In this study, modular design for compliant stage using a parallelogram flexure module is proposed. The material of the proposed stages chosen is Aluminium alloy T6-6051 due to excellent phase stability, low internal stresses, low density etc. The stage is driven by a linear electromagnetic actuator i.e. voice coil actuator. The preliminary static structural analysis is used to determine the range of motion, stiffness by considering stress limitations. FEA results show a maximum range of motion up to 30mm without exceeding stress limit of 275 Mpa. The proposed mechanisms provide low stiffness in the degree of freedom directions and provide large stiffness in the degree of constraint direction.so it is adequately constrained. The stage provides high precision and repeatability with an increased range of motion, minimal parasitic motions (i.e.150 microns) and limited cross axes coupling.

Meso Scale

Mechanisms with dexterous manipulation capabilities are needed for many applications at the meso scale (1–5 mm diameter with micro scale features). Scaling down larger designs has proven to be impossible in many cases, and the manipulation forces produced by most existing meso scale designs are notably insufficient for intended applications. A review of articulating mechanisms and manipulator technologies developed within the last decade is presented, and the potential for these technologies to be implemented at the meso scale is explored. The utility of these systems is analyzed in terms of two main performance metrics: maximum range of motion and force application. Determining the miniaturization potential and performance capabilities of these mechanisms has highlighted necessary improvements for current systems and provided insight on which system types are most likely to be effective on the meso scale.
