| Outline of Final Research Achievements |
An environmental magnetic field, magnetic field that occurs in the environment, exists anywhere on earth and if it can be used as a landmark, it is possible for robots to autonomously navigate anywhere. In this study, we aimed to develop a navigation method using this environmental magnetic field. The magnetic map was built by recording position of the robot and the environmental magnetic field detected by 3 magnetic sensors, which were installed in parallel at the front of the robot, 0.2m up from the ground level. The robot then navigated accurately by matching the magnetic sensor readings against the environmental magnetic stored in the magnetic map. Moreover, we successfully enhanced the robustness of the proposed navigation method by renewing the magnetic map during the autonomous navigation to cope against changes of the environmental magnetic field caused by displacement of magnetic materials such as buildings, vehicles, electric machines, and so on.
