In December 2021, a wierd creature started working round Audi factories, serving to them to arrange for the long run.
Spot, a robotic canine developed by Audi and NavVis, a German startup, carries a 3D laser scanner that information photos of each instrument and sq. meter. The pictures might be fused to create a digital twin of the manufacturing facility that can be utilized to plan manufacturing, change tooling, and notice a bunch of different effectivity beneficial properties and price financial savings.
As a result of Spot can work weekends with out grievance and doesn’t want breaks, he can scan a complete manufacturing facility in 48 hours, a job that may take a workforce of individuals three weeks.
“Merging all of the planning information in our digital twin has given us a holistic have a look at our future manufacturing plans years forward of time,” stated Andres Kohler, head of Audi’s digital meeting planning workforce.
Spot, a check undertaking, could also be just a few years forward of his time — most automakers are counting on different scanning strategies to digitize their factories — however digital twins are rising as a key to quick, secure and environment friendly manufacturing, particularly as automakers race to maintain up with developments corresponding to electrification and the software-defined automobile.
Utilizing twins, automakers can sport out the conversion of an internal-combustion manufacturing facility to construct electrical automobiles. They will test-fit a brand new piece of tooling, practice staff in new processes, and modify these processes on the fly to enhance through-put charges and even automobile high quality.
“When you’ve a digital twin, you are able to do issues within the digital world earlier than the pricey dedication to doing it within the bodily world,” Richard Kerris, vice chairman Omniverse platform improvement at Nvidia, advised Automotive Information Europe. A real-to-reality digital twin, all the way down to the final nut, bolt, course of and employee of a manufacturing community can provide an automaker “superpowers,” he stated.
Nvidia is working with BMW, Basic Motors, Mercedes-Benz and others on its Omniverse platform, which Kerris describes because the working system of an industrial metaverse. He rapidly added that “metaverse” in an industrial context “just isn’t all people floating round as avatars,” however somewhat a community that enables seamless connectivity between 3D digital worlds.
“The important thing factor a couple of digital twin is that it doesn’t cease once you’ve made it,” Kerris stated. “Over time you may examine and be taught issues — possibly there are methods to coach robots to maneuver extra effectively or safer methods to maneuver round tools.”
Digital twins and the broader idea of an industrial metaverse construct on the ideas of what’s often known as Trade 4.0, which goals to construct higher processes via information assortment (the Web of Issues) and processing.
“The primary wave of Trade 4.0 introduced transparency and a few predictiveness, nevertheless it didn’t actually mix real-world information and the aptitude to simulate,” Pierre Bagnon, vice chairman, international head of clever business accelerator at Capgemini, advised Automotive Information Europe. “There are nonetheless lots of silos.”
Within the automotive business, digital twins can break down the partitions between product improvement — the area of designers and engineers — and course of engineering, the place automobiles go from prototype to manufacturing, stated Bagnon, who labored at Robert Bosch for greater than 15 years.
“What we dreamed of was an ideally production-friendly product design,” stated Bagnon’s colleague Matthias Eisenschmid, vice chairman, head of automotive manufacturing and provide chain administration, Capgemini Invent Germany, and a veteran of manufacturing planning at Mercedes-Benz. Digital twins are a “sport changer” for this use case, he stated, permitting product and course of to develop in a synchronized, parallel approach.
“You get a manufacturing line that’s mature proper from the beginning,” Eisenschmid stated. “Up to now you had to spend so much of money and time in bodily manufacturing to ramp up and optimize the processes. Utilizing an industrial digital twin, you may establish and clear up most of your issues upfront within the digital part.”
Digital twins can shorten time to market by 20 to 30 %, enhance high quality by 20 % and useful resource effectivity by as much as 40 %, Bagnon and Eisenschmid stated. “That’s the magnitude of ambition that our shoppers are putting in to justify the funding,” Bagnon stated.
“It’s a multimillion-dollar funding, however the extra essential query is what is going to occur in the event you don’t do it?” Eisenschmid stated. “There are new rivals who’re already taking vital benefit of those new applied sciences as widespread instruments.”
Renault Group is creating its personal industrial metaverse together with digital twins, a four-step, years-long course of. “We wish to have a completely actionable universe with a full reproduction of what’s occurring in the true world,” Eric Marchiol, director of digital transformation at Renault Group, advised Automotive Information Europe.
“We have now discovered that huge information utilization is the ‘killer app’ to realize our targets,” Marchiol stated.
Renault has formidable targets: By 2025, it expects to see total financial savings of 320 million euros, stock financial savings of 260 million euros, a 60 % discount in automobile supply time and a 50 % minimize in manufacturing CO2 emissions. On the standard aspect, will probably be a significant contributor to a 60 % minimize in guarantee prices.
However Renault’s path to a full industrial metaverse factors to the scope of such a undertaking.
Step one, information assortment and standardization, began in 2016 when Renault constructed its personal apps to have the ability to visualize present information on the store flooring on pill computer systems, which led to some “fast wins,” Marchiol stated. It then created an inside workforce to “crack what’s inside” programable logic controllers, robots and “black bins” in different tools.
With 10,000 robots throughout the group from totally different suppliers corresponding to Comau or Kuka, in addition to equipment that dates again many years, “we had an enormous variety of information,” Marchiol stated.
Now, he stated, Renault can collect information from its tools in a standardized approach — and it’s receiving a billion information units a day. “Nevertheless it’s not sufficient in the event you solely accumulate from tools as a result of we nonetheless have lots of guide operations,” Marchiol added. To seize this information, Renault has constructed digital workstations that monitor human actions.
