OM in the News: The Rise of Industrial Robots

baxter robotRobots will replace a growing number of jobs in industries including automotive and electronics in the next few years, particularly in east Asia, according to The Financial Times (Feb.10, 2015). Worldwide sales of industrial robots rose 23% last year and are on course to double (to 400,000) by 2018, driving radical change in many manufacturing sectors. Although robots have been used in industry for decades, recent advances in technology have cut their costs and increased their capabilities, as a new generation of reprogrammable, multipurpose machines comes into service.

The prices of industrial robots have been falling steadily, dropping about 14% in the past 4 years to $133,000 for a typical system, while capabilities have been expanding. Some robots are even cheaper: the Baxter robot from Rethink Robotics has a listed base price of $25,000, making it accessible to smaller companies that might have found it difficult to invest in earlier generations.

Advanced robots are set to cut costs and raise productivity, reducing employment in manufacturing in developed countries, while raising the skill levels demanded of the staff that remain. They are also likely to make labor costs a less significant factor for manufacturers making decisions about where to invest. In the manufacturing sectors that are the most readily automated, including cars and other transport equipment, computers and electronics and electrical equipment, about 85% of tasks can be performed by robots. Historically robots have been very rigid, and unable to apply logic to what’s in front of them, but the new generation will be applying logic to the environment and making their own decisions

The fastest adoption will come in South Korea, Taiwan and Thailand, which have heavy concentrations of the industries that are capable of high levels of automation, higher labor costs than some of their regional competitors, and limited employment protections that would prevent job cuts. Other relatively rapid adopters are expected to be China, Japan, the US, the UK and Canada. The countries likely to be slowest to embrace the new robots include more heavily regulated economies of Europe including France, Italy and Spain, as well as Brazil and India.

Classroom discussion questions:

1. Robots have been around for decades. Why the growth spurt in their use?

2. Why is SE Asia the fastest growth area?

OM in the News: Uncaged, Robots Become Gentler

FACTORY robots are usually caged off from humans on the assembly line lest the machines’ powerful steel arms deliver an accidental, bone-crunching right hook. But now, reports The New York Times (March 31, 2013), gentler industrial robots are coming out from behind their protective fences to work shoulder-to-shoulder with people. It’s an advance made possible by sophisticated algorithms and improvements in sensing technologies like computer vision.

The key to these new robots is the ability to respond more flexibly, anticipating and adjusting to what humans want. That is in contrast to earlier generations of robots that often required extensive programming to change the smallest details of their routine. A Georgia Tech prof states: “Robots of the future won’t just be in manufacturing. Almost any area could have a robot that would help make our life easier, whether lifting patients in hospital beds or helping at home.”

Gentle, helpful robots aren’t just being created in labs; they are also arriving in the marketplace. Since January, Rethink Robotics of Boston has been sending customers its two-armed robot called Baxter, which can work uncaged, moving among people. Baxter’s cameras inspect what is to be lifted, recognizing an object from many angles. In the coming year, Baxter will be able to grab objects not only from above, but also from the side, putting them into a milling machine, for example, and pressing the “go” button. It will also be able to connect with other machines to synchronize tasks.

“Baxter is a great starting point for this new generation of robots,” adds the Georgia Tech prof, “making the technology accessible to companies that before would have had to pay hundreds of thousands of dollars.”

Discussion questions:

1. How have robots evolved in the past 20 years?

2. What are some operations functions that a robot like Baxter can help improve?
