What do you imagine the future of farming to look like? The FarmBot team, located along the California coast in San Luis Obispo, is exploring just that. The team has set out to create humanity’s first open-source CNC farming machine to put the power of polycrop farming into the smallest of spaces.
The FarmBot structure fixes directly on top of any standard raised planter box. You can think of it like a 3D printer, but instead of extruding plastic, the tool head deposits seeds, delivers water and rids the box of weeds, all by moving across a gantry. Powered by a Raspberry Pi 3, an Arduino Mega and a motor control shield, the FarmBot brings agricultural automation within the reach of the committed hobbyist.
FarmBot’s interchangeable tooling set is impressive and has been carefully designed so that you may print tools with any hobbyist-level 3D printer.
The universal tool mount features 12 electrical connections, three liquid/gas lines and magnetic coupling. Ready-to-print attachment tools include the seed injection mount, the water nozzle specially designed for efficient watering, and the weed suppression tool which detects and destroys weeds at the root. FarmBot has documented detailed technical specifications of the universal tool mount, to encourage community members to design additional custom mounts that are specific to their particular farming needs.

FarmBot’s drag-and-drop web-based platform allows you to design and build your planter box farm easily. No coding is required; in fact, it has an almost game-like interface. Once your design is complete, the sequence builder and scheduler will help to allocate appropriate care to each plant.
It’s evident from looking at the design structure, documentation, CAD files, and detailed BOM that the creators of the FarmBot took to heart the idea of open source. By selecting off-the-shelf products and tools, they ensured this system is as accessible as possible. I’m really happy to see the Raspberry Pi 3 at the heart of FarmBot and I can’t wait to see how this community grows.
If you’re someone who’s serious about getting a good crop return from your small space, and you’re as mesmerized by FarmBot as I am, there’s still time to place a pre-order to receive one of the first batches ready to ship in February!
