Abstract
Topology optimization (TO) is a practical design algorithm to create novel and efficient structures. However, the design resulting from TO often has a complex geometry. It brings about a considerable challenge for manufacturing and construction. This research aims to propose a construction workflow that builds TO structures by fabricating wooden sticks automatically. In the workflow, the branches of an optimal structure are firstly simplified by skeletonization. Then, a developed program creates the automatic cutting paths of interlocking joints according to the angle between two adjacent skeletons. Finally, the generated paths can be sent to a robotic arm to fabricate sticks. This study shows the potential of building a TO structure using automatic devices and interlocking joints. To verify the proposed work, 758 different wooden sticks are manufactured to assemble a topologically optimized wooden bridge (8.5m×3.3m×2.0m).
