Abstract

Using a linearized analytical Poincaré map, we analyzed the stability of Passive Dynamic Walking (PDW), focusing on bifurcation phenomenon in PDW. Although it is well-known, bifurcation of the walking period has not been well studied. Based on our previous research, we derive an analytical Poincaré map for 2-period walking to discuss PDW stability of PDW with this map. In addition, we point out that there is a similar interesting structure in this Poincaré map.
