A Swarm Robotic System consists of many small units (agents) which have decision and action options. The system behavior results from the behavior of the individual agents and is not controlled by a higher-level system. This will be examined in the context of my diploma thesis based on changeable, self-organizing architecture. Here spider-like robots (agents) develop a structure of fibers, which they produce themselves. The resulting structures can be redesigned or even dismantled to meet new requirements. The agents represent the „construction worker of the future“. A special focus is on sustainability. Analogous to the term urban mining takes place here the material extraction in the form of a „waste mining“. The agents are exposed on polluted beaches, collect, and sort the washed-up garbage. From the recyclable plastic printable filament is then generated. After a kind of need pyramid, they then develop structures that initially range from the sorting of trash (baskets) to architecture that can be used by humans and animals. The aim of the diploma thesis is a simulation of the development process and the visualization of the generated architectural structures by means of 3D printing as well as the construction of a prototype.
