Embodiment Construction

[0025] Embodiments of the invention are described below, by way of example only. These examples represent the best mode currently known to applicants to put the invention into practice, but they are not the only way in which this purpose can be accomplished.

[0026] from mobile device

[0027] figure 1 is a schematic illustration of a self-propelling device in the form of a robotic lawnmower 1 according to some embodiments of the invention. The robotic lawnmower 1 comprises a housing or 3 and a mobile module 5 . The movement module 5 may eg comprise one or more wheels driven by a drive motor (not shown) to actuate the robot mower 1 to move forward or backward and / or to perform a turn. Embodiments of the present invention may include other kinds of movement modules as known in the art as are appropriate for the plant's propulsion system. Embodiments of the invention may include so-called "floating chassis" devices, which have a chassis that can contact the ground and be li...

Abstract

A self moving device and control method are disclosed in which the self moving device comprises a magnetic field sensor for detecting a static magnetic field in the vicinity of the device. The method comprises instructing the device to retreat in response to detection of a first predetermined pattern of the magnetic field strength detected by the magnetic field sensor, verifying that the retreat instruction has been executed based on detected magnetic field strength, and generating an alert if the retreat instruction is not executed A magnetic boundary system comprises a magnetic strip having two ends and a connector, wherein: the magnetic strip provides a magnetic field having a polarity in a direction transverse to the length of the magnetic strip, the connector is designed to connect one end of the magnetic strip to the other end or to one end of a similar magnetic strip, and the strip and connector are designed such that the strip is prevented from rotating in the connector and the ends are accommodated such that the angle between the polarities is less than 180 degrees.

Description

[0001] The present invention is in the field of self-mobile devices, also commonly referred to as autonomous vehicles, such as (but not limited to) devices used to perform household tasks, such as robotic lawnmowers and vacuum cleaners. The invention also relates to methods of controlling self-mobile devices, systems for defining areas in which such devices may or may not operate, and systems comprising one or more self-mobile devices. Background technique [0002] Sometimes it is desirable to restrict the area within which a mobile device travels, for example by defining an area into which the device is prevented or within which the device is confined. It is known to use wires to constrain the travel of robotic lawnmowers, where an electric field is induced in combination with an inductive sensor in the lawnmower. This has a number of disadvantages including the need to introduce a magnetic field, which requires power consuming equipment and is cumbersome to rearrange to acco...
