Robotic façade cleaning system for high-rise building

There is a considerable increase in the number of skyscrapers in the world due modern development of construction technology. Current maintenance work for high-rise buildings mostly uses conventional ropes and scaffolds that pose a high risk of accidents and exhibit poor performance and efficiency. There is a demand to develop an automated cleaning system that can reduce accidents and improve the maintenance efficiency of the conventional high-rise building façade maintenance systems. In this paper, we demonstrate an automated façade cleaning system that can reduce accidents and decrease labor costs. We propose a new technique of cleaning mechanism for façade cleaning in high-rise buildings; the system consists of two Robots working for the cleaning process; the lifting robot or the Roof Top Robot (RTR) and the Cleaning Robot (CR). The RTR is designed to lift the CR vertically on the façade in the upper and lower directions; the horizontal direction is also performed by the end of each vertical motion. The CR acts as the main cleaning unit, which utilizes different cleaning modules that is required for the cleaning quality. The performance of the proposed cleaning system is evaluated experimentally; however, additional study should be necessary for more complicated facades architect designs.
