1. A method of assisting a user of a robotic tool system, the robotic tool system comprising:
a self-propelled robotic tool configured to operate an area in an autonomous manner, and
a docking station that charges one or more batteries of the robotic tool, wherein the method comprises the steps of:
obtaining inclination data representative of an inclination angle of the robotic tool when the robotic tool is located on or at the docking station,
outputting a notification based on the inclination data,
obtaining current inclination data representative of a current inclination angle of the robotic tool,
comparing the current inclination data with historic inclination data representative of one or more historic inclination angle/angles of the robotic tool, and
outputting a notification based on a difference between the current inclination angle of the robotic tool and the one or more historic inclination angle/angles of the robotic tool.
