Trajectory tracking method using low cost magnetic sensors

This paper describes a trajectory tracking method using low cost magnetic sensors. So far we have worked on using magnetic field that occurs in the environment for mobile robot´s navigation. Even if we have proved that the mobile robot equipped with our method can travel over a distance of 1km, it is questionable whether the method depends on a high profile magnetic sensor. In this work, as an illuminating research, we apply low cost magnetic sensors in our trajectory tracking method and we then compare the result with a result obtained from method with a high profile magnetic sensor.
