Workers adapt to robots in warehouse

NORTH HAVEN, Conn. (AP)- Robot-makers say their machines are taking on the most mundane and physically strenuous tasks. In reality, they are also creating new forms of stress and strain.

Amazon is leading the robotic push with more than 200,000 robotic vehicles it calls “drives” that are moving goods through its U.S. warehouses. Amazon’s big investment has also sparked its rivals to add on robots to speed up delivery times and bring down costs.

“They weigh a lot,” Amazon worker Amanda Taillon said during the pre-Christmas rush at a company warehouse in Connecticut.

Taillon’s job is to enter a cage and tame Amazon’s wheeled warehouse robots for long enough to pick up a fallen toy or relieve a traffic jam. She straps on a light-up utility belt, that commands the nearest robots to abruptly halt and the others to slow down.

Taillon says she’s gotten used to working with robots — something Amazon and its rivals are increasingly requiring warehouse employees to do. Amazon has moving robots that are moving goods through its delivery-fulfillment centers around the U.S.

Its rivals have taken notice, and many are adding their own robots in a race to speed up productivity and bring down costs.

Without these fast-moving pods, robotic arms and other forms of warehouse automation, retailers say they wouldn’t be able to fulfill consumer demand for packages that can land on doorsteps the day after you order them online.

There are growing concerns that keeping up with the pace of the latest artificial intelligence technology is taking a toll on human workers’ health, safety and morale.

Warehouses powered by robotics and AI software are leading to human burnout by adding more work and upping the pressure on workers to speed up their performance, said Beth Gutelius, who studies urban economic development at the University of Illinois at Chicago.

It’s not that workers aren’t getting trained on how to work with robots safely. “The problem is it becomes very difficult to do so when the productivity standards are set so high,” she said.

Much of the boom in warehouse robotics has its roots in Amazon’s $775 million purchase of Massachusetts startup Kiva Systems in 2012. The tech giant re-branded it as Amazon Robotics and transformed it into an in-house laboratory that for seven years has been designing and building Amazon’s robot armada.

Amazon’s Kiva purchase “set the tone for all the other retailers to stand up and pay attention,” said Jim Liefer, CEO of San Francisco startup Kindred AI, which makes an artificially intelligent robotic arm that grasps and sorts items for retailers such as The Gap.

Amazon this year bought another warehouse robotics startup, Colorado-based Canvas Technology, which builds wheeled robots guided by computer vision. Such robots would be more fully autonomous than Amazon’s current fleet of caged-off vehicles, which have to follow bar codes and previously mapped routes within warehouses.

The tech giant is also still rolling out new models descended from the Kiva line, including the Pegasus, a squarish vehicle with a conveyor belt on top that can be found working the early-morning shift at a warehouse in the Phoenix suburb of Goodyear, Arizona. A crisscrossing fleet of robots carries packaged items across the floor and drops them into chutes based on the zip code of their final destination.

All of this is transforming warehouse work in a way that the head of Amazon Robotics says can “extend human capability” by shifting people to what they are best at: problem-solving, common sense and thinking on their feet.

“The efficiencies we gain from our associates and robotics working together harmoniously — what I like to call a symphony of humans and machines working together — allows us to pass along a lower cost to our customer,” said Tye Brady, Amazon Robotics’ chief technologist.

Brady said worker safety remains the top priority and ergonomic design is engineered into the systems at the beginning of the design stage. Gutelius, the University of Illinois researcher, said that the aspiration for symphonic human-machine operations is not always working out in practice.

A recent journalistic investigation of injury rates at Amazon warehouses from The Center for Investigative Reporting’s Reveal found that robotic warehouses reported more injuries than those without.

Reveal looked at records from 28 Amazon warehouses in 16 states and found that the overall rate of serious injuries was more than double the warehousing industry average. Amazon has countered it’s misleading to compare its rate with rivals because of the company’s “aggressive stance on recording injuries no matter how big or small.”

The Reveal report also found a correlation between robots and safety problems, such as in Tracy, California, where the serious injury rate nearly quadrupled in the four years after robots were introduced.

Melonee Wise, CEO of California-based Fetch Robotics, which sells its autonomous robotic carts to retailers and other clients, credits Amazon’s Kiva acquisition for propelling innovation in the industry.

But she said that Amazon’s system forces workers to do “un-ergonomic moves” such as reaching up high or crouching down to pick out and stow inventory into the shelves-on-wheels.

“They have robots that live in cages,” she said. “Our robots are designed to work safely around people, which is a very large distinction between the two systems.”

Amazon hasn’t disclosed how its safety record at robot-powered warehouses compares to those without. But company officials remain optimistic that Amazon workers are adapting to the new technology.
