Billy,
That kind of damage tells me there is something else wrong. I would first look for a shorted regulator and/or the possibility of a short to chassis in the mounting. If you find the chassis short, that indicates another part of the robot is also contacting the chasis and passing current throught the frame and through the little trace on the IR board. When you replace the fuse (board trace) with a bigger fuse (the wire) something else will have to give. Let us know what you find.
