An apparatus for applying a sealing and/or a coating substance to a component, in particular a vehicle body component. The apparatus includes kinematics, a spray device, and a sensor. The apparatus is configured to: a) acquire computer-aided design (CAD)-based information on the component; and in real time: b) acquire actual information on the component by the first sensor; c) create a movement profile for the kinematics and an application profile for the spray device on a basis of the CAD-based information and the actual information; and d) execute the movement profile and the application profile on the component.
