Short summary
Our work mainly focuses on the dynamic modeling of a piezoelectric actuator (PA) in the impact drive mechanism in the case of the in-pipe inspection application. The novel model we have developed is able to capture the inertia of the PA and the feature of this model is its computational efficiency with reasonable accuracy. This study has concluded that the inertia of the PA in such a robot can significantly affect the accuracy of the entire model of IDM.
