Abstract
The structural features of a system deeply affect on the attribute of the system and the function. The effect of the phenomenon can be found in wide area, such as animal brain and WWW. In this paper, we deal with a method for changing a behavior of a system by structural modification by using coupled van der Pol(VDP) oscillators. At first, we analyze mathematically a simple oscillator network composed of 4 oscillators. Secondly, according to the analysis result, we describe some characteristic between the structural features of the network and the convergent states. Finally, we propose a method for changing behavior, and apply the method to a hexapod robot.
