"Sliding mode control of a mobile robot for dynamic obstacle\r\navoidance based on a time-varying harmonic potential field"^^ . "In this paper, a harmonic potential field method for dynamic environments is proposed to generate an on-line reference trajectory for a wheeled mobile robot. A sliding mode controller is used to make the robot move along the prescribed trajectory determined by the gradient lines. The potential field is modified on-line, in order to make the robot avoid the collision with obstacles which move along non a-priori known trajectories with time-varying speed. The mechanism through which the field is modified is based on the so-called ‘collision cone’ concept."^^ . "2007-04-14" . . . . . . . . . . "Antonella"^^ . "Ferrara"^^ . "Antonella Ferrara"^^ . .
