Using of electronic compass
in navigation of mobile robot
Compass is the popular instrument used in navigation. In the past, compasses were used to determine the coordinate of ships on the sea and position of people in the deep forests. Nowaday with the development of technology, electronic compasses contribute the excellent solutions in navigation, especially in navigation of mobile robot. Electronic compass with many advantages - compact dimension, high resolution, easy to use and high effect - will be the optimal solution in determining angle of goal point. By giving the right angle of goal to the controller of robot, electronic compass along with other sensors such as encoder and ultrasonic, infrared sensor help increase the result of navigation. In this paper we suggest using of electronic compass in mobile robot navigation to reduce the errors. This method has higher effect and the process of navigation become simplier.
