Development of an Autonomous Weed Mowing Small Robot

-Self-location identification by a tracking laser rangefinder-

Abstract

GPS is used for identifying the self-location of the robot outdoors. GPS cannot be used when the radio wave for GPS signals from satellites are shut off by mountains and buildings. Therefore, we have developed an instrument that measures the position of a robot instead of GPS. The instrument is named a tracking laser rangefinder. We manufactures a prototype autonomous mobile mowing robot and carried out performance test. The robot could trace the straight line paths, but slightly derailed the circle paths.
