New RIA Article: The Intricacies of Industrial Robot Design

February 11, 2013

In a new RIA article, Bennett Brumson looks at how application influences the interplay of design and software architecture for industrial robots. He talks with industry pros about how the needs of the user influence design — and how that will affect the future of industrial robots.

Robot Design, Integrated Controls and Software Architectures of Industrial Robots
by Bennett Brumson

The software architecture of industrial robots, the “brains” of an automated work cell, enables the robot to perform assigned tasks quickly, repeatedly and accurately.

“Robotics are all about the requirements of an application, such as reach, speed, payload, inertia, joint rotation and performance. Robots look different because they can be used for many different applications,” says Claude Dinsmoor, Material Handling General Manager at FANUC Robotics America Corp. (Rochester Hills, Michigan). “Software and controls generally have a baseline architecture but have a built-in unique architecture on top of that aimed at an application.”

As computing power increases and software becomes more sophisticated, robot design architectures evolve to keep pace while maintaining robotics’ inherent flexibility.

Industry Pros See Positive Outlook for Robotics in 2013

January 8, 2013

December always wraps up with a look at the past year and January always starts with a look towards the future. What will 2013 bring for the robotics industry? Bennett Brumon checks in with several top industry professionals to see what trends and market shifts they’re predicting.

Robotics Industry Expected to Thrive in 2013
by Bennett Brumon , Contributing Editor

Most players in the robotics industry are sanguine on the prospects of nearly all applications in 2013. “I think 2013 will be awesome. General industry is historically two years behind the rebound of the automotive industry, following an economic downturn. The automotive industry did not buy anything for a few years then came on strong,” says Edward Minch, Automotive Group Director of Sales and Engineering at Kawasaki Robotics (USA) Inc. (Wixom, Michigan). “General industry is taking care of capital investment it ignored during the recession.”

Likewise, Mick Estes, General Manager at FANUC Robotics America Corp. (Rochester Hills, Michigan) says, “I expect to see continued growth in the automotive industry with increasing investment of robotics in the power train sector. Tier Two suppliers continue to invest in robotics to remain competitive on the world market.”

Estes also anticipates strong growth in general industry. “Packaging and palletizing applications as well as assembly for the general industrial market will increase.”

John Bubnikovich, Executive Director of Marketing and Business Development at ABB Inc. (Auburn Hills, Michigan) speaks of the continuing role of the automotive sector within the robotics industry. “The automotive sector still accounts for 65 percent of the North American robotics market. Automotive’s revitalization has been very influential in the great bounce-back the robotics industry has seen recently.”

Bubnikovich goes on to say, “Robotic laser cutting is emerging as an optimal means to cut and trim hot-stamped steel, a light weight, high strength material increasingly used in the automotive industry to reduce the overall cost and weight of cars while improving passenger safety and fuel economy.”

Bin picking is one application several leaders in the robotics industry have high hopes for in 2013. “I see rapid expansion of three-dimensional bin picking, the ability to retrieve randomly arranged products from a bin,” says John Burg, President of Ellison Technologies Automation (Council Bluffs, Iowa).

Terry Zarnowski, Director of Sales and Marketing with Schneider Packaging Equipment Co. Inc. (Brewerton, New York) has a similar outlook for the prospects of bin picking in 2013. “Bin picking is now a viable reality.”

Minch sees advancements in vision technology combined with improved force sensing, as one of numerous bright spots for the robotics industry. “These advancements will help the robotics industry penetrate into new markets, such as consumer electronic equipment and automotive component assembly and random bin picking. Robots can ‘see’ and have a sense of touch. Force sensors use feedback from servomotors to tell how hard the robot is pushing on a part during assembly processes such as driving a screw.”

(Ann Arbor, Michigan) Conference registration is now open for Automate 2013, North America’s leading automation event that takes place January 21-24 at McCormick Place in Chicago.

“The 2013 Conference is the strongest we’ve ever put together,” says Jeff Burnstein, President of the Association for Advancing Automation, the main organizer of Automate 2013.

