Standards, Technology Lead Way To Collaborative Robots

Standards, Technology Lead Way To Collaborative Robots

The most exciting thing happening now with industrial robots is the new intimacy of human and machine–collaborative robots.

Since I had other plans and could not attend the Rockwell Automation track at the EHS Conference coming up in Pittsburgh, Rockwell brought a piece of the safety symposium to me. George Schuster, a member of the global safety team at Rockwell and a robotics safety expert, discussed the current state of the art with me.

Schuster told me that Rockwell Automation is working with Fanuc Robots to change the way people and machinery interact.

There is much interest in the work in the user community to create manufacturing processes that leverage the strengths of machines (stability, reliability, strength) and the intelligence and adaptability of humans.

“In the past we engineered to keep them separate or at least arbitrate the shared space. Now we’ve found good benefits to engineer ways for people and machines to work together,” said Schuster.

Three things are enabling this approach. First, there are the standards. ISO 10218 and ANSI/RIA 15.06-2012 give guidance for designers. They also make it clear that thorough risk assessments must be carried out when designing these processes. Next, Rockwell is blending its safety technology with robotics. Then design approaches are looking holistically at what is possible with human and machine working together. Together, this is actually more of an application space rather than just technology.

Increasingly working on removing barriers between robotics and controllers, technology includes connectivity and safety–EtherNet/IP Safe; GuardLogix system; Add-on profiles in software-pre-engineered common data structure; part of the Connected Enterprise, includes connection of devices plus communication to upper levels to collect and analyze information–all working together.

There are four key current applications: ability to stop robot without killing power to allow operator to interact for instance load/unload, can quickly enter/leave area; hand guided operation, person can move/guide robot kind of like ergonomic load assist; speed and separation monitor, sensor system detects presence and position of personnel, modulates robot, can stop if person gets too close, coordinates robot speed and approaching person; power force limiting-this one is a little tricky, it’s hard to know where the robot will come in contact and what force is acceptable to the human, difference between soft flesh and hard place, etc.

This is all cool. It is ushering in a new era of manufacturing.

Industrial Robotics Market Grew in 2015

Few conversations or panels at the recently completed ARC Industry Forum touched directly on discrete automation. That is, with one notable exception. Robotics. Several people brought up a surge in orders for industrial robotics.

Aside from human-robot collaboration, not much has been exciting in the industrial space. I keep hoping for some advances using some of the innovation being explored in the consumer space.

But I looked up the latest from the Robotic Industries Association (RIA) and learned that robot orders and shipments in North America set new records in 2015. A study of the numbers, though, reveals that the drivers were the same old drivers–automotive industry with coating/dispensing, material handling, and spot welding leading the charge.

Industrial Robotic Sales

A total of 31,464 robots valued at $1.8 billion were ordered from North American companies during 2015, an increase of 14% in units and 11% in dollars over 2014. Robot shipments also set new records, with 28,049 robots valued at $1.6 billion shipped to North American customers in 2015. Shipments grew 10% in units and nine percent in dollars over the previous records set in 2014.

The automotive industry was the primary driver of growth in 2015, with robot orders increasing 19% year over year. Non-automotive robot orders grew five percent over 2014. The leading non-automotive industry in 2015 in terms of order growth was Semiconductors and Electronics at 35%.

According to Alex Shikany, Director of Market Analysis for RIA, the fastest growing applications for robot orders in North America in 2015 were Coating and Dispensing (+49%), Material Handling (+24%), and Spot Welding (+22%). RIA estimates that some 260,000 robots are now at use in North American factories, which is third to Japan and China in robot use.

The recent record performance by the robotics market in North America is concurrent with falling unemployment. Last month, the Bureau of Labor Statistics announced that the unemployment rate in the United States reached 4.9%, its lowest level since February of 2008.

“Today there are more opportunities than ever before in the robotics industry,” said Jeff Burnstein, President of RIA. “The continuing growth in robotics is opening many new job opportunities for people who can program, install, run, and maintain robots. In fact, if you look closer at the jobs discussion, automation is helping to save and create jobs. A lot of companies tell us they wouldn’t be in business without robotics and related automation.”

Burnstein noted that the RIA and its sister group AIA – Advancing Vision + Imaging, are seeing the impacts of the growth in demand for automation in upcoming events like the International Collaborative Robots Workshop and The Vision Show, slated for May 3-5, 2016 in Boston.

“Collaborative robots are the hottest topic in robotics today, and we are expecting a strong turnout in Boston for the workshop,” he said. “With interest in vision and imaging at an all-time high, AIA expects its flagship trade show, The Vision Show, to draw record attendance this year,” Burnstein added.

PwC Industrial Manufacturing Trends 2016

The PwC Industrial Manufacturing Trends 2016 post has been released. Check it out. There are some interesting ideas.

The authors Stephen Pillsbury and Robert Bono cite the painful lessons of recovering from 2001 and 2008 as leading to caution now displayed by manufacturing leaders. We’ve had a bit of an economic jolt. Where is it headed? The uncertainty leads to caution.

