Building Amazon a Better Warehouse Robot 108

Nerval's Lobster writes: Amazon relies quite a bit on human labor, most notably in its warehouses. The company wants to change that via machine learning and robotics, which is why earlier this year it invited 30 teams to a "Picking Contest." In order to win the contest, a team needed to build a robot that can outpace other robots in detecting and identifying an object on a shelf, gripping said object without breaking it, and delivering it into a waiting receptacle. Team RBO, composed of researchers from the Technical University of Berlin, won last month's competition by a healthy margin. Their winning design combined a WAM arm (complete with a suction cup for lifting objects) and an XR4000 mobile base into a single unit capable of picking up 12 objects in 20 minutes—not exactly blinding speed, but enough to demonstrate significant promise. If Amazon's contest demonstrated anything, it's that it could be quite a long time before robots are capable of identifying and sorting through objects at speeds even remotely approaching human (and thus taking over those jobs). Chances seem good that Amazon will ask future teams to build machines that are even smarter and faster.

    Amazon's contest demonstrated anything, it's that it could be quite a long time before robots are capable of identifying and sorting through objects at speeds even remotely approaching human (and thus taking over those jobs).

    This is from the summary, and it is wrong.

    It implies that it will be awhile before the robots are as fast as humans and thus replacing their jobs.

    This is not it at all. The robot doesn't have to be faster than humans, just cheaper. If the robot can only handle 12 items in 20 min, but it costs 50 cents an hour to run, then you can simply order up more robots.

    ---

    I was watching a show on The Discovery Channel recently that was profiling new robots, and one of them is a new learning robot that you teach to do things by just showing it. It isn't fast, it takes maybe 5 minutes to fold a shirt for example, but you can teach it to fold a shirt by just showing it, the same way you'd show another human. Make some adjustments and corrections as it tries to do it and then it has "learned" how to do it. That robot costs just $30,000 to purchase and is expected to last for years. It can also be taught how to do other things.

    It doesn't have to be fast if the job is one that you can scale up and just buy more robots, that robot will work 24/7/365, it never calls in sick, it never asks for a raise, and it doesn't complain about working conditions.

    ---

    Amazon ships stuff from warehouses, it can simply order up 500,000 such robots if needed.

    • Not to mention if the robot has the dexterity necessary you could deploy them now and the picking algorithm is a software upgrade pushed out in the future. It's not like the hardware probably will need much of an upgrade.

      • Yep, once the hardware is in place, I imagine the software will do nothing but get better over time.

        Companies like Amazon have all the incentive in the world to make it work, and they aren't alone. There are thousands of other companies that also need to make this all cheaper and more reliable.

        That is a Google Search of "Newegg Warehouse" and I clicked on images.

        Some of those are not of Newegg of course, but many are. This is a huge problem to solve...

        As well, it's mostly a compute power problem but in production quantities using commodity hardware, the mechanical components will dominate the cost. So, upgrading the electronic bits once (or maybe twice, but mechanical stuff wears out and at some point you will want new sensor feedback from the mechanical bits so there is a limit here) might expand the life at low cost of such robots.

    • Humans only have = two hands, and they take up a fair amount of vertical space too. Stack the picking arms 10-20 high, build a conveyor belt that can bring shelves to them and they start to look much more interesting. Sure each robot may take a minute to pick one item. But this is an embarrassingly parallel problem.

      • But this is an embarrassingly parallel problem.

        Yep, the idea that we'll continue to employ hundreds of thousands of people in warehouses for hundreds of companies in 10 to 20 years is just silly.

        Clearly they'll get replaced in one form or another. Oh sure, you'll need a few people to run the machines and a few people to build or repair them, but you won't need hundreds of thousands of them.

        And of course the people losing their $10/hr jobs at Amazon aren't the people who will build or repair these robots.

        • A basic minimum income would surely relieve the sting of having physical labor made obsolete.
        • I does make me wonder what we're all expected to do for a living in 20-30 years. We're seeing automation on every horizon, and just about every job I could think to get is endangered in the foreseeable future. How are people supposed to buy things when everyone is unemployed?

    • that robot will work 24/7/365, it never calls in sick, it never asks for a raise, and it doesn't complain about working conditions.

      Bah, you should upgrade to internet connected robots. That way they can call in when malfunctioning, or when their working conditions are inefficient.

    • The effect of 'contests' and 'rewards' is often a bunch of people coming up with an expensive one-off stunt that does exactly what is required for the prize money and nothing more, and does not really advance the state of the art. The various turing test contests are an example, as well as the Ansari X prize.

      I agree with you, but not completely. For contrast, the Darpa grand challenge led to Google's self-driving car, which is poised to put 3 million truck drivers out of work.

      The original grand challenge might actually be the problem - people looked at the success and tried to emulate it.

        Go back 115 years ago and look at how many jobs Horses had in the year 1900. They did everything from move people to haul stuff to ride into war. All those jobs sucked for horses.

        Imagine the horses looked at cars and thought, "well, those cars might replace some of our jobs, but as we move into the city, there will be lots of people, so there will be plenty of new things for us to do.

