A robotic mower boundary sensing system includes a boundary driving circuit on a charging station transmitting an encoded signal on a boundary wire, a boundary sensor on a robotic mower and including an inductor receiving the encoded signal, and a vehicle control unit on the robotic mower receiving the encoded signal from the boundary sensor and decoding the signal and cross correlating the received signal to determine the distance of the boundary sensor from the boundary wire.

A robotic mower launch point system includes a user interface for an operator to enter a plurality of launch point locations, durations and frequencies, and a vehicle control unit that stores the locations, durations and frequencies, determines a sequence of launches based on the launch point frequencies, and commands the robotic mower to exit a charging station and follow a boundary wire to each launch point in the sequence where the robotic mower mows for that launch point's duration before returning to the charging station. The vehicle control determines the sequence based on the frequency of each launch point relative to a total of the launch point frequencies.

A robotic mower home finding system includes a charging station connected to an outer boundary wire loop, and a vehicle control unit on the robotic mower that directs a traction drive system to drive the robotic mower along a path offset a specified distance from an outer boundary wire loop toward the charging station. The vehicle control unit changes the specified distance randomly or incrementally so that the robotic mower does not take the same path to the charging station each time.

A system and method for positioning a mobile machine, such as a robot, using a tether line connected between two mobile machines. A first mobile machine, such as a boundary vehicle, is controlled to move along a path, such as a boundary defining an area. The first machine employs a localization device to determine and maintain its position on the path. A tether line is connected between the boundary vehicle and a second mobile machine, such as a roving vehicle. The first machine determines the position of the second machine relative to the first machine from a length of extension and angle of the tether line. The first machine controls movement of the second machine to perform a task or mission, such as a task performed in the area defined by the boundary.

A visor clip of unitary construction is presented along with a method for manufacture. The visor clip includes an engagement portion that frictionally engages with an engagement target, which may be a sun visor in an automobile. A payload portion is designed to receive and frictionally couple to a payload, where the payload may include a number of small objects such as toothpicks. The payload portion includes a number of extended portions on one or more of the surfaces that define the payload portion. The inclusion of the extended portions provides a number of force application points that enhance the frictional engagement of the payload.
