Abstract
A novel gripper based on magnetostriction phenomena is proposed in this study. The gripper is formed of two parallel cantilever beams each composed of a steel layer laminated by Metglas (2605SC) as the magnetostrictive material. The main advantage of the proposed gripper over the pioneer ones is its remote controllability. Once the gripper is subjected to a magnetic field with appropriate amplitude, the Metglas 2605SC undergoes mechanical strain and as a result, the cantilever beams bend toward each other and accordingly contact takes place between the cantilevers and the object in-between. The motion equation is derived and the reduced order model is obtained by means of Galerkin technique. The effects of the intensity of the magnetic field, as well as the damping effect on the temporal response of the gripper, are studied and reported as well.
