Breaker Box, the so called spinner killer, super simple design but effective. Built by Jim Smentowski who was all about really big vertical spinners (Backlash/Nightmare), so he must know what it take to take care of one.

One of the secrets is to drive well, trying to only get hit on the biig Ti scoop and get on the side of spinners. So, practice alot your driving.

Hope this helps, i would love to see some one build a robot that scares spinners.
