- a combination of all of the above
- using a "follower wheel" that has a wheel speed encoder (for distance traveled) and an angle encoder (for current direction of travel).

If you want absolute position over the whole duration of a match, I don't think encoder wheels will cut it this year, with all the bumps and various defenses, not without re-zero-ing repeatedly.
