After reading this, and being fairly familiar with the automated milking
process, a few questions of this robotic process popped into my head..... and I
was wondering if you maybe knew some of the answers. For the automated process,
milking is limited mainly by the dairy farmers ability to manage overhead costs
of equipment (eg, holding pens, refrigerated tanks, auxiliary generators for
poweroutages, etc) so with cost set aside (and I am sure a system like this is
not cheap) I'm wondering, can the robotic system keep up on the production for a
large number of head? What is the output limitations? Is 60 head the max?

Secondly, since this set up must be so much more costly, and aside from being
interesting and really cool, I am wondering what the real advantages are from a
system being totally robotic compared to just being automatic? Is there is real
benefit to the beast, or is the saving of labour costs that great? I know many
dairy farms with large number of head, that still operate as a family business,
so I'm guessing it just can't be the labour costs, I must be missing something.

Thirdly, I also assume (even though the cows are under their own "freewill") since there is a monitor system in place identifying each beast, there also must be a warning system in place for cows that haven't wandered in of their own free will. How long are they left to their own demise? Knowing fully that serious complications can take place if they are not milked regularly, I have to assume they are not let that long. I have to wonder how much human intervention is needed to prompt those that do not show up for release. Or is the process so truly Pavlovian that there is little need for human prodding (pun intended)?
