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.

Method for operating a system of self-driving ground working devices

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.

Ground working system with at least one intensive zone

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.

Ground working system with an endless boundary wire

A ground working system has at least one self-driving ground working device, wherein the operating region (A) of the ground working device is determined by an edge boundary. The ground working device travels automatically within the operating region (A) along a traveling path (W), wherein the ground working device has a drive, a control unit and an in-device battery for supplying energy to the ground working device. A charging station for charging the battery of the ground working device is also provided. The charging station is set up on the edge boundary without interrupting the edge boundary. The ground working device goes to the charging station for charging the battery as required.

Ground working system with multiple charging stations

A ground working system includes at least one self-driving ground working device, which has a drive and a control unit. An operating region (A) is bounded by a wire, wherein the ground working device travels along a traveling path (W) determined by the control unit in the operating region (A). A base station has a transmission unit, which is electrically connected to the wire and by which a wire signal is transmitted. The wire signal transmitted on the wire is electrically received by a reception unit of the base station, compared with a predetermined setpoint signal and, in the event of a deviation of the electrically received wire signal from the predetermined setpoint signal, the transmitted wire signal is changed.

Ground working system with signal adaptation

A ground working system has at least one self-driving ground working device with a drive, a control unit and an in-device battery for supplying energy to the ground working device. An operating region (A), within which the ground working device travels automatically along a traveling path (W), is determined by an edge boundary. At least one charging station for charging the battery of the ground working device via an electrical energy-transferring charging connection is provided. The charging connection is also configured as a data connection for the transmission of data packets.