Within the second step, Renault is creating digital twins of its factories utilizing expertise from Siemens and Dassault to simulate new tools, and it’s scanning its present vegetation all the way down to the final millimeter. Renault then has an avatar it might probably use for tools setup coaching or ergonomics.
Subsequent, Renault is monitoring all outbound and inbound actions from suppliers, “so we all know precisely the place each truck is,” Marchiol stated. This extends Renault’s information ecosystem outdoors its personal industrial footprint.
Within the fourth step. Renault will leverage the ability of its industrial metaverse throughout the group via cloud-based, easy-to-use analytics instruments. “We’re democratizing the usage of massive information instruments inside all our operations,” he stated.
Digital twins and different components of the metaverse are crucial to Renault’s shift to electrical automobiles and powertrains, which might be constructed underneath the Ampere spinoff in a bunch of vegetation in northern France referred to as ElectriCity.
“After we are beginning new processes for an electrical motor or battery, we will’t take six months to achieve full capability or course of optimization,” Marchiol stated.
He expects Renault to have a completely practical metaverse inside two years, with the ultimate step closing an computerized suggestions loop to permit parameters of kit corresponding to robots or presses to be modified utilizing digital twins.
Such twins are already getting used to mannequin new manufacturing traces, together with programming robots and performing security checks in digital actuality, “earlier than spending even 1 euro,” Marchiol stated.
Renault has discovered that information assortment can result in surprising breakthroughs.
“We began with the concept that we might save some huge cash with predictive upkeep, and we did, however it isn’t the most important moneymaker,” Marchiol stated. “If you begin gathering information from all of your tools and develop consistencies within the course of, you’ll be able to see the elephant within the room you weren’t in a position to see earlier than.”
For Renault, that features high quality points within the bodyshop that may be traced all the way down to the extent of a selected weld, or a course of delay by a selected robotic on a automobile configuration that may come down the road solely as soon as each three hours.
“The identical information that can be utilized for predictive upkeep can be utilized for high quality or power utilization,” Marchiol stated. “Every time we add tools, we don’t have to ask ourselves, ‘Do we have to accumulate information?’ It is an computerized coverage.”
Added Marchiol: “We have now opened the field on the metaverse, however we have to implement it in all places with extra capabilities.”
Different automakers are relying on digital twins to drive efficiencies, innovation and price financial savings. GM, working with Basic Electrical, has developed what it calls a Digital Manufacturing unit Testbed to mannequin processes for build-to-order manufacturing; digital twins additionally check the mixing of bodily and knowledge techniques on the plant flooring.
Mercedes, which Kerris described as one among Nvidia’s “lighthouse” clients, will work with the provider to construct a digital twin of its manufacturing facility in Rastatt, Germany, the place it is going to produce full-electric “entry-luxury” automobiles on the forthoming MMA platform beginning in 2024. Utilizing a digital twin, Mercedes can check the implementation of the platform and its tooling and processes with out disrupting present manufacturing.
BMW, like Mercedes, is counting on digital twins (and dealing with Nvidia) because it prepares its manufacturing facility community to construct full-electric — in addition to software-defined — automobiles. Its iFactory mannequin goals to “make planning and simulation of all processes and all the manufacturing system one hundred pc digital,” the automaker stated final June.
“Manufacturing planning can combine the digital product into the digital manufacturing facility at an early stage,” Michele Melchiorre, BMW’s head of manufacturing system, planning instrument store, plant building, stated in a launch. “This reduces planning effort and capital expenditure and, on the identical time, ensures processes are extra environment friendly and extra steady throughout ramp-up.”
BMW’s manufacturing facility in Regensburg is now totally digitally mapped, and its digital twin is getting used for planning future plant buildings and configurations. Different BMW vegetation with digital twins embrace its U.S. manufacturing facility in Spartanburg, South Carolina, and its Munich facility.
BMW stated it might full the digital scanning of all its vegetation by “early 2023,” in partnership with NavVis, which except for Spot the robotic canine, focuses on cell laser scanners that operators strap to their physique as they transfer across the manufacturing facility flooring.
“We’re heading within the path of a real-time visualization of your manufacturing facility,” stated Phillip Quadstege, senior answer supervisor digital manufacturing facility at NavVis.
NavVis scanners seize shop-floor tools in its precise place, but in addition the bodily area round tooling as much as the ceiling. That may decide how a lot area stays for brand new tooling, which is essential if automakers wish to develop output.
New tooling comes customary with its personal digital illustration, Quadstege and different consultants stated, however older tools must be scanned piece by piece.
“Many of the information the businesses have is very outdated,” he advised Automotive Information Europe. “Quite a lot of corporations nonetheless work in 2D.” Even new tooling must be scanned as soon as in place, he stated, as a result of a web site plan may differ from the precise set up, making the digital twin inaccurate.
As soon as a plant is scanned, NavVis creates a digital twin utilizing cloud expertise.
Quadstege says transparency –the potential for anybody, wherever inside an organization to see what is occurring in a manufacturing facility which may be 1000’s of miles away — is the important thing enabler of advantages from digital twins.
“There may be lots of potential in the event you introduce transparency,” he stated. “You may cut back funding; product high quality goes up; you’ve effectivity beneficial properties in planning.”
As a result of factories compete towards one another for automobile allocations and funding, such transparency may very well be seen as a risk, he stated. “Plant managers fear about their plant compared to others,” he stated. “However then again, you may’t keep away from digitalization.”
