Design of a four bar linkage transforming a box with 4 pointaccuracy in comparison of 3 point

In this paper, a mechanism which transfers a box at first from 3 points and then from 4 points is discussedand the answers are compared to each other. Mechanism is designed for 4 points through Burmester theory and also for the 3 point accuracy and it isdesigned by analytical method and also geometrical method.After designing the mechanism, angular velocity, angular acceleration and maximum input torque arestudied.The advantage of Burmester theory is that, instead of unique answer we get a group of answers and wecan select the best choice.The answers of this method are compared through the answers of analyzing the mechanism by SAM6.0software
