John Fendrick is the owner of a dairy farm. Now on his farm, a robot is milking cows. The cows are standing in line for a turn at the robot. He knows about the progress of the animals by looking at a computer screen. That is all he has to do.

"The door of the milk opens up, they walk in, they get milked. The door opens up, they walk out." The robot does all the work. It uses a laser to find each teat -- the place on the cow where the milk comes out. The robot then cleans the teat and connects a milking tube to it.

The robot also tests the milk. If it finds a problem, it throws the milk away. When the amount of milk coming out of the cow slows, the machine knows to stop, and sends the cow on its way.

John Fendrick says the robots have changed life on a dairy farm. With the robot, Mr Fendrick doesn't even need to be there to watch his cows be milked. He can watch from his telephone. He can learn when each cow was milked and how much she produced. He can also learn if a cow has not been milked for a long time. And he can also turn his attention to other things. He gets about 475 liters of milk a day, and he never has to touch a cow. 

Now milking robots are becoming popular among dairy farmers in the United States, Europe and Australia.
