The degree of this thesis aims to development for used to send the document in a small office by using path planning Algorithm. To bring the robot to work together with the theory of image processing and be a real trial by robot will walk along the path and use the camera (Pixy) survey and the position of the target. When checking the Yes or no if yes, to secure the goal to send the document but if not, it will bring the number to find out the direction of the target are processed further. Where to catch the target number and will use techniques of image processing in conjunction with letter recognition (Character Recognition) in several ways. To the robot's movement in many ways. Have the flexibility to change the path to the document delivery and accurate. The results 10 times the number of the robot to send the documents in the office is The robot can carry a weight of 0 g - 1000 g. The robot can walk by the way and can send documents to meet the target.
