Some example embodiments may provide a capability for intelligent control or management of a number of assets in connection with yard maintenance with the assistance or inclusion of a management unit having distributed properties. Thus, for example, sensor equipment and task performance equipment operation may be coordinated between local management and remote management entities for efficient monitoring and maintaining of lawn wellness.

Lawn monitoring and maintenance via a robotic vehicle

A robotic work tool comprising a work tool (), a tool damage detector () and a controller () for controlling the operation of the robotic work tool (), the robotic work tool () being configured to detect that the work tool () is damaged or lost by detecting an irregularity utilizing the tool damage detector () and thereby determining that the work tool () is damaged or lost.

A robotic vehicle may include control circuitry, a device interface and a detachable user interface. The control circuitry may be configured to execute stored instructions to direct operation of the robotic vehicle on a defined area. The device interface may enable electronic communication of a device with the control circuitry. The detachable user interface may be configured to be removably mated with the robotic vehicle to enable communication between the detachable user interface and the control circuitry via the device interface. The detachable user interface may provide user interface capability to enable an operator to define one or more setting parameters or instructions responsive to the detachable user interface being mated with the robotic vehicle for execution by the control circuitry to control operation of the robotic vehicle when the detachable user interface is not mated with the robotic vehicle.

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.

The present invention relates to a methodand a systemfor controlling a robotic garden toolaround a working areain a boundary wire aided system. The system includes the robotic garden toolto perform an operation within the working area, which is at least partly defined by a boundary. The boundary separates the working areafrom a non-working area. The robotic garden tool also includes detecting means for detecting the boundary. Further, the robotic garden toolis adapted to receive a status signalsent from a signal source and the robotic garden toolis configured to stop the operation, when the status signalprovides a stopping signal.
