thanks for your response. I am sorry, I did not specified correctly what I meant. I like gardening and I like when the garden is not only about straight fields but like a something what fit to a landscape. I understand that the farmbot can be impemented also in such fields but would be probably just more expensive to do so. As the rails could be mounted on all the fields and then maybe moving manually day by day the top of the farmbot would be possible. I just do not like the idea when there will be a big straight field farmed by the bot. From the logical point of view when somebody wants to grow as much food as possible for himselve, there is nothing bad on the idea to have a big straight field. But like I said before, I like the gardens where it fit to a various lendscape.
I hope I explained my intention a bit better then before and also I wanted to say sorry for my english. I hope it is readable for others.
