The presented work is practical and valuable because it shows the most responsible mechanism for obtaining the minimum effort to swing the pendulum as well as provides a methodology that guarantees relatively fast and long-lasting oscillations, as stated in the problem definition below. First, the three-dimensional model is introduced. Next, the components are listed, stating the functions of each part of the system. Finally, the system’s working principle is supported by mathematical modeling, results of numerical simulations covered by essential conclusions
