This paper presents the cumulative analysis of the different research work regarding the design and modeling of compliant mechanisms for multi DOF. Several prototypes have been manufactured by different authors with proper design, modeling and evaluate its performance through numerical tool or investigate using experimental results. While considering the sliding mode fuzzy disturbance observer (SMFDO) controller, it is very well used for robustness and for tracking performance. Unfortunately relying completely on the flexures or the compliant mechanism is difficult if and only if we require deep knowledge to design and analysis of these parts. Using the appropriate multi-objective genetic algorithm; it's been observed that the design optimization of the mechanism is achieved. In different applications like compliant diaphragm; using the topology optimization approach the problems have been solved and increase the efficiency of the application. Mechanisms like force amplification, mechanical and geometrical advantage; this topology optimization method is best suited. The topology optimization method is one of the popular and general methods for design and develops the application which works on the survival of the fittest strategy. Thereafter validate the results with experimentation and compare them with analytical results. In some of the cases, the combination of static and dynamics for a large class serial-parallel configuration approach is implemented. All these types of compliant mechanisms have the mobility to transform or transmit the force, motion, energy to undergo an elastic deformation without any joints or links. Among all the research work a cumulative conclusion, as well as the future scope for the compliant mechanism for precision applications has been generated which discussed at the end of the paper.
