  • Publication number: 20170295745
    Abstract: A method for applying disinfectant to the teats of a dairy livestock comprises moving a robotic arm along a track in relation to a rotary milking platform housing a dairy livestock and independent of any physical coupling between the robotic arm and the rotary milking platform. The rotary milking platform has a substantially circular perimeter. The track is positioned outside the perimeter of the rotary milking platform. At least a portion of the track is straight and offset in relation to the rotary milking platform. The robotic arm comprises an arm member operable to pivot about an axis that is parallel to the track, and a spray tool attached to one end of the arm member. The method further comprises extending the robotic arm between the hind legs of the dairy livestock while the rotary milking platform rotates such that the spray tool is located at a spray position from which it may discharge disinfectant to the teats of the dairy livestock.

  • Publication number: 20170265425
    Abstract: A system for operating a robotic arm, comprises a camera, a controller and a robotic arm. The camera captures an image of a rear of a dairy livestock located in a stall of a rotary milking platform. The controller receives the image and in conjunction with the stall of the rotary milking platform in which a dairy livestock is located moving into an area adjacent a robotic arm, determines whether a milking cluster is attached to the dairy livestock based at least in part upon the image. The robotic arm is communicatively coupled to the controller and extends between the legs of the dairy livestock if the controller determines that the milking cluster is not attached to the dairy livestock. The robotic arm does not extend between the legs of the dairy livestock if the controller determines that the milking cluster is attached to the dairy livestock.

  • Patent number: 9763424
    Abstract: A system includes a controller and a robotic arm. The controller accesses an image signal of an udder of a dairy livestock, and determines a spray position by processing the accessed image signal to determine a tangent at the rear of the udder and a tangent at the bottom of the udder. The spray position is a position relative to the intersection of the two tangents. A robotic arm communicatively coupled to the controller positions a spray tool at the spray position.
