Seven farms in the U.S. are experimenting with a robotic milking system, which is billed as a tool for the salvation of small, family-owned dairy farms.
Cows walk up to the milking station and munch a little grain. Meanwhile, a robot's moving parts prod at the animals' udders.
While many farms have computerized milking systems, a farmhand is still needed to herd the cows and guide and clean the machinery.
If a mechanical problem arises, the robot would call a farmhand's cell phone.
