Trajectory tracking method using low cost magnetic sensors

摘要

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.
