Problems solved by technology

[0005] Also, since the user has to manually enter all altitudes, it is more difficult to specify the correct map to use with the GPS system
Even if GPS is used to generate maps, the low accuracy of GPS will inevitably lead to incorrect maps

Abstract

The invention provides a 3D map generation by a robotic work tool. The robotic work tool (100) comprises an altitude sensor (185) for providing a current altitude reading (HRL) and a controller (110) is configured to: receive the current altitude reading (HRL) from the altitude sensor (185); determine an altitude (H) based on the current altitude reading (HRL); determine a current position; and generating a map indicating elevations by including the determined altitude (H) for the current position in the map. A robotic work tool system (200) comprises a robotic work tool (100) and a reference altitude sensor (285) for providing a reference altitude reading (HCS), wherein the robotic work tool (100) is further configured to: receive the reference altitude reading (HCS) from the reference altitude sensor (285); and determine the altitude (H) based on the current altitude reading (HRL) and the reference altitude reading (HCS).

Description

technical field [0001] The present application relates to a method and a robotic work tool system for improved map generation by a robotic work tool. Background technique [0002] Contemporary robotic work tools are becoming increasingly sophisticated and capable of performing increasingly advanced tasks, such as performing advanced modes of operation. In the example of a lawnmower robot, an advanced work pattern may be a complex mowing pattern based on the layout of a garden including bushes, garden islands, and other structures. [0003] Advanced modes of operation are often general in their planning and do not necessarily take into account all aspects of the garden (such as elevation changes). Steep slopes can make it difficult for a robotic work tool to perform a given mode of operation, as the robotic work tool cannot traverse the slope or begins to slide. [0004] To successfully navigate this complex mode of operation, some contemporary robotic work tools employ sat...
