Including robots or cobots into your manufacturing processes begins with nice-list choices, equivalent to model forms and cell placements. Choices about cease-of-arm tooling (EOAT) are appropriate as major and potentially must be revisited as SKUs trade or technology improves.
Some applications dictate definite EOAT choices, admire a robotic arm conserving auto physique parts in articulate all the design in which by means of welding operations. The arm nearly completely mounts gripper-sort EOAT. A cobot arm worn for decide-and-articulate operations, on the diverse hand, might perchance presumably mount either a vacuum-primarily primarily based mostly gadget or a gripper, reckoning on the size of the part and placement error tolerance.
Abnormal Makes exhaust of for EOAT Know-how
There are diverse frequent applications for EOAT besides heavy industrial meeting, decide-and-articulate, and palletizing/depalletizing. “Machine tending has to be one in every of the largest patrons of EOAT, with so many alternative forms of parts to machine, the flexibility and customization of EOAT essentially shine in this industry,” says Beau Wileman, Utilized Cobotics program manager at PBC Linear.
The food and beverage industry helps drive EOAT pattern as a consequence of the lightweight and tranquil composition of the manipulated objects. Vision programs drive one other fluctuate of EOAT picks.
“Equipping a robotic or a cobot with a multifunctional gentle and a camera can allow the gadget to originate a lot of inspections, from new presence/absence detection to photometric stereo implementations for tire inspection, without needing to trade the sunshine to search out the optimum illumination setup,” says Steve Kinney, director of practising, compliance, and technical alternate suggestions for Natty Vision Lights.
Abnormal EOAT Concerns
“Basically the most important components to make contributions [to EOAT selection] are workpiece geometry, venture budget, and quantity of a given workpiece,” says Wileman.
“The largest ingredient when selecting an EOAT for a particular utility is what needs to be picked within the utility — namely, the frequent size, the maximum size, the minimal size, the tension, and the sturdiness of the product,” says Anthony Romeo, product marketing manager at Gentle Robotics.
“The cease-of-arm gadget needs so as to grip or screw, reckoning on what model and the persona of the utility. The gadget needs to set it [right] 100 cases out of 100,” says Kristian Hulgard, new manager of Americas at OnRobot.
Hulgard adds, “Then I non-public the worth of redeployment and straightforward integration. Of us are wanting so as to exhaust their robots for a lot of things, or no longer no longer as a lot as maintain a future-proof cease-of-arm gadget that doesn’t essentially hasten on the shelf within the event that they’re desirous to exhaust the robotic for something else.”
A worn pneumatic gripper has a restricted sequence of capacity parts of diverse sizes, shapes, and materials compared with an electrical servo-driven gripper that contains bigger flexibility, says Hulgard. The pneumatic gripper has a noteworthy decrease value level, however every unique SKU also can require an entirely unique pneumatic gripper, whereas an electrical servo-driven model might perchance presumably contend with a nice sequence of SKU modifications.
Recent EOAT Know-how Tendencies
“EOAT technology is trending toward streak and yield improvements. Offering a customer with an EOAT that is faster or extra first price goes a prolonged methodology to helping their total operation. Being ready to commence/shut an EOAT a fraction of a second faster can end result in indispensable savings over the direction of a shift,” says Romeo.
“Moreover to the flee increase, EOAT designers are increasing shiny ways to extend yield by making sure no product smash. The exhaust of comfy grippers or offering extra factual decide coordinates are about a examples of accelerating yield,” Romeo adds.
“I am seeing a big shift to electrical/collaborative grippers that operate barely about a easy gadget to without considerations interface with the robotic/cobot,” says Wileman.
Hulgard believes plug-and-play gadget holds the most effective solution for producers to outlive the rising sequence of robotic deployments without hiring a bigger sequence of robotic engineers to contend with EOAT installations and changeovers.

“By deciding on a decide-and-articulate gadget controller pre-vetted by producers, whether or no longer it is your cease-of-arm gadget, your sensor, your camera, your conveyor, or whatever it is also, you dramatically slash again your deployment time,” Hulgard adds.
“In the food industry, where labor prices are rising, turnover is high, and extra rigorous food safety standards are required, improved automation technologies equivalent to 3D imaginative and prescient, synthetic intelligence, and comfortable grippers surpass existing EOAT alternate suggestions,” says Romeo.
