Digitalisation has found its way into timber construction, with entire elements already being fabricated by computer-aided systems. The raw material is cut to size by the machines, but in most cases it still has to be manually assembled to create a plane frame.
In the past, this fabrication process came with many geometric restrictions. The robot first takes a timber beam and guides it while it is sawed to size. After an automatic tool change, a second robot drills the required holes for connecting the beams. In the final step, the two robots work together and position the beams in the precise spatial arrangement based on the computer layout. To prevent collisions when positioning the individual timber beams, the researchers have developed an algorithm that constantly recalculates the path of motion for the robots according to the current state of construction.
Workers then manually bolt the beams together. Unlike traditional timber frame construction, Spatial Timber Assemblies can manage without reinforcement plates because the required rigidity and load-bearing result from the geometric structure. Not only does this save material; it also opens up new creative possibilities. A total of six spatial, geometrically unique timber modules will be prefabricated in this way for the first time. The robots use information from a computer-aided design model to cut and arrange the timber beams.
This method was specially developed during the project and uses various input parameters to create a geometry consisting of timber beams in total. This kind of integrated digital architecture is closing the gap between design, planning and execution. Kohler believes in the synergy effect brought about by the partnership: Conversely, digitalisation can improve craftsmanship and open up new opportunities.
