  • Publication number: 20140318470
    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, and remains extended between the legs of the dairy livestock as the stall rotates adjacent to the robotic arm.

  • Patent number: 8826858
    Abstract: In certain embodiments, a system includes a front wall, a rear wall positioned substantially parallel to the front wall, and first and second side walls each extending between the front wall and the rear wall. The first side wall includes a gate, and the second side wall is spaced apart from the first side wall such that the front wall, the rear wall, the first side wall, and the second side wall define a milking box stall of a size sufficient to accommodate a dairy livestock. The system includes an equipment portion located adjacent to the rear wall. The equipment portion houses a robotic attacher configured to extend between the rear legs of a dairy livestock located within the milking box stall in order to attach milking equipment to the dairy livestock.

  • Publication number: 20140245958
    Abstract: A method, comprises receiving a flow of milk at an inlet of a manifold. The inlet comprises a first end coupled to a hose that receives a flow of milk from a teat cup and a second end terminating in a chamber of the manifold. The manifold comprises one or more other inlets and a plurality of outlets. The plurality of outlets includes one or more milk collector outlets and one or more drain outlets. The method proceeds by causing the flow of milk to be directed to a corresponding milk collector outlet by causing a shut-off valve corresponding to the inlet to open, and by causing a drain valve corresponding to the inlet to close. The method concludes by causing the flow of milk to be directed to a corresponding drain outlet by causing the shut-off valve corresponding to the inlet to close, and by causing the drain valve corresponding to the inlet to open.

  • Publication number: 20140230750
    Abstract: A method for applying disinfectant to the teats of a dairy livestock, comprises receiving a trigger signal indicating that a stall of a rotary milking platform housing a dairy livestock is located adjacent to a track, the track having a carriage carrying a robotic arm mounted thereto. The method continues by communicating a first signal to a first actuator coupled to the track and the carriage, the first signal causing operation of the first actuator such that the carriage moves along the track in relation to the rotary milking platform. The method concludes by communicating one or more additional signals to one or more actuators of the robotic arm, the one or more additional signals causing operation of the 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: 8800487
    Abstract: A system includes a carriage track positioned adjacent to a rotary milking platform, a robot carriage mounted to the carriage track, and a controller. The controller is operable to receive both a first rotary encoder signal indicating a first rotational position of a milking stall of the rotary milking platform (corresponding to a starting linear position of the robot carriage) and a second rotary encoder signal indicating a second rotational position of the milking stall. The controller is further operable to determine, based on a difference between the first and second signals, a desired linear position of the robot carriage on the carriage track (a position corresponding to the second rotational position of the milking stall). The controller is further operable to communicate a position signal to a carriage actuator, the position signal causing the carriage actuator to move the robot carriage to the desired linear position.

  • Publication number: 20140216349
    Abstract: A system includes a milking box and a robotic arm. The milking box comprises a stall portion that houses a dairy livestock with four teats. The robotic arm performs the following operation for a plurality of teats of the dairy livestock: retrieves a cup; attaches the cup to a teat; and detaches the cup from the teat. The cup is maintained 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 an equipment area of the milking box after it is detached from the last teat of the dairy livestock.

  • Publication number: 20140196665
    Abstract: A system includes a robotic arm on which at least one camera is attached. It further includes a memory and a controller communicatively coupled to the memory. The memory stores historical information associated with a dairy livestock. The historical information include a previously-determined location of a teat of the dairy livestock. The controller moves the camera on the robotic arm toward the previously-determined location of the teat. The camera generates an image of the teat of the dairy livestock from a position to which it is moved, and the controller determines a current location of the teat of the dairy livestock based at least in part on the image.
