Robotic Farming in your Backyard Garden

The FarmBot Genesis is a robot that moves around a small garden bed using tracks on the sides of the box. It can plant seeds, water plants, and perform other basic gardening tasks. 

A company called FarmBot is now selling robots designed to weed, water and grow fresh produce for you. This is an open-source project which allows you to buy a robot gardener or build your own!  

The first version of the FarmBot — called the FarmBot Genesis — is designed to work in a raised garden bed or garden box.

The robot itself moves around using tracks on the sides of the box, and it works in three dimensions. So it can go left to right; forward and backwards; and up and down. If you've ever seen a 3D printer, it moves around in a similar way. But instead of squirting out plastic, the FarmBot sows seeds, waters plants and gets rid of weeds — using different attachments for each job. It can grab different tools, depending on the task at hand.

This robot has been in the works for a few years — but you can now actually buy one now. The California company behind the robot has started taking pre-orders, which cost about $4,000 Cdn ($3060). And in the last month, FarmBot has raised about $1 million to start manufacturing kits.

FarmBot seems to be designed for people who want to grow their own produce, but aren't terribly interested in the actual work of gardening to get that produce. 

Part of the idea behind FarmBot is that it's designed to work in relatively small gardens. If you pre-order a kit, you'll get standard tracks that are three metres long. The robot is designed to work on raised beds that are about about 1.5 by three metres. So small spaces — backyard farming, rooftop farming or small greenhouses.

The team behind FarmBot says one of their goals is scalability — so it can work in larger or smaller areas, depending on your needs.

One of the most interesting aspects of this project is that it applies the same kinds of automation we see in large-scale agriculture, but on a much smaller scale.

The source code for all the software, and the blueprints for all the parts, are public and freely available — so you can modify or tweak it.

"If you want to use pesticides, you can do that. If you don't, you don't have to. If you want to water your plants in a certain way — maybe with mister nozzles, versus a shower nozzle, you can do that," said the FarmBot founder Rory Aronson.

"You can measure the pH, measure the temperature, measure whatever it is that you want to do, so you have complete control and agency over how you grow your food."

FarmBot founder Rory Aronson says part of the appeal of the system is that it's highly customizable. 

He sees the FarmBot not so much as a product, but as a platform that can be customized as you see fit.

How can the FarmBot tend to different plants?

It taps into an earlier project called OpenFarm, which is an open-source crop database. You can think of it as sort of like Wikipedia, but for farming and gardening knowledge. For each crop, there are details about how much sun and water it needs, what type of soil is best, row spacing, and so on.

Because that database is designed to be read by both humans and machines, the FarmBot can download crop information and use it to tend a garden — giving each plant the right amount of water, testing the pH of the soil, that sort of thing.

The FarmBot is controlled by a web app, which you can use to manually control the robot. Or you can set it up on a schedule.

I don't have a FarmBot at home, but I have played with the app. If you remember the online game FarmVille, it's a bit like that. You lay out your crops, water your plants, and weed the garden. But unlike FarmVille, you're doing it with real plants.

If you take the DIY approach, there are full instructions available online.

If the FarmBot takes off, it will be a really great way to teach kids not only about electronics and coding, but also about farming.
