Robots have been used in manufacturing for some time now. General
Motors used its first robot in 1961, at a plant in Ewing, New Jersey, a
location I routinely drive past on the way to my local library. (It’s now a level
brownfield.) That robot weighed 4,000 pounds and was used to weld and move
parts weighing as much as 500 pounds. The brute strength and speed that such robots
brought to the workplace made them dangerous to work alongside. For the sake of
safety, they were segregated in enclosures and other closed workspaces. They
also have been used in conditions that are hostile to humans, such as the
chambers where paint is sprayed on automobile bodies.
This practice is starting to change as a
new generation of slower and more lightweight robots is being rolled out. For
example, at the Spartanburg BMW plant, a Danish-made robot rolls a layer of
protective foil over the electronics in car doors, a task that would cause
repetitive-strain injury if done by humans. This is something that more
old-fashioned robots could do, but that would mean isolating the car for a task
that is better done alongside tasks that humans are doing. Over the next couple
of years, the BMW plant’s engineers intend to configure robots to hand tools
and parts to human workers.
One manufacturer has added fake eyes to the “head” of its
robot so the robot can signal by a simulated facial expression where it is
going to move next. Robots are also being designed to react to contact with
humans. Most simply, this means the robot pulls back when it meets resistance.
More sophisticated robots are designed so a human can move the robotic arm
through a sequence of operations and the robot will then be able to repeat the
sequence. This makes it unnecessary to pay a highly skilled programmer each
time the robot needs to be configured perform a new task, and that means that
robots can be used for small-batch manufacturing, where the tasks are
constantly changing.
As robots gain improved capabilities, their presence in the
workforce keeps growing. The International Federation of Robotics reports
that 26,269 industrial robots were sold in North America in 2012, and the
Federation projects that sales will exceed 31,000 by 2016.
So what skills will be necessary for human-robot teamwork?
As robots become more reliable, mechanical skill will diminish in importance. And
as robots gain sophisticated ways to receive instructions, the traditional
collaborative skill of communication will become more important. Human workers
will need to remember to keep their robotic teammates in the loop whenever the
work routine changes, even slightly. With voice-activated robots, humans will need
to learn the particular commands that the robot can respond to.
But the most important skill humans can bring to the
collaboration is the uniquely human ability to be creative. The most successful
human co-workers will be those who are constantly finding original ways to
improve productivity and the quality of output. Of course, this is nothing new.
It was true even before the industrial age. However, as robots become
increasingly capable of mastering skills such as attention to detail, learning,
and flexibility, the jobs where workers can collaborate with them—rather than be
replaced by them—will be the jobs that require a high level of skill at
creative problem solving.
