Any time the target doesn't move after you've placed your bot, AND you can start your robot where you want, dead reckoning will work. If no interaction between red/blue robots is allowed, dead reckoning can't be defended.
2003 was the start of auto. You needed to be first to the top of that ramp.
2004 the target didn't move, but auto could be defended by cross field ramming.
2005 i didn't compete, and my memory is fuzzy, but was the first year we had the CMUcams. it was awful, as the targets were passive, and the arena lighting varied wildly.
2006, they switched to the green cold cathode boxes, which were much more reliable to detect, but the target didnt move, so no need to use them
2007, the rack moved after robots were placed, but typically didn't move a whole lot.
2008, the IR remote could be used to tell your robot where the balls were. most teams just dead reckoned.
2009, trying to dump in auto usually meant you got your own trailer beat up on by an HP
2010-2013 no game pieces, robots, or targets are moved before auto, AND red/blue interaction during auto is against the rules.

This is a little inaccurate. You weren't always allowed to position your robot exactly where you wanted it so you couldn't be sure that your robot started in the same spot each time. In 2012, we needed vision in auto. Our strategy was to get to the center bridge and get the balls first, so we would be traveling very quickly when we hit the bridge, causing our robot to get misaligned. When we drove forward to the key again, we usually would be 2 to 3 feet away from where we started, and we needed the camera to line up with the target.
Also, many other teams have used vision as part of their main strategy. In 2006, wildstang had a nifty turret thing that was always pointed at the goal whenever it was in range so that they could get the balls in at any time. Also, 118 used a camera very well in 2012 with their shooter because it would let them shoot from anywhere near the key without having to line up.
The point is, for some games and some teams, vision is a huge part of the game.
I know teams used vision to line up for a full court shot this year, and teams also used vision to line up with the legs of the pyramid.
