  • Patent number: 10595501
    Abstract: A method for applying disinfectant to the teats of a dairy livestock includes determining that a stall of a rotary milking platform housing a dairy livestock is located adjacent to a track that has a carriage carrying a robotic arm. The method continues by communicating a first signal that causes operation of a first actuator such that the carriage moves along the track in relation to the rotary milking platform and independent of any physical coupling between the carriage and the rotary milking platform and in a direction corresponding to a direction of rotation of the rotary milking platform. The method concludes by communicating one or more additional signals that causes operation of one or more actuators of the robotic arm such that at least a portion of the robotic arm extends between the hind legs of a dairy livestock.

  • Patent number: 10595500
    Abstract: A system for operating a robotic arm, comprises a controller and a robotic arm. The controller accesses an image of the rear of dairy livestock located in a stall of a rotary milking platform 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: 10477828
    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.

  • Patent number: 10327414
    Abstract: A system for controlling the position of a robot carriage includes a linear carriage track positioned adjacent to a rotary milking platform, a robot carriage positioned on the carriage track such that the robot carriage may move along the carriage track, and a controller. The controller determines a rotational movement of a milking stall of the rotary milking platform, and determines a linear movement of the robot carriage on the carriage track corresponding to the rotational movement of the milking stall of the rotary milking platform. The controller further communicates a signal to a carriage actuator coupled to the robot carriage and the carriage track. The signal causes the carriage actuator to move the robot carriage along the carriage track according to the determined linear movement as the rotary milking platform rotates.

  • Patent number: 10327415
    Abstract: A system includes a robotic arm and a controller. The controller accesses a first image and a second image generated by a first camera. The controller determines a reference point based at least in part on the first image. The controller determines a position of a teat of the dairy livestock based at least in part on the second image. The controller instructs the robotic arm to grip a milking cup and move it towards the determined position of the teat between the hind legs of the dairy livestock from the rear. The controller then instructs the robotic arm to release the milking cup, to move in an upward direction towards an udder of the dairy livestock, and to move away from the teat.
