Robot-Controlled Fabrication of Sprayed Concrete Elements as a Cyber-Physical-System

Abstract

In order to make the mass production of free-formed concrete elements for architectural and engineering projects possible and financially achievable new ways of production has to be developed. This paper presents a robot-controlled fabrication of sprayed concrete elements as a cyber-physical-system. It utilizes the concept of Industry 4.0 and IoT-technology together with automatized fabrication methods and developed sophisticated software solutions for communication, planning, modeling and analyzing. This concept bases on a decentralized system of fabrication, analytic and path-planning services connected with a mqtt-communication protocol. Next to the system- and software development a special material based on concrete is developed, shotcrete, which is adapted to needs for the application of spraying.
