The machine allows his 140 cattle to effectively milk themselves as often as they want to.
Once inside, the animals receive a measure of feed, have their udders washed and sterilised by a robot arm and computer-guided suction cups attach themselves to their teats.
Their milk is tested for impurities before a gate opens, allowing them to walk back to the field.
While Mr Gibson initially had to coax his cattle into the milking booth, he now claims animals wait in line and some have doubled their yield.
