    "abstract": "In two papers we proposed a continuum model for the dynamics of systems of\nself propelling particles with kinematic constraints on the velocities and\ndiscussed some of its properties. The model aims to be analogous to a discrete\nalgorithm used in works by T. Vicsek et al. In this paper we derive the\ncontinuous hydrodynamic model from the discrete description. The similarities\nand differences between the resulting model and the hydrodynamic model\npostulated in our previous papers are discussed. The results clarify the\nassumptions used to obtain a continuous description.",
