Wood working robots
We return to the world of architecture with robotic technology, but this time, aimed at executing and assembling wooden structures. Although already in the article on how to design a wooden structure with robots we could see that they are experienced in projecting and cutting parts of a project with almost perfect optimization. Now we have to see how they are able to work on the assembly of wooden frames. Carpenter, you already have help!
Digitization has found its way into wood construction, we know that entire components are already manufactured with computer aided systems. Although the raw material is cut by machines, it is usually installed manually to form the structure. Until now, this manufacturing process has severely restricted the geometric freedom of a design in many cases.
As part of the National Center of Competence (Digital Fabrication), researchers at the Chair for Digital Architecture and Fabrication (ETH Zurich) have developed a new digital method to improve wood construction and make it more efficient and easier.
Let us remember that they are the same ones who designed the robot that assembles reinforced steel structures for construction in a short time.
The Spatial Timber Assemblies project results in using multiple robots to design, manufacture and assemble wooden frames without human contact. It expands the possibilities of traditional construction in wooden structures by allowing the efficient execution of geometrically complex wooden modules and in an easier way.
Robotic precision has arrived! … “The system begins with predicting the load of a beam and designing its dimensions by computer according to project specifications. Subsequently, a robot takes a wooden beam and feeds it before a saw to cut it. Then a second robot pre-drills the holes required for the connections to the beams. Finally, the two robots cooperate in symbiosis and arrange the beams precisely according to the computer design. "
To avoid collisions when positioning individual wooden beams, the researchers have developed an algorithm that continually recalculates the path of motion based on construction progress. Next, the craftsmen have to manually screw in the rafters.
Unlike traditional construction, the assembly of these wooden structures does not need any element of reinforcement or support since the rigidity is supported by the robotic arms. This not only saves material, but also opens up new perspectives and possibilities in the design of precast elements for houses and new ways of modulating structures.
Although the system is still in the testing phase, we can already sense a not too distant future where carpenters will work side by side with robotics.
