For the merit of high rotational accuracy, circular flexure hinges are used as revolute joints to connect the moving linkages and the stationary frame. The clamping force profile in the gripper is designed so that the maximum clamping force is generated for the largest object. However, in applications in which there is side loading on the system in a direction transverse to the generated straight line, the Scott Russell mechanism is handicapped since, in this mechanism, the links pass over each other, making it difficult to provide a . Among the more widely used mechanisms of this type is the Scott Russell mechanism. It is evident from the figure that this mechanism is made up of isosceles triangles, AB, AC and AO2 are of equal lengths. the present invention relates to a device applied with a scott russell mechanism where a main arm member and a sub arm member are coupled to each other and a coupling angle therebetween is. One such example is Scott-Russell Mechanism as shown in the figure. Therefore, the Scott-Russell mechanism can be considered as a straight-line amplifying mechanism with a fixed amplification ratio in the case of small-motion applications.
