Abstract :
It is well known that locomotion rhythms of living organisms are generated by CPG (central pattern generator). In this paper, we discuss the synchronization phenomena and oscillation patterns of the coupled oscillators system using pulse-type hardware neuron models (P-HNMs) for the purpose of constructing the CPG model. It is shown that the plural coupled P-HNMs connected by excitatory-inhibitory mutual coupling can generate various oscillation patterns. Therefore, we construct the CPG model by using the coupled P-HNMs to generate several locomotion rhythms. As a result, we show clearly that the IC chip of CPG model, which can generate the quadruped locomotion patterns, can be constructed by CMOS process.
