Abstract
Recently, application of robots has been required in disaster sites. Rescue robots were applied to disaster sites and they had obtained various results for the Great East Japan Earthquake. However, as a disadvantage the available range is limited because remote control type robots become impossible maneuvers if communication is terminated, due to a fault used range. We consider that is necessary for robots to autonomous work with the ability of self-determine action in order to avoid these problems. Generally, GPS is used for autonomous mobile robots that are working in outdoor environment. However, localization accuracy is depended strongly on the type of a GPS receiver. Moreover, it remains problems by blocking of signal that localization possible environments is limited with blocked as tall buildings or trees. This paper, present a novel control method using GPS and 3-axis geomagnetic sensor for autonomous mobile robot used in outdoor environment. The experimentally obtained results show that accuracy of the autonomous moving is improved by correcting position and orientation data measured from features results.
