A method () of assisting a user of a robotic tool system () is disclosed. The robotic tool system () comprises a self-propelled robotic tool () configured to operate an area in an autonomous manner and a docking station () for charging one or more batteries () of the robotic tool (). The method () comprises the steps of obtaining () inclination data representative of an inclination angle (a, a, a) of the robotic tool () when the robotic tool () is located on or at the docking station () and outputting () a notification (n, n, n) based on the inclination data. The present disclosure further relates to a robotic tool () and a robotic tool system () comprising a robotic tool () and a docking station ().

Method of assisting a user of a robotic tool system, robotic tool, and robotic tool system

A robotic work tool system may include a robotic work tool. The robotic work tool may include two front wheels and a chassis. The robotic work tool is characterized in that the two front wheels are arranged on a beam axle that is pivotably arranged to the chassis.

Robotic working tool

A robotic work tool system () comprising a robotic work tool () comprising a lift/collision detection sensor (), said lift/collision detection sensor () comprising a polarity element () and at least a first sensing element (') and a second sensing element (&#x2033;), wherein the polarity element () has a first and a second polarity and wherein the first and second sensing elements are configured to each sense a polarity of the first polarity element (). The robotic work tool () is configured to detect a polarity change in the first sensing element (&#x2032;) and in the second sensing element (&#x2033;) and in response thereto determine that a lift has been detected, or detect a polarity change in the first sensing element (&#x2032;) but not in the second sensing element (&#x2033;) and in response thereto determine that a collision has been detected.
