The research of floor-tiling robots aiming to replace the artificial floor tile installation, which is a trend in the development of construction automation. Modular design of the robotic floor-tiling system used embedded PC as the main controller, which has several advantages, such as reliable system performance, convenient modular communication, and simple function improvement. The measuring and positioning system of robotic floor-tiling consists of multiple subsystems. The task calls of each subsystem are allocated in real time through control flow and control algorithms. Feasibility of the measuring and positioning system is proved by test run and the future works are discussed.
