The problem seems to be that there are no vision lights on the corner goals. There is no green light above the corner goals for sure, and unless I am very much mistaken there is also no infrared source (any infrared beacon) near the corner goals. So, can anyone think of any way of making an autonomous mode that will have the robot drive up to a corner goal? I have heard something somewhere about it being possible to use the infrared sensors to detect obstacles, and thus being able to detect a hole in a wall. Is this true? Is it possible? If so, how difficult would it be to implement?

Also, it has been suggested to me that I could use the CMU cam to look for shapes. Then, I could look for the red or blue rectangle surrounding the corner goals. I am completely new to using sensors: in previous years, our robot had no autonomous mode. I believe that the CMU cam idea will not work because there are lots of red or blue rectangles on the field, for instance the starting positions. However, I would very much appreciate someone else's opinion on this and any ideas on how to implement the autonomous mode I described.

we align the robot straight at the goal then i tell the camera to track about where the green light should be once it locks on it drives forward until the light goes out of range, once the light is out of range i will test to see how far it still has to drive to get to the goal and tell it to do that using dead reckoning.