“When compared to worn alternate suggestions, that are in overall too pricey, advanced to place in force, and require custom-made pattern, the unique generation of robotic-primarily primarily based mostly automation provides a indispensable competitive edge every technologically and economically,” Romeo adds.
Pressing Challenges for EOAT Style
“As robots discover effectively at supplying utilities to the tip of their fingers, EOAT advantages by having a smaller and extra compact form ingredient. The venture in EOAT is limiting the size whereas conserving the energy score of the robotic for the workpiece,” Wileman says.
Hulgard believes that producers maintain already received the tooling alternate suggestions they must contend with any direction of. He says that value-effectiveness and ease of exhaust, no longer gadget produce, are the principle challenges for EOAT technology. “If now we maintain to exhaust too many engineering hours on every venture, we’re no longer going so as to fulfill this request for manufacturing robotic installations. But when we can beget it essentially easy and integrable that the customer might perchance presumably even be ready to set it himself, then we’re within the factual space. That is the largest venture,” Hulgard says.
3D Printing Enables Unusual EOAT Selections
“At PBC Linear, our product line of sizable-form 3D printers has allowed us to diagram aid up with some attention-grabbing EOAT geometries to accommodate advanced contours in our parts,” says Wileman. “3D printing remains one in every of the final word ways to form (or no longer no longer as a lot as prototype) rapid EOAT alternate suggestions for prime-mix or high-quantity stores.”
Duygu Gunay, product manager at HP 3D Printing, has the same opinion, noting that “additive manufacturing has a chain of key advantages over worn manufacturing systems, which is leading extra companies to embrace the technology. From rapid prototyping, taking into memoir a vastly diminished time-to-market for products, to 3D printing’s skill to drive efficiencies within the present chain, for a lot of companies additive manufacturing is an evident alternative by methodology of building custom-made EOAT.”
Sodecia, a corpulent-service provider of parts for automotive vitality put together, safety, and internal segments, plus diverse instruments and equipment, makes exhaust of robotic fingers broadly in its manufacturing operations, as an illustration to contend with parts all the design in which by means of welding applications. Sodecia collaborated with HP’s 3D printing physique of workers to supply a novel aluminum cease-of-arm gadget with diminished weight to permit faster cycle cases.
The unique instruments are modular, adjustable, and adaptable for smaller robots owing to the lowered weight. They also design less vitality, maintain a smaller footprint, and commence the door for unique applications, equivalent to integrating space welding cap-altering devices without prolong into the gripper.
Hulgard thinks the present kind of 3D printing for EOAT optimization distracts from the purpose that robotic integrators must space for themselves.
“It appropriate tells me that they’re focusing on specifications and stats of their EOAT. The explanations why I’m no longer going that route is I mediate it is extra attention-grabbing to discuss about … what cost the gadget creates for the market and for the customer going forward,” says Hulgard.
“We can always fight about who can grip the hardest and maintain the final word payload or be the lightest weight. … To me it is fully beside the level. We’ve the technology to grip something else we desire, to screw any screw. … We’ve gotten up to now. Now now we maintain to beget it extra treasured for the customer. We must beget it more straightforward to mix,” Hulgard adds.
EAOT Tendencies to Seek for For
“I see EOAT getting smarter and taking on extra and extra safety and size capabilities —weight, size, imaginative and prescient (hasten/no hasten), space scanning, and so forth.,” says Wileman.
“Interior five years … all the pieces will seemingly be one unit: the robotic, the tip-of-arm gadget, the stand, the utility, the sensors. Every little thing will seemingly be unified into one kind of gadget where we can set up monitoring, management, programming, all the pieces, so you do no longer differentiate the actual robotic from the EOAT. It is miles suitable going to be one solution,” says Hulgard.
“With the most as a lot as the moment increase in AI, I see EOAT technology using machine imaginative and prescient and AI recordsdata to beget faster and extra factual picks. Rate and yield drive many technologies, and EOATs don’t seem like any exception. More intelligently working out what is being picked and the fastest methodology to come to a decision this can also aid customers increase their bottom line,” says Romeo.
