Patent ID: 8726843

Claim:
A system for applying a substance to the teats of a dairy livestock, comprising: a milking stall operable to house a dairy livestock; a robotic arm positioned adjacent the milking stall and operable to extend between the hind legs of the dairy livestock; and a spray tool coupled to the robotic arm and operable to discharge a substance to at least some of the teats of a dairy livestock, wherein the spray tool comprises: a linear member operable to rotate about an axis that is perpendicular to the robotic arm, wherein the linear member has a perimeter that lies within an outer perimeter of the robotic arm when the robotic arm extends between the hind legs of the dairy livestock; a first spray nozzle coupled to the linear member proximate a first end of the linear member; and a second spray nozzle coupled to the linear member proximate a second end of the linear member; wherein the first and second spray nozzles are operable to discharge the substance in a substantially circular pattern as the linear member rotates about the point of attachment.
