I personally think that robotic milking is the way forward and that to invest in robotic milking is a sound choice and should not cause you financial losses. Quite the opposite in fact, yields should increase, health problem should decrease due to less stress on the cow.
I agree that if you are making such an investment you should, as i am sure any sane person would, do your homework. The results of your homework will more than likely convince you that robots are reliable, safe and cost effective. They are not for everyone however and will not suit every type of farm. Anyone can put a robot in and it will work ok. With this kind of investment it needs to work amazingly. Planning is key. You must get the cow traffic correct. Your dealer should assist you with this.
