For a nonstrafing bot you have to correct all the way to the target. Given I still think the camera is the best choice overall, line trackers will work almost equally well as the camera on a non strafing bot.

With the camera I look at the target not the lines. Where the refresh rate is not great, capping with the camera will be more accurate. Even their pretty slick line tracker in the video was jerking around quite a bit. If i was to attempt to cap with a line track I would require a gyro for it to be accurate(75% success rate is typically my bar) with the camera you do not need a gyro because you are looking right at the target.

I believe the average automated camera cap will be faster than a human cap, and more accurate than a line tracker cap.

Oh! I totally misunderstood what you meant about camera tracking. I thought you meant tracking the line with the robot. But with your method, be careful to watch out for other robots and to not run into other robots... I know from experience, I was looking straight ahead and I did not see the bench right in front of me...
