A STIGA autonomous robotic lawn mower is a brand-new generation of robot mowers by STIGA. They work without any perimeter wire, their boundaries are fully virtual and can be adjusted by the user at their preferences or needs. They are able to do so, because they navigate the garden thanks to GPS signal, combined with RTK (Real Time Kinematic) technology, which ensures their accuracy is around 2 cm while cutting. STIGA autonomous robots are equipped with a patented technology, called STIGA Active Guidance System, which allows the robot to plan cutting sessions ahead.
