This paper presents a comprehensive study on the workspace of a continuum manipulator using a universal joint. The research focuses on analyzing the effect of different parameters such as joint angles and flexible link lengths on the workspace of the manipulator. A mathematical model is developed to determine the workspace and validate the results through simulations. The study also includes a discussion on the limitations and challenges of using a universal joint in continuum manipulators and ways to overcome them. The findings of this research contribute to the understanding of the workspace of continuum manipulators and can be used to design more effective and efficient manipulator systems.
