Different Kinematic Path Following Controllers for a Wheeled Mobile Robot of (2,0) Type

In the paper a comparative study of selected kinematic path following controllers for a wheeled mobile robot of (2,0) type has been presented. The control strategies are based on one of two approaches to the path parameterization—either the Serret-Frenet frame with an orthogonal projection or the Serret-Frenet frame with a non-orthogonal projection of a robot on the desired path. The complete control system for the wheeled mobile robot consists of two parts, a kinematic controller and a dynamic controller, because of a presence of nonholonomic constraints. The behaviour of the presented algorithms is demonstrated through computer simulations.
