A self-localization method for omnidirectional robots

This paper introduces a self-localization method depending on two signposts for onmidirectional robots. In the real environment because of keeping out or the intensity of the ray, the robot can´t find enough landmarks for self-localization. But in the past the robot needs at least three signposts for self- localization. So, depending on the advantage of the onmidirectional vision, this paper gives a new method using two signposts for self-localization. This method reduces the searching time in the Robocup competition or robot navigation. The experimental results show the method is very precise.
