Process Analysis of Cable-Driven Parallel Robots for Automated Construction

This contribution presents an introduction to cable robots, their properties and their mechatronic design for application in automated construction. Today, most steps involved in the construction process are performed manually. Thus, the integration of automated functions demands a closer look at the production and logistic paradigms, these are the main focus of this paper. Based on case studies, the authors discuss upcoming transformations in shell production by comparing the conventional construction process with proposed processes involving cable-driven parallel robots. The focus is on bricklaying and working methods for the installation of prefabricated elements. Adaptations to site logistics and changes in work organization are also considered. A case study and sensitivity analysis based on system dynamics modeling are introduced, and the conceptual design of an experimental prototype is presented. The results of the investigations show that the use of a cable-driven robot is feasible for onsite construction, enabling automation of processes to save time and cost. The study investigates crucial parameters and the potential for cable robots in the field of construction.
