Cobots as Force Multipliers
Is Disruption Ahead for the Cobot Revolution?
Does the cobot revolution need the revolution of e-commerce to drive wide-scale adoption?
“Once we cowork with robots right next to us, it’s inevitable that our tasks will bleed together, and soon
our old work will become theirs—and our new work will become something we can hardly imagine.”
–Kevin Kelly, The Inevitable: Understanding the 12 Technological Forces That Will Shape Our Future
Cobots embody the dream ideals that every SME wants in any worker—machine, human or otherwise—minus the frictions of retiring workers, firings, resignations, recruiting and training that cost U.S. employers a whopping $630 billion annually, according to a labor market friction study by ARK Management.
Similar frictions plague every major developed economy from Asia to the Americas. Billions that in a very real sense could otherwise be diverted into more automation tech.
A new class of shiny, energetic and robust job candidate is showing up and acing interviews seemingly everywhere these days, and they are turning out to be, according to their employers, the best new hires any small factory or warehouse owner could ever have imagined.
Not bad for a bunch of job seekers that are machines.
Tack on HR friendly, low upkeep, fast learner, flexible, easily redeployable, and sporting a more than pleasant payback, and you’re looking at what has now taken on the proportions of mega-boom in the deployment of industrial robots, the so-called cobot revolution.
Cobot technology has disrupted traditional robotics, however, is this nascent revolution itself ripe for disruption and might the adoption of e-commerce crown the ultimate winners?
Cobots, as tireless force multipliers, answer lots of questions for manufacturers from payroll relief to worker acquisition to workplace injuries to elevating total productivity and more.
In the U.S., where robots in general witnessed a 15 percent increase in sales (2018), penetration into the assembly industry, for example—where cobots are an ever-growing segment—enjoyed a remarkable leap of 61 percent, in just one year!
The chart above in the header, Inkwood’s Global Collaborative Robots Market Forecast 2019-2027, displays the rapid growth phase for assembly along with packaging, material handling, machine tending, and quality testing. And with every robot there comes a need for robot parts –components! Controllers, drives, and sensors are experiencing record production that is headed much higher through 2025.
However, cobot sales figures thus far are a pittance when compared with the size of the addressable market. According to a company spokesperson, category leader Universal Robots (UR), has an installed worldwide base of approximately 30,000 as of December 2018 (That would up the tally some 16,000 more deployments since UR’s 2015 acquisition by Teradyne).
No other cobot manufacturer is even close to that many deployed collaborative machines. Considering that the U.S. alone has over 250,000 manufacturers, and China four times that number, the proverbial tip of the iceberg has barely been addressed by cobots.
And that’s just for manufacturing; logistics is also experiencing its own cobot revolution with “mobile” cobots.
Mega-shipper DHL is working with Locus Robotics’ mobile cobot transporters to move packages through its warehouses. Still others, with cobot arms aboard mobile platforms, combine “picking and transport”.
Cobotics World’s article, Cobots and AGV: the perfect synergy for smart factories! cites these leaders in the “piggybacked” world of dual AGV/cobot developers:
- Bosch APAS
- Staubli Helmo
- KUKA KMR and flexFELLOW
- Aubo JR2
- F&P Lio
- Siasun HCR20 and HSCR5
- Techman Mobile Series
IDC forecasts that by 2018 , “45 percent of the 200 leading global e-commerce and omni-channel commerce companies had deployed robotics systems in their order fulfillment warehousing and delivery operations.”
Although there’s a galaxy of potential awaiting mobile cobots in logistics, it is stationary cobots helping to make things in factories, especially with SMEs, where cobotics is roiling with unprecedented activity.
Some three dozen cobot makers, as either startups, newbies, or established robot manufacturers, are all rushing into the marketplace, mostly over the past five years. Undoubtedly there are three dozen market studies stuffed into the business plans for each of these contenders that forecast a cobot colossus on the rise; and they are all correct. It’s happening right before their eyes.
For market sizing, Jürgen von Hollen, president of Universal Robots, says he uses data from “four or five research companies” to make projections, concluding that a cobot market of $180 million “to be at least $2 billion by 2020.” Loup Ventures sees a ~$9.2 billion market by 2025. That’s an annual cobot marketplace of between 100k and 400k machines. For a little perspective, FANUC, the world’s largest robot maker, has an installed base of industrial robots (all models) of over 400k.
In short, the cobot colossus is very real. Universal Robots (UR) has the lead, but thirty-plus robot makers have jumped into the cobot fray and are on the hunt.
To date, although a rising powerhouse for manufacturing and logistics, worldwide sales of cobots are a miniscule 3 percent of the total sales for industrial robots, according to the International Federation of Robotics (IFR): Total 2018 sales of industrial robots: 422,271.
