How dairy robots are changing work for cows and farmers(spectrum.ieee.org)

These videos of robotic cow milking machines, feed mixers and distributers and pushers, and manure roombas are amazing!

Cows like to push and play with their food to get to the yummy grain bits, so the feed robot pushes the food back so they can eat it all.

And the Poopoombas had to learn to be more aggressive about pushing cows out of the way and not stopping every time they bumped or got kicked, because otherwise the cows would assign them the lowest status in the pecking order, and they could only cower in the corner.

Here are the videos from the article and some more:

Now dairy farms can use two different kinds of AI together! ;) They could develop an insemination module to go with their calving module.

I wonder if you can rent swarms of these and dispatch them to anywhere you need them:

Or if you can use them in reverse, loading them up them dumping shit wherever you wanted to, like a giant Logo Turdle, in the name of art and science.

These machines have been around for a while. There are at least nine companies selling them.[1] This started in Australia and New Zealand, which don't have much cheap labor.

There's a competing approach - robotic rotary milking.[2] Rotary milkers (giant turntables with cows on them) have been around for decades, and are becoming more automated, down from four people to one.

All this stuff works fine. So there's a huge milk glut.

Well, you would expect a lowering of production costs to translate into a lowering of consumer prices in a competitive market?

mschuster91 4/16/2025||
The problem is manifold in its aspects which means there isn't such a clear cause-effect link.

1. countries really don't like being dependent on other countries for feeding their population - the current Russian invasion in Ukraine and the issues surrounding their grain exports have shown how bad such dependencies can get in the worst case.

2. basic agricultural staples - potatoes, grain, rice, but also eggs and milk in powder form - are a global market these days, which means there's a ruthless competition in place, made worse by at least the US and EU doling out insane amounts of subsidies for their farmers.

3. in some markets like China, scandals around food are the norm, which in the case of milk powder led to second order effects like Chinese tourists and expats in Western countries buying up milk powder at scale and shipping it back to their relatives in China - which led to a massive increase in price in affected Western markets, and to the political question if governments are effectively subsidizing China's issues at the cost of citizens.

4. Western masses are getting ever more poor which puts an insane amount of political relevancy to the price of food (see e.g. the current egg issues in the US). At the same time, both distribution, refinement and production of milk (and other agricultural commodities) has seen a massive consolidation wave in the last decades, giving these mega-corporations a massive amount of leverage over everyone else.

5. To protect their farmers, some countries have introduced price regulations (minimal prices) or tariffs, in addition to the subsidies.

Worse for some suppliers, but better for customers. It's very nice of US and EU tax payers to give the rest of the world cheaper food. Just like it's nice of Chinese tax payers to give the rest of the world cheaper solar cells.

Citation needed. Normal statistics say that 'western masses' are getting ever richer.

mschuster91 4/16/2025||
> Worse for some suppliers, but better for customers.

The problem is, it leads to cost-cutting and unsafe practices. The fact that American eggs and poultry meat need to be washed because it would otherwise be unsafe to eat from the horrible conditions the poultry is exposed to is telling enough.

> Citation needed. Normal statistics say that 'western masses' are getting ever richer.

Total wealth may grow but the distribution is ever more in favor of the ultra-rich [1]. Half of Americans report having to live paycheck to paycheck, mostly due to housing and fixed costs of living growing way faster than wages [2].

They only need to be washed, because that's what the regulations say. If the regulations say that they need to be save without washing, that's what farmers would deliver. Farmers in the EU aren't any less greedy.

People all across the wealth spectrum are getting richer.

But in any case, coming back to the 'milk glut': cheap milk makes more of a difference for poor people than for rich people.

It's cool that this allows the cows to be milked whenever they feel like it. I'd imagine the autonomy actually does improve the cow's quality of life. Also neat that they learned to game the feeding robot. It reminds me of the image recognition experiments they do with birds.
DonHopkins 4/15/2025||
And how they had to inhibit greedy cows with the munchies from volunteering to be milked too often, just to get treats!

There are certain things you just can't predict, and have to learn in the field...

Aardwolf 4/16/2025|||
Do you think cows care about human interaction, or are indifferent whether it's a living creature or a robot?
eitland 4/16/2025|||
Varies from cow to cow I guess.

