Abstract

This article studies the design and analysis of a new large-scale high precision compact gripper to achieve damage-avoiding capture using compliant mechanism. The gripper is constructed using flexure hinges and it is actuated by only one piezoelectric stack actuator (PSA). The compact damage-avoiding gripper [CDAG] is consisted of compact two-stage amplifier module and constant force mechanism module. The effect of constant force structure module is realized by integrating the positive stiffness beam with the negative stiffness beam. The compact two-stage amplifier is composed of two classical bridge amplifier in series so as to augment the ratio of amplification. The gripper will be analyzed by Finite-element analysis software to simulate its function.
