Wigwam pavilion project was a continuation of the design studio course-work in 4th year of undergraduate studies at Feng Chia University in Taichung City, Taiwan. Team of two students (Annie LOKE and Eric CHEN) developed the algorithm for agent based behavior model. The design was further developed (by Ana ILIC and Che Wei LIN) for the purpose of the pavilion research project in collaboration with Feng Chia University and WINSON Machinery Co., LTD in Lugang, Taiwan who provided their facilities and KUKA robotic arm for the duration of the project. Taking place over the course of 1 year, project established and overcame problems of material performance, material optimization, fabrication, parametric design, prototyping, and assembly. It is currently on display at the 5F open atrium of The Feng Chia University located next to the famous Feng Chia Night Market.
The pavilion shape had derived from multiple studies of agent based behavior. The form was based on a dome as one of the most stable, self-supported structures. The dome was used as the environment which was set as the boundary in which the agents were acting and interacting. By recording the movement of the agents we were creating traces that are used as a guideline to the final form. From that point the linear elements (recorded agent traces) were converted to three-dimensional "branch-like" elements which were intricately woven together.
Fabrication material was plywood and the main agenda was to assemble the whole structure without use of any metal joints such as nails or nuts and bolts. Therefore, we had to design custom joint system which was based on traditional Japanese carpentry joints.
First stage of fabrication involved CNC cutting. We cut the plywood into custom pieces which we glued together to assemble solid wood-blocks of custom shape corresponding to every individual segment of the overall structure. The challenge was to create a block of smallest volume in order to save the minimize the material waste and time and cost of robotic milling.
Second stage of fabrication was transporting newly created volumes to the factory in Lugang where the robotic milling took place. The engineers of WINSON Machinery Co.,LTD were coordinating and tutoring us on how to operate the robotic milling so we could further on continue the fabrication independently. Engineers of QDesign in Italy were remotely assisting us on how to operate the software they provided for controlling the robotic arm.
Final stage was to transport the pieces back to the site and assemble them together. At the bottom we secured the whole structure with polygonal metal ring which had a function to prevent the structure from flattening to the ground. As the final finish, the structure was painted with wood varnish to protect it from rain and extreme humidity of Taiwan climate.
