Abstract:Toaddressthe limitation of single-mode motion in micro piezoelectric robots,this study proposes apiezoelectric-drivenmicro amphibious crawling robot.Therobotutilizes the inverse piezoelectric efectof piezoelectricceramics to excite multiple vibration modes of its body,enabling bothterestrial crawlingviacontact frictionand aquatic swimming via jet flow,thus achieving amphibious locomotion.A compact structure driven bya single-phase excitation signal alows dual-mode motionon land and in water.Finite element modeling wasconducted using Ansys l9.0 to analyze the robot'sstructural design,operating principle,and optimal working modes.Aprototype was fabricated and experimentally tested.At a driving frequency of 17.0kHz and a peak -to-peak voltage of 100V ,therobot achieved a maximum crawling speed of 130mm/s ,equivalent to 6.5 body lengthsper second.At 227.0kHz and the same voltage,its average swimming speed on the water surface reached 50mm/s ,or 2.5 body lengths per second. The consistency between simulationandexperimentalresultsverifiesthe feasibilityof theproposed structural designand confirms the validity of the operating principle.
