The simulation results of walking model Ohgane,Ei,Mahara,2009 the period when , the phase of CPG shifted ahead of body; besides, this phase shift increases in proportion to the increase of

Problem system Van der Pol The mechanism for causing a very stable walking is limit cycle of CPG activity. The study direct toward its confirmation by replacing description of the CPG with other limit cycle oscillators. system Van der Pol
