Improvement of Magnetic Guidance System using 2-Axis Magnet Sensor Array

This paper proposes a magnetic guidance system using 2-axis analog magnetic sensor. This magnetic sensor has the advantage of low estimated position error than using digital magnetic sensor and it’s possible to estimate yaw angle of mobile robot. Estimated yaw angle assists the guidance system for improved driving stability. Simulation results show that estimated position has low error and that mobile robot is driven with better stability.
