Survey on Gait Control Strategies for Biped Robot

As humanoid robots shift from research lab to human living environment, biped robots play a more important role in recent research Peoples are attracted by biped robots for the difficulties in gait control since their dynamic equations are high-order highly-coupled and nonlinear This paper presented the basic concepts in biped gait and major research methods in the filed of biped gait optimization and control Characters of three major models including inverted pendulum, passive gait model and mass-spring model are thoroughly discussed Advantages and disadvantages of all these three models are exhibited by comparison Followed with it, the two kinds of usually used constraints, stability criterion and energy constraint are introduced with abundant examples For stability criterion, zero moment point (ZMP) criterion as the most useful constraints in biped gait generation research is emphasized Finally three intelligent control methods (neuron network, fuzzy logic and genetic algorithm) with their combination methods (fuzzy neuron network, genetic neuron network and so on) were introduced at the end of this paper
