The geometrical configuration of the locust, Oedaleus infernalis, was observed by using the stereomicroscope. The jumping process of the locust was captured by high-speed photography method. The motion morphology of the locust during jumping was analyzed and the jumping parameters were gained. The technology of virtual prototype was used to establish the kinematics model of the locust-like robot. Combined with the 3D dynamic simulation, displacement, velocity, acceleration, force and moment of the locust-like robot during jumping were analyzed. The characteristics of the locust-like robot during jumping were discussed. The optimum structural parameters of the virtual prototype of the locust-like robot were obtained, and then the data were provided with the physical prototype in structural design.
