A green area maintenance system includes a motor scythe, a scythe position determining device for determining scythe position coordinates, and a position recording device. The scythe position determining device is attached to the motor scythe. The position recording device is designed for recording a series of scythe position coordinates of a delimiting border while the motor scythe is being guided together with the scythe position determining device along the delimiting border of an area to be maintained.

Green area maintenance system, method for sensing at least one section of a delimiting border of an area to be maintained, and method for operating an autonomous mobile green area maintenance robot

A green area maintenance system includes an autonomous mobile green area maintenance robot having a treatment tool and a cutting tool differing from the treatment tool. The robot and the cutting tool are configured to allow fixing of the cutting tool to the robot. The system includes a user control device, and has an autonomous operation mode and a cutting operation mode. In the autonomous operation mode the autonomous mobile green area maintenance robot with its treatment tool operates autonomously and the cutting tool is set out of operation, and in the cutting operation mode the cutting tool is fixed to the green area maintenance robot and operable. The robot with its treatment tool and cutting tool are controlled by a user via the user control device, and an operation mode switching device for switching between the autonomous operation mode and the cutting operation mode.

Green area maintenance system and method for identifying at least a section of a boundary edge of an area to be treated

A autonomous mobile green area maintenance robot, includes: a first motor-driven treatment tool, a second motor-driven treatment tool differing from the first treatment tool, and an open protective housing with a lateral rim. The first treatment tool defines a first treatment zone and is arranged within the protective housing such that the first treatment zone is located in a safety zone of the protective housing. The safety zone has a safety distance to the lateral rim. The second treatment tool defines a second treatment zone, wherein the second treatment zone is located at least partially beyond the safety zone. The autonomous mobile green area maintenance robot has an autonomous operation mode, wherein in the autonomous operation mode, a maximum kinetic energy of the second motor-driven treatment tool is smaller than a maximum kinetic energy of the first motor-driven treatment tool.

The invention relates to a method for operating a self-propelled lawnmower, which is moved on a surface (). The surface () is surrounded by a border delimitation wire () on which electrical signals () are transmitted. The transmitted signal () is received by at least one receiving coil () in the lawnmower () and induces a reception signal (EI), which is evaluated in an evaluation unit (). The evaluation unit () emits an output signal to a control unit (), on the basis of which the control unit () controls the direction of travel of the lawnmower (). In order to guarantee a safe operation of the lawnmower even in range of electromagnetic interference fields, the invention provides that the electrical signal () is transmitted with a predetermined pattern (M). The evaluation unit () of the lawnmower () processes the reception signal (EI) as a pattern, wherein the pattern (M') of the reception signal (EI) is compared to a predetermined reference pattern (RM). Information regarding the location of the lawnmower () inside or outside the border delimitation wire () is obtained from the comparison result. The control unit () will determine the direction of travel of the implement on the basis of this information.
