In this paper, we implement an unmanned delivery robot system with Robot Operating System(ROS)-based mobilemanipulator, and introduce the technologies employed for the system implementation. The robot consists of a mobilerobot capable of autonomous navigation inside the building using an elevator and a Selective Compliance AssemblyRobot Arm(SCARA)-Type manipulator equipped with a vacuum pump. The robot can determines the position andorientation for picking up a package through image segmentation and corner detection using the camera on themanipulator. The proposed system has a user interface implemented to check the delivery status and determine thereal-time location of the robot through a web server linked to the application and ROS, and recognizes the shipmentand address at the delivery station through You Only Look Once(YOLO) and Optical Character Recognition(OCR). Theeffectiveness of the system is validated through delivery experiments conducted within a 4-story building.
