Abstract: The influence of regularly distributed disk-like obstacles on the motion of self propelled particles is investigated within the framework of the Vicsek model. We focus on the systems with large number of self propelled particles that form ordered structures such as traveling bands. The obstacles are arranged in a square lattice. We investigate the influence of their size and their separation on the formation and stability of ordered patterns of moving particles. We have discovered new structures stabilized by different arrangements of obstacles.
