An algorithm to attach and release teat cups using, an articulated robot manipulator with a 4 degrees of freedom, has been developed. For successful teat cup attachment the articulated robot manipulator must be able to adjust to subtle angles and various movements. The cups follow a Lissajous figure on the XY horizontal plane. A local sensor determines the center of the teat, and the end effector raises the cup to the teat. A vacuum holds the cup in place. Field trials for the milking robot system were done with two milking cows. The “Global Positioning Arm” (GPA) was not sufficiently accurate to allow only recorded teat positions related to body to be used for attachment but are generally good enough for the initial approach to the teat. Local sensor could then detect error and allow for centering the cup on the teat. The GPA always maintains contact with the body of the cow, enables the automatic milking unit to maintain a relative position and smoothly follow teat movements for easy automatic milking. The automatic attachment of the teat cups was achieved in approximately 60 [sec]. Teat cup vacuum decreased from 48 [kPa] to 20 [kPa] in less than 0.2 [sec] after attachment, which means that attachment required minimal air inflow. These results showed that the milking robot is a practical milking system.
