On-Site Robotics for Sustainable Construction
Although additive and robotic manufacturing, is considered a technology with lots of potentials in the construction industry, its deployment has not yet reached wide applications for on site construction of sustainable architectural structures. This paper focuses on the deployment of a 3D printing technology that combines robotics with natural materials for the construction of environmentally performing small scale buildings. Cable robots are explored for 3D printing with adobe, while drones are explored for real-time monitoring technologies of the construction process. A full scale prototype of the technology has been deployed during 15 days at an international construction fair, demonstrating its potential by producing live a 20 m2 pavilion. The paper describes and discusses the experience, feasibility and limitations of the technology operating on site and in a direct collaboration with human operators and craftsmen. The prototype demonstration presented in the paper has led to the conclusion that there is a significant potential of using the technology for large scale sustainable architectural constructions on-site.
