Data-Driven Dynamic Modeling of a Tendon-Actuated Continuum Robot

The paper frames the work as model predictive controlControl & PlanningModel Predictive Control (MPC)A control method that repeatedly plans a short future path, acts a little, then replans.. Start here because it defines what success means and which assumptions the rest of the method inherits.
