Quadruped robots are often in the state of dynamically stable. But in certain extreme circumstances, static stability is required in the locomotion of quadruped robots. Based on the DST(Double-Support Triangle) theory, this paper designed two kinds of COG(Center of Gravity) and swing leg tip trajectories with crawl gait, and proposed an optimized crawl gait using ZMP(Zero-Moment Point) stability criterion. The design and crawl gait planning ensures the static stability in quadruped robots' locomotion, and it's validated in Matlab and RecurDyn environment.
