Realization of a high speed biped using modern control theory

Abstract

The purpose of this paper is to propose a new controlling method of the biped locomotion composed of seven links and to show simulated and experimental data of the locomotive motion of the biped called CW-1 built in our laboratory. The control method depends mainly on the linear optimal state feedback regulator, which stabilizes the stance supported by both legs as a commanded attitude. As a result the biped successfully walks any pre-determined steps such that one step takes only one second.
