In recent years, the number of high-rise buildings has been on the rise. As buildings have become larger in scale, significantly different issues related to their construction and maintenance have emerged. In addition, the automation and mechanization of the cleaning work for the curtain wall, one of the most frequently-performed tasks in building maintenance, is required as a fundamental measure. For this reason, a guide-rail cleaning robot system is emerging as one of the measures in response to external factors, including gust. Therefore, this is a preliminary study for the automation and mechanization of the curtain wall cleaning of high-rise buildings, and aims to derive the basic units and prepare for the concept of the guide rail. It is expected to serve as precedent research for the development and operation of a curtain-wall cleaning robot, and to prepare the basis for an final design of optimal guide rail.

Recently increasing high-rise building cleaning on the exterior walls of high-rise buildings, there has been increased interest. Building exterior cleaning is cleaned by a cleaning robot and how to clean the exterior walls of the building and exterior glass cleaned by personnel. Number of stories in the building increases, being carried out by personnel cleaning the outer wall as there is a limit order to overcome this method. therefor, this study is a new exterior wall cleaning device has been proposed.

Most of the building exterior wall cleaning robots use a water jet device for spraying water. However this method is sprayed excessive water usage than water quantity required for cleaning. And setting weight of the water pump cleaning device increase the weight of the building exterior wall cleaning robot. Therefor, this paper suggest that the mechanisms scatter minimal cleaning water using a spinning device of the building exterior wall cleaning robot.

When the number of skyscrapers are increased in the domestic, it has increased the need of the outer wall cleaning robot. However, it does not exist the construction specification of the outer wall cleaning robot in the domestic. it is difficult to apply in the domestic that the outer wall cleaning robot. For this reason, it raised the need of the construction specification. And it is urgent that the construction specification of the outer wall cleaning robot is needed to develop in the domestic. Therefore, this study aims to propose the construction specification framework of the outer wall cleaning robot. In the future, this study will be based on the development of the construction specification on the outer wall cleaning robot.

With the development of technology, there has been a considerable increase in the number of skyscrapers in the world. Accordingly, there are increasing requirements with regard to maintenance, such as cleaning, painting, and inspection. However, it is extremely dangerous to work on the walls of buildings, and falls from buildings have accounted for a large proportion of construction accidents. In particular, as the number of buildings with irregular shapes increases, the accident rate during maintenance work has increased each year, with most accidents leading to deaths. An alternative solution must be developed with the commercialization of automatic systems. In this study, fundamental research has been conducted for drafting and commercializing an automation tool with a built-in guide system that can perform cleaning.

As residents and building owners demand maintenance that is required to achieve sustainable building performance, efficient building management methods are required. Even though the demand for maintenance systems is increasing, current maintenance work for high-rise buildings mostly uses conventional ropes and gondolas that pose a high risk of accidents and exhibit poor performance and efficiency. Thus, there is an urgent need to develop an automation robot system that can reduce accidents and improve the maintenance efficiency of the conventional high-rise building façade maintenance system. As a preceding work for the development of an automation robot system, this study classified and analyzed the work processes of actual construction sites and proposed basic techniques for the work mechanisms of the robot system by investigating the motions of cleaning workers.

In this paper, we present the hull blasting machine with vision-based weld bead recognition device for cleaning shipment exterior wall. The purpose of this study is to introduce the mechanism design of the high efficiency hull blasting machine using the vision system to recognize the weld bead. Therefore, we have developed a robot mechanism and drive controller system of the hull blasting robot. And hull blasting characteristics such as the climbing mechanism, vision system, remote controller and CAN have been discussed and compared with the experimental data. The hull blasting robots are able to remove rust or paint at anchor, so the re-docking is unnecessary. Therefore, this can save time and cost of undergoing re-docking process and build more vessels instead. The robot uses sensors to navigate safely around the hull and has a filter system to collect the fouling removed. We have completed a pilot test of the robot and demonstrated the drive control and CAN communication performance.
