3. A reference example of mechanism is given as shown in Fig. 1. Students are required to design a feasible mechanism by themselves, draw its kinematic diagram, mark the positions and number of moving components, driving link, revolute pairs, prismatic pairs, low pairs, high pairs, compound hinge, redundant constraints, passive DOF, and calculate the degrees of freedom. Disassemble Assur-Groups of the mechanism, and draw the diagram of assur-groups of the disassembled mechanism. According to the disassembled assur-groups, arrange the assur-groups in different orders. What are the possible mechanism motion schemes? It is required to draw the kinematic diagrams of those mechanisms, and to compare the motion transmission schemes.