Ideal form factor
Amazingly, even a cursory look through UR customer feedback wows with glowing customer testimonials, case studies, and scads of videos extolling the look and feel of the machine. Like dreaming up the ideal form factor for a laptop with the best UI/UX design all at once, the Danes have clearly hit upon a winning form factor their first time out.
UR users put the compact machines just about anywhere—even inverting them to work upside down in tight spaces with other URs. Plus, the range and variety of tasks that the machines have been put to expands seemingly on a daily basis. Most other cobots simply can’t pull off the same gyrations, uses, and engineering. Such are the hallmarks of a great machine; one that has also swept the field in popularity and sales revenue, especially among SMEs—the sweet spot for cobot sales.
A quick look through the Cobotics World catalog of 150 different cobot models shows nearly half of the competing cobot makers have elected to develop a single, multi-axis cobot arm with a similar or exact form factor to that of UR. There seems to be a bit of wisdom in doing so, what with UR so wildly popular, selling so well, and in top-of-mind awareness with so many potential cobot buyers.
Critical mass in public awareness is all about the UR arm.
Of the nearly three dozen cobot makers, here are the world leaders, according to Interact Analysis (see chart below): a group from which may emerge very popular machines for certain niche specialties, and maybe as well, a few true cobot stars equal to or greater than UR:
Contemplating “The best sandwich at the best price”
At the Gerenga exhibit booth at Bangkok’s Intermach Show, a Thai engineer and business owner, a manufacturer of refrigeration and cooling equipment, stood eyeing a Universal Robots UR5 that sold for $35k. He said that he’d seen every robot at the event, and none impressed him more than the UR5. When asked why, he simply replied: “It’s the best sandwich at the best price.”
Interesting way to think about value and price. Nevertheless, it’s what everyone does when contemplating the purchase of anything.
But is the UR5 the best sandwich at the best price?
That it’s probably the best sandwich tech-wise is arguably borne out by end users who have bought a UR5, and swear by it.

The $35k question
But is $35k the best price…and is price ultimately the deal maker or breaker in cobot sales, which seems to be the case?
The Robotiq website has an interesting page appropriately called: What is an Average Price for a Collaborative Robot? BTW: Robotiq does not make cobots; it solely manufacturers grippers and gripper accessories. “When you are shopping for a robot,” begins the page, “one of the first things you want to know is the pricing of the robot, its tool(s) and all the accessories.” The page is a no-frills, commonsense look at bottom-line total cost of ownership for a cobot, which Robotiq pegs at three times the purchase price.
The $35k best sandwich is then, according to Robotiq’s estimate, three times its cost or $105k.
Robotiq’s times three actually lines up pretty well with the estimate from Ron Potter, Director of Robotics Technology for Factory Automation Systems: “In an integrated turnkey system, often the robot is maybe one-third of the cost of the total installation.”
Can the cobot revolution be dominated for long by a machine that costs $105k to own?
The AUBO i5, for example, which looks like the UR5’s identical twin painted orange (see photo comparison), has some major differences under the hood.
AUBO Robotics claims the i5 is faster and more accurate than the UR5…and costs, get this, $10k less than the UR5. A little more easy on the wallet at $25k.
That’s price-performance disruption of a major kind.
“The era of cobots being unable to deliver the accuracy and efficiency of industrial robots is over,” said Dr. Wei Hongxing, co-inventor of the AUBO i5 as well as chairman of AUBO Robotics, in an interview in December from Shanghai.
Increased speed of operation is a big plus, since slow is the bane of most cobots everywhere. Dr. Wei pointed out that AUBO’s speed and accuracy are particularly big plusses for the 3C industry (computers, communications, and consumer electronics).
Since China produces most of the world’s electronics, including seven of every ten mobile phones, a 3C-friendly cobot is a big leg up in automating electronics production.
Such potential spurred $9 million in Series A funding from China’s Fosun Group, which forecasts AUBO taking 30 percent of the local market.
The investment will expand AUBO’s R&D efforts as well as expand production from its new factory an hour’s drive outside Shanghai.
Dr. Wei says the plant could ramp up to 5,000 units fairly quickly. The company has aspirations of producing 30,000 units annually over the next three to five years.
Of course, the big news for buyers is the price tag—$10 grand less than the UR5! Applying the three times rule, the machine rings in at $54k instead of $105k. Big difference.
Might the presence of cobots in e-commerce drive cobot prices down and spur faster, wider adoption?
Reinventing Productivity with Cobots
The Promise of Cobots…Delivered!
Initially dismissed as a non-factor, this brilliantly-conceived robot arm has turned the robotics industry on its head. Now, a cobot is a must-have in every robot maker’s product line, or else!
