The path planning of mobile robot is an important issue in the field of robotics. Many algorithms have been designed to solve the path planning problem, including classical as well as intelligent approaches. The main aim of path planning is to construct collision free path a specified start position to the target position.-The path planning of mobile robot is an important issue in the field of robotics.
