Abstract: A method and system for fostering controlled growth of a turfgrass in a target area, includes: providing an autobot capable of automatically applying a UVC light treatment to the target grass area, wherein the target grass area comprises C4 turfgrass. The method and system includes coupling a UVC light subsystem to the autobot such that the UVC light subsystem is suspended above the C4 turfgrass within the target grass within a first predetermined range. Next, UVC light is generated by the UVC light subsystem with a wavelength within a second predetermined range. Subsequently, the UVC light is emitted from the UVC light subsystem to the C4 turfgrass at an intensity within a third predetermined range. And the UVC light is moved across the C4 turfgrass within the target grass area using the autobot at night at a speed within a fourth predetermined range.

Abstract: Disclosed is an autonomous robot to remove pathogens from a target area such as a grass field, turf field, or yard. Embodiments include an ultraviolet light subsystem that generates ultraviolet radiation operable to remove the pathogens from the target area as the autobot advances along the coverage path.
