표준공종 분류체계에 따른 국내외 건설 로봇 동향 연구

This study surveys the construction robots developed for the past twenty years through literature review and web search. In these two decades, many studies have been conducted in construction automation, and recently, three-dimensional (3D) printing and unmanned aerial vehicles (UAVs) have become new trends. We collected and analyzed 54 cases conducted in the last twenty years in order to technology and development trends. We classified the construction robot research according to the standard construction work classification. In addition, we evaluated development level through comprehensive of four levels: research stage, research completion stage, practical application stage, and commercialization stage. The analyzed results show that only a few projects succeed in commercialization or practical application limited to only three work categories. Eight counts of earth excavators, four counts of reinforced concrete construction, and four counts of steel structure construction work. Moreover, all research cases, which we collected, focused only on the development of the individual robots. In conclusion, the requirements for the development of integrated control systems or coordination systems are encouraged to automation research in terms of leading successful cases.