“We’re gearing many sessions to small and medium sized companies who are new users or considering using robotics, vision, motion control, and other automation technologies,” Burnstein asserts. One of the featured sessions highlights small company executives who have successfully automated in order to become stronger global competitors. Speakers include Drew Greenblatt, President, Marlin Steel, Torben Christensen, President, Wiscon Products and Matt Tyler, President & CEO, Vickers Engineering.

“I think companies considering automating will find this session fascinating because it will provide real-world examples of companies who would have had to either go out of business or send manufacturing offshore but instead succeeded by automating,” Burnstein said.

Other key topics covered in the conference include the fundamentals of robotics and the fundamentals of vision, new developments in industrial robot safety, new motor and drive technologies, robotics system integration, motion control technology for increasing throughput, and practical applications using vision guided robots.

More than 75 industry experts from around the world will give presentations at the five-day conference (ending January 25). Keynote speakers include Steve Forbes, Chairman and Editor-in-Chief of Forbes Media and Henrik Christensen, Director of Robotics at Georgia Institute of Technology.

Professionals in the vision industry can take special classes that are required to earn the highly-coveted Certified Vision Professional (CVP) designation. The CVP is offered at both the Basic and Advanced Levels, with testing also offered at Automate 2013.

The Automate conference is accompanied by a four-day trade show featuring exhibits from some 150 leading automation companies. It offers a broad-range of automation solutions for packaging, welding, assembly, material removal, inspection, painting & coating, and other leading applications.

Burnstein said the front of the show is dedicated to exhibits from system integrators, the ideal starting point for users just beginning to investigate automation or those looking for new ideas. “The integrators are the ones who put successful solutions together, so they are extremely important to the user community,” he noted.

Another show-floor highlight will be Expert Huddles, small group discussions on key topics of interest to users. “These huddles will feature industry experts leading the discussion – among the topics will be return on investment, the best first tasks for automation, and how to select a system integrator. We expect to have more than 75 huddles throughout the show and all of them are free to show and conference attendees.”

Trade show attendance is free (16 and over required). Fees are required for the Automate 2013 conference. Full details can be found at www.automate2013.com. Automate 2013 is collocated with ProMat (sponsored by the Material Handling Industry of America). ProMat is North America’s premier material handling and logistics show. “Having both of these shows together gives attendees a chance to explore the state of the art in automation solutions as well as seeing what’s coming next for both the automation and material handling industries,” Burnstein noted.

Palletizing and De-Palletizing Applications

May 23, 2012

Robotic Industries Association

Robotics have been a staple of manufacturing for decades. Improvements to end-of-arm tooling, software, and vision systems have pushed flexible robotics downstream of manufacturing to perform palletizing and de-palletizing tasks. Subsequent to manufacturing, robots also apply packaging and ready these packaged goods for transport by stacking assemblies onto pallets for distribution.

“I see exciting developments in logistics and distribution applications. Recent enhancements of software and gripping technology help assemble unique, custom built-to-order pallet loads of different size items,” says Richard Motley, Senior Account Manager at FANUC Robotics America Corp. (Rochester Hills, Michigan).

The proliferation of new packaging and the ergonomics of palletizing and de-palletizing jobs provides manufacturers and distributors increased incentives to deploy robotics. Palletizing and de-palletizing applications show promise for continued growth within the robotics industry.

From Hard to Flexible Automation
Conventional palletizing systems have dominated the market for decades but integrators see a trend moving towards robotics, says Terry Zarnowski, Schneider Packaging Equipment Co. Inc.‘s (Brewerton, New York) Sales and Marketing Director. “The biggest trend we see is a movement towards robotics from conventional palletizers. Robotic palletizers provide flexibility and the ability to palletize different stock-keeping units (SKU) with minimal or no change over. Existing conventional palletizers are aging and we have been getting more requests from our customers to replace conventional systems with robotics.” Conventional palletizers cannot handle multiple SKUs effectively.

