The processing system (10) serves for processing a moving workpiece (12) by means of an industrial robot (16) that can be rigidly coupled, intermittently, to the workpiece (12) and/or to a movable workpiece carrier unit (14), the industrial robot (16), when in a decoupled operating position (42), being carried by a carrier device (18) that is movable, independently of a workpiece, by means of a drive unit (20) acting with active drive, and, when in a coupled operating position (44), being floatingly mounted relative to the carrier device (18) by means of a floating bearing system (22), characterized in that a control unit (36) of the industrial robot (16) and/or at least one production unit (40) are additionally arranged on the carrier device (18).
