  • Publication number: 20170035017
    Abstract: A system comprises a robotic arm, camera, and a controller. The camera is positioned on a surface of the robotic arm and emits a laser signal at an upward, non-zero angle relative to a longitudinal axis of the robotic arm. The controller instructs the robotic arm to grip a milking cup, and determines a position of a teat of the dairy livestock based at least in part upon the non-zero angle of the laser signal emitted by the camera. The controller instructs the robotic arm to move the milking cup towards the determined position of the teat between the hind legs of the dairy livestock from the rear, release the milking cup in response to the milking cup being attached to the teat. move in an upward direction towards an udder of the dairy livestock in conjunction with the robotic arm releasing the milking cup, and to move away from the teat.

  • Publication number: 20170006819
    Abstract: A system includes a camera, a controller and a robotic arm. The camera generates an image of an udder of a dairy livestock. The controller determines a position of the udder of the dairy livestock based at least in part upon the image. The controller further determines a spray position based at least in part upon the determined position of the udder of the dairy livestock. Determining the spray position includes processing the accessed image 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. The robotic arm is communicatively coupled to the controller and positions a spray tool at the spray position.

  • Publication number: 20170006818
    Abstract: A system includes a robotic arm positioned in an equipment area of a milking box that includes a stall portion housing a dairy livestock with four teats. The robotic arm retrieves a cup, and for a plurality of teats of the dairy livestock, the robotic arm attaches the cup to a teat, detaches the cup from the teat, and maintains the cup within the stall portion of the milking box from the time that the cup is attached to a first teat of the dairy livestock through the time that the cup is attached to a last teat of the dairy livestock. The cup is retracted into the equipment portion of the milking box after it is detached from the last teat of the dairy livestock.

    Abstract: A system for operating a robotic arm comprises a carriage and a robotic arm. The carriage is mounted on a track adjacent to a rotary milking platform having a substantially circular perimeter and a stall for a dairy livestock. The carriage moves along a substantially straight portion of the track tangent to and outside the perimeter of the rotary milking platform at a rate based at least in part upon a speed of rotation of the rotary milking platform. The carriage moves in a direction corresponding to the direction of rotation of the rotary milking platform and such movement of the carriage is independent of any physical coupling between the carriage and the rotary milking platform. The robotic arm extends between the legs of the dairy livestock.

  • Publication number: 20160353699
    Abstract: A system comprises a milking box, a robotic attacher, a sensor, and a controller. The milking box has a stall to accommodate a dairy livestock. The stall comprises a first exit gate on a first side of the stall leading to a first sorting region and a second exit gate on a second side of the stall leading to a second sorting region. The robotic attacher extends from the rear between the hind legs of the dairy livestock. The sensor identifies the dairy livestock within the milking box stall.

  • Publication number: 20160353700
    Abstract: A system 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 from a first linear position to a second linear position, and a controller. The controller determines a movement of a milking stall of the rotary milking platform from a first rotational position to a second rotational position. The controller further determines the second linear position of the robot carriage on the carriage track corresponding to the movement of the milking stall of the rotary milking platform. The controller also communicates a position signal to a carriage actuator coupled to the robot carriage and the carriage track. The position signal causes the carriage actuator to move the robot carriage along the carriage track from the first linear position to the second linear position in conjunction with the movement of the rotary milking platform.
