Describing the Effective Parameters in Grippers, and Designing the Novel Micro-Nano Gripper

In this paper the effective performance parameters of micro-nano grippers like material specifications, displacement amplification factor, jaws motion characteristic, aspect ratio, micro actuators specification, number of degrees of freedom and so on are attained and studied. These operation indexes can be used for designing the new optimized micro-nano grippers. Using these operation indexes a novel optimized monolithic compliant flexure based micro gripper with significant specification are designed and analyzed using the Finite Element Method (FEM). The presented model has precise manipulation in total micro and nano domain, has large gripping range, the motion of jaws are parallel and simultaneous, the jaw is normally opened, the gripper has good displacement amplification factor and its structure is simple. It can manipulate the object with 1 micrometer diameter up to 1000 micro meter diameter accurately. Finally the operation indexes of the proposed micro gripper are compared with the recent years’ models presented by the researchers.
