  • Patent number: 9510553
    Abstract: A combined teat position and breeding rating determining arrangement for a milking system having a milking stall, a movable robot arm for automatically attaching teat cups to the teats of the milking animal, and a control device for controlling the movement of the robot arm based on determined positions of the teats of the milking animal. The arrangement includes a three-dimensional camera directed towards the udder of the milking animal that repeatedly records three-dimensional images of the udder, and a processing unit that repeatedly detects the udder or teats of the milking animal, determines their positions based on the recorded three-dimensional images, automatically determines the shapes of the udder or teats based on the repeatedly recorded three-dimensional images, and automatically calculates a breeding rating based on the determined shapes of the udder or teats of the milking animal.

  • Publication number: 20130180455
    Abstract: A control system for at least one flexible tubular element connected to a cup-shaped member includes a positioning mechanism arranged to hold the cup-shaped member and the tubular element in a parking position in a magazine when the cup-shaped member is not used, and to allow a pull-out motion of the tubular element when the cup-shaped member is moved from the parking position in the magazine to an attaching position on a teat of an animal by a gripping member. The control system further includes a control unit arranged to control the positioning mechanism such that it provides a pull-out motion of the tubular element with a controlled speed when the cup-shaped member is moved from the parking position to the attaching position on a teat of an animal by the gripping member.
