Amazon’s robots: job destroyers or dance partners? – The Seattle Times

The 100,000 orange robots that glide through Amazon warehouses and the thousands of Amazonians who build, program and use them are part of the evolving relationship between humans and their tools that awakens new possibilities but also new fears.

NORTH READING, Mass. Every day is graduation day at Amazon Robotics.

Heres where the more than 100,000 orange robots that glide along the floors of various Amazon warehouses are made, and taught their first steps.

Here they practice their first pirouettes. And heavy lifting too, as they twirl while hauling fabric shelves filled with cinder blocks.

And finally once theyve been given the green light by their makers about 38 robots assemble in a tight four-row formation and in orderly fashion wheel themselves up onto pallets that will be shipped to one of the 25 Amazon warehouses that employ automatons.

Amazon staffers call it the graduation ceremony, and it takes place several times a day.

Its a proud-mama moment, an Amazon spokeswoman said, during the first visit to the facility by a reporter since the e-commerce giant bought the former Kiva Systems in 2012. So far this year the company has graduated about 55,000 robots.

These robots, and the thousands of Amazonians who build, program and use them, are laying out the next episode in a very old story the evolving relationship between humans and their tools.

From the sharp stones wielded by our early ancestors to the internet, every step along the way has awakened new possibilities, and new fears too.

Now, its the turn of robotics, a discipline that after decades of experimentation and recent big leaps in artificial intelligence has finally reached a maturity that allows mass deployment.

Were at an inflection point the ability of robots to be useful at a low-cost point, said Beth Marcus, a robotics expert and startup founder who recently joined Amazon Robotics as a senior principal technologist.

This latest wave of automation has spurred anxiety among scholars and policymakers. They warn it might contribute to a growing economic divide, in which workers with more education or the right skills reap the benefits of automation, while those with inadequate training are replaced by robots and increasingly left out of lucrative jobs.

Its not a novel concern: Spinning jennies, which revolutionized the weaving industry, sparked similar resistance in 19th century England. And in the 1960s, the U.S. government created a task force to study the impact of technology on livelihoods. If we understand it, if we plan for it, if we apply it well, automation will not be a job destroyer or a family displaced, President Lyndon Johnson said at the time.

History has shown that, over time, job losses in rapidly advancing sectors are offset by gains in other activities spurred by a growing economy.

That perspective doesnt quell contemporary concerns. Microsoft co-founder Bill Gates has proposed taxing robotsto pay for other jobs, such as teachers. Some scholars also seem to be losing faith in the old playbook.

Theres never been a worse time to be a worker with only ordinary skills and abilities to offer, because computers, robots and other digital technologies are acquiring these skills and abilities at an extraordinary rate, Massachusetts Institute of Technology professors Erik Brynjolfsson and Andrew McAfee wrote in their 2014 book, The Second Machine Age.

In a recent report, the Organization for Economic Cooperation and Development said that technology is contributing to the disappearance of middle-skill jobs, both in manufacturing and in clerical work, even though it helps create both highly skilled and low skilled positions.

Amazon is the modern poster child for automation, and not only because of the orange warehouse robots. Its machine-learning software lets the company predict customer behavior. New retail concepts, such as the Amazon Go convenience store in downtown Seattle, heavily rely on sensor technology in an effort to do away with the need for cashiers.

Amazon is also working hard to have drones deliver items to peoples homes, a move that may replace a lot of delivery drivers.

But automation certainly hasnt slowed down Amazons colossal appetite for people. The companys payroll expansion has long exceeded revenue growth: In the quarter ended last June, its workforce grew by 42 percent to 382,400 jobs, versus sales growth of 25 percent.

Its hard to say, in the case of Amazon, how many potential human jobs have gone to the robots, or inversely, how many new positions have been created to handle this new feature of working life.

But Amazon says that warehouses equipped with robotics typically see greater job creation with more full-time employees, due to the increased volume of orders these centers can handle.

Amazon also says automation has meant the creation of desirable, high-skilled jobs designing robots and teaching them how to do things, as well as middle-skilled jobs such as repairing the robots, or simply focusing on more sophisticated warehouse tasks while letting machines do the boring stuff.

Marcus says that there are plenty of tasks humans will monopolize for a long time.

There are many things humans do really well that we dont even understand yet, Marcus said.

Amazon Robotics facility, in suburban Boston, was first established by Kiva Systems, a company founded on the concept of flipping warehouse logistics around. Instead of having workers walk to products, it sought to bring items to the workers. The solution: flat, wheeled robots called drive units that navigate a warehouse by reading stickers on the floor, all while carrying merchandise on their back.

Amazon bought Kiva in 2012 for $775 million in cash and started introducing the robots into its warehouses in 2014.

