Performance Improvement of Magnetic Position Sensor for Robicle(Robotic Vehicle)

Abstract

In this paper, the performance improvement of a magnetic position sensor for autonomous vehicle using 1-axis magnetic field sensor array is described. In the data of magnetic marker's position versus its magnetic fields, there is a region which is reasonably linear. The proposed system uses the region to detect marker's position from magnetic field. The proposed magnetic position sensing is verified by the experimental results.
