Abstract

The layout work of building structures is a task that requires high precision to form the main structure in the correct position. However, layout work is greatly affected by the operator's skill level, and productivity can be reduced due to lack of accuracy, detection limits, information loss, and errors. To solve these problems, automation of the entire layout work and introduction of information technology are necessary. For this purpose, automation of layout work using construction robots can be an effective means of doing this. Accordingly, the need for automated layout has been recognized at home and abroad, and related technology development has been continuously carried out. However, most automated equipment has limitations when operating in an building structures environment, as it is performed on buildings with finished floors to ensure precision. Accordingly, in this study, we developed a prototype of an automated layout robot that operates for building structures environment. The developed robot largely consists of a driving part, a marking part, a sensing part, and a control part, and was designed considering the layout work environment.Driving performance was satisfactory, but there were some errors, and marking performance was accurate, but marking quality was disappointing. The sensing unit and control unit operated normally, and the need for improvement in some driving methods and marking quality was confirmed. This study can be applied to domestic construction sites to improve layout work accuracy, quality uniformity, and work productivity, We increase the efficiency of inspection by digitizing layout work process information. In addition, the economic feasibility of automated robots was analyzed based on the results of a comparative analysis of productivity between conventional and automated methods. If the automated layout robot developed through this study is put into practical use, possible problems that may arise in layout work can be resolved. It is expected that it will also be possible to reduce work input costs by improving work productivity and ensuring uniformity of quality.
