Abstract

This paper deals with the reactive behavior generation for hexapod walking inspired by insects’ robust and dexterous performance in complex environment. The single-leg controller including a coupled CPG network and linear coefficient converter is developed to yield stable and rhythmic signals for joint movement, the limit cycle behavior of which is systematically investigated with the Multi-variable Harmonic Balance (MHB) analysis. With these results, two typical local reflexes are further established. Based on the structure of the proposed single-leg controller, the elevator reflex is fulfilled via orbit attraction of limit cycles while the searching reflex is realized via limit cycle shift. The effectiveness of the proposed algorithm is confirmed through walking simulations.
