MouseTrap

The Mousetrap team were competitors from Series 3-5 and 7. During the team's campaign, they competed with three very different robots. Mousetrap, who competed in Series 4 and 5, was a wedge-shaped replica of a spring mousetrap, with the trap itself being the weapon. For Series 5, a blade was added to the trap. Of these three machines, only Mousetrap had any great degree of success, reaching the semi-final of Series 4. Both of their other robots were beaten in Round 1.

Triterabot
Triterabot was a triangular shaped robot that competed in Series 3. It had a spike on each corner, was invertible and could also emit a smokescreen.

Black & Blue
Black & Blue, from Series 7, was a clusterbot, each machine a small invertible box with a spinning drum.