One particular cow ("Evjelin" IIRC) would try to avoid her own calves because (it seemed) she much preferred the machine it seemed.

The final year we found her calf with a broken neck in a flat area of the pasture. (Yes, they were always allowed to stay outdoors around when they calved and usually they spent a few days outside together. Mostly this was great I think and except this incident I only remember one other were it was a problem: one calf had got under the fence and into the bog and the cow had followed it into the bog and it was a real mess and I was a really proud teenager when I was able to get out the calf. Both of them needed help to get out but both survived and recovered nicely IIRC.)

Cows are herd animals and like to be in herds of 100-200. Most don't care about humans, though some enjoy pets from humans.

The fact that cows can self-schedule is kind of amazing
ahartman00 4/16/2025||
They aren't really scheduling though. They can feel when their udders get full. It actually can be painful if you don't milk them on time. Its comparable to eating or drinking, they go eat when they feel hunger. It is pretty cool that they learn to associate the machine though, its not like it smells the way food does, or like there is any instinct involved.
hommelix 4/16/2025||
I don't know the current state of readiness for the milking robots, but 10 years ago it was a nightmare. When a cow got blocked in the robot, the farmer get notify and stops what he is doing to check the cow and the robot. With the free access to the milking robot 24/7 it means that as a farmer you can get your phone ringing to free a cow stuck in the robot at 3 am, or when you are 20 miles away in a field. This level of stress caused many farmers to sell their milking robot and come back to two milking sessions a day, typically 6 am and 6 pm.

I imagine it's gotten better with newer generations, but your point's a good reminder that "automation" doesn’t always mean "less work"
decimalenough 4/16/2025||
China famously now has "dark factories" where everything is automated, so lighting is not needed.

Guess this means we're about to have "dark dairies" where cows can be kept chained up in perpetual darkness, with robots doing the absolute minimum required to keep them alive, pregnant and producing milk.

I know this is not a particularly pleasant thought, but I'd like to hear counterarguments about why this wouldn't happen, since to me it seems market pressures will otherwise drive dairies in this direction.

(For what it's worth, I'm not a vegan, but a visit to a regular human-run dairy sufficiently confident in its practices to conduct tours for the public was almost enough to put me off dairy products for good.)

hibikir 4/16/2025||
For something like milk, which is produced by mammals to feed young ones, there's all kinds of biological connections between a relaxed, healthy, content animal and milk production. We are humans, it's not much different for us. So as far as milk production goes, the wellbeing of the cow lines up relatively well with productivity. A stressed, unhealthy animal isn't going produce all that well. Often the limitation isn't the disinterest in the wellbeing of the animal, but the capital and labor required to improve conditions.

Quality tech can actually improve animal welfare, as shifting costs from labor into capital makes quality of care improve.

Now, this doesn't always line up well in all kinds of animal husbandry, but you went and looked at one case where it does. The dark dairy you imagine would most likely lose money.

aaronbaugher 4/16/2025|||
Farm kid here. While it's true that farmers have an incentive to keep their animals in good condition, that's not the only incentive toward profit, and the bottom line often results in a pretty stressed, unhealthy animal that's in good enough condition to keep producing. If you can save $X by providing a minimum feed ration and leaving the cows in the care of the cheapest, least-caring employees you can find, and that reduces your milk check by less than $X, that's what's going to happen in a lot of cases, especially the larger operations.

(Not unlike human employers who have an incentive to treat their employees well but often don't.)

Farm organizations like to say farmers have every reason to keep their livestock in the best condition, implying that they're frolicking on pasture in peak health, but that's not really true. A lot of times it means miserable condition on concrete or a freezing feedlot. Livestock animals, like humans, are resilient and can keep producing through some pretty terrible treatment. The only ways to combat that seem to be A) customers who actively seek out farms that practice good animal welfare practices, or B) reasonable animal welfare laws.

"A somatic cell count (SCC) is a cell count of somatic cells in a fluid specimen, usually milk. In dairying, the SCC is an indicator of the quality of milk—specifically, its low likeliness to contain harmful bacteria, and thus its high food safety."

