TX Harvesters from advanced.farm

 

 

it’s a misty morning near Salinas, California and the advanced.farm TX harvester—a lightweight, driverless tractor covered in canvas—is picking strawberries. Like a dot-matrix printer moving along a page, the harvester’s robotic hands move back and forth along the beds, scanning for signs of red. When it identifies a ripe berry, it dives down, gently plucks it from the plant, and places it in a crate.

At the same time, a crew of about two dozen farmworkers is also harvesting strawberries just a few hundred feet away, on an adjacent farm. As an energetic song blasts from a parked vehicle, the men and women stoop to pick berries straight into plastic clamshells that they tile, side-by-side, into cardboard trays. Once their trays are full, the workers take them back to one of several sorting tables spread out along the access road (to allow for social distancing). It’s clear by the speed at which they’re walking—and in some cases even running—to drop off each box that these men and women are getting paid by the piece.

I’ve trudged through the muddy, irrigated fields to watch both forms of harvest with Kyle Cobb, advanced.farm’s youthful, clean-cut CEO. The company was the first to mechanically harvest strawberries for commercial sales last year, and had raised just under $10 million by June 2020, including a $7.5 million Series A round in 2019. After building a robot that cleaned solar panels, Cobb and his team dove into agriculture, where they hope to put an end to the notoriously grueling, repetitive work of harvesting strawberries.

If things go as planned, and advanced.farm is able to scale up over the next several years, Cobb says, “You’d see the same crew, but instead of it being this big, you’d see about half the size . . . and they wouldn’t be doing the traditional picking like this. They’d be doing a combination of sorting and packing in a very comfortable ergonomic set up.”

Today, instead of the fleet of three or four harvesters that are typically picking berries, the TX is in the field prototyping, gathering data to be used by the company’s team of engineers at their office three hours north, in Davis. Prototyping is slow, exacting work, and the machine is accompanied by field operations manager Jorge Cava, who carries a tablet and watches patiently as the harvester moves along the rows, learning thousands of iterations of berry, stem, and leaf. “We should get several hundred more hours testing on it,” said Cobb, before it goes back into the field.

Compared to the hustle taking place on the next farm over, it’s a pretty low-key scene—boring even, to the untrained eye. And yet, Cobb, Cava, and others working to automate the harvest have been in the midst of their own hustle over the last few years. Now, the pandemic has ratcheted up the pressure.

For farmers considering investing in the automation, Cobb tells me in the field, he sees the pandemic as one of several factors that will breaks the camel’s back. “It’s the rising cost [of labor], it’s the already-dwindling supply, the aging of the workforce, the hard work. Add in a health pandemic that further limits the supply and complicates your daily logistics, and automated harvest starts to sound really nice,” he said. Hazardous conditions caused by this year’s wildfires may also be a factor, although they haven’t stopped many crews from harvesting this fall.

It’s not just growers who may soon embrace the technology. In California, most of the counties with the highest rates of infections are in the Central Valley, the state’s most productive agricultural region, and home to hundreds of thousands of farmworkers. And as farmworker communities around the country battle a growing number of coronavirus outbreaks, illnesses, and deaths, the discussion of automation across the food production spectrum has grown in the public arena as well. If the people doing the work on farms are getting sick, the logic goes, why not just replace them with machines?

The transition for the companies isn’t going to be fast or easy: Cobb estimates that it will likely take five to 10 years before it’s really complete.

“We’re working as hard as we can,” he said, as he details the many challenges companies like his face in the process to get the machines out in the field, working as fast as human pickers. For a good part of the summer, for instance, the strawberry plant’s leaves grow so large that they essentially block the harvester’s vision from above. And strawberry breeders have so many other priorities, that it could be a while before they start breeding plants that make it easier for the harvesters to do their job.

Of course if advanced.farm—or one of the other companies in its lane—succeeds, the shift won’t be easy for farmworkers either, nor for farm-centric communities such as Salinas, Watsonville, and Oxnard.

The strawberry industry employs about 55,000 people in on-farm jobs on an estimated 38,000 acres in California—making it one of the state’s more labor-intensive crops. And if automation successfully cuts that number in half it could mean the loss of over 27,000 jobs in that slice of the produce sector alone.

A Ripe Moment for Automation on Farms

For Sébastien Boyer, the shift toward increased automation in farming is an inevitable one. Boyer is the CEO of Farmwise, a company that launched its first autonomous weeding robots in early 2019, and has grown quickly in the year and a half since then.

