For the controllable periodic gait of dynamic walking bipedal robots, properties such as stabilities, robustness and optimal control strategies, and research status and development trend at home and abroad are explored in this paper.First of all, we introduce the dynamics mathematical model of the dynamic biped robot and present locomotion gait and control system theory for the dynamic walking bipedal robots. Secondly, we discuss the current research methods of controllable periodic gait stability for the dynamic walking bipedal robots and analyze the shortcomings of these methods;we also describe the controllable gait cycle optimization control strategy and illuminate both advantages and disadvantages of various strategies. Finally, we present challenges and future works for the dynamic biped robot research areas and give the idea of robust stability and the controllable gait cycle.