Since then, the robotics facility stopped selling to other customers, while its orange robots, now in their fourth generation, have come to play an important part in Amazons operations. In fact, robotics seem to be more important to Amazons bottom line than to other tech giants also making big bets in the field, such as Google, experts say.

For Amazon, its mission critical, said Pedro Domingos, a machine-learning expert at the University of Washington.

Tye Brady, the chief technologist for Amazon Robotics, noted that the e-commerce behemoth is in a unique spot.

We have the ability, through our automation and our robotics, to change the real world by immediately deploying the most recent advances throughout the companys widespread footprint, he said in an interview.

Brady, who joined Amazon two years ago after a two-decades-long career in aerospace and robotics, said that in his ideal vision of the future, society might look a little bit like the original Star Wars movie, in which humans and robots coexisted happily, with the latter capably helping humans lead more purposeful lives. Our machines will allow us to focus on what we want, he said.

A few steps into the Amazon Robotics building, a small sign warns visitors in jest to please not feed the robots.

Some 500 employees work in the facility, mostly engineers and scientists, as well as technicians who assemble the robots. The hardware side is led by Parris Wellman.

As a kid he wanted to build cars, and went on to earn a mechanical-engineering degree at the University of Pennsylvania. There, studying under prominent roboticist Vijay Kumar, Wellman discovered robots. After a Ph.D. from Harvard and a few years in biotech and in medical devices, he joined Amazon Robotics, returning to what he calls his first love.

What he likes about the opportunity is that he can build something and deploy it en masse pretty quickly.

Another interesting aspect of the work, he said, is that the roboticists get plenty of feedback from the warehouse associates who will be dealing directly with the robots. For example, associates helped designers pick out the color of the new lightweight fabric shelves that the robots carry: yellow, because that makes it easier to see the items they carry.

And it was a maintenance worker at a warehouse who designed, and patented with Amazons help, a metal rod that staffers use to push inactive robots around the factory floor (its easier than picking up the 750-pound robots).

Innovation is not restricted to a particular set of people, Wellman said.

In addition to hardware engineers, the facility employs software developers who animate the drive units throughout the Amazon empire. People dont realize Amazon Robotics has a huge software stack, says Jill Sestini, a developer who was Kiva Systems 30th employee when she joined in 2006.

That software prowess got a huge boost after the Amazon acquisition because of the proprietary technology the new owner brought to the table, she said.

The current job of the Boston-area native who builds motorcycles as a hobby, and comes from a family of amateur craftspeople who made their own furniture is to oversee the interfaces that allow the robots to interact with humans more easily.

One of her projects: an app on a Fire tablet that lets warehouse workers without highly advanced computer skills control the drive units when they fail or an item falls in their path. Hundreds of tablet-toting warehouse workers across the 25 highly automated warehouses operated by Amazon now have that ability.

Brady, the Amazon Robotics chief technologist, says the roboticists efforts have brought a more than 50 percent increase in storage efficiency at the Amazon warehouses that employ robots. That means they can contain more items in a smaller space.

These warehouses are also where Amazon figures out how people and machines can work together as in a beautiful symphony, according to Brady.

One of these centers is in DuPont, Pierce County, a warehouse dedicated to mid-size and large items, where 500 humans work alongside hundreds of robots. There the automatons have the run of the core of the warehouse, a maze brimming with metal shelves stocked with merchandise.

They operate in a different space from the humans, who are mostly on the outskirts of the facility. But they work together in an elaborate, seemingly seamless dance.

The robots bring empty shelves out from the depths of the warehouse to a person who loads them with individual items unpacked from pallets as they arrive at the distribution center. The robot then races back into the interior of the facility, putting the shelf back in its place. The automatons can lift up to 3,000 pounds.

When an order comes in, a human operator in another part of the warehouse calls up an item from a computer. A robot will then wheel out the shelf containing the item, which the human will pick out and place on a conveyor belt.

The interaction with the robotic workforce has created new types of roles.

Barry Tormoehlen, a former electrician and conveyance mechanic, is one of a dozen people at DuPont who do preventive maintenance on the drive units, wipe them down every once in a while and fix them when needed.

Over time, Tormoehlen has learned to recognize the individual units, which each have a number and a maintenance history of their own. The collaboration between these robots and humans has created a local folklore.

Workers have painted some of the robots to give them personality: A robot with fiery flames on its sides is known as the devil drive. Another, decorated by warehouse workers in blue and yellow instead of the usual orange, is dubbed The Minion, after animated characters who have the same color pattern.

During a recent visit to the DuPont center, 29-year old Ashley Parks, a former medical assistant from Yelm, Thurston County, stowed newly arrived items of various shapes and sizes onto a shelf atop The Minion.

They kind of dance around you, she said of the automatons, adding that they make her more efficient in her job.

As for fears of one day losing her job to a machine, she seemed nonchalant. I dont think theyre going to take away our jobs, she said. They stay on their side, I stay on my side.