FarmWise went from having a small handful of weeding machines in 2019 to 20 of them in 2020. It also scaled out from a startup in a garage in San Francisco to a 700,000-square-foot shop and headquarters in Salinas. And Boyer says he has seen an increase in interest from farms in California and Arizona.

“We see a kind of short-term positive shock in the attractiveness of what we do. But we are also seeing increased discussion around automation,” Boyer told me in his thick French accent. “By and large, what I think is going to happen during the crisis is a faster push for things that makes the overall supply chain less reliant on the uncertainty of manual work being done in the fields.”

Advanced.farm’s Cobb echoed this sentiment. “There are always early adopters, and they have been ahead of this trend for all kinds of reasons,” he said. “But now that second wave of people, the mass adoption . . . I think they’re moving faster. They’ve changed their mindset faster than you otherwise would have expected.”

Emily Reisman is an assistant professor in the Department of Environment and Sustainability at the University of Buffalo and a recent transplant from the University of California, Santa Cruz. As part of a larger effort to document and study the agtech industry with a group of other researchers, including U.C. Santa Cruz’s Julie Guthman, she has been attending agtech events—which have moved on online but not slowed down—since before the pandemic began.

“I think it’s unlikely that COVID will dramatically accelerate the development timelines of these companies, especially for mechanical devices,” said Reisman. “But this moment might allow certain technologies to gain legitimacy and potentially additional financial backing, institutional support, or broader public acceptance.”

Reisman is also concerned that COVID is being used as a way to depoliticize technology that displaces workers. She has spent the last few years studying the almond industry, where automation already allows for near-instant harvest thanks to mechanical tree shakers that can remove an entire tree full of nuts in around a minute. On those farms, the number of people needed per acre is minuscule.

“I found that the crop’s high level of automation is part of what makes it so attractive to financiers looking at land as an investment. Low labor means low risk,” she said. “So, I think automation is attractive not only to farmers or technology companies, but also people who are interested in land as a financial asset.”

Rather than selling their equipment, both Farmwise and advanced.farm contract with farmers to pay for the machines’ services—which allows the companies to send fleets of weeders and harvesters around the area.

“I found that [almonds’] high level of automation is part of what makes it so attractive to financiers looking at land as an investment. Low labor means low risk.”

And with new overtime laws for farmworkers going into effect in 2022, Cobb says the investment in automation is “more of a hedge for future cost inflation rather than a significant cost reduction.”

Indeed, automated harvesting will potentially do away with the limitations of the workday. It’s not typically safe to employ people to work on farms at night—but machines like the TX harvester don’t care about light or temperature, nor do they have circadian rhythms; they can conceivably run for 24 hours if needed.

“It’s filling the gap in two ways. One is just by supplying machines that can pick instead of humans, and two, improving quality of work for the humans who are left so that more people are attracted to the line of work than are today,” said Cobb, who envisions a transformed industry unburdened by the kinds of repetitive, body-ruining work that is so common in today’s fields.

Better Jobs—and Fewer Jobs? 

When I spoke with Farmwise’s Boyer in April, right after the coronavirus hit, he told me his company was in a rare position to be hiring several people as they ramped up their customer base. “We’re paying significantly more than the average wage that fieldworkers make today. And that’s because we’re going to make every one of those workers drastically more productive than if we were asking them to do this work manually,” he said.

Jaime Eltit, Farmwise’s commercial operations manager, says the new, better-paying jobs created by companies like his are an important response to the farm world’s “shrinking and deteriorating labor force.”

“Probably the youngest people that you see out there right now are around my age,” said Eltit, who is in his 30s. “But the generation below them, those kids aren’t going out into the fields. This kind of work is hard; it’s not really desirable. And so there are going to be less people, but [a small number of] more skilled people doing the job of others.” And companies like Farmwise are “replacing the jobs at the bottom,” such as thinning lettuce, weeding, and harvesting, he adds.

In fact, nearly everyone I spoke to in the agtech industry preferred to focus on the “better jobs” aspect of the coming shift. When I asked Cobb about the fact that the future he and others envision could involve fewer jobs, he cautioned me to be careful about that phrase.

“Right now, one of the ways [farms] bring people to bridge the gap is through H-2A visas and immigration,” he said. “My hunch is that that’s always going to be a necessary part of the equation. But I think that we’re going to see less need for that type of solution. But I don’t think [automation] is going to take a bunch of domestic jobs.”

