High precision markerless localization of mobile robots in indoor industrial environments

The topic of this PhD thesis is the precise localization of mobile robots in industrial environments based on laser range scanning and without installed markers. During the research, new localization methods were developed to achieve the accuracy required within specific industrial applications that had previously been achieved only by markers. Two methods for localization using a laser range scanner were investigated, with the first method improving the accuracy of the existing AMCL-based methods, and the other achieving improved accuracy by fusing data from laser scanners placed at different height levels of the mobile robot (industrial forklift). New methods have been implemented on a real autonomous forklift using ROS (Robot Operating System) and their performance validated in realistic industrial conditions. Robustness of algorithms has been tested under conditions of fast and slow changes in the environment as well as resistance to possible accumulation of errors during long-term robot movement.
