Research on an inertial piezoelectric actuator for a micro in-pipe robot

In general, a micro robot system includes a microactuator, micro sensor, energy supply, and control sys-tem. At present, the research on a micro actuator inChina is basal in a laboratory phase, which lacks astrict analysis in theory. Hence, it should first besolved for the design on a micro actuator or micro robotthat the drive principiumof micro actuator is researchedand the dynamical equation is established. In this pa-per, a newkind of inertial piezoelectric actuator is pro-posed. The driv…
