Abstract
Method and system for guiding a robotic garden tool () is disclosed. The robotic garden tool () may include at least two sensing means (, and). The robotic garden tool () is equipped to follow along a guiding wire () on a lawn (). While the robotic garden tool () moves along the guiding wire (), the sensing means (, and) may detect a magnetic field strength generated from current carrying guiding wire (). The method () and the system () is equipped to provide instructions to the robotic garden tool () to follow the guiding wire () based on the difference of magnetic field strength sensed by at least two sensing means (, and).
