  • Publication number: 20190327886
    Abstract: An autonomous lawn mower (100) and a system for navigating the same are disclosed. The autonomous lawn mower (100) comprises a mower body (102) having at least one motor (210) arranged to drive a cutting blade (212b) and to propel the mower body (102) on an operating surface via a wheel arrangement. The mower body (102) includes a navigation system (204) arranged to assist a controller (202) to control the operation of the mower body (102) within the predefined operating area (208). The system comprises a plurality of navigation modules (202), each arranged to obtain individual navigation information associated with the navigation of the autonomous mower (100). The navigation modules (202) operate to generate a virtual representation of the operation area (208) of the lawn mower (100) during an initialization mode, and the virtual representation of the operation area (208) is processed with the obtained navigation information during the operation of the lawn mower (100).
