twinkle, a rectangular box-shaped robot with a horizontal spinning disc. After losing its qualifier to three unknown opponents with spinning weapons, flippers and axes, this inspired the team to build a robot that could resist all these methods of attack.

"Following this thrashing the Team was faced with a dilemma, admit defeat and retire from robot building or design a new robot that would laugh-in-the-face of its opponent, irrespective of their design and weapon system, before dispatching them to robot Valhalla. Naturally, we chose the latter."
