Micro/nano grip and move compliant mechanism with parallel movement tips

The development and deployment of micro and nano-electro-mechanical systems (MEMS/NEMS) are critical to the economy of each country and society because these technologies will lead to major breakthroughs in information technology and computers, medicine and health, manufacturing and transportation, power and energy systems, and avionics and national security. The assembly of micro-devices involves handling of parts that are extremely very small. This paper presents the design of compliant grip and move manipulators with parallel movement tips. The integration of both gripping and moving manipulators with parallel movement tips is accomplished by the use of compliant mechanisms, which generate paths that are symmetric. The structural topology optimization approach is applied in order to find the optimal material distribution in the proposed domain for compliant mechanism. A 2-D finite element analysis (FEA) model using ANSYS is constructed for the propose design domain. The optimal configurations of the compliant mechanism, which can realize a micro grip and move with parallel movement tips, is demonstrated.
