Timber Assembly with Distributed Architectural Robotics, 2018-2022
PhD Forschungsprojekt
This PhD research focuses on the robotic assembly of timber structures with integral timber joints, specifically, crossed-half-lap joints. The proposed method uses a set of custom-built, remote-controlled, high-force robotic clamps to operate in collaboration with an industrial robotic arm to overcome challenges of timber joint assembly, such as providing large assembly forces and overcoming misalignments. This method enables the automatic assembly of non-repetitive and spatially connected timber structures.
To aid the design of structures that can be constructed with this fabrication method, we developed custom computer modeling, visualization, and feasibility-checking software for designing structures with lap joints. In addition, we also used state-of-the-art software for (1) Online robotic control, for synchronizing arm and clamps (2) Robotic path planning among dense partially-built structures. (3) Structural analysis of the completed timber structure. We developed custom software for modeling, visualization, and feasibility-checking
As a proof of concept, we have designed and robotically assembled a spatial frame structure (4.8 x 3.0m footprint, 3.4m tall) at the Robotic Fabrication Lab, ETH Zurich comprising 40 pieces of 100x100mm profile timber elements. We used a 6-axis robotic arm mounted on a 3-axis overhead gantry and four custom robotic clamps for the assembly.
