Special standards are necessary regarding the drive and motion system in precision engineering, biomechanics application, micro-electro mechanical system (MEMS), nanotechnology application. With the help of conventional rigid body mechanism, backlash problem becomes a more dominant problem in designing a high precision positioning stage with micro–scale (micrometer or nanometer) resolution. Compliant mechanisms are found to be more convenient over rigid body mechanisms. A compliant mechanism is a mechanical device in which elastic deformation is used to achieve force and motion transmission. Compliant mechanism provides a jointless mechanism eliminating issues regarding wear, lubrication, backlash, assembly. The use of compliant mechanism in linear displacement application is investigated in this research. The topology for the mechanism is optimized and the total deformation is calculated with ANSYS software. The software results are checked by performing actual experimentation. Therefore compliant retractor mechanism is very well suited for positioning by scale up the motion of linear stage and topology optimization, analyze and test a compliant retractor mechanism.
