Robotic working tool system and method
The present disclosure relates to a robotic working tool system comprising a robotic working tool ( 1 ), and a navigation arrangement enabling the robotic working tool to navigate within a working area ( 3 ) defined by a working area boundary ( 13 ). A recording unit ( 62 ) is used to establish at least first and second sub-areas ( 21 - 47 ), defined by closed perimeters. A mapping unit ( 60 ) is used to provide the working area to the robotic working tool ( 1 ) as a composite area ( 49, 51 ) with a closed perimeter, which is defined by the union of said first and second sub-areas ( 21 - 47 ).
1 . A robotic working tool system comprising a robotic working tool, and a navigation arrangement enabling the robotic working tool to navigate within a working area defined by a working area boundary, characterized by
a recording unit configured to establish at least a first sub-area, defined by a first closed perimeter, and a second sub-area, defined by a second closed perimeter; and
a mapping unit configured to provide said working area to the robotic working tool as a composite area with a closed perimeter, the composite area being defined by a union of said first and second sub-areas,
wherein the first and second sub-areas are non-contiguous and separated by a non-working area,
wherein the recording unit is further configured to record a transition path from the first sub-area to the second sub-area through the non-working area, and
wherein the transition path is included in the composite area.
2 . The robotic working tool system according to claim 1 , wherein at least one sub-area is tagged with a property.
3 . The robotic working tool system of claim 1 ,
wherein the composite area is defined by the second sub-area minus an overlap between said first and second sub-areas.
4 . A method for operating a working tool system, the system comprising a robotic working tool, the method comprising recording a first sub-area, defined by a first closed perimeter, and a second sub-area, defined by a second closed perimeter, establishing a composite area with a closed perimeter, the composite area being defined by a union of said first and second sub-areas, and navigating the robotic working tool using the composite area,
wherein the first and second sub-areas are non-contiguous and are separated by a non-working area,
wherein a recording unit is further configured to record a transition path from the first sub-area to the second sub-area through the non-working area, and
wherein the transition path is included in the composite area.
5 . The method of claim 4 ,
wherein the method further comprises establishing the composite area as being defined by the second sub-area minus an overlap between said first and second sub-areas.
6 . A method for operating a working tool system, the system comprising a robotic working tool, the method comprising:
recording via a recording unit at least a first sub-area, defined by a first closed perimeter, and a second sub-area, defined by a second closed perimeter, establishing a composite area with a closed perimeter, wherein the first and second sub-areas are at least partly overlapping, and
navigating the robotic working tool via a navigation unit by processing, in a first step, one of an overlap between the first and second sub-areas and a complement to the overlap between the first and second sub-areas and, in a second step, the other of the overlap between the first and second sub-areas and the complement to the overlap between the first and second sub-areas
wherein the first and second sub-areas include a portion that is non-contiguous and are separated by a non-working area,
wherein the recording unit is further configured to record a transition path from the first sub-area to the second sub-area through the non-working area, and
wherein the transition path being included in the composite area.
