Now we have this:
Roboticists at the University of Sydney designed and tested a remote-controlled robot that can herd cattle. The advantage of the robot is that it moves slowly, permitting the cattle to move at a reduced pace and thus decrease the likelihood of injury through overexertion. Human cowboys in 4-wheel drive vehicles, in contrast, tend to rush and occasionally hit cattle while herding them.Video here.
I see cloned dairy cattle being herded by robots into robotic dairy sheds. That's all possible right now.