        As a human looking back past the year 2000, you know this is absurd, there are few jobs today that a horse can do that pays for its care and feed.

        Horses didn't become unemployed because they became fat and lazy, they became unemployable. The horse population peaked around 100 years ago and it has been nothing but downhill since.

        It won't happen next year, or even 5 years from now... but at some point... all those drivers, from taxis to trucks, will become unemployable through no fault of their own. They simply will not be able to compete with the cost of a robot.

          Oh, I agree with you and that sentiment completely.

          To be specific, take a look at Manna, by Marshall Brain [marshallbrain.com]. It's an easy read, and it shows in frighteningly clear steps the two different ways the economy can go.

          I'm all for automation, and I've worked on automation projects before. By and large, automation takes away those jobs that humans don't really want to do. Boring, repetitive, dehumanizing things like crop harvesting or long-haul driving.

          • While I recognize that automated production is the way of the future, I'm not quite sure how to get there. If there were some clear path, I'd be advocating it.

            The best I can come up with at the moment is to point out how we're going to be in tough straits when 3 million people find themselves without a job in the next 5 years (and 2 1/2 million after that when short-haul driving is mostly automated, automated drone delivery of packages and mail and such.)

            I can picture a future 50 years from now, but like you, getting there appears to be painful.

            What do you do with all those people when they no longer are employable? Find them something else to do? Perhaps... but if we make everything with robots, at some point, humans aren't... really needed...

            Do you have any ideas on how we can be part of that transition?

            No, because so many people are stuck in old mindsets and don't want to change. People are quite stubborn, myself included sometimes. :)

            Oh no, very much no. It dropped to another new low in the latest recession. A whole lot of horses went to the knackers in that one. Local trailer store on the 101 put up a sign FREE HORSE WITH TRAILER.

              Dude US horse population bottomed in the 1950s somewhere below 2 million. By 2003 it was back to 6.9 million and it is presently estimated at 9.2 million by the American Horse Council.

              Trust me, I've done extensive research on this issue.

              • Are those wild horses or horses in captivity?

                I was referring only to those who are housed and fed by us, not those in the wild.

                • by Alomex ( 148003 )

                  Those figures are combined, but the number of wild horses is very small: less than 1% of the total above.

                    • by Alomex ( 148003 )

                      Wild horses for the most part live in Federal land. Statistics about those are published by the US government.

                      Indeed finding the data isn't easy. It took me a long time to find them back when I was doing research on this.

                      "How many horses in 1915 were being used in commercial activities and how many are being used for those same activities in 2015"

                      Even ranchers no longer use horses as much, I know ranchers in Texas who have switched to helicopters, they are faster and better than horses.

          Can they do it? Or am I still a drooling, panting idiot?

          • If this Daimler truck gets accepted on the roads it will then allow drivers to sleep at the wheel on highways. (which they do already, but that doesn't always end well). Or eat, read, etc.
            That's a good thing, but there's no way in hell you're getting rid of the driver in that scheme.

            • Of course that's just one step away from moving all the drivers to a central facility and remote controlling the trucks as necessary. Then you get to the point where each operator can run multiple trucks. Even if you never remove humans from the equation entirely if you change the truck to driver ratio from 1:1 to 30:1 you're going to have a huge number of people out of work.

                I can see a system where a couple of people, working together, could move around a hundred trailers across the country along a fixed route -- possibly along a pair of rails running parallel to one another. Something like that would put an awful lot of truckers out of work.

                • Yes, trains are nice where there are tracks and you're shipping the right kind of load. Despite trains many advantages trucks are often better for a variety of reasons, that has little to do with whether they're automated or not.

          Ok, you're ranting, but I actually understand your points...

          I don't think this will happen in 5 years, but I do think I'll see it in the next 25 years.

          If Google isn't taking 100% liability for their self driving cars, then these will never be viable in industry. Because you end up needing a driver as a backup -- but the driver will lose concentration and be a terrible backup. So any time the computer fails, the human will be too damned late to help. Not unless your software can predict it's failure minutes out instead of seconds.

          Google isn't the only company working on this, everyone from Ford to BMW is working on it.

          Computers aren't perfect, but they don't have to be perfect, they only have to be better than us.

      Now it might not be ready for what Amazon needs, but given the size of Amazon's workforce, their budget, and the possible savings from having a million such robots and not needing to "surge hire" for the holidays, clearly this is a goal that Amazon will continue to peruse.

        From your own link: $25,000 buys a basic robot with arms that does nothing useful, with a 1-year warranty on the hardware and 1 year of software updates.

        If you want it to grip something with those arms, that's another $1,750 per gripper (ie: per arm).

        If you want it to lift something with vacuum, that's $1,750-$2,700.

        If you want a set of wheels so you can move the thing around without a forklift, that's another $3,000.

        If you want software updates after a year, or more than a year worth of warranty service,

        • All true... And the first Mac in 1984 had a 7 MHz CPU and 128K of memory and a 400k floppy drive and came with a little 9" monochrome screen... all for $2,500!

