The trend of using modern technologies in the construction industry has been growing stronger recently, particularly in the fields of additive construction or robotic bricklaying. Therefore, specifically for the purpose of robotic bricklaying, we created a digital layout plan for robotic construction works. This video presents a universal methodology for creating a bricklaying plan for various variations of wall building systems. The method is based on the conversion of drawings from the BIM (Building Information Model) environment to the BREP (Boundary Representation) model through use of the IFC (Industry Foundation Classes) format, which simultaneously divides object models into layers and connects discontinuous wall axes by means of an orthogonal arrangement and inserting details into critical structural points. Among other aspects, the developed algorithm proposes the optimal placement of the robotic system inside objects under construction, in order to minimize the distance of the robot’s movement and to reduce its electricity consumption. Digital layout plans created in this way are expected to serve as a stepping stone for robotic bricklaying.
In this video, a method was developed to create a digital bricklaying layout plan for robotic building constructions. This method is based on the conversion of drawings from the BIM environment to a BREP model by means of the IFC format, which simultaneously divides the object model into layers and connects discontinuous wall axes by means of orthogonal arrangement and inserting details into critical structural points. The output of this method is a graphical model, which contains detailed information about each element of the brickwork in the building. The information collected about the elements includes their exact position in the structure, links between the elements, and their material and physical properties. The mathematical model also allows for the generation of outputs from the interface of industrial robots (e.g., KUKA using the KRL code standard). In addition, owing to an extensive database compiled for the purposes of this method, it is possible to determine the total cost and construction time of the object in question, when built by an industrial robot. The proposed method is very versatile, thanks to the extensive database of building elements, and significantly simplifies the use of robots for laying bricks. Even if this method is not used for building operations using industrial robots, it is still very beneficial in the construction industry; for instance, to calculate the number of building elements for suppliers of building materials or, vice versa, in optimizing the amount of building elements ordered from suppliers. Further research will focus on these shortcomings; namely, expanding and improving the database of building elements, creating a similar system for additive construction and other building processes, and reducing the associated electricity consumption by robotic construction systems, in order to satisfy environmental protection.
