By invoking the principle of minimum potential energy, and the Gauss principle of least constraint, it is shown that the quasi-static and dynamic evolution of these robots, are solutions of optimal control problems (OCPs) in the space variable, which can be solved at each step (of loading or time) of a simulation with the shooting method. In addition to offering an alternative viewpoint on several simulation approaches proposed in the recent past, the optimal control viewpoint \fred{allows us to improve some of them while providing a better understanding of their numerical properties}. The approach and its properties are illustrated through a set of numerical examples validated against a reference simulator.Show less >
