In this paper, the authors described the modeling method of the instantaneous force generation mechanism inspired by the striking motion of Odontodactylus scyllarus and the evaluation of the mechanism. Animals use the contraction of living muscle as actuators to perform various movements. Some arthropods produce instantaneous movements by using the combined force of the exoskeleton spring and muscle force. Few reports deal with such an instantaneous force generation mechanism of the combined force in the numerical simulation. Our purpose of this study was to construct the instantaneous force generation mechanism by the combined force of elastic elements of the exoskeleton and pneumatic artificial muscles, inspired by the instantaneous force generation mechanism of Odontodactylus scyllarus. In the previous study, we have confirmed that the instantaneous force generation device and the possibility of generating instantaneous force by the physical model. In this paper, the authors further constructed a model of the proposed mechanism as a translational rotation system and performed a dynamic analysis by numerical simulation, confirming the effectiveness of the proposed model.