Until relatively recently, Zarnowski says, a manufacturing line ran a dedicated product over the course of several years. “Now, we see much shorter runs of products that might be on the market for only a year or two. The manufacturer will change something about the product or it’s packaging to make that product more marketable to consumers.” Those changes require flexibility, a feature most old-style conventional palletizers lack, says Zarnowski. “Palletizing and de-palletizing applications have really taken off and is the largest growth sector of our business. We have shipped hundreds of robots for these applications in recent years.”

As conventional palletizers make way for robot-based palletizing and de-palletizing, the process is less centralized using smaller robots. “We see the decentralization of palletizing and much more end-of-line palletizing. We see the movement towards this configuration and a movement away from the traditional configuration that used bigger robots in large-scale palletizing work cells,” notes Rick Tallian, Consumer Industry Manager at ABB Inc. (Auburn Hills, Michigan). “This configuration allows end-users more versatility in system design and reduces material handling expenditures on equipment such as conveyors.”

New Packages for New Products
The inherent flexibility of robotics lends itself to the rapid growth in handling new packaging designs, says Earl Wohlrab, Palletizing and Robotics Systems Product Manager with Intelligrated Systems Inc. (St. Louis, Missouri). “Packaging types have changed quite a bit over the last several years. These new packages are increasingly difficult to handle. Packaging is moving away from rigid corrugate casing.”

Wohlrab says more environmentally friendly packaging with more desirable graphics for consumers continues to impact the palletizing and de-palletizing market. “Those changes lead people towards robotics.” The speed of robotics is always increasing and will soon rival conventional case palletizers when manipulating less rigid packaging, Wohlrab concludes.

Likewise, Thomas Herndon, General Manager at FIPA Inc. (Cary, North Carolina) speaks of future products wrapped in new packaging types that robots will be called on to handle. “New packing designs and new products have to be handled somehow. The people who design new packaging intended to catch a consumer’s eye are not the ones who design the machine that will pick it up. Packaging materials are changing, becoming more porous due to the use of recycled products. Consumers want green packaging.”

Herndon turns his attention to new pallet designs. “The pallets themselves have changed, with less wooden and more plastic pallets. New style pallets for frozen foods allow air circulation throughout to ensure the product on the pallet is frozen evenly.” Like new packaging designs, Herndon says developers of new pallets did not consider how plastic pallets will be handled. “Some plastic pallets are just a grate, which are difficult to grab by the edges if wedged next to each other.” These grate-like pallets cannot be grasped by vacuum grippers but require more complex expansion grippers for manipulation, Herndon says.

Traditional wood pallets can simply be lifted from the top by vacuum-actuated foam grippers, explained Herndon.

Similarly, Sridhar Karnam, Product Marketing Manager at Adept Technology Inc. (Pleasanton, California) talks about changing pallet configurations. “Pallets are getting smaller. Each production line is not only capable of processing parts but palletizing them for shipment. In the last few years, end-users have been asking for palletizing robotic systems for food packaging applications.”

Robotics and compliant end-of-arm tooling facilitate manipulating products not yet in production nor in the marketplace. “Robotics help in planning for the future for products not in the pipeline yet. We cannot imagine new products to be introduced in five years. Manufacturers need a tool able to handle those future products,” says Herndon.

Beverage case robotically palletized, courtesy Schmalz Inc.Flexible robotics require flexible, adaptable grippers, says William Symanski, an Applications Engineer with Schmalz Inc. (Raleigh, North Carolina). “Universal tools are designed to handle a wider range of products and have better palletizing software. Distribution centers require multiple ways of gripping up to 20,000 SKUs. One tool is able to handle an entire pallet layer of products.”

Grippers must not only deal with a high mix of products that might change frequently, but also extremely irregular shapes, says Lisa Maitre, Senior Project Engineer with Kawasaki Robotics (USA) Inc. (Wixom, Michigan). “Advancements in the of flexibility of robot tooling for palletizing has greatly benefited palletizing applications. New styles of vacuum tooling using foam pads instead of suction cups makes possible the use of the same tool for a broad range of products, including non-uniform products.”

