[AR]OBOT tries to assist the robotic fabrication process for parametric architectural structures with Augmented Reality (AR) technology to explore new possibilities for easy architectural robotic operations. Due to the lack of computer programming skills and the disconnection between design and fabrication, architects are hampered in the robotic operation process. As part of our project, we create a visualization prototype in which robotic and on-site related information is being shown through AR devices overlapping on the physical world; followed by a robotic trajectory planning method in which designers’ gestures are being identified by AR as location nodes and calculated with the obstacle avoidance system; and an operation process in which robots are being controlled by human gestures and interactions with holographic simulation to enhance the robotic fabrication process efficiency and safety. In this paper, we share the preliminary results to demonstrate a new kind of AR-assisted workflow for the architects to perform the robotic fabrication of parametric architectural structures intuitively.
