Research of Magnetic Tracking Navigation of Patrolling Robot on Fully Mechanized Coal Face of Coal Mine Underground

The paper proposed a scheme of magnetic tracking navigation of autonomous mobile patrolling robot on fully mechanized coal face of coal mine underground. The scheme defines magnetic tracking material and magnetic sensor of the robot as stripy magnet with high intensity magnetic and model MS-324 tongue tube through experiment, it defines installing position and working process of the tongue tube of the robot with example of collecting underground image information by wheeled robot. The experiment result showed that the robot can moves stably when distances between two tongue tubes are 40 mm.