Load, Unload
Increasingly powerful vision systems play an important role in palletizing and de-palletizing applications, especially the latter, says Motley. “Vision plays a big role in guiding the robot in de-palletizing applications. The robot can de-palletize by layer or pick items individually.” Motley says while vision is also used in palletizing work cells, vision is less important due to products having a more well-known location through the use of conveyors and bar codes.

Tom Sipple, Material Handling Product Marketing Manager at the Motoman Robotics Division of Yaskawa America, Inc. (Miamisburg, Ohio) has a similar take on the function of vision in de-palletizing work cells. “Vision does not play much of a part in palletizing but is a big part of de-palletizing. When bringing in layers of product into a de-palletizing work cell, the vision system takes an image to locate products and guides the robot into the ideal position for de-palletizing.” Vision is a powerful part of the solution in de-palletizing applications, concludes Sipple.

Products often shift location on a pallet during transportation, making robotic de-palletizing more challenging upon arrival, points out Robert Rochelle, Food and Packaging Industry Specialist at Stäubli Corp. (Duncan, South Carolina). “Vision is a necessity in de-palletizing operations as product shifts in transit. Vision can eliminate the need for conveyor crowders or to sort a variable product mix on an in-feed sorting device.”

When building a mixed pallet, the robot’s software algorithm should take into account unloading sequences, says Sipple. “Robotic technology can deliver mixed product pallets, although the throughput is not as high as conventional palletizing systems. When putting mixed products onto a pallet, the robot software must consider many factors, such as the ideal unloading sequence, products subject to crushing, stability and how irregularly shaped products can be stacked.” To illustrate his point, Sipple warns against placing canned goods atop of bread.

Skill-Building
Robot users and integrators have several opportunities to educate themselves on palletizing and de-palletizing applications. Adil Shafi, President of ADVENOVATION Inc. (Houghton, Michigan) will conduct a one-hour webinar, Palletizing/De-palletizing-Robot Basics, beginning at 12:00 PM EDT on Thursday, May 24.

“The webinar will cover flexible tooling, hard tooling, mechanical, vacuum, vision and traceability. The webinar will show several application videos of how these things work,” Shafi said in previewing the webinar. “I will present a background of the topic of palletizing and de-palletizing, through application videos, a brief power-point presentation, and a panel discussion.” Shafi will tailor the webinar for both palletizing and de-palletizing experts as well as novices alike. The webinar will look at single product and mixed-load palletizing, order flow and fulfillment, throughput, among other subjects.

Players in the robotics market have another opportunity to find the latest and greatest products in palletizing and de-palletizing applications at Automate 2013. Automate, the premier trade show and conference for all things robotic, is co-located with ProMat at Chicago’s McCormick Place, January 21-24, 2013. These shows promise to be a one-stop shopping venue for manufactures’ automation needs.

“Schneider will show our newer palletizing products, including a high-level robotic palletizer. This system takes up minimal floor space and palletizes at very high speeds,” says Zarnowski. “The work cell is a hybrid of the best attributes of a high-level conventional palletizer and the best attributes of a robotic palletizer: flexibility, speed, compactness, and ease of use that our customers want.”

Several participating companies will have a presence in both Automate and ProMat. “Schmalz will have booths at both Automate and ProMat. We will show universal tooling, systems with a wider work envelope, to handle a wider range of products,” foretells Volker Schmitz, President of Schmalz.

Building an Application
Ergonomic issues of workers lifting and reaching comprise incentives for manufacturers and distributors to consider investing in robotics for palletizing and de-palletizing applications. “Palletizing is a repetitive task, an ergonomic concern. Throughput with a robot is much higher than with a person using a lift assist,” says Maitre.

