Robotic work tool system and a charging connector arrangement for a robotic work tool system

A robotic lawnmower system, comprising:

• a service station;
• and
• a robotic lawnmower, said robotic lawnmower comprising at least one corresponding connector arranged on an upper side of the robotic lawnmower,
• wherein said service station comprises at least one mating connector and a supporting structure arranged to carry said at least one mating connector and to extend over said robotic lawnmower as the robotic lawnmower enters a first end of the service station for establishing an energy transfer contact between the at least one corresponding connector of the robotic lawnmower and the at least one mating connector of the service station from above,
• wherein said supporting structure is configured to allow the robotic lawnmower to select to exit between a second end of the service station by driving through the charging station and the first end of the charging station by reversing from the charging station, and
• wherein said energy transfer is a transfer of fuel and said at least one corresponding connector is a fuel inlet.
