The present invention relates to a mobile robot and moving the robot path generation method having the same movement path generation device of the robot, the path generation method of the mobile robot, and receiving the environment map of obstacles including step, said obstacle delete of the obstacles or less than the safety of the first specific criteria for the mobile robot and generating a route between a starting point and a target point, recovering the removed obstacles and the safety for the recovered obstacle along the travel path If the safety of the steps to scan, and the recovered obstacle or less than the second specific criteria to generate the route points between the starting point and a target point comprises the step of changing the moving path using the route points. In this way the invention provides a programming path of the mobile robot for generating a moving path for the mobile robot to more robust. ;
