Development of Intelligent Sensor for Magnetic Guidance System of Robot and Vehicle

摘要

In this paper, development of intelligent sensor for magnetic guidance system of robot and vehicle is described. A position sensing is very important in a guidance system. A vehicle or a robot was identified their location by magnetic marker in the magnetic guidance system. A magnetic sensor have a characteristic of re-magnetization that when the sensor exposed to a magnetic disturbing field, the sensor elements are broken up into randomly oriented magnetic domains that leads to sensitivity degrading. This problem is solved that designed hardware. Also, offset of the sensor eliminated to sensing algorism. The proposed sensor is verified high sensitivity state for measuring magnetic fields through experiment.