"Lights out manufacturing" has been a thing around the world for literally decades. This is not new. The main "problem" is feeding the machines enough raw material and removing finished parts so they can keep running without human intervention. Not surprisingly, there are now robots for that.

These robots don't look conducive to automating the labor specific to factory farming. Overlap with manure cleanup at best, but do factory farms have spacious enough layouts to be compatible with those?

More generally, the egg market in the US has gone from 4% cage-free in 2010 to 39.7% cage-free in 2024. Cows don't have a "non-factory" label but I don't see why one wouldn't be as successful. You also supposedly get more milk per cow the nice way.

The far future will have ever more cows per capita given human fertility trends, so I don't see the preference for quality over quantity regressing, or any sudden need to produce more milk than ever.

aaronbaugher 4/16/2025|||
Where I live, there are still some small, family-run dairies, and they all have customers who come to them looking for local, pasture-raised, raw milk. People will even break the law to get it, so there's definitely a market, but current regulations make it difficult to serve it.

Small, direct-to-customer farms are the ones most likely to lean into customer-pleasing animal welfare practices. But to profitably sell direct to customers within the law in most US jurisdictions, a dairy pretty much has to put in its own pasteurization setup, a major investment. That's kept dairy from developing the equivalent of cage-free eggs.

> the egg market in the US has gone from 4% cage-free in 2010 to 39.7% cage-free in 2024.

What does that really mean, though? A farmer down the road produces "free-range" chickens. While it is true that the operation is technically setup for it, which is what is required to meet certification, never in my life have I seen the barn doors open.

You don't ACTUALLY force "dark factory" to be completely pitch dark. That phrase just means they would not be required to follow legal light level requirements(there are such things) and technically considered a "dark" place.

No one buys pigs and cows grown chained inside abandoned mineshafts. It doesn't save any costs and just doesn't make sense.

Ok that's a stat I didn't expect. 68kg! That's ~150lbs! Holy crap.

pests 4/16/2025||
I sometimes watch a concrete YouTuber. He recently did a manure pump pit. I honestly didn't realize the scale of manure management. A massive holding tank for all the produced waste. All the areas with cows will have ways of pushing and moving that manure out into trenches and eventually into a massive pit. The pump pit was so they could get to the lowest point and pump the product into its next stage of processing / use. Its a valuable byproduct so worth dealing with but just never thought about what goes in must come out, and cows eat a lot.

Does that matter? I'm not trying to be sarcastic or glib, does it help in any way that it's half water?

It's probably not an accurate comparison, but I don't find any consolation in the fact that a lot of the bulk/weight of cleaning my cat's litter box is water. I don't know if it meaningfully changes anything about the task for a cow though.

toddmatthews 4/15/2025|||
its actually 70-90% water. it matters because water is very heavy, and whats left over will be dramatically less after it dries out.

Yeah cow manure is VERY wet.

Compare to horse manure which is relatively dry, easy to shovel.

delecti 4/16/2025|||
The context was shoveling a barn, and you can't leave it until it dries out, can you? I don't know how often you have to clean a barn, or how long it takes for the manure to dry, but my naive assumption would be that it takes too long to dry for how often you need to shovel.

Super interesting read! But also feels a bit like a paid advertisement. You'd think that an article about robot farms would mention more than one brand of robot? Guessing this is the submarine at work:

https://www.paulgraham.com/submarine.html

It makes me wonder what the author isn't mentioning. Do they have bugs that take the whole farm down? If the internet goes out, do the machines start acting weird? I'm not a luddite, I love the idea of a robot farm, I just want a complete story.

BenjiWiebe 4/16/2025||
We have one DeLaval robot. It works without internet, except our phones no longer receive the "stop alarms" (something broke, need human) if the robot is offline.

There so far haven't been serious software bugs, only minor/annoying ones. Hardware, on the other hand... Things break, and then it's number one priority to fix it, even if it's 2am Sunday morning. Our poor dealer has received a number of calls in the middle of the night and/or on a weekend.

We're fairly handy though, so a decent number of problems are things we can either fix or invent a workaround for.

