3D map building for slopes based on modeling of mobile robot

This paper proposes a robust 3D (dimension) map building system for a mobile robot using a LRF (Laser Range Finder). Instead of the expensive and bulky 3D laser scanner, the LRF can be utilized and installed on the mobile robot for the map building and the autonomous navigation. This research, the scanning operations are performed while the mobile robot moved on the slanted surface and ground without stops. The motion of the mobile robot is transformed into the scanning surface in the process of forming the 3D map. The experimental results reveal that the improved accuracy of navigation for the mobile robot in the real time scanning of the environment.
