Patent ID: 7246571

Claim:
A device for determining the expected teat positions of a dairy animal after milking thereof, the dairy animal having a left rear teat, a right rear teat, a left front teat and a right front teat, the device comprising: a position-measuring device for determining the positions of the teats prior to the milking of the dairy animal and for generating individual teat position signals corresponding to the individual teat positions; and a control unit for determining, on the basis of the four teat position signals determined before the milking, a first centre between the left teats, a second centre between the right teats, a third centre between the rear teats and a fourth centre between the front teats, for determining a first plane of symmetry comprising the first and the second centre, and for determining a second plane of symmetry comprising the third and the fourth centre, the planes of symmetry extending at least substantially parallel to the teats.
