Abstract: A method for autonomous mower (110) navigation includes performing a training operation for an area including identifying a GPS signal associated with a training apparatus, iteratively recording data associated geolocations of the training apparatus as the training apparatus moves along a trajectory through the area, smoothing the geolocation data associated with the trajectory, and storing the smoothed geolocation data. The method can include subsequent to the training operation, performing a greens association process including establishing a link between the autonomous mower and an RTK-GPS base, receiving by the autonomous mower correction data from the RTK-GPS base (102), and determining an approach angle to a work area, wherein the path the autonomous mower travels to the work zone is defined by the approach angle.

Abstract: A mobile outdoor power equipment machine for performing a controlled task within a work area includes a drive system for providing movement of the machine, a working apparatus for performing the task, and a scanning system for scanning an area surrounding the machine. The scanning system is configured to provide detection of physical elements in the environment to aid in navigation of the machine. In an embodiment, the scanning system and a control system are configured to scan the area, determine the presence of a physical element in the area, determine that the physical element is located within the work area, determine the proximity of the physical element to the machine, determine a confidence level of whether the physical element is an animate being, and direct a behavior of the machine correlating to a combination of the confidence level and the proximity.

Abstract: An illumination mechanism includes a plurality of LEDs for illuminating a surface and is configured to determine whether one of the plurality of LEDs has faulted. A pair of LED sets is provided with the sets electrically connected in parallel via terminal connections of each set of LEDs. Regardless of at least one of environmental temperature or minor differences in minimum forward voltages of individual LEDs, the mechanism is configured to discern whether at least a single LED of one set of LEDs of the pair has faulted. In instances where the sets of LEDs are separated from a controller or voltage measurement circuitry, the cost, real estate consumption, and manufacturing complexity associated with additional wiring and connections are minimized.
