The approach is the right beginning. The term for it is dead reckoning. It has some problems regarding its precision. Next steps in increasing precision would be sensor adding optical flow or other sources for distance travelled some using sensor fusion technique. You do not have a redundancy problem. If you use the same sensor signal and transform it into ...

Given that you are using 2 dc motors, I'm guessing you are using a differential drive configuration. Your intuition about the algorithm is good. The encoders on the motors along with some physical/mechanical measurements (wheel radius/circumference and wheel base) are used as input to a kinematic model, in this case the unicycle model. Using this, you can ...
