I just want to cross-pollinate this project here, it's called "Acorn". It's an Open-Source DIY robot for small scale regenerative farming under development at a small research farm in California. It's the kind of thing one might use if you get old or if you can't be on your land for awhile for some reason. They are not at the point of offering kits yet, but they're asking for support and interested people to join their online community. They are into regenerative ag, but I don't think they're specifically about Permaculture.
