Collective motion of interacting simple robots

Many livings such as fish and birds form groups which we consider as collective systems. The collective motion of the group shows various dynamics and patterns, and many model equations are proposed to explain such phenomenon. In our previous paper, we proposed simple deterministic model which shows various types of group behaviors. In this paper, we modified our model from the viewpoint of real robotic system. We assumed that the space resolution of each robot's sensors is low and that the sensors detect the nearest robots. We examined their performance by computer simulation and confirmed the robots with modified model also shows various types of motion. We also applied this system to foraging task and showed its performance.
