A path planning method for mobile robot based on artificial potential field

The artificial potential field method is a simple and efficient method used in robot path programming.The improved potential field function method couldn′t solve the local minimum problem.An adding extra control force method is proposed.In this method when repulsive force and attractive force on are the same straight-line,extra control force depending on obstacle is applied on mobile robot which can make it out of local minimum.The simulation result proves the efficient of this method.