At Andrew and Williamson Fresh Produce, a large, multi-farm grower-shipper operation that works with advanced.farm, district manager Matt Conroy shares this sentiment. He points to automation as a way to fill what he says is a “10­–20 percent gap in the workforce,” but adds that “our goal is never going to be to get rid of people.”

“At the end of the day, certain jobs may fall to automation. The goal is not to have that happen. But there’s always an uncomfortable reality in there.”

A few years back, Andrew and Williamson developed the brand Good Farmsin partnership with Costco and the Equitable Food Initiative, a public-private partnership aimed at improving the lives of farmworkers. At its eight Good Farms locations, the company says it includes all its workers in planning meetings, employs them year-round, and provides benefits, among other things. And in an industry known for anonymous disregard at best, and wage theft and sexual harassment at worst, these efforts stand out.

And yet Conroy admits that, “at the end of the day, certain jobs may fall to automation. The goal is not to have that happen. But there’s always an uncomfortable reality in there. It’s like the photo booth people—that job went away when everybody went digital.”

Advanced.farm is the fourth robotics company Conroy has tried working with, and he likes that Cobb and his team are interested in grower feedback, rather than approaching automation purely as a technical problem. And he hopes some of Good Farms’ workers will be able to train to run the automated harvesters, a previously unheard of opportunity in a field that generally offers no opportunity to advance. “It’s about providing more skills to this person now and helping them be marketable in the future, so they can go outside of the scope of just picking from aisle to aisle,” Conroy told me.

Of course, while learning to operate the machine on the farm is one thing, really getting trained in the intricacies of the machinery would require that a worker and their family could relocate to Davis for several months—and he said finding that person could be difficult.

There has also been an effort to provide a pathway for the children of farmworkers to work in the agtech sector. In 2018, produce giant Taylor Farms invested in two centers, including one in Salinas, where existing workers can learn programming, engineering, and machine operation. And the Western Growers Center for Innovation and Technology—a Salinas agtech incubator—has a partnership with nearby Hartnell community college, where the children of farmworkers have been recruited since 2014 to train for computer science degrees. The idea is to provide a path toward a career in tech without having to leave their families behind.

That promise was one of the things that appealed to Eduardo*, a young man who went through the Hartnell program a few years back. After moving with his four siblings at age 10 from Oaxaca to the U.S. to join his parents, Eduardo (whose name has been changed to protect his identity) spent several years working the fields alongside his family—“cleaning lettuce, cutting onions, stuff like that.” He was good at math and got into the fast-tracked computer science program at Hartnell, but finding a job near his family hasn’t proved possible yet.

His first year out of school, Eduardo took an internship for a large ride-share company, learning it was in San Francisco just a few days before it started. Then, the internship turned into a full-time job, and he chose to stay on to learn what he could. He hoped to find work in agtech, but he wasn’t optimistic.

“A lot of my friends are jobless,” said Eduardo. “They’re still looking for a job a year or two after graduating.

When we spoke last fall, he was eating nearly all his meals in the company cafeteria, living in a surprisingly affordable room with other young tech workers an hour outside of the city, and sending money home to his family—a lifestyle entirely different from most of the other tech workers in San Francisco.

“It’s something that I can connect back to my parents,” he added about the prospect of working in agtech. “My dad doesn’t trust getting into a random person’s car. But if I build something for ag, he would trust it.”

Community Impact

Armando Elenes, a farmworker organizer and secretary treasurer of the United Farmworkers (UFW) is skeptical. “They’ve been talking about bringing robots into the field for over a decade,” he said. “I’ll believe it when I see it.” This year, protecting workers from the impacts of the pandemic—and expanding the union’s base, in part so that they have better access to healthcare—are much more pressing issues, said Elenes.

But Maria Cardenas disagrees. The executive director of Santa Cruz Community Ventures, and the founder of Undocufund Monterey Bay, was also neck-deep in her work to support undocumented farmworkers impacted by the pandemic when we spoke. She sees the move toward automation as inevitable, and potentially destructive. “Oh, it’s coming,” she told me. “I mean if you look at the millions that are being invested in things like identifying the right strawberry, those millions are not going to go to waste. It’s coming!”

In Salinas, as in other agricultural regions of California, Cardenas points to the fact that a whole generation of people have been working seasonal, high-skilled, low-wage jobs in the fields for two to three decades without benefits or any increases in pay. Most domestic farmworkers haven’t had access to much education in the last decade, and in recent years the existing population has been joined by a large number of migrants from Indigenous communities who speak neither Spanish nor English.