They reach an interesting conclusion, “Manufacturing may be facing some headwinds, but it’s undeniably in the midst of a technological renaissance that is transforming the look, systems, and processes of the modern factory. Despite the risks — and despite recent history — industrial manufacturing companies cannot afford to ignore these advances. By embracing them now, they can improve productivity in their own plants, compete against rivals, and maintain an edge with customers who are seeking their own gains from innovation.”

It is time, they say, to envision and prepare for a data-driven factory of the future.

They reveal four technology categories that are already driving much of the change. I’ll summarize. Check out the report for more depth. Most of these are not surprising, but they certainly must be factored in the thinking of manufacturing leaders.

Industrial Manufacturing Technologies

  • Internet of Things (IoT): The connected factory is an idea that has been evolving for the past few years. Increasingly, it means expanding the power of the Web to link machines, sensors, computers, and humans in order to enable new levels of information monitoring, collection, processing, and analysis.

    But for industrial manufacturing companies, the next generation of IoT technology should go well beyond real-time monitoring to connected information platforms that leverage data and advanced analytics to deliver higher-quality, more durable, and more reliable products.

    Before investing in IoT, however, industrial manufacturing companies must determine precisely what data is most valuable to collect, as well as gauge the efficacy of the analytical structures that will be used to assess the data. In addition, next-generation equipment will require a next-generation mix of workers, which should include employees who can design and build IoT products as well as data scientists who can analyze output.

  • Robotics: In many cases, robots are employed to complement rather than replace workers. This concept, known as “cobotics,” teams operators and machines in order to make complex parts of the assembly process faster, easier, and safer.Cobotics is rapidly gaining momentum, and successful implementations to date have focused largely on specific ergonomically challenging tasks within the aerospace and automotive industries. But these applications will expand as automation developers introduce more sophisticated sensors and more adaptable, highly functional robotic equipment that will let humans and machines interact deftly on the factory floor.
  • Augmented reality: Recent advances in computer vision, computer science, information technology, and engineering have enabled manufacturers to deliver real-time information and guidance at the point of use.
  • 3D printing: Also known as additive manufacturing, 3D printing technology produces solid objects from digital designs by building up multiple layers of plastic, resin, or other materials in a precisely determined shape.

The authors conclude with recommendations of how to consider necessary investments in these emerging technologies.

Robots and Humans Collaborating for Manufacturing Success

Robots and Humans Collaborating for Manufacturing Success

Rethink Robotics SawyerMy grandson was asking about why can’t we build a better light bulb and design better batteries. He’s eight. If he keeps asking the big questions, he’ll have a good future.

I told him that there would always be problems to solve, that’s why we would need engineers and scientists. He asked, what kind of questions. I told him about the need to develop robots that could work with people. This technology will become increasingly useful to help an aging population cope with physical limitations. It will also help production when we (shortly) face a declining workforce.

I like to point to the work of Rethink Robotics. It recently announced that its Sawyer robot, the company’s second smart, collaborative robot designed for a wide range of factory environments, is available for purchase and is being deployed by manufacturers across the globe. Announced in March, Sawyer is a single-arm, high-performance robot created to handle machine tending, circuit board testing and other precise tasks that have been difficult to automate with existing robots.

Weighing only 19 kilograms (42 pounds), Sawyer features a 4kg (8.8 lbs.) payload, with seven degrees of freedom and a 1260mm reach that can maneuver into the tight spaces and varied alignments of work cells designed for humans. Its high resolution force sensing, embedded at each joint, enables Rethink Robotics’ compliant motion control, which allows the robot to “feel” its way into fixtures or machines, even when parts or positions vary. This characteristic enables a repeatability that is unique to the robotics industry, and allows Sawyer to work effectively in semi-structured environments on tasks requiring 0.1mm of tolerance.

Sawyer offers a unique combination of features that distinguish it from other conventional and collaborative robots, including compliant motion control, embedded vision with a built-in Cognex camera and Rethink’s Robot Positioning System, a component of the proprietary and industry-leading Intera software platform. Powering both Sawyer and Rethink’s first collaborative robot, Baxter, the Intera system makes deploying the robots far easier than typical industrial robots. While traditional robots typically take an average of 200 hours to program and deploy, Sawyer can be deployed in under two hours and can easily be trained by typical factory technicians – not roboticists.

Sawyer is purpose-designed for enterprise-level deployments, with a useful life of 35,000 hours of operation. The robot is IP54-rated, making it ideal for harsh factory environments. Since its introduction, Sawyer has been field tested extensively at leading manufacturers’ sites around the world, and is currently being deployed on production lines in many of those facilities.

The process improves the efficiency of the product line while allowing GE’s employees to handle the more dexterous and cognitive work needed to complete the task.

General Electric has been testing Sawyer over the past month and will deploy their first robot in a GE Lighting plant in Hendersonville, North Carolina. A prime example of true human-robot collaboration, Sawyer will be on a production line positioning parts into a light fixture as a GE employee completes the assembly. The process improves the efficiency of the product line while allowing GE’s employees to handle the more dexterous and cognitive work needed to complete the task.

