GEAR has some AndyMark hall effect encoders that can be attached to AndyMark DC motors to measure distance traveled by a robot.
The purpose of the 2 channels is to make it possible to detect rotation direction. If you only want to track distance in one direction, it is only necessary to use one channel. As the motor spins, the channel lines will output pulses of +5 volts (7 pulses per one rotation for each channel, 90 degrees out of phase, a so-called quadrature encoder design). You can use an Arduino to supply power to the encoder and to program it. The tutorial linked below should be helpful with programming.
Here is a sample Arduino code that works with the AndyMark encoder:
