Abstract
Disclosed is an underwater robot based on flapping comprising: an actuator including a smart material and directional material, wherein the smart material is changed in its shape according to an external signal, and the directional material restricts a deformation in a specific direction; a body connected with the actuator; and a controller which makes the actuator perform a first stroke in a direction, and a second stroke in another direction being different from that of the first stroke; wherein the actuator performs at least one deformation of bending and twisting according to position of the smart material and directionality of the directional material, and furthermore enables to simultaneously perform the smooth bending and twisting motion with the simple structure by adjusting the position of the smart material functioning as the active component, and the directionality of the directional material functioning as the passive component.
