"Robots allow the cows to set their own hours, lining up for automated milking five or six times a day — turning the predawn and late-afternoon sessions around which dairy farmers long built their lives into a thing of the past. With transponders around their necks, the cows get individualized service. Lasers scan and map their underbellies, and a computer charts each animal’s 'milking speed,' a critical factor in a 24-hour-a-day operation. The robots also monitor the amount and quality of milk produced, the frequency of visits to the machine, how much each cow has eaten, and even the number of steps each cow has taken per day, which can indicate when she is in heat." This is how I would prefer to be milked, if I had to be milked, I guess.
