Abstract

A system and method for an autonomous lawn mower comprising a mower body having at least one motor arranged to drive a cutting blade and to propel the mower body on an operating surface via a wheel arrangement, wherein the mower body includes a navigation system arranged to assist a controller to control the operation of the mower body within a predefined operating area.

First claim

1 . An autonomous lawn mower comprising:
a mower body having at least one motor arranged to drive a cutting blade and to propel the mower body on an operating surface via a wheel arrangement, wherein the mower body includes a navigation system arranged to assist a controller to control the operation of the mower body within a predefined operating area; wherein the mower body further includes a height adjustment system arranged to assist the controller to restrict the operation of the cutting blade within a predefined operating height.

2 . The autonomous lawn mower of claim 1 , wherein the height adjustment system includes one or more sensors arranged to detect the presence of the cutting blade at the predefined operating height.

3 . The autonomous lawn mower of claim 2 , wherein the height adjustment system is arranged to communicate with the controller for terminating the rotation of the cutting blade upon the cutting blade reaching the predefined operating height.

4 . An autonomous lawn mower comprising:
a mower body having at least one motor arranged to drive a cutting blade and to propel the mower body on an operating surface via a wheel arrangement, wherein the mower body includes a navigation system arranged to assist a controller to control the operation of the mower body within a predefined operating area; a detachable docking module arranged to receive the mower body; wherein the mower body further includes a sensor arranged to assist the controller to terminate the movement of the mower body upon the mower body is received by the detachable docking module.

5 . The autonomous lawn mower of claim 4 , wherein the detachable docking module includes a magnetic member arranged to communicate with the sensor.

6 . The autonomous lawn mower of claim 5 , wherein the mower body includes an opening within which the sensor is positioned.

7 . The autonomous lawn mower of claim 6 , wherein the magnetic member is inserted into the opening upon the mower body being received by the detachable docking module.

8 . An autonomous lawn mower comprising:
a mower body having at least one motor arranged to drive a cutting blade and to propel the mower body on an operating surface via a wheel arrangement, wherein the mower body includes a navigation system arranged to assist a controller to control the operation of the mower body within a predefined operating area; wherein the mower body further includes a heat absorbing unit on the outer surface of the mower body for directing the heat generated within the mower body towards the atmosphere.

9 . The autonomous lawn mower of claim 8 , wherein the heat absorbing unit provides a sealing means for protecting the mower body against moisture of the atmosphere.

10 . The autonomous lawn mower of claim 8 , wherein the controller is attached to the heating absorbing unit.

11 . The autonomous lawn mower of claim 10 , further comprising a heat conducting layer positioned between the controller and the heating absorbing unit.

12 . The autonomous lawn mower of claim 8 , wherein the heat absorbing unit is a heat sink.