“The ability to deploy a smart, collaborative robot like Sawyer provides a significant flexibility advantage to our production team, while still meeting our world class quality, precision and speed standards,” said Kelley Brooks, global advanced manufacturing & engineering leader at GE Lighting. “Utilizing this technology is an integral part of our Brilliant Factory initiative to connect all parts of the supply chain from product design, to engineering, to the factory floor and beyond in order to deliver customized LED solutions for our customers.”

Sawyer is also set to be deployed in Steelcase Inc.’s (NYSE: SCS) Grand Rapids factory, where it will work in tandem with the company’s welding machine. Sawyer will work to pick and place parts in pairs of two, enabling a completely autonomous welding process. The robot’s small footprint, long reach and higher payload capacity make it ideal for the Steelcase team. In addition to handling changes in parts and lines seamlessly, Sawyer’s IP54 rating allows the robot to work in manufacturing environments with liquids and particle hazards present.

“Having already deployed several Baxter robots successfully, we’ve seen the value that collaborative robots bring to the factory floor,” said Edward Vander Bilt, leader of innovation at Steelcase. “These robots are the game-changers of modern manufacturing, and Rethink Robotics is leading the evolving relationship between humans and machines that allow each to do what they do best.”

Sawyer is a significant addition to the company’s smart, collaborative robot family, which also includes the groundbreaking Baxter robot that defined the category of safe, interactive, affordable automation. Sawyer is available for purchase in manufacturing environments throughout North America, Europe and Asia-Pacific.

“After announcing Sawyer in March, the worldwide demand we have seen for the robot has been overwhelming,” said Rethink Robotics President and Chief Executive Officer Scott Eckert. “Manufacturers around the globe understand that Sawyer opens the door for a wealth of new applications and opportunities to improve their business, and they are eager to get it onto their production floors.”

More Robots Do Not Equal Manufacturing Job Losses

The Association for Advancing Automation (A3) today published a white paper entitled “Robots Fuel the Next Wave of U.S. Productivity and Job Growth” in which data from the Bureau of Labor Statistics and a wide range of manufacturing firms document how and why increasing the use of robots is associated with increased employment.

A3 White Paper Robots and Employment

Key statistics from the A3 white paper show that during the non-recessionary periods – 1996-2000, 2002-2007, and 2010-2014 – general employment and robot shipments both increased. Since 2010, the robotics industry in the United States has grown substantially. Even during this period of record-breaking robot sales, U.S. employment increased. This new data is in stark contrast to media coverage and a perception that increasing use of robots causes higher rates of unemployment in the U.S.

At a glance:

  • Robots save and create jobs
  • Robots take care of the dull, dirty, or dangerous jobs
  • Robots extend workplace functionality, improving the bottom line
  • Robots are reviving American manufacturing
  • Robots create better, safer, higher paying jobs

“We are seeing concrete shifts in the factors that resulted in cuts to the U.S. manufacturing work force over the past few decades,” said Jeff Burnstein, president of A3. “Manufacturing automation increasingly provides the flexibility in the variety of tasks robots perform to drive improvements in overall product quality and time to market.”

Burnstein concluded, “One of the biggest challenges we now face is closing the skills gap to fill jobs. Robots are optimizing production more than ever, increasing global competitiveness, and performing dull, dirty and dangerous tasks that enable companies to create higher-skilled, better-paying, and safer jobs where people use their brains, not their brawn.”

Correlation does not equal causation

The white paper overlays graphs of robot sales and US employment. I asked Burnstein if he is trying to show causation from the correlation. He said that was not the intent. “It is not so much to show causation as it is simply to refute the argument,” he told me in an interview preceding the release. Taking the argument that robots cause unemployment, one would expect climbing robot sales to be reflected in declining employment. Statistics do not support that supposition.

Anecdotal evidence

As companies seek to bring manufacturing operations stateside while remaining cost-competitive, they continue to turn to automation to help lead the new wave of productivity and job growth in the U.S.

“The whole premise for our company is to bring manufacturing back to this country, and our new robot fits perfectly with that master plan,” said Geoff Escalette, CEO of faucet-maker RSS Manufacturing & Phylrich in Costa Mesa, California. “Our robot not only makes it possible to increase production speed without buying additional CNC machines, but also helped us open up 30 percent more capacity on existing machinery.”

Robotics also helps companies stay competitive when seeking new talent—particularly those who are interested in long-lasting careers working with technology.

“It’s really an opportunity for us to grow,” reports Matt Tyler, president and CEO of Vickers Engineering, a contract precision engineering manufacturer in Michigan. “Because we have robotics and are able to compete on a global scale, it makes the U.S. more competitive in manufacturing, and that’s good for all of us.”

The white paper includes notes from other manufacturers who both acquired additional automation and people.

The Association for Advancing Automation is the global advocate for the benefits of automating. A3 promotes automation technologies and ideas that transform the way business is done. A3 is the umbrella group for Robotic Industries Association (RIA), AIA – Advancing Vision + Imaging, and Motion Control & Motor Association (MCMA). RIA, AIA, and MCA combined represent some 850 automation manufacturers, component suppliers, system integrators, end users, research groups and consulting firms from throughout the world that drive automation forward.