“Where do they go when these jobs are taken away? There are some young people, but a lot of them are getting close to retirement age, and they have no savings,” said Cardenas. “The employers in ag haven’t really invested in the workforce, and instead treat them as a piece of machinery in the fields.”

In that sense, it’s not surprising that a system that seeks to constantly replace its machinery with a more efficient model would be doing so with human workers as well. But Cardenas adds that most of the farmworkers she and her staff engage with are too mired in the work it takes to survive right now to track the progress of automation—let alone mount a response.

“[In Salinas,] they’re in households earning less than $50,000 a year living in a community that takes $94,000 to be okay. So, in many ways, their ability to work is subsidized by community programs and rental assistance,” she said. “And also by informal networks. The family takes care of the kids. You rotate. Or somebody is working in lettuce so they bring lettuce home and somebody is working berries and they bring berries home.”

Cardenas sees the value of a response from a union or a community organization, but she hasn’t seen one yet. And while the industry points to the opportunity for better jobs, she’s skeptical about the math, especially because a more efficient harvest won’t likely mean more money for the growers who pay the workers.

“All that does is lower your price per pound, with berries in particular. I don’t think a worker who is now running a machine is going to earn so much more . . . to make up for the lost household wages when three people are let go,” she said.

And yet, like many in the industry, Cardenas believes it’s likely that the pandemic will speed up the adoption of automation technology in the fields.

COVID has already made life difficult for farmworkers in many ways. “You have a political environment that makes it unsafe for workers to feel like they can get tested or get support. You have overcrowded conditions that makes it hard to isolate,” she said. “And poverty wages, which means that they can’t afford to not work—or access health care. All of that combined is a tsunami, quite frankly. And all of that combined in households that are already living in fear.”

Add the demand for produce outside the U.S. and consumer concerns about the stability of the food supply, and the drive to produce will likely take priority over other changes, she says.

“Even if the workers are sick, growers will still tend to want to produce. So, I don’t see the time allotted to change the industry,” Cardenas said. “But it will impact the agriculture communities where these workers are living. And the real strain will be felt by cities, which are facing tremendous deficits, and social safety net programs and nonprofits, which are also facing tremendous deficits.”

Getting Out in Front

Samir Doshi, a Race and Technology Fellow at Stanford University, is also concerned about the potential impacts of automation on Latinx immigrant communities in California and he’s engineering a plan to get out ahead of what could be an enormous wave of change.

Doshi did his doctoral research on developing regenerative economies for coal mining communities in Appalachia, and sees potential parallels with agriculture. When faced with questions around safety of miners, the companies turned to automation rather than creating safer jobs, says Doshi.

When faced with questions around safety of miners, mining companies turned to automation rather than creating safer jobs. 

“It did make mining much more efficient; it saved a number of costs. And you had mining happening at all times of the day. It basically extracted the value of that industry completely for the owners and operators. You saw a huge drop in employment, and for a lot of mining communities, whether it’s in Appalachia, New Mexico, or other areas, there was no alternative economic pathway for a lot of those communities,” said Doshi. “They didn’t get other jobs within the industry, which is what is being promised in agtech. And they did not move up the career ladder.”

Instead, the mining companies, which tended to be based outside the communities where the mining takes place, have all moved their own higher-level employees in to run the machines.

Doshi is concerned about this pattern being replicated within agriculture, where immigrant communities play a larger role. “The consequences aren’t just people being put out of jobs. It’s people being pushed out of their homes, their country, their communities,” he said. “It is definitely possible to have dramatically cascading effects on communities and regions for what automation does.”

He has been tracking the rise of agtech outside the U.S., where it’s being funded by many of the same large foundations that have brought genetic engineering to the developed world. Doshi believes that, globally, investment in agtech is “going to be as pervasive as biotechnology,” using a similar narrative of food security and efficiency.

Doshi has spent time studying healthcare, education, and other industries that have been radically changed by technology, and hopes to bring a range of stakeholders—from industry representative to academic institutions, foundations, investors, and grassroots community organizers—into a single conversation about how to take workers and communities into account while adopting tech solutions in agriculture. The ultimate goal is a set of principles, or a code of conduct that can help guide the industry.

Doshi is looking toward other efforts like UNICEF’s innovation principles and the Digital Impact Alliance, which has created principles for digital developmentthat helped shape investment in the space.

“I’m not trying to be predictive. We’re trying to be considerate and strategic about how to take care of our communities, how to take care of our food systems, and how do we look at sustainability and value across both of those domains over time,” said Doshi, who has also worked as a Senior Scientist at USAID, and for the San Mateo Food System Alliance and California Alliance for Family Farms (CAFF) in recent years. The goal, he says, isn’t to stop technology in its tracks, but to widen the conversation to include workers and smaller farmers who don’t benefit from the same kinds of tech.

