Object recognition and fetching method, and object recognition and fetching system making the fixed fetching unit and the movable fetching unit simultaneously and separately fetch the objects

An object recognition and fetching method recognizes that there are multiple objects placed in a storage box, and calculates relative coordinates between a fixed fetching unit on a fetching fixture of a robotic arm and a symmetric center point of each object, and one of the relative coordinates is used as a target coordinate. A distance between a movable fetching unit and the fixed fetching unit on the fetching fixture is adjusted according to the target coordinate and other relative coordinates, and a horizontal rotation angle of the fetching fixture is determined. According to the horizontal rotation angle and the target coordinates, the robotic arm is controlled to move the fetching fixture until the fixed fetching unit and the movable fetching unit are aligned with the symmetric center point of each object, so as to make the fixed fetching unit and the movable fetching unit simultaneously and separately fetch the objects, and place the fetched objects to preset positions.
