Robot Passes Turing Test for Polyculture Gardening

I really like crops. I’m not nice with crops. I’ve accepted this truth and have due to this fact entrusted the lives of the entire crops in my care to robots. These aren’t fancy robots: they’re automated hydroponic methods that deal with water and vitamins and (pretend) daylight, and so they do an incredible job. My crops are nearly actually happier this fashion, and due to this fact I don’t must really feel responsible about my hands-off method. This is very true that there’s now knowledge from roboticist at UC Berkeley to again up the assertion that robotic gardeners can just do pretty much as good of a job as even the most effective human gardeners can. In truth, in some metrics, the robots can do even higher.

In 1950, Alan Turing thought of the query “Can Machines Think?” and proposed a check based mostly on evaluating human vs. machine capability to reply questions. In this paper, we contemplate the query “Can Machines Garden?” based mostly on evaluating human vs. machine capability to have a tendency an actual polyculture backyard.

UC Berkeley has a protracted historical past of robotic gardens, stretching again to a minimum of the early 90s. And (as I’ve skilled) you’ll be able to completely have a tendency a backyard with a robotic. But the true query is that this: Can you usefully have a tendency a backyard with a robotic in a method that’s as efficient as a human tending that very same backyard? Time for some SCIENCE!

AlphaGarden is a mix of a industrial gantry robotic farming system and UC Berkeley’s AlphaGardenSim, which tells the robotic what to do to maximise plant well being and development. The system features a high-resolution digicam and soil moisture sensors for monitoring plant development, and every thing is (principally) fully automated, from seed planting to drip irrigation to pruning. The backyard itself is considerably difficult, because it’s a polyculture backyard (that means of various crops). Polyculture farming mimics how crops develop in nature; its advantages embody pest resilience, decreased fertilization wants, and improved soil well being. But since totally different crops have totally different wants and develop in numerous methods at totally different charges, polyculture farming is extra labor-intensive than monoculture, which is how most large-scale farming occurs.

To check AlphaGarden’s efficiency, the UC Berkeley researchers planted two side-by-side farming plots with the identical seeds on the similar time. There had been 32 crops in complete, together with kale, borage, swiss chard, mustard greens, turnips, arugula, inexperienced lettuce, cilantro, and pink lettuce. Over the course of two months, AlphaGarden tended its plot full time, whereas skilled horticulturalists tended the plot subsequent door. Then, the experiment was repeated, besides that AlphaGarden was allowed to stagger the seed planting to present slower-growing crops a head begin. A human did have to assist the robotic out with pruning every now and then, however simply to comply with the robotic’s instructions when the pruning software couldn’t fairly do what it needed to do.

The outcomes of those checks confirmed that the robotic was capable of sustain with the skilled human by way of each general plant variety and protection. In different phrases, stuff grew simply as effectively when tended by the robotic because it did when tended by knowledgeable human. The largest distinction is that the robotic managed to maintain up whereas utilizing 44 p.c much less water: a number of hundred liters much less over two months.

“AlphaGarden has thus passed the Turing Test for gardening,” the researchers say. They additionally say that “much remains to be done,” principally by bettering the AlphaGardenSim plant development simulator to additional optimize water use, though there are different variables to discover like synthetic gentle sources. The future here’s a little unsure, although—the {hardware} is fairly costly, and human labor is (comparatively) low-cost. Expert human data is just not low-cost, after all. But for these of us who’re very a lot non-experts, I might simply think about mounting some cameras above my backyard and putting in some sensors after which simply following the orders of the simulator about the place and when and the way a lot to water and prune. I’m at all times comfortable to donate my labor to a robotic that is aware of what it’s doing higher than I do.