“There are many technologies that can genuinely benefit small-scale, medium-scale family farms,” he said. “And if we can even the playing field in terms of the utility and efficacy and equity within these technologies and distribute the value that’s provided so that it’s not just large-scale investment into large scale applications that then [only] benefits industrial farming and agriculture.”

While the pandemic has slowed down Doshi’s process, he hopes to convene digital conversations about what it would take to develop a code of ethics in agtech—and get buy-in from investors and governments, using mechanisms like the Digital Impact Alliance, the World Economic Forum and other convening agencies and coalitions.

 

Farmworkers pick strawberries in 2019. (USDA photo by Lance Cheung)

A Monocrop of Movement 

It’s hard to talk about replacing workers with automation without looking squarely at the very real physical cost of farm labor.

Flavio Carnejo, a family physician who works with strawberry and raspberry pickers in central California’s Pajaro Valley, described it well in a TEDxFruitvale presentation in 2011, in which he lists the types of pain, swelling, and spasms that occur in the worker’s wrists, shoulders, and backs, as well as longer-term effects, like compression in the sciatic nerve, degenerative joint disease, and arthritis, that farmworkers endure years before most other people do.

“Strawberries are picked stooped over, and our bodies are just not designed to do that for so long. You don’t have to be a physical therapist to realize there’s going to be a tremendous amount of damage that’s going to happen to the physical body,” he said. “You touch the back of some farmworkers and they feel like they have rods running up their backs—even years later.”

But it’s not clear that replacing people on the land is the best—or only—way to avoid these problems. And it’s hard not to compare the environmental challenges that come up in agricultural monocrops with the monocrop of movement we see in today’s produce fields. While science points to a diversity of crops as fundamentally better for the environment—it means fewer pests, healthier soil, and cleaner water, for instance—it’s also clear that a diversity of tasks and movement has benefits the human body and brain.

“There’s a lack of acknowledgment that the repetitiveness of the motion, which causes physical injuries and then allows for robotic interventions, is really symptomatic of the plantation structure of current agricultural practices,” said Emily Reisman. “Everyone acknowledges that this model is problematic ecologically and socially. And yet somehow we have no choice but to use the plantation to overcome it.”

If the industry weren’t trying to replicate what has been done in factories and other industrial settings on farms, she adds, they may find themselves asking, “what would it take to make economically viable agricultural work that fosters more diversity, or is more intellectually and creatively fulfilling? What would it take to make farm work a pursuit that enriches every life it touches?”

“We know that so many people are desperate for some kind of physical connection to the Earth—not only for their own health, but their psychological well-being, and a sense of place and purpose,” she adds.

Meanwhile, Eduardo, the son of farmworkers, is holding out hope that he’ll get to help make Salinas a place where he and his peers in tech can pursue their own sense of purpose. And if automation becomes the norm on Central Valley farms, it won’t be all that different than the changes that drove his parents to the U.S. in the first place.

“Immigrants—we don’t do one thing,” he said. “Farm labor is obviously a huge thing we do. But there are a lot of immigrants that work in restaurants and lot of different parts of the world. And we might just have to adapt.”

미래의 농업노동자는 기술과 강철로 만들어질 것이다. 로봇이 농업노동자보다 더 일을 잘하고, 빠르며, 저렴하게딸기를 수확할 수 있을까?



인간과 기계 모두 한 포기당 10초 걸린다. 그들은 잎 사이에서 잘 익은 딸기를 찾아서 줄기에서 조심스럽게 비틀어 따서 플라스틱 상자에 넣어야 한다. 과일이 못쓰게 되기 전에 반복,반복, 반복. 



어느 2월의 오후, 그들은 축구장 454개 크기의 농장에서 1200평의 작업을 수행했다.  12명의 일꾼이 몇 세기 동안 해 온 방식으로 수확한다. 그리고 엔지니어들은 로봇이 이르면 다음해까지 그들 대부분을 대체할 수 있다고 한다.


여기 플로리다에 노동력 부족을 완화시키고 먹을거리 생산비를 줄이겠다고 약속하는 농작업의 미래가 도래했다고 말이다. behind Harv는 자동화 기업 Harvest CROO Robotics의 최신 모델명이다.


Harv는  오랫동안 엔지니어들을 괴렵혔던 과제인 물크러지고 으깨지는 상품을 모으는 방식을 자동화하려는 전국적 성화의 최첨단에 서 있다.  


