The invention relates to a robot system comprising (I) a robot (100) for guiding an application part (300). The robot (100) has the following: (a) a robot arm (110) with a base (112), a region (114) which is proximal to the base (112), a region (116) which is distal to the base (112), and a securing device (130) for securing the application part (300), in particular in a removable manner, said securing device (130) being arranged in the distal region (116); b) a grounding (180); and (c) a cable (200) for connecting to the application part (300) and to a control device (500), in particular in a removable manner, comprising at least one signal line (250) and/or at least one energy supply line (240), a protection conductor (230), a distal connection means (140) for electrically connecting the application part (300) to the cable (200), in particular in a removable manner, and a proximal connection means (150) for electrically connecting the control device (500) to the cable (200), in particular in a removable manner; and (II) an adapter (400) which has an electric line for (410) for electrically connecting the protection conductor (230) of the cable (200) to the grounding (180) of the robot (100), in particular in a removable manner. The invention further relates to a method for producing a robot system of the aforementioned type and to a use of a robot system of the aforementioned type.
