Abstract: A robotic garden tool includes at least one sensor configured to generate signals associated with an object within an operating area. A first electronic processor of the robotic garden tool receives, from the at least one sensor, an obstacle signal associated with an obstacle located within the operating area. The first electronic processor determines a first location of the robotic garden tool at a time corresponding to when the first electronic processor received the obstacle signal. The first electronic processor determines a second location of the obstacle based on the obstacle signal and the first location of the garden tool. The first electronic processor generates mapping information of the operating area that includes a virtual boundary based on the second location of the obstacle. The first electronic processor controls the robotic garden tool in the operating area to remain outside of the virtual boundary based on the mapping information.

Abstract: A base station device includes a network interface including a global navigation satellite system (GNSS) receiver and an electronic processor. The electronic processor may be coupled to the network interface. The electronic processor may be configured to receive, via the GNSS receiver, a first location signal from each of a first plurality of satellites while the base station device is located at a first location. The electronic processor may also be configured to determine a first signal strength of the base station device at the first location. The first location may be a first potential location of the base station device from which the base station device is configured to provide location calibration information based on communication with the first plurality of satellites to a robotic garden tool. An indication of the first signal strength may be output via an output device for consumption by a user.
