Collaborative Robotics in Construction: A Test Case on Screwing Gypsum Boards on Ceiling

Abstract

The use of collaborative robots (cobots) and human robot collaboration has started to increase in diverse industrial areas in the past years. However, cobots are seldom applied in construction work even if there is a growing need for robotics solutions in this area. This study aims to present the possibilities of applying lightweight cobots for single tasks in the construction sector. This paper presents the development of a proof-of-concept dedicated to screwing gypsum board panels to the ceiling of a room. After identifying the challenges related to this task, we present the cobot solution that we implemented for this purpose. Our results show that repetitive screwing work in upright position achieved by cobot can benefit workers by removing ergonomical strain. At the same time, cobot ensures that this task is achieved with constant performance. Future research directions lead to the search for better accuracy in screw positioning and more dynamic ways of collaboration with human workers.