In a similar vein, Motoman’s Tom Sipple says, “Handling cases over a day means handling a lot of weight. Distributors have great difficulty to get and retain people to work in these conditions. Turnover rates are very high as are the costs of training and retraining workers. Just one back injury can cost as much as one robotic palletizing system.”

Palletizing and de-palletizing applications are a continuing bright spot for the robotics industry. “Palletizing and de-palletizing applications are definitely a growth area. In 2009, the whole robotics industry declined by 50 percent. Despite that decline, palletizing and de-palletizing applications grew by 3.5 percent,” recollects Adept’s Sridhar Karnam. “This application grows by as much as seven percent a year and we see five to seven percent growth in palletizing and de-palletizing applications in the next five years.”

New Trends in Robot and Controller Design

March 8, 2012

by Bennett Brumson , Contributing Editor
Robotic Industries Association
Posted 03/06/2012

Screen image of work cell safety monitoring system, courtesy Kawasaki Robotics (USA) Inc.Without a controller, industrial robots would not be able to perform their application tasks. Controllers contain software giving robots the intelligence to perform complex tasks and provide a means for the robot to interact with the physical environment. Advances in controller design facilitate collaborative robotics, the ability of robots to work in direct interaction with people.

Proposed changes to ANSI/RIA R15.06 robot safety standards guidelines reflect the trend towards collaborative robotics and enable “robotification,” applying robotics into new applications.
“I see a trend towards the robot controller being more of a controller of the whole manufacturing process. With increased processing power, integrators are able to add more items into the robot controller,” says Erik Carrier, Product Engineering Manager with Kawasaki Robotics (USA) Inc. (Wixom, Michigan). “Traditionally, the robot was doing just one task or running one program. Now, controllers have the ability to run multiple programs simultaneously.”

With advancements in controllers, their integration into a work cell becomes easier, says Claude Dinsmoor, General Manager of the Material Handling Segment with FANUC Robotics America Corp. (Rochester Robot transferring exhaust manifolds within a dual check safety zone, courtesy FANUC Robotics America Corp.Hills, Michigan). “Integration makes robots easier to apply, more agile to deal with the increasing demands for robust automation and contributes to the ongoing decline in the cost of robotic systems when compared to traditional fixed automation systems.”

Dinsmoor sees this trend continuing. “We see this trend accelerating with an increasing focus on ease of use of the robot software, increased capability of the robot to do functions normally done by external devices. We also see the dawn of learning robots, machines that learn from experience in executing an application to optimize their performance to become faster, more precise, and more flexible in production.”

More Power, Smaller Package
Controllers have been downsized, a trend that players in the robotics industry expect to continue. “The size of controllers are getting smaller and I expect to see more of that trend in the next five years. Like other electronic devices, robot controllers will have fewer components inside due to consolidation,” says Joseph Campbell, Vice President of ABB Inc.’s (Auburn Hills, Michigan) Robot Products Group. “End-users can now mount smaller controllers above a robot or embed it into the robot. Keeping the footprint small and flexible gives integrators options on where to locate the controller.” Compact robot controllers are very common in the electronic industry, Campbell says.

Likewise, James Shimano, Product Manager with Precise Automation Inc. (San Jose, California) anticipates the persistent shrinking of robot controllers. “I see a continual drive to shrink controllers. In the past, controller cabinets were large, bulky and unwieldy that needed harnessing to the robot. System integrators needed to find a place for the controller and their harnesses while keeping them safe. Controller placement was a problem in an industrial factory, where large and dangerous objects are moving around.”

Shimano notes smaller controllers are necessary for successful “robotification” of research laboratories and life science installations. “In the last three years, the trend towards smaller tabletop controllers and robots in pharmaceuticals, life sciences, laboratories, solar panel assembly and semiconductors has grown. Integrated controllers are smaller in both their computing section, containing the processor and memory, but also the Shield-free laboratory workstation, courtesy Labcyte Inc. and Precise Automation Inc.amplifiers.” Incorporating the amplifier and the controls within the robot’s structure into a very small package eliminates extra cabinets, making controllers more compact, a necessity for tabletop laboratory robotics, Shimano concludes.

