Rhythmic motions of animals, such as walking and running, are generated and controlled by central pattern generator (CPG) in the spinal cord. We focused on swimming as one of rhythmic motions of human, supposing that swimming motion is generated by CPG. We constructed a CPG model with neural oscillators proposed by Matsuoka and generated the motor pattern of arms and legs in the crawl stroke with the model. First, we generated joint trajectories of the legs with outputs from neural oscillators by coordinating the parameters and coupling pattern of the neural oscillators. Next, we generated the motor pattern of the arms which coordinates that of the legs by coupling the neural oscillators of the arms with those of the legs. We confirmed that the generated motor patterns realized the crawl stroke by simulation. It was found that the motor pattern of the arms conceitedly changes according to the change of the cycle of the flutter kick.
