Claim 0:
1. A method of operating a mobile construction robot which is configured for machining or finishing an architectural construction site, comprising the steps of:
placing an optical tracker on the architectural construction site;
parking a driving platform of the mobile construction robot in an area of the architectural construction site;
moving an end effector of the mobile construction robot in a first position and a second position by controlling a robotic arm mounted on the driving platform;
measuring the first position and the second position of the end effector relative to the driving platform using a sensor mounted on the robotic arm;
tracking an optical marker mounted to the end effector in the first position and the second position of the end effector with the optical tracker and measuring the first position and the second position of the optical marker relative to the optical tracker with the optical tracker; and
determining a position and an orientation of the driving platform based on the measured first position and the second position of the end effector relative to the driving platform and the measured first position and the second position of the optical marker relative to the optical tracker.
