In this paper, device development for AGV using magnet navigation and method of magnetic localization method are described. The most commercial AGV is using magnet navigation. This is more stable and lower cost of sensors than different navigation systems of AGV. However, the commercial magnet navigation devices use magnet hall sensor of digital type and those accuracy are decided by the number of magnet hall sensor and interval. The interval is about 10mm generally because interference occurs in the case of close interval, but the AGV using this interval has low accuracy. This AGV doesn’t matter in straight driving, but occur breakaway or false operation in curve driving. Therefore, we create an magnet navigation device using magnet hall sensor of analog type and design fitting functions with the experimental results of magnet hall sensor in the work environment. Based on this, this paper proposes the method to detect magnet navigation line. In the result of proposed method, localization method accuracy is improved more about 16.73mm by this method than the commercial magnet navigation device and space to detect magnet navigation line is larger.
