A novel five-bar mechanism driven by a cam mechanism

In industry, the four-bar mechanism is popularly applied in the trajectory generation. Different types of trajectories are generated by the chosen of the ratio of links. However, the five-bar mechanism is more flexible to generate a specific path due to it has two degrees of freedom. The geared five-bar mechanism is then commonly used by reducing the degree of freedom of the mechanism into one by implied one pair of gear. In this study, a novel cam driven five-bar mechanism is proposed. It simplifies the feature of the mechanism and improves the possibility of the geared five-bar mechanism for the path generation.
