Abstract:

Robot path planning under dynamic and unknown environment is one of important issues in mobile robot navigation, which is difficult to deal with by traditional methods. Aiming at this problem, an improved hybrid path planning algorithm is proposed. In the proposed approach, an improved Memetic algorithm is used to obtain an optimal global path at first, which is used to navigate the robot. And then a Morphin algorithm is used to plan an optimal local path based on the information sensed to avoid dynamic obstacles. The simulation experiments results show that the proposed algorithm is of good efficiency in the path planning task under dynamic and unknown environment.
