So this is how FIRST is killing dead reckoning? Hooking these up next to gears tell you how far you've gone, the accelerometer could tell you if you were straight and now we can drive the robot any direction and know exactly how far. Right?

No. To be honest it's still dead reackoning and you still do not percisely know where the robot is with 100% certainty.
