This paper describes the design, modeling, and testing of a novel flexure-based microgripper for large jaw displacement with high resolution. Such is indispensable in micro∕nano manipulation. In achieving displacement, double amplification mechanisms, namely, Scott-Russell mechanism leverage arranged series, are utilized to overcome limited output microgrippers driven by piezoelectric actuators. The mechanical performance analyzed using pseudo rigid body model approach. Finite element...
Abstract Precise grasping using compliant grippers is a crucial step in many micro/nano manipulations, which require to exhibit excellent static and dynamic performances. This paper presents novel piezoelectric-driven gripper with position force sensing. A series structure that combines differential amplification mechanism Scott-Russell introduced enhance the stroke. To ensure linear motion of jaws, series-parallel hybrid parallelogram employed. Analytical models for ratio, input stiffness,...