          So those darn computers will never be useful. :)

            There was no other implication.

            • Fair enough.

              Let me toss another thought out... If you wanted 1,000 Baxters, do you think the price would remain the same?

              How about 100,000?

              That is one interesting thing about robots, at some point scale of manufacturing gets interesting, and once you've taught one of them something, they all know it.

              Even if the cost of all the add-ons and the robot is equal to the cost of an employee's annual wage, the robot works 24/7, the human does not, and the robot likely will last for many years.

                I'm all for automation.

                And I hope that if someone orders 1,000 Baxters, the price will adjust. (How muich? Who knows. Instead of $30k is it $25k? Is it $20k with 6 years of software updates, but zero hardware warranty? Mass quantities of anything are a thing that is seldom quantified on a web site.)

            Ask most females who they'd rather date: a warehouse picker, or a guy who sits around all day watching TV and collecting welfare?

              ...and they'll answer "the good looking one with the motorcycle".

        • So people should stop buying "stuff"? That will solve Amazon's warehouse labour problem. No more Amazon.

        • People only get satisfaction out of working for other people because they have been raised with a slave mentality and they forgot how to be themselves. They were bred to be cogs in the machine, bricks in the wall, and most people participate faithfully.

          Let people be people.

          We need better birth control :p

          • Not everybody should be themselves. A lot of people suck.

            That might be true, but the culture is what the culture is. Republicans commonly denigrate "free-loaders" and that's not going to change any time soon. Our identity is tied to our work, for good or bad.

    What I'm getting from this is, these robots suck. But they might replace some jobs due to a vacuum in the market for free workers.

  • This thing about having a robot detect stuff and select it sounds error prone. If I was the one creating this gigantic vending machine, I would think it would be easier to put things in predictable places. (like they do in a vending machine) This way, you know that the thing in address x is a y. A step better would be to the have the robots put things away in their correct places. Some sort of easy to grab container could be used for each object to reduce the complexity of the hardware picking up the merc

    • Exactly. A warehouse is nothing but a physical database.
      Goods are placed and retrieved at specific locations. If something's wrong a manual check and correction can be done, or maybe have one or two robots with good visual recognition randomly check locations and the contents for correctness.

      There you go - YouTube video of the iHerb "vending machine" [youtube.com]... pretty cool to it work - skip to around 1:18 to see the "vending machine" ... watch the whole thing to see how optimising the packing, before it gets stocked helps speed things up.

      Modularity.
      This is their current situation. Stuff comes in different sized packages, and placement is not perfect.
      Of course they could get improvements, even for human workers, if stuff came pre-checked, correctly classified and stuff. The thing is that's not their current status. The idea is to get rid of the picking human, without changing anything other than the human.
      Self driving cars would be easy with the strategy you propose, just build intelligent roads, wired roads with wireless navigation, no peop

  • I think the future of massive warehouses will involve RFIDs and standardised packaging. Products are packed far too randomly ... if standard packages were deployed, robots dexterity could perhaps be reduced?

  • From the summary and TFA:

    Chances seem good that Amazon will ask future teams to build machines that are even smarter and faster.

    The chances that Amazon will want future warehouse robots to be "even smarter and faster" are "good"?? Okay, I suppose the probability that they will want future robots to be dumber and slower is technically non-zero, but I'd at least revise "good" to "almost certain".

  • HAL still won't open that damned pod bay door.

  • I saw an automated warehouse at Kodak in Rochester, New York, in 1975. What am I missing? Why is it so difficult now when it was done in 1975? The computers remembered where stuff was stored and the pickers just went to the spot and got the item. Some details omitted here, of course, but that was a long time ago when the relevant technology was relatively primitive.

  • If I catch a robot handling my book like shown in the video I'm gonna wreck it and sell it for scrap.
    Or mod it into my personal coffee machine.

  • Their winning design combined a WAM arm (complete with a suction cup for lifting objects) and an XR4000 mobile base into a single unit

    The chief designer, a Dr Davros of Skaro, CA, welcomed his 'supreme victory' in the competition, but questioned Amazon's decision not to proceed with the immediate replacement of their entire human workforce with his creation: 'Do you believe that I would let a lifetime's work be ended by the will of spineless fools like you? You have won nothing. I allowed this charade to be played out for one reason only. To find those men who were truly loyal to me and to discover those who would betray me! WE... I WILL

  • As corporate-profits motivate more and more replacement of humans with automation, societal attitudes about employment are still moored in the Industrial Revolution age.

    If you don't have a job, you're a bum - doubly so if you are a man, just to pile on the Puritanistic guilt.

    I can't recall where I saw it - perhaps the Daily Dot or the Daily Beast, but it was a map of the most common job in every state of 2015 America. The most common in total for the country? Truck Driver.

    In about ten years, the only jo
    • In about ten years, the only jobs left will be in the private riot police squads, trying to hold back the tsunami of the unemployed assaulting the One-Percenter citadels to extract their revenge.

      Your timeline is a tad extreme, though in general I think we will see rising structural unemployment and eventually it's going to be a serious social problem.

This is now. Later is later.
