Zero Moment Point를 이용한 이족보행로봇의 경사로 걸음새 제어에 관한 연구

Abstract

In this paper, we propose stable walking algorithm using ZMP for the biped robot in the slope-way. At first, we define discrete state variables that classified stable area and unstable area by center of mass from ZMP during slope-way walking. For the stable walking gait, the discrete state controller for determining the high-level and low-level decision making are designed. The high-level decision making is composed of the discrete state variables; left foot support phase, right foot support phase, nat-way, and slope-way. Then the continuous state controller is implemented for the low-level decision making using ZMP.
