  • Patent number: 10349618
    Abstract: A method includes housing a dairy livestock in a stall portion of a milking box and retrieving, by a robotic attacher, a cup. For each of a plurality of teats of a dairy livestock, the method further uses the robotic arm to perform the steps of attaching the cup to the teat, detaching the cup from the teat, and maintaining the cup within the stall portion of the milking box from the time that the cup is attached to the first teat of the dairy livestock through the time that the cup is attached to a last teat of the dairy livestock. The method concludes by retracting the cup into an equipment area of the milking box after detaching the cup from the last teat of the dairy livestock.

  • 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.

  • 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.
