Abstract: The present invention relates to a mobile robot platform system for process and production management. More specifically, the present invention relates to a mobile robot platform system for process and production management wherein a product may be transported flexibly and quickly by attaching a code mark to the floor of a driving route of an automated guided vehicle and recognizing the attached code mark to recognize the current position, driving speed, and driving route of a driving automated guided robot; in order to avoid obstacles in sequence, an obstacle detection unit is provided in the diagonal direction on a body frame of the automated guided robot to detect obstacles located in all directions of the driving route of the automated guided vehicle, and when the automated guided vehicle collides with an obstacle that is not detected by the obstacle detection unit, a collision detection unit detects the collision with the obstacle, and then the automated guided vehicle may drive normally by avoiding the collided obstacle, and may avoid sequential obstacles by moving forward and backward and left and right horizontally by means of the Mecanum wheel. To this end, the present invention comprises: a body frame modularized for each component mounting position in order to facilitate the detachment and attachment of components located therein; a plurality of obstacle detection units provided on the outside of the body frame to detect an obstacle located in a driving route; a collision detection unit provided on the outer surface of the body frame and configured to transmit a collision signal when colliding with an obstacle outside a detection range of the obstacle detection unit; a code mark recognition unit provided to recognize a code mark attached to the floor of the driving route to recognize a current position in the driving direction and the driving route; an upper housing coupled to the upper side of the body frame and provided with a robot operating device including a driving control unit and a rechargeable battery therein; a coupling unit to which a production management equipment including a manipulator and a camera can be coupled and which is formed on the upper side of the upper housing; a plurality of code marks attached to the driving route of the automated guided robot; a system control unit which receives a signal transmitted from a sensor including the obstacle detection unit, the collision detection unit, and the code mark recognition unit, performs an operation, and transmits an operation signal to a production management equipment control unit and a drive control unit; the production management equipment control unit which receives the signal transmitted from the system control unit and controls an operation of the production management equipment including a manipulator and a camera coupled to the coupling unit; the drive control unit which receives the signal transmitted from the system control unit and controls an operation of a driving device including Mecanum wheels; and the Mecanum wheels that are connected to each of independent driving motors provided on the front and back of both sides of the body frame, and are independently driven by driving signals of the driving control unit.