Miniaturization facilitates robotic safety in non-industrial applications, Shimano says. “Integrated controllers can create safer robots for use in non-factory settings without safety shields. These controllers are easier to use by people who are not engineers, assembly technicians or scientists who want to use robotics in a collaborative fashion.”

Shrinking controllers is also on the mind of Michael Bomya, President of Nachi Robotic Systems Inc. (Novi, Michigan). “The trend towards miniaturization of robot controllers will continue to the point where integrating the controller into the robot’s arm will be simple and practical. Integrating the controller into the robot arm is a requirement to make a humanoid robot.” Robot controllers will become sufficiently small for placement within the manipulator to advance mobile robots, Bomya says.

Collaborative Robotics
More powerful and miniaturized robot controllers facilitate “collaborative robotics,” enabling people and robots to work in relatively close collaboration within a workspace. “I see new controller platforms allowing for collaborative applications. The robot is only one portion of collaborative work cells and other devices must facilitate it,” says, Carrier. “Proposed revisions to the (R15.06) robot safety standard will help move technology in the direction of collaborative robots.”

Robot manufacturers and integrators are working towards collaborative robotics and some robotic equipment is currently capable of meeting proposed revisions to the R15.06 safety standard, says Charles Ridley, PaR Systems Inc.’s (Shoreview, Minnesota) Material Handling Service Manager. “To meet the new robot safety standard, safety circuits must be dual channeled and dually monitored, with several processors redundantly monitoring each safety circuit. The robot program limits the work envelope, monitors location and speed of the robot by dual processors.”

Ridley illustrates his point by citing a palletizing application. “The robot goes to a certain point within its work envelope to pick up slip-sheets. When slip-sheets need replenishing, safety inputs allow the operator to replenish them without stopping the robot. The robot continues to palletize but safety inputs restrict the robot from going where the operators is.” Ridley adds that controller software recognizes when the palletizing work cell needs more slip-sheets as well as preventing the robot from moving into the area an operator is within the robot’s work envelope.Compact robot controller, courtesy ABB Inc.

Jeff Fryman, Director of Standards Development at the Robotic Industries Association (RIA, Ann Arbor, Michigan) has a similar take as Ridley on the role of collaborative robotics. “The robot is in automatic mode during collaborative operations and the robot stops for the collaborative operation. Collaboration operation allows work cells designed without fixtures and simply drives the robot to a starting point.” The operator then commands the robot to execute a pre-programed operation.

Fryman recalls a demonstration of hand-guided collaborative operation at the Automate trade show in March 2011. “At Automate 2011, a simulation of a water-jet cutting work cell was demonstrated. A 150-kg capacity robot stopped and waited for the operator to maneuverer it within the work cell. The operator would then exit the collaborative work space and return the robot to its fully automatic mode, where the robot would cut out a predesigned pattern without the use of fixtures,” Fryman said. “Grabbing a robot by a joystick on the wrist plate and driving it around is impressive.”

Continuing, Fryman says, “Collaborative robots can assist the operator by doing the heavy lifting so the person can focus on the thought processes. Controller designs have built-in safety-rated features to assure the robot will do exactly what it is told to do and stop when it knows it did not.”

While the robot controller and its software makes the work cell more predictable, human nature remains unpredictable. “The difficulty with collaborative operation is that human operators do not always perform in a Graphical representation of a collaborative robotic system, courtesy Motoman Robotics Division of Yaskawa America Inc.controlled or reliable fashion so safeguarding can be a challenge. The revised safety standard will require a risk assessment to address the potential hazards of a particular installation,” says Chris Anderson, Welding Technology Leader with the Motoman Robotics Division of Yaskawa America Inc. (Miamisburg, Ohio).

