Down through the years, human needs and desires have required a robot system to work at hazardous environments instead. Current painting task is costly and laborious, and it exposes workers to significant health and safety risks. Automation system offers potential improvement in this area and is especially well suited to the outer-wall painting tasks in concrete structures. This paper introduces the result of gondola-type building management robot(G-BMR) platform and mechanism for moving/tasking on building outer-wall for the outer-wall painting. Its technical and economic feasibility are conducted, and it is concluded that developing G-BMR is physically and economically feasible in this research. And we discuss about the future of G-BMR and automation in construction field.

With recent growth of the economy and development of construction technology, the increase of high-rise buildings is appearing rapidly in urban areas. For this reason, the interest in building maintenance has also been increasing. However, it has many safety problems because it is difficult for the workers to access the exterior wall of building. Therefore, the maintenance system of high-rise building stands out as being important issues to be developed, so that a variety of robot systems have been developed to accomplish the building-wall maintenance works. In this paper, the maintenance robots are classified in painting, inspecting, cleaning systems according to the maintenance works. Then, their locomotion and adhesion mechanisms are analyzed including their applicability to the real maintenance works. This study can be used to develop maintenance robotic system that is more efficient and stable than existing ones.

본 논문은 선박의 외벽 청소를 위하여 영상기반의 용접부 인식기능을 탑재한 선체 블라시팅 로봇을 제시하였다. 본 로봇제작의 목표로서 선체 청소로봇의 설계 및 제작과정과 영상을 이용한 용접 비드 인식에 따른 성능 결과를 제시하였다. 그리고, 로봇제작에 따른 메카니즘과 로봇시스템의 제어기 제작 과정과 수직상승 메카니즘, 영상 시스템, 원격제어 기능을 갖는 선체 청소 특성에 대해서 기술하였다. 이러한 선체 청소로봇은 선박이 정박하는 동안에 청소를 수행하게 되므로 재도킹을 할 필요가 없는 장점이 있다. 따라서, 개발된 청소작업은 시간과 비용을 절감할 수 있고, 선체의 수직벽면의 주행이 가능하므로 부유물질 등을 수집할 수 있는 필러장치를 장착하고 있다. 개발된 로봇시스템의 동작 및 통신 성능테스트 결과를 통하여 성능평가 결과를 제시하였다.
