A robotic arm maneuvers a teat preparation cup and executes instructions from a robotic arm controller. The controller comprises an interface, a memory, and a processor. The processor instructs the sensor to perform a first scan. If the first scan discovers a first set of teats, the processor moves the robotic arm a first distance and instructs the sensor to perform a second scan. If the second scan discovers a second set of teats, the processor moves the robotic arm to a location under the first teat, and instructs the sensor to perform a third scan. The processor determines if the third scan discovers a third set of teats. If each of the first set, second set, and third set of discovered teats comprises the first teat, the processor instructs the robotic arm to attach the preparation cup to the first teat.

A method for milking a dairy animal using a milking device with a measuring device for a milk parameter, the method including identifying the dairy animal, determining a milking interval, attaching milking cups to the dairy animal, calculating, according to a first formula, an expected value for the milk parameter, milking the dairy animal, and detaching the milking cup when a first detachment criterion has been met. During the milking step and/or during the detaching step, use is made of the expected value of the milk parameter without determining the actual value of the milk parameter. The actual value is the value of the milk parameter if the milking takes place using a second detachment criterion which is stricter than the first detachment criterion. The method further includes measuring the actual value of the milk parameter for the present milking and updating the first formula.

A preparation robot, a teat preparation arrangement, and a method of preparing teats are disclosed. The preparation robot includes a base, a robot arm arrangement connected to and movable in relation to the base, the robot arm arrangement including an outer robot arm member, a first teat-preparing cup, and a second teat-preparing cup, each including an inner space for receiving a respective one of the teats. The first teat-preparing cup is attached to the outer robot arm member to be immovable in relation to the outer robot arm member during operation of the preparation robot. The second teat-preparing cup is detachable from the outer robot arm member to be movable in relation to the outer robot arm member during at least a part of the operation of the preparation robot.

An automatic milking system controlled by receiving a parameter representing a measured flow of milk extracted from at least one teat of an udder of an animal being milked in a milking operation via at least one teatcup of the milking system, wherein the milking system is controlled to stop the milking operation based on a first criterion indicating that the flow has reached a decline phase, and a second criterion indicating that the flow decreases faster than a threshold slope, the milking operation being stopped in response to fulfillment of the second criterion on or after a point in time when the first criterion has been fulfilled. As a result, a particular amount of milk is left in the udder of the animal, irrespective of an overall milking time for the animal.

An offset for a first milking tool in a tool carrier of an automatic milking machine is determined as a spatial vector between a tool reference position (TRP) and an estimated actual position (TAP) of the milking tool. A three-dimensional image data is registered that represents a teat (T) during attachment to and/or detachment from the milking tool. The image data is processed by searching, within a search zone, for a predefined part (MP) of the teat (T) while the teat (T) is attached to the milking tool. Provided that the predefined part (MP) fulfills a measurement criterion, a distance (d.sub.off) is calculated between a specific point of the predefined part (MP) and the tool reference position (TRP). The offset is then determined based on the calculated distance (d.sub.off).

A method for use with a multibody system includes two body sections assembled via a joint, one of the body sections including a camera which is moveable between a first position and a second position, includes detecting a reference object with the camera situated in the first position, determining a reference value of the reference object, requesting movement of the camera from the first position into the second position, initiating movement of the camera from the first position towards the second position, while iteratively sampling image of the reference object, determining a current object value of the reference object, based on the sampled image, matching the reference value with the current object value, and determining successfulness of the camera movement, based on the matching.

A milking device for milking of a dairy animal with teats includes a control unit, a milking device including milking cups, a robot arm to attach the milking cups to the teats of the dairy animal, a teat-detecting device to determine positions of the teats, including an outer optically permeable component, such as a lens or cover plate, and a cleaning device to clean the optically permeable component. The cleaning device is provided with a cleaning liquid supply and an application device to apply the cleaning liquid to the optically permeable component. The milking device includes a spraying device for spraying a teat-treating liquid on the teats. The application device is configured to apply cleaning liquid to the optically permeable component at least while the spraying device sprays the teat-treating liquid. As a result thereof, adhesion of the often sticky teat-treating liquid to the optically permeable component is efficiently counteracted.

Methods and apparatus for milking a milk-producing animal, in particular a cow, that set a target milk quantity which is lower than a possible expected milk quantity, carry out the milking process, determine the milked quantity and compares the milked quantity with the target milk quantity, and terminate milking when the milked quantity corresponds substantially to the target milk quantity.
