Navigation of Unmanned Vehicle Using Relative Localization and Magnetic Guidance

Abstract

In this paper, a navigation technology of an unmanned vehicle using relative localization and magnetic guidance is proposed. Magnetic guidance system had been developed as a robust autonomous driving technology as long as magnetic fields on the path are detected. Otherwise, if magnetic fields were not detected due to some reasons, the vehicle could not drive. Therefore, in order to overcome the drawback, we propose that relative localization would be combined to magnetic guidance system. To validate the usefulness of the proposed method, a robotic vehicle was set up with the magnetic guidance system and the relative localization. In addition, the unmanned driving test was realized on the road without the magnetic fields so that the proposed method is verified by the experiment.Key Words : magnetic guidance system, relative localization, unmanned driving, robotic vehicle

Vision Sensor-Based Driving Algorithm for Indoor Automatic Guided Vehicles

“…In the first type of system, most AGVs track buried cables or guidepaths painted on the floor. One of the most popular types of navigation is based on the use of a magnetic tape as a guide path where the AGV is fitted with an appropriate guide sensor so it can follow the path of the tape [1]. However, it is not easy to change the layout of these guide paths and any breaks in the wires makes it impossible to detect the route.…”