Brandon Rohrer, Principal Member of the Technical Staff at Sandia National Laboratories (Albuquerque, New Mexico) agrees with Anderson’s assessment. “I am watching the trend of enabling robots to behave well in unpredictable, unexpected, and poorly modeled environments. Traditional assembly line robots work really well as long as the lighting is just right and everything coming down the conveyor belt is oriented the same way. If circumstances deviate too much from design conditions, the system chokes really fast. New developments in controllers are pushing back those limits on how structured the environment must be.”

The notion of ridding work cells of hard stops intrigues John D’Silva, Marketing Manager with Siemens Industry Inc. (Norcross, Georgia). “The revised R15.06 robot safety standard could possibly do away with hard stop requirements in new robots, with better control of restricted space. Collaborative robotics is a way of the future because both the robot and operator can work in harmony to increase production. Reliable safety is provided by the safety controller during operation, setup and commissioning phases of the work cell.”

Both Fryman and D’Silva pointed out that proposed revisions to R15.06 relating to shield-free work cells will be applied to new robotic systems and retrofitting current systems will not be an option for end-users.

Robotification
Advancements in controllers will help lead robotics into new applications. “Controller technology continues to open new applications for robots, especially in non-traditional areas, such as where either people or custom machines are normally applied, such as surface finishing, on-the-fly weight measurement, and precision assembly,” says Dinsmoor.

Similarly, John Boutsikaris, Senior Vice President of Adept Technology Inc. (Pleasanton, California), says, “Traditional applications will continue to expand with new gripper technology and continuous performance improvements. Fusion of sensory inputs including sonar, scanning lasers, three-dimensional vision systems and more, on the robot controller continue to expand the applications for robots into more flexible, dynamic Robotic work cell motion controller, courtesy Adept Technology Inc.environments.”

As controllers become more powerful, they will become more capable of managing other equipment and facets of the work cell, says Amy Peters, Business Planning Manager with Rockwell Automation Inc. (Milwaukee, Wisconsin). “End-users want tighter integration with the logic platforms, built-in kinematics, and the ability to control other aspects of a manufacturing plant.”

Joe Campbell believes “More intelligent controllers and enhanced safety circuitry allow robots to work in closer proximity to people and opens many new applications. I see growing opportunities where multiple robots in a work cell function in a very coordinated fashion.” Campbell also anticipates robots working outdoors. “I see manufacturing outside and robots aboard ships performing maintenance and repair of ship components as well as on oil rigs with controllers able to withstand the weather.”

Motoman’s Greg Garmann, Software and Controls Technology Leader says, “Robot controllers have all the tools required to jump into almost any new application. The only restraints are the imagination of programing engineers and the complexity of the task.”


RIA Members Explore Methods of Robotic Palletization

February 2, 2012

Occam’s Razor suggests that sometimes the simplest answer is the best answer. However, as industry professionals know, in the world of robotics it’s just as often that the easiest solution is not the best solution. In the case of Consumers Co-operative Refineries Ltd., the standard robotic vacuum palletizing system wasn’t going to work with their product. In order to solve CCRL’s palletization predicament, RIA Integrator Flexicell manufactured a different system of palletization.

Robotic Palletizing is a Slick Operation

Jack Mans, Plant Operations Editor — Packaging Digest

After investigating conventional palletizers, the company decided to go to a robotic system. Their palletizing system needed to be capable of handling two different products-cases and 5-gal plastic pails-simultaneously.

The robotic palletizer handles different size cases and 5-gal plastic pails— simultaneously. When changing case sizes, the operator selects the proper case size from the menu on the HMI, which adjusts the individual vacuum zones to match the case size.ereas cases are typically picked up by vacuum because their surfaces are flat, the pails have multiple fixtures on the lid, which disrupt the vacuum. This meant that another method would have to be used, such as mechanical jaws.

Also, the cases come in varying sizes. While only one case size runs at a time, CCRL could not afford any downtime between different products. A changeover had to happen quickly, meaning that the robot’s gripper needed to handle different case sizes on demand, while still being capable of moving the pails. This flexibility required a sophisticated end-of-arm tooling (EOAT) design.
