anyone in touch with https://pixelfarming.eu/ ? It’s in Dutch, so that may be hard to digest.
Basically, it’s a research center that has the same idea: create a robot to automate organic farming. I think I once saugh a pixture of a farmbot on wheels.
They are putting a lot of effort in a portal where customers can rent farming land and the service to grow meals on that land. They’re launching a new robot soon. very exciting!
I’m also working on a robot in my spare time. Imagine a robot lawnmower had babies with a rototiller 
I’ve shared progress in this thread:
Oops, 't has been a year! I’ll post some pictures of the current prototype as soon as we have sunlight…
