Interactive Parametric Design and Robotic Fabrication within Mixed Reality Environment

In this study, a method, in which parametric design and robotic fabrication are combined into one unified framework, and integrated within a mixed reality environment, where designers can interact with design and fabrication alternatives, and manage this process in collaboration with other designers, is proposed. To achieve this goal, the digital twin of both design and robotic fabrication steps was created within a mixed-reality environment. The proposed method was tested on a design product, which was defined with the shape-grammar method using parametric-modeling tools. In this framework, designers can interact with both design and robotic-fabrication parameters, and subsequent steps are generated instantly. Robotic fabrication can continue uninterrupted with human–robot collaboration. This study contributes to improving design and fabrication possibilities such as mass-customization, and shortens the process from design to production. The user experience and augmented spatial feedback provided by mixed reality are richer than the interaction with the computer screen. Since the whole process from parametric design to robotic fabrication can be controlled by parameters with hand gestures, the perception of reality is richer. The digital twin of parametric design and robotic fabrication is superimposed as holographic content by adding it on top of real-world images. Designers can interact with both design and fabrication processes both physically and virtually and can collaborate with other designers.
