Abstract: A system (S) has at least a first and a second self-driving ground working device for combined working of a predetermined operating region (A). An individual ground working device travels autonomously along a random path inside the operating region. The system has at least one base station for communication with the ground working devices. For a method for setting up and operating the system, provision is made that information relating to an operating variable (B) stored in one ground working device is transmitted to further ground working devices, that a ground working device travels autonomously along a random path (W) inside the operating region, independently of another ground working device, by using the operating variable, and that during the operation of the system of ground working devices the behavior of an individual ground working device is adapted as a function of changes in the operating variable.

Abstract: A ground working system having at least one self-driving ground working device, wherein the ground working device has a drive, a control unit and an in-device battery for supplying energy to the ground working device. An operating region (A) determined by an edge boundary is provided for the ground working device, wherein the ground working device travels over an operating path (W) determined by the control unit within the operating region (A). In order to meet requirements for a differing working intensity of specific regions of an area, it is provided to predetermine at least one intensive limit, an intensive limit in each case demarcating an intensive region (B). The ground working device in an intensive mode works the intensive region (B) with preference.

Abstract: A ground working system includes at least one self-driving ground working device having a drive, a control unit and a battery. An operating region is determined by a boundary wire, wherein the ground working device travels over a traveling path determined by the control unit in the operating region. Connected to the boundary wire is a first base station, which transmits a signal on the boundary wire. The electromagnetic field of the signal induces a reception signal in the reception coil of the ground working device. The reception signal is processed in the control unit. In order to make a stable signal available over the entire length of the boundary wire, it is provided that the boundary wire is electrically connected to a further base station configured as a repeater, which receives the signal transmitted by the first base station, processes it and passes it on.