부드러운 촉감을 지닌 로봇을 설계하는 일이 미국의 농장을 자동화하는 데 가장 기술적인 장애물 가운데 하나이다. 재배자는 줄어들고 있는 노동력 때문에 그것 없이는 합리적 가격의 과일과 채소는 위기에 처하게 된다고 이야기한다. 


“노동력은 계속 줄어들고 있다”고 3세대 딸기 농민인 Gary Wishnatzki 씨는 말한다.  “우리가 자동화로 이를 해결하지 못하면, 신선한 과일과 채소는 일반인에게 비싸져 이용할 수 없을 것이다.”


이 문제는 경쟁자들이 함께 Harv를 위한 기금을 모으도록 압박하고 있다. Driscoll’s와 Naturipe 농장 같은 대규모 기업만이 아니라 지역의 농민들이 약 900만 달러를 모금했다.  

전 인텔의 엔지니어 Bob Pitzer 씨와 함께 Harv를 창안한 Wishnatzki 씨는 자기 돈 300만 달러를 투자했다. 


플로리다 G&D 농장에서 딸기 따기에 활용되는 로봇 집게발. 부드러운 촉감을 지닌 로봇을 설계하는 일이 미국의 농장을 자동화하는 데 가장 기술적인 장애물 가운데 하나이다.


전자장비 수확기는 아직 꽤 서투른 상태이다. 

지난해 시운전하면서 Harv는 사고 없이 모든 딸기 식물에서 20%의 딸기만 모았다. 올해의 목표는 딸기를 으깨거나 떨어뜨리지 않고 절반을 수확하는 것이다.  인간의 성공률은 80%에 육박하기에 Harv는 이 경쟁에서 뒤떨어진다. 

하지만 Harv는 비자나 수면 또는 병가 등이 필요없다.  기계는 수평으로 굴러가는 트럭처럼 보인다. 

아래를 들여다보면, 카메라 눈과 깜빡이는 불빛으로 안내되는 16개의 작은 강철 로봇 집게발 16개가 보인다. 

재배자들은 과실이 썩기 전에 수확할 수 있는 충분한 인력을 고용하는 일이 점점 어려워지고 있다고 한다. 미국 농업노동자의 대다수를 차지하는 멕시코 출신 농업노동자들이 더 적어지고 있다.  농민들은 소수의 미국인 농업노동자들은 더 많은 임금, 무료 주택 및 채용 보너스를 제공받아야 하루종일 농지에서 허리를 구부리길 원한다고 한다.

노동통계국의 최신 전망에 의하면, 미국 내 농업 종사자 수는 앞으로 7년 동안 유지될 것으로 예상된다.   “생산성 향상 기술들”이 기계화의 영역에서 무르익음에 따라, 작물 재배에 대한 수요가 늘더라도 농장에서는 더적은 사람을 필요로 할 것이라고 연구자들은 적었다. 

제조업도 비슷한 과정을 거쳤다. 미국의 공장들은 효율성을 향상시킨 기계 덕분에 지난 20년 동안 노동력이 차지하는 영역이 더 적어지면서 생산성이 증가했다. 

Harv 한 대는 30명의 작업을 하도록 프로그램되어 있다. 이 기계는 한번에 12줄의 딸기를 가로지르며 1초에 5개의 딸기를 따고, 하루에 9600평을 처리한다. 

그 잠재력은 트럼프 행정부가 이민 정책을 엄격히 하며 농업노동자만이 아니라 불법체류 노동자의 공급이 압박을 받는 상황에서 재배자들에게 더 매력적이라고 한다. 

최근에 작성된 노동부의 2016년 자료에 의하면, 미국의 농업노동자 85만 명 가운데 약 절반이 불법체류자이다. 

농업 분석가들은 노동력 부족으로 이미 임금이 오르고 있다고 한다. 

2014-2018년까지, 농업노동자의 평균 급여는 미국 농무부의 통계에 의하면 11.29달러에서 13.25달러로 일반 노동자들보다 빠르게 상승했다. 

애리조나 주립대학의 농경제학자들은 불법체류 노동자가 사라진다면 그들을 대체하기 위해 임금이 50% 상승할 것이며, 이는 생산비를 40% 인상시킬 것이라 한다.

그 다음, 상승하는 비용이 또 있다. 

2025년부터, 전국의 가장 큰 신선식품 생산자인 캘리포니아의 모든 농장은 하루 10시간 대신 8시간을 초과해 일하는 직원에게 임금을 지불해야 한다. 

