Electromagnetic sensor navigation system of robot for high-voltage transmission line inspection

Abstract

A method of electromagnetic sensor navigation of inspection robot for high-voltage transmission line is proposed.This method adopts an theory of comparatively detection,plots out the space into different areas by sensor arraying suitably,figurs out the position and direction of the robot by some specific arithmetic based on the electromagnetic sensor output.Experiment in the laboratory and on a locale high-voltage transmission line indicates that the electromagnetic sensor can work reliably,the method of navigation is feasible,it's precision is 10mm,and the system can satisfy the requirements of practical use.
