Embodiment Construction

[0028] In the following part of the description, an exemplary embodiment of controlling the automatic lawn mower to move to a predetermined position, especially through a narrow passage, will be described in detail.

[0029] figure 1 Shown is a schematic diagram of a system for implementing the method for controlling the movement of the robotic lawnmower 2 to a predetermined position. Robotic lawn mower 2 includes sensors 12 , 14 , 17 and 19 . The robotic lawn mower 2 , which can also be called a self-propelled lawn mower, is powered by batteries and needs to be recharged at a charging station 6 at regular intervals. The robot mower 2 is configured to move within the area A enclosed by the boundary line 4 during operation. In order to make the drawings show more clearly, the automatic lawnmower 2 is enlarged and shown. The boundary line 4 can be set in any form to form an area A that limits the movement of the robotic lawn mower 2 . Such as figure 1 As shown, the boundary...

Abstract

A method controls a robotic mower (2) to a predetermined position by means of a guide wire (8). The robotic mower comprises a control unit (22) and at least one sensor (12; 14; 16; 17; 19). At least one of the sensors detects a signal from guide wire and follows the guide wire at a first distance that is randomly determined. The robotic mower follows the guide wire until detecting, by means of atleast one sensor, a signal from a boundary wire (4) and then following the boundary wire at a second distance, which is randomly determined. When detecting that the signal strength from the guide wirefalls outside a first predetermined threshold, the robotic mower starts following the guide wire again. And a robotic mower is controlled by the method described above.

Description

technical field [0001] The present invention generally relates to a robotic lawn mower and a method of controlling a robotic lawn mower to pass through a path to and from a charging station, and more particularly, to a method of controlling a robotic lawn mower to pass through a narrow passage. Background technique [0002] Robotic lawn mowers, also known as self-propelled lawn mowers, are well known. These robotic lawn mowers come with rechargeable batteries. When the remaining charge in the battery falls below a certain level, the robotic lawnmower will be configured to return to the charging station to recharge the battery. In the prior art, there are many methods for controlling the automatic lawn mower to return to the charging station. One common approach is for an autonomous lawnmower, upon receiving a command to return to a charging station, to continue moving until it detects a boundary line, and then follows the boundary line to a charging station located somewhe...
