This years competition for Vex sack attack I have to create a one minute autonomous, but i dont think I have have the stuff to pull it off.
this is what i am working with line trackers, encoders, and a vex lcd display, will this be enough to do a one minute autonomous or do i need more stuff?

It depends a lot on what you want to do. Those sensors work fine for high school, and there's no reason that they won't work for college as well. Also, you can make your own sensors if you feel that the ones available to you are not enough.
*Assuming you're competing in the Sack Attack college challenge.
