Podcast Notes Playlist: Business Episode #472: FarmBot and the Vision of a Distributed Food Future
Key Takeaways
- FarmBot is a robotic farmer for your garden, designed to take care of your garden by performing functions such as planting seeds, watering, weeding, and monitoring
- Simply being open source is not enough. For a project to be genuinely useful, it must also have extensive, clear documentation and use open, affordable file formats
- Today, the vast majority of food that people eat is grown very far away and in ways that is not great for the food or environment
- We have very little control over the food production system, which is vital to our existence
- Let us get back to the smaller scale, more diverse polycrop system of food production; many follow-on benefits will result
- Building a resilient alternative to industrial food systems (which often rely on single-crop farming) reduces single points of failure along vulnerable supply chains
- The more that we can distribute the food system and bring it closer to the end-eater, the more robust our overall food system becomes

On this episode of Crazy Wisdom, Stewart Alsop speaks with Rory Aronson, CEO of FarmBot, about how his open-source hardware project is transforming home gardening into a more automated and accessible practice. Rory explains how FarmBot works—essentially as a CNC machine for your garden—covering its evolution from Arduino-based electronics to custom boards, the challenges of integrating hardware and software, and the role of closed-loop feedback systems to prevent errors. They explore solarpunk visions of distributed food systems, discuss the importance of “useful source” documentation in open-source hardware, and imagine a future where growing food is as easy as running a dishwasher.

Key Insights
- Rory Aronson shares how FarmBot began as a DIY project built on Arduino and Raspberry Pi, leveraging the open-source 3D printing ecosystem to prototype quickly. Over time, they transitioned to custom circuit boards to meet the specific demands of automating gardening tasks like seed planting, watering, and weeding, highlighting the tradeoffs between speed to market and long-term hardware optimization.
- The conversation unpacks the complexity of FarmBot’s “stack,” which integrates cloud-based software, a web app, a message broker, a Raspberry Pi running a custom OS, and firmware on both Arduino and auxiliary chips for real-time feedback. This layered approach is crucial for precision in an unpredictable outdoor environment where mechanical errors could damage growing plants.
- Aronson emphasizes that being open source isn’t enough; to be genuinely useful, projects must provide extensive, accessible documentation and export files in open, affordable formats. Without this, open source risks being a hollow promise for most users, especially in hardware where barriers to modification are higher.
- They explore the solarpunk potential of FarmBot, imagining a future where growing food at home is as effortless as using a washing machine. By turning gardening into an automated process, FarmBot enables people to produce fresh vegetables without needing expertise, offering resilience against industrial food systems reliant on monoculture and long supply chains.
- Aronson points out that while FarmBot isn’t designed for industrial agriculture, its modularity allows it to support niche commercial use cases, like automating seedling production in cleanroom environments. This adaptability reflects the broader vision of empowering both individuals and small operations with accessible automation tools.
- The episode highlights user creativity enabled by FarmBot’s open hardware, including custom tools like side-mounted mirrors for alternative camera angles and pneumatic grippers for harvesting. These community-driven innovations showcase the platform’s flexibility and the value of encouraging experimentation.
- Finally, Aronson sees great potential for integrating AI, particularly vision systems and multimodal LLMs, to make FarmBot smarter—detecting pests, diagnosing plant health, and even planning gardens tailored to user goals like nutrient needs or event timelines, moving closer to a truly intelligent gardening companion.