아리조나 주립대학 W.P. Carey 비지니스 스쿨의 Morrison 농사업 부문의 학과장 Tim Richards 씨는 “국내 노동자들이 이런 일을 꺼려 하기에 자동화는 장기적 해결책이다”라고 한다. 

Wishnatzki 씨는 작년에 딸기가 손상되며 100만 달러를 잃었다고 한다. 그는 노련한 농업노동자에게 시간당 약 25달러를 지불한다.  

Harv 는 농업노동자의 필요를 줄일 테지만, 새로운 일자리도 창출할 것이라고 Wishnatzki 씨는 말한다.  그의 가족 사업인 Wish Farms는 딸기 노동자가 기술자가 되도록 훈련시킬 것이라 한다. 

“우린 그 기게를 청소하고 살균하며 고칠 사람이 필요하다”고 그는 말한다. 

일부 노동자들은 불안과 회의에 차서 그 계획을 바라본다. 

“나는 로봇을 보고,  아마 우린 더 이상 일자리를 얻지 못할 것이다’ 생각한다”고 이 농장에서 Harv와 함께 고용되어 있는 600명의 직원 가운데 하나인 48세의 Antonio Vengas 씨는 말한다. 

Vengas 씨는 멕시코 오악사카 주에서 15년 전 플로리다로 이주하여, 시간당 약 25달러를 번다. 그의 동료 가운데 약 75%는 계절노동 비자를 가진 멕시코인이다. 

그들은 모두 큰 돈을 번다고 그는 말한다. 그들은 동기부여가 된다.

“사람들은 상처를 내지 않고 딸기를 딸 수 있다.”고 그는 말한다.  “그들은 어느 것이 너무 적거나 썩었는지 안다. 기계는 그렇게 할 수 없다.”


베리-4의 타이어 자국. 먹을거리 비용을 절감하기 위해 베리-4가 인간의 능률을 초과하길 바란다. 


노동단체도 로봇이 그 일을 할 준비가 되었는지 의심스러워 한다. 

“기계는 소비자와 식품산업이 요구하는 완전한 상태를 파괴하지 않고 섬세한 생식용 포도와 딸기나 과실을 수확할 수 없다.”고 미국 전역의 농업노동자 2만 명을 대표하는 United Farm Workers of America의 정치 및 입법 이사 Giev Kashkooli 씨는 말한다. 

조합이 기술의 진보에 반대하지는 않는다고 Kashkooli 씨는 덧붙였다. 

“로봇 기술은 업무를 획기적으로 줄이고, 사람들이 더 많은 돈을 벌 수 있도록 지원하는 역할을 할 수 있다”고 그는 말했다. 

서부 이외에, 워싱턴 주립대학의 엔지니어들은 12개의 로봇팔이 있는 사과 수확 기계를 지역의 농민들과 협력하며 시험하고 있다. 

과수원의 나무들 사이의 줄을 따라 움직이며 컴퓨터 두뇌가 이미지를 스캔해서 과일을 찾는다. 로봇팔은 사과를 잡아 컨베이어벨트 위에 올린다.

앞으로 3년 이내에 이 기술이 시장에 출시될 것이라 기대한다고 이 학교의 Center for Precision & Automated Agricultural Systems의 조교수 Manoj Karkee 씨는 말한다. 

고용을 위해 애쓰는 농민들이 “어제” 그것을 원했다고 그는 말한다. 

“우린 모두 우리가 이 방향으로 가야 할 필요가 있다는 걸 알고 있다”고 Karkee 씨는 말한다.  “사과 따기의 마지막 진전은 사다리의 발명이었다.”

로봇은 농산물에 거의 상처를 내지 않는다. 하지만 오늘날, 한 대의 로봇 수확기가 적어도 30만 달러나 해서 너무 비싸다. 

Harv가 시험에 투입되는 날, 농민들과 연구원들이 Wishnatzki의 농장에 3대의 버스로 도착했다. 그들은 캐나다, 호주, 독일, 스위스 및 미국 각지에서 왔다. 매가 머리 위를 선회하듯이 하늘에 호기심이 매달려 있다. 

알버타에서 온 딸기 재배자 Blaine Staples 씨는 딸기를 쥐면서 쉬익 소리가 나는 기계 쪽으로 먼지를 뚫고 걸어갔다. 그 주위에 수십 명의 사람들이 땅에 엎드려 있었다. 구경꾼들의 두려움과 불신을 받으며 기계의 팔이 작동하기 시작했다. 

