TOD (Short for Triangle of self-Destruction) was a 450g robot from Finland built by Team Final Destination. It was a invertible, three-wheeled, translational drift spinner. The robot moved by spinning up, to speed, where it would move across the arena because it was deliberately imbalanced. Each wheel was driven by a servo, and it had blades that retracted from the corners of the triangular chassis. 
Despite generally proving to be completely uncontrollable, TOD performed well in competition, never failing to reach the quarter-finals, and even placed third at its first ever event. TOD was retired in 2007 after performing progressively worse, and worse since its 2006 debut after only three events.
