Re: Advantage given by succesful autonomous mode

First off even an unexperianced team can still do useful stuff with autonomous even if they are not scoring (and experiance has nothing to do with it, it's all skill and knowledge) such as setting up to collect ringers when autonomous is over, etc,etc, etc... Next, the camera can track more than one target, and the targets are 90 degrees apart, so if it can see two, it drives forward until it only sees one, ta da! Next you forget about how little the shaking of the spiders actually matters, if you do the math and take into account that the keepers are beveled, then you find out that you have a little more than 6 inches of play in any direction. And lastly, if you set up keepers during autonomous, then they can't be blocked, but can be used to make chains during teleoperation...

My 2 cents...
You are overlooking a few things, it is true the camera can track two targets, but how do you know WHICH of the two targets your ally will go for???

The rack is rotated randomly and there is no reliance on what the other teams program might do,
and while I agree, it is certainly possible and not even ridiculously hard to figure out a way to work this out. I just don't see many teams doing it. You talk about implementing vision like it is a very simple task, but realistically it is not.

Last year I saw about 50-60% of teams do something in autonomous mode (at our regionals) most teams were unable to accomplish anything other than defense. If only 15-20% of teams can program a robot to go in a straight line and dump balls in a goal efficiently what do you think that says about implementing a succesful working vision system?

Lastly you said that if you "do the math" the ringers have only 6 inches of play in each direction.
Do you know how incredibly much that is? you are attempting to put a ring with a hole of 13-14" (?) diameter onto a rack whose cap is 10" in diameter.
I don't think 6" is "very little".
Robots that cannot score in autonomous will move the rack and make it incredibly difficult if not impossible to score.

Lastly, experience does have something to do with it. I'm not saying a rookie team can't pull it off because you're right skill and knowledge will result in sucess. However the vision system is one of those things where it is of great benefit to teams who have the resources to have a practice robot to test code on and prototype. Most rookies scramble to get the bots together, and don't have time. I'm not saying vision is a bad thing but I think more options for play during autonomous would be better (other than just defense) ... I think 2006 was a great example: You could score in side goals, block or score in the center goal