“이건 꽤나 새로운 산업혁명이다.”라고 Staples 씨가 말했다. 

그의 캐나다 농장은Wishnatzki 씨의 72만 평에 비하면 매우 작다. 하지만 그는 자신의 현재 인건비와 비슷한 수준에서 농사철에 Harv를 빌릴 수 있다. 

Harv가 제안하는 사업 모델에서, 농민은 계절 농업노동자에게 지불하는 것과 같은 비율로 기계가 따는 과일에 대해서 비용을 지불할 것이다.

노스캐롤라이나의 농민인 Doug Carrigan 씨는 딸기 두둑 위에 서 있는 Harv에서 눈을 떼지 못하고 서 있다. 

“일요일이나 공휴일도 상관없다.” Carrigan 씨는 말했다.  “기계는 그에 상관없이 일할 것이다.

그는 일꾼에게 시간당 10-14달러를 지불한다. 그들은 주로 지역의 사람들이다. 

“많은 미국인들이 게을러졌다.”고  Carrigan 씨는 말했다.  “그들은 급료를 원한다. 그들은 일자리를 원하지 않는다.”

품질을 희생시키지 않고 작업을 언제나 자동화할 수 있다면 “그것은 승리이다”라고 그는 말한다. 

농민들 뒤에서 엔지니어팀이 흰색 트레일러 안에 있는 평명  TV를 보았다. Harv 내부의 카메라가 클로즈업을 한다.


Antonio Vengas 씨.



빛이 깜박인다. 16개의 작은 로봇 팔이 회전하여 딸기를 집는다. 엔지니어들은 그걸 격렬하게 젓고 있는 오리발에 비교한다.  

“집에서 최고의 경관”이라고 24세의 기계 시각의 담당자 Alex Figueroa 씨는 말했다.

모든 게 순조롭게 운영되는 것처럼 보인다. 아무도 빵 체인점에서 주문한 오트밀 건포도 쿠키를 스트레스 때문에 먹지 않는다.  

“오류 없음!”이라고  Figueroa 씨가 큰소리로 외쳤다. 

“행운을 빈다”고 또 다른 엔지니어가 답했다.  

농지에서의 소동과 멀리 떨어져 농업노동자들은 항상 하던대로 일한다.  

밖은 26℃이지만, 그들은 햇빛을 가리려고 긴팔과 긴바지를 입고 눈 아래쪽은 스카프를 두르고 있다. 그들은 허리를 구부려 딸기를 따서 플라스틱 상자에 넣는다. 

그런 다음 딸기 두둑을 따라서 각 상자를 검사하는 감독자에게 달려간다. 그들은 성과에 따라 돈을 받는다. 속도를 늦추면 돈을 잃는 것을 뜻한다.

근처에 주차된 낡은 스쿨버스를 출퇴근할 때 무료로 이용한다. 대부분의 농업노동자들은  Wishnatzki 씨가 제공한 집에서 살고 있다. 

65세의 Santiago Velasco 씨는 35년 동안 이곳에서 일했고, 실제로 모든 일에 관여해 왔다. 수확, 삽질, 관개.  

Harv는 그가 걱정하지 않는 신참이다. 

“난 사람들이 어떻게 따는지 알고 있기에 그것이 효과가 있을 것이라 생각하지 않는다.”고 그는 말한다.  “그리고 사람들이 더 빠르다.”

그의 예측은 인간의 날을 떠받쳤다. 

로봇은 각 딸기 식물에서 절반 이상의 딸기를 발견했지만, 이번 농사철의 딸기는 예상보다 더 컸다. Harv의 집게발에서 다발이 떨어졌다. 빨갛고 과즙이 많은 건 이제 사라졌다. 

엔지니어는 얼마나 많은 비디오를 검토해야 하는지 확신하지 못한다. 그들은 Harv가 올해의 목표를 달성했다고 확신할 수 없다. 하지만 그들은 내년에 바로 그것을 얻을 수 있으리라 확신한다.

세계 최초로 사람 없이 로봇으로 재배를 시작해서 로봇으로 재배를 끝마치고, 자율주행 트랙터로 수확까지 하는 실험을 했다는 영국의 한 대학교 소식. 맥주보리를 재배했는데 이걸로 맥주까지 담근다고 한다.

일단 시작은 맥주보리였지만 앞으로 더 다양한 작물의 농사로 확대되는 날이 오겠지? 일하는 사람이 없는 농경지라... 어떤 세상이 펼쳐지려나...
