The influence of obstacles on collective motion of self-propelled objects
Abstract
We investigate the influence of obstacles on the collective motion of self propelled objects in the framework of the Vicsek model. The obstacles are arranged in a square lattice and have circular shape. We show that by increasing the radius of the obstacles the collective motion of the self propelled object can be altered from super diffusive to diffusive. For obstacles with small radius, the system is composed of large clusters moving in one direction, for larger radius, the system is composed of small clusters moving randomly in different directions.
