In the 1980s, the architecture industry in Japan began investing heavily in robot research in field of building construction. At the time, architecture components were still produced by the modern mindset of mass repetitive manufacturing. As computer-aided drawing (CAD), computer-aided manufacture (CAM), parametric modeling, and internet developed; since 2006 we have seen more and more architecture projects that have taken advantage of robotic arms to build customized designs. Robotic fabrication is most commonly seen in cases that require a specialized design or highly complex usages. The application of the robot arm is greatly depended on the end-effector used by the target workpiece; therefore, we can achieve a machine that takes care of multiple purposes, or a multi-purpose machine. Today, the types of metal processing have gotten increasingly complex to the point where the material must adapt to various kinds of processing equipment. The main subject of study in this digital age is to explore the materiality of metal and use it as the primary material in robotic fabrication. The major phases of this research include a set-up of the architecture foundation for robotic intelligence, robotic offline programming, and robotic fabrication. The layout of the research is as follows: 1. Through literature reviews, establish a common robotic knowledge database while organizing a detailed list of the different types of metal processing procedures. This preliminary set up will allow us to choose the most suitable options for the next phase of the research. 2. By using the robotic arm, individual simulations will be conducted for each type of metal processing listed above. These simulations may include an installation of the processing environment, initial testing as well as advanced operation, all of which will be arranged through a gradual increase in overall difficulty. In addition, a 1:1 scale model will be produced at the completion of the research to confirm the validity of the metal processing. 3. By reviewing the knowledge gained from the metal processing simulation, and then comparing it with traditional metal processing methods, multiple robotic aided manufacturing design processes can be established for later research and development. This research aims to use parametric modelling and offline programming for robotic arms to assist with the metal processing procedure. In addition, each metal processing will undergo its own simulation in order to create a life size model. This finished product will ultimately help create and become the foundation for various applications of the robotic aided manufacturing process. Looking forward to the completion of this research and the impact it will bring for more creative applications of robotic fabrication in architecture. Hope that the results from this study will be a great source of reference and value for future researchers.
