A communication system may include a robotic garden tool with an electronic processor that may be configured to determine (i) a plurality of relative distances between the robotic garden tool and an object as the object moves in the operating area, and (ii) one or more locations of the robotic garden tool as the object moves in the operating area. The electronic processor may be further configured to determine a respective location of the one or more locations of the robotic garden tool at a respective time at which data was captured that allowed for the determination of each relative distance of the plurality of relative distances. A virtual boundary may be generated using each relative distance in combination with the respective location of the robotic garden tool at the respective time at which the data was captured that allowed for the determination of each relative distance.

Creation of a virtual boundary for a robotic garden tool

A method of operating a mowing system, the method including mowing within a work area, wherein mowing is performed by a robotic lawn mower, and wherein the work area comprises a plurality of base stations each configured to charge the robotic lawn mower; determining when to charge the robotic lawn mower in view of a current charge level and a current location of the robotic lawn mower.

Robotic lawn mowers

A communication system includes an external device and a robotic garden tool. The external device is configured to generate a first key pair including a first private key for a robotic garden tool and a first public key for a server device. The external device transmits the first private key to the robotic garden tool, and transmits the first public key to the server device. The robotic garden tool is configured to receive an encrypted first instruction from the server device. The encrypted first instruction was encrypted by the server device using the first public key. The robotic garden tool is configured to decrypt the encrypted first instruction using the first private key to generate a decrypted first instruction. The robotic garden tool is configured to control operation of the robotic garden tool in accordance with the decrypted first instruction.

Generation of a cryptography key for a robotic garden tool

A mowing system including a base station disposed at a work area; and a plurality of robotic lawn mowers disposed at the work area, the plurality of robotic lawn mowers including a first robotic lawn mower and a second robotic lawn mower, wherein the base station is configured to communicate with the second robotic lawn mower through the first robotic lawn mower.
