This is pretty cool. Any plans for expanding it to non raised bed gardens… What about a tractor that follows a burred guide cable? You might need more memory than a raspberry has but that can be easily resolved. I think something like this may even have commercial applications. the only limitations it might have are on tall plants like corn or sunflowers.
just my 2 cents worth… I am going to keep an eye on this…Its out of my price range right now but maybe it will be better in a few years… Thanks for keeping it open source…
