Development of on-site robotic system for timber construction using vertical movement method
Type: dissertation
Abstract: This dissertation develops and validates an integrated robotic construction framework for Layered Interlaced Timber Arch-Shells (LITAS), combining parametric design, robotic path planning, multi-functional end-effector development, and construction-phase life cycle assessment. The research addresses key barriers to robotic timber construction, including limited workspace, insufficient fastening automation, and the lack of quantitative environmental evidence. Two robotic systems—a stationary system and a vertically mobile system—were developed and experimentally validated for automated screw-fastened timber assembly. A construction-phase LCA framework was then established using IPCC 2021 and ReCiPe 2016 methods to quantify environmental impacts with component-level resolution. Results show that the vertically mobile system enables continuous assembly with acceptable accuracy, while construction-phase impacts are dominated by timber and screw production rather than robotic energy use. Finally, a simulation-based large-scale scenario demonstrates the scalability of the proposed workflow toward architectural applications, supporting low-carbon and intelligent timber construction.
