NAVIGATION FOR A ROBOTIC WORKING TOOL
First Claim
1. A robotic lawnmower system, comprising a robotic lawnmower, said robotic lawnmower comprising a controller being configured tocause said robotic lawnmower to operate in a first operating mode, wherein the first operating mode is based on a current position, said current position being determined based on received signals that are received from a Global Navigation Satellite System device;
- determine that said received signals are not reliable, and in response thereto cause said robotic lawnmower to operate according to a second operating mode, wherein the second operating mode is not based on a current position being determined based on said received signals.
