Special Wide Area Path Planning Method of an Autonomous Mobile Robot Using GPS

Using sensor and GPS to make a trajectory planning for the stationary obstacle,autonomous mobile robot can assume that it is placed at the center of the map,and from the distance information between autonomous mobile robot and obstacles.But in case of active moving obstacle,many components and information need to process since their moving trace should be considered in real time.This paper proposes mobile robot's driving algorithm of unknown dynamic environment in order to drive intelligently to destination using ultrasonic and Global Positional System(GPS).Sensors adjusted the placement dependment on driving of robot,and the robot plans the evasion method according to obstacle which are detected by sensors.The robot saves GPS coordinate of complex obstacle.If there are many repeated driving,robot creates new obstacles to the location by itself.And then it drives to the destination resolving a large range of local minimum point If it needs an intelligent circumstantial decision,a algorithm is suited for effective obstacle avoidance and arrival at the destination by performing simulations.
