The present invention relates to a method for controlling a robotic device (300) by a control unit (CU) of a clipping machine (CM), the robotic device (300) being arranged in a system (1000) for producing sausage-shaped products (S) by filling a filling material into a tubular packaging casing supply (M) arranged on a filling tube (110, 130) of the clipping machine (CM), wherein the system (1000) comprises at least the clipping machine (CM) provided preferably with at least a first filling tube (110) and preferably a second filling tube (130) and a first and preferably a second casing brake assembly (120, 140), a storage device (200) for storing at least one tubular packaging casing supply (M), and a robotic device (300) for transferring a tubular packaging casing supply (M) from the storage device (200) onto a filling tube (110, 130) of the clipping machine (CM), wherein the control unit (CU) is adapted to provide control commands at least to the robotic device (300), and wherein the robotic device (300) includes a first gripper unit (340) for gripping a tubular packaging casing supply (M) and a second gripper unit (170) for gripping the first casing brake assembly (120), the method comprises the steps of: removing the casing brake assembly (120, 140) from the filling tube (110, 130) by the second gripper unit (170); moving the robotic device (300) into a take-up position for taking up by the first gripper unit (340) a tubular packaging casing supply (M) provided in a storage device (200, 700); gripping the tubular packaging casing supply (M) provided in a storage device (200, 700) by the first gripper unit (340); moving the robotic device (300) from the take-up position toward the filling tube (110, 130); transferring the tubular packaging casing supply (M) onto the filling tube (110, 130) by the first gripper unit (340); releasing the tubular packaging casing supply (M) onto the filling tube (110) of the clipping machine (CM) by the first gripper unit (640), and positioning the casing brake assembly (120, 140) on the filling tube (110, 130) by the second gripper unit (170).
