Abstract
The following quote was obtained by the news editors from the background informa tion supplied by theinventors: “Many contemporary robotic working tools, such a s robotic lawnmowers, are designed to workin a work area defined by a boundary, for example through the use of a boundary wire. Electrical roboticwork tools o perate inside the working area and are driven by battery power. To recharge the batteriesof the robotic work tool a charging station is used that the robotic w ork tool enters when the batterypower drops below a certain level or when an op erating program, such as a mowing program, is finished.Alternatively, the robot ic work tool is propelled using a combustion engine, in such an alternative, therobotic work tool is configured to enter a service station for example for taki ng on additional fuel.
