As was mentioned, we use a wheel with 2 light sensors mounted on it (2 sensors allow you to determine both distance and direction of rotation). As for the wheels spinning without the robot moving, this is a problem to consider however in practice it doesn't happen unless we change direction on the ramp grid (causing a momentary wheel slip) or if we run into something completely immovable (like the field border).
