Tux Can Even Milk Cows! 313

GuitarNeophyte writes "If you're a cow, you want to get milked when you want to get milked. And if you were a dairy farmer, you want to make your cow happy. So what do you do? Set up a machine that gives the cow control of its milking schedule. Oh yeah, of course, it runs on Linux. It identifies the cow, then finds the udders, milks the cow, cleans it's undercarriage, and lets it go."

    Saw it yesterday on a link from linuxdevices (rad site, check it out).

    Showed it to my friend who grew up on a cow farm, he was blown away, the video will get slashdotted but I recommend bookmarking and returning some time after to grab the high res video (~ 52 meg) as the accuracy of the teat suckion caps is pretty amazing, laser guided milky goodness.

    Basically, cow gets duped into walking into a little pen with tasty food, the machine cleans it's teats, attaches cups with laser guided arm in an impressive display of dexterity, cow gets milked, computer monitors and gets all the stats, suckion caps come off, door on other side of pen opens, cow goes out.

    Nothing alpha or beta about it, you could see it going into production straight away. I suspect if the cow started fucking around maybe the system would have trouble, but the back of the pen closes in a little after the cow goes in, so it can't run around. And it's pretty busy chomping on the food they give it to notice.

    The biggest decider would be maintenance/support contracts and inital cost I suppose. (anyone track down the cost?)

    Other than that, a good example of robotic automation.

    • I'll be passing it on to my co-worker who has a small dairy farm with her husband. They keep trying to go on vacation, but can't find anyone they really trust with the cows. Getting the cows to milk themselves would be pretty amazing. There seem to be some scheduling issues that would cause problems, though. The collection and storage system would have to be running all day instead of just during two times a day.

      But, joking aside, from what I heard, the device has several reservoirs, and is capable of doing a quick analysis of the milk (presumably, in order to put milk of slightly ill cows in a different reservoir, avoiding to spoil the milk of healthy cows).

      So then they could just file the "salty milk" in a reservoir of its own (which might even be useful to the farmer: just sell it to a neighboring farmer who d

    If you're going to use only 1% of a 40GB harddrive, why not just use a tiny bit of onboard memory and remove the entire harddrive from the equation?
    • memory goes away when the power goes out, and apparently flash memory is too expensive or slow.

Plus I sincerely doubt they're even using 1% of a 40GB drive (400 MB??) unless they did Red Hat's "minimal" installation which is around that size.

    This is just slashdot trying to milk Linux's popularity.

    I wonder how many anonymous COWards we'll have posting for this one.

    Does the distro have cowsay preinstalled?

    Lots of mootivated developers contributed to the project.

    Actually, whilst at work, I happened to see this (not sure which channel) and was oddly intrigued by the machine. Apparently, the cows used to be milked twice a day, but when they milk themselves, it can be 6 times a day! The tech used was pretty complicated, as well. Lasers guide the "milkers" onto the nipples and it rarely misses it's target. Once connected, it auto-milks, and once done, it immediately unsucks the milkers and releases the cow. Repeat as necessary.

    This machine also provides some solace for the bovines, because they can simply walk into the "robot," and they are alone and fed for the length of their milking. Simple.

    My question after seeing the show: If the cows are milked more often, did the milk production increase? I assume it must by some level.

  • "According to Hansson, early versions of VMS were based on an M68K CPU board, running OS9. "Later on we changed to an industrial standard PC-board," he says. "Along with that we also changed operating system. We went for Linux since some of us had worked with it and we believed that moving from OS9 to Linux would be rather easy."

    Mac OS 9 requires a PPC processor to operate, 8.1 was the last M68K compatible version. With that in mind I think they are referring to OS/9 [rtsi.com].
    • > With that in mind I think they are referring to OS/9.

      It was immediately obvious to me that they were talking about OS/9. They clearly weren't going to use an Apple operating system that has never been licensed for industrial use. Do you think anyone might have actually thought otherwise?
      • Yes, of course people might of thought otherwise, hence why I bothered writing the comment.

        OS/9 is extremely obscure, even amongst the slashdot crowd and the name similarity to Mac OS 9, recent pro-Apple trend and M68K-Apple association could account for quite a bit of confusion, don't you think? Meanwhile, is linux licensed for industrial use? Does it even matter? I've seen old ATM's running DOS, so what the fuck is your point?

    It identifies the cow, then finds the udders, milks the cow, cleans it's undercarriage, and lets it go.

    Perhaps we should wait for the version with the bug fix, the one that identifies the cow, then finds the udders, cleans it's undercarriage, milks the cow, and lets it go. The cleaning is for the sake of the quality of the milk, not for the cow! Feel free to add a step that does a second pass after the milking, but it needs to be done before.

    • From TFM
      "A multipurpose robotic arm then extends underneath the cow and, guided by laser and photo sensors, cleans and dries each teat before attaching vacuum milking cups."
    • It's true that you need to clean before milking. But maybe it is a good idea too, to clean the teats after milking. How healthy would it be for a cow to walk around with udders/teats with (dried-up) milk on them?

    There's one of these just down the road from my place. A guest lecturer spoke about this to my class. The article didn't go into specifics about how the cow "decides" when to get milked (or at least I didn't see that in my hasty skimming of the article), but the one here works like so: The center of the paddock has the only water trough fenced off, with three gates to it. The cow can only enter through one specific gate. When it does, a scanner reads a tag on the cow's ear, and the computer checks if it's time for the specific cow to be milked again. If so, the exit gate that leads to the milking machine is opened. If not, then the exit gate that leads to the paddock is opened. One of the implications of this is that better quality milk is got from the cows. (This is in Waikato, NZ - if anyone was wondering).

    I worked with a "Down Maine" dairyman for some years. We were pretty careful around the cows. There was a whole lot of concern about infection, mastitis, quantity put out by each cow, when we needed to fertilize them again (you don't get milk from a cow that hasn't had a calf and you have to get them pregnant every so often to keep production up) and so on. We did our best to keep the cows happy and keep production up.

    We went through a lot of a sticky substance called "Bag Balm." [bagbalm.com] We used it to decrease the amount of irritation cows felt when being milked by a milking machine that used air pressure. Either this device uses a different pressure or I'll bet a lot of their cows have to be taken out of the system periodically.

    I really like how well the system monitors and logs in production for each cow. The movie file indicates that it keeps track of "each quarter." That is a kind of granularity that we could never achieve with our milking system, where we would weigh the total output of each cow and keep track of that. We also kept an eye on cream and butterfat content.

    I do wonder what happens when (and if) more than one cow "wants" to be milked at the same time. Does a brawl ensue?

    For those who don't know it, cows tend to be milked twice daily at 12-hour intervals in order to ensure the highest possible output. It's kind of difficult to switch them to daylight savings time and many dairymen just don't try. Cows who are not milked experience considerable pain if they are not and may develop mastitis. The same goes for all female mammals who are producing milk. If a cow's output can be increased by varying the times of milking just a bit, dairymen could pay for the device in a few years.
