Abstract
The present invention relates to a method () and a system () for guiding a robotic garden tool to a predetermined position. The robotic garden tool includes a control unit () and a sensor unit () to detect guiding signals. The sensor unit () detects a first guiding signal () from a first signal source () and the robotic garden tool follows the first guiding signal () at a variable distance from the first signal source () towards the predetermined position. While within a predetermined distance (D) from the predetermined position, the sensor unit () detects a second guiding signal () from a second signal source (). Within the predetermined distance (D), the robotic garden tool follows one of the first and the second guiding signals (or) towards the predetermined position at a pre-configured distance from the corresponding signal source.
