Design and Analysis of Compliant Macro Scale Gripper

At the present day, there is a need of creative and innovative designs. Compliant mechanisms have a huge contribution in the mechanical engineering field and become an important branch of modern mechanisms. Complaint macro grippers need to be precise, accurate, and automated in the field of medical, robotics, material science, and in the automotive industry for gripping, handling, and assembling of objects. A compliant mechanism offers a better and a precise solution. Flexure-based compliant mechanisms has various application in medical, robotics, MEMS, biomedical devices, aerospace industry, adaptive structures, and automotive industry for gripping handling and manipulation purpose. due to the excellent benefits of no friction, no backlash, no wear, and the least requirement of assembly. By applying Pseudo Rigid Body Model (PRBM) the compliant macro scale gripper is developed. The result obtained by PRBM model is verified by simulation. ANSYS software is used for analysis and simulation. This paper represents a study of flexure-based compliant mechanisms.
