Radiation intensity mapping in outdoor environments using a mobile robot with RTK GNSS

Two gamma-radiation distribution field measurement experiments are described in the paper. Because of principally dangerous nature of gamma-radiation, the idea was to extensively use robotic systems and automation to minimize human exposure to radiation. The experiment setup as well as Orpheus robotic system are described. Algorithm to autonomously navigate the robot based on RTK GNSS in predefined area is presented. The algorithm was exclusively developed for Orpheus robot, considering its tank-like drive configuration.
