I do not understand why there is a need for sensors.

I do not even know if the Banner Sensors even work on the white refective tape.

If using sensors, there would be a need to accurately space the sensors apart to "see" the white line.

The most basic solution is to have the robot go forward a bit, turn in an arc to a specific counter, and then go forward again.

A simple toggle switch wired into the digital input tells whether the robot turns left or right.

To go forward, make code for the robot to go forward until a counter. To turn, make one wheel spin faster than another. To go forward again, another counter.

Our team was considering mounting some sort of sensor on the wheel to see how far it travelled. Just a touch sensor and studs placed at specific intervals on the wheel.

Why is having an internal counter unreliable?

Autonomous-mode seems one-dimensional to me. This looks like the best solution. Get up the ramp the fastest, knock the boxes down. Trying to find the reflective tape with the sensor spinning around? Good luck.