Most recent example: the hydraulic pump motor bearing spun in the aluminum housing, and developed so much play that the rotor actually jammed against the stator/armature. Turns out JB Kwik (faster JB Weld, epoxy) actually works to hold a bearing in place. The rotor shaft naturally tended to stay in the center (the other bearing was fine), so the epoxy cured with the bearing in the right spot, and then we were good to go.

The replacement motor has arrived but has not yet been installed.

BotJunkie 4/16/2025|||
I'm the author of this piece, and I'm happy to tell you where it came from.

I was at a robotics conference in Boulder last spring, where some folks from Lely presented a paper on their robotic code of conduct. I hadn't heard of robots for cows before, and thought it was fascinating. I happened to be in Rotterdam last fall for another conference, which was close enough to the Lely headquarters for a visit.

Lely is somewhat unique in that they're a robotics company rather than an agricultural machinery company that also makes some robots. There are a few other companies that make robotic systems like these, but Lely is the largest by a significant margin. Farms will often choose what brand of robot to buy based on what service center is closest to them, in case something goes wrong. I believe that Lely promises that they'll have someone on-site to fix (or, start fixing) a broken robot within about 2 hours.

The majority of farms who switch to these robots keep them- an expert that we talked to said that it's not common to go back, and only a small percentage do.

9rx 4/16/2025||
> Lely is somewhat unique in that they're a robotics company rather than an agricultural machinery company that also makes some robots.

What equipment from the major agricultural manufacturers would you consider to be not robots these days? Even a simple tool like a field cultivator now employs robotics for things like keeping it at a precise depth, never mind the extensive robotics involved in more complex equipment.

There are some smaller companies still producing agricultural equipment that is not recognizable as a robot, but I'd consider that to be the exception rather than the norm.

BotJunkie 4/16/2025||
Personally (and to some extent, professionally) I make a distinction between robotics and automation. In robotics, I look for a distinct, physically embodied system that can make decisions based on its environment and alter that environment by changing its behavior. Automation is much more limited and requires a much more structured environment. But it's all a matter of perspective.
9rx 4/17/2025||
Fair to say that it is a matter of perspective, but by your perspective the cultivator is a robot, right? A field is far less structured than a barn, and the tool makes decisions about how to alter its behaviour and environment in a pretty grand and visible fashion. Lely products are much closer to being automation in comparison.

Perhaps a more pedantic take is that the cultivator is simply attachment for the actual robot, which is the tractor. A cultivator on its own is useless. In that vein, there is seemingly a difference. Each product Lely sells is the full solution. Whereas John Deere gives you a menu and you have to select which "toppings" you want on your robot.

But then that gives nod to Lely products being closer to automation than robotics again. Beyond choosing a product at a high level, you don't have to get into the nitty gritty details because they will always operate in a comparatively strict and consistent environment.

aucisson_masque 4/16/2025||
Indeed, it reads as an advertisement.

No downsight at all even though it has big flaws. The constant alarm, sometimes when sleeping because something got stuck, the maintenance price, cost of certified technicians.

Nothing about the price and ROI.

Nothing about the farmers who bought them and their experience years later, a considerable part would not buy it again and instead just come back to build a parlor and milking 2 times a day.

As you pointed, nothing about other brand.

All sunshine and rainbows..

If it's journalism, it's bad one.

AngryData 4/16/2025|
This is neat but definitely seems like something for tiny little dairy farms still. Like they quote 30-40 seconds in the article to hook a cow up to a milker with a robot, but a human can do it in 3-4 seconds and with a rotary milker they can milk near 5,000 cows 3x a day like that . That said it does usually take 3 or 4 people to run a rotary milker, 1 for udder cleaning, 1-2 for attaching milkers, and 1 for post-milk sanitizing. But of course the people working there are generally the most desperate of society because they get shit and pissed on all day and stink even after bathing, so only costs around $10 an hour.

Not saying im not hoping this all improves or that it is good as-is, but the reality is these robots are competing with bottom of the barrel wages from tweakers working at a breakneck pace with live and moving and variable animals so it isn't easy and still has a ways to go before most peoples milk production can be automated.

Maybe things are very different in the US but in the systems I'm familiar with (UK, Ireland, New Zealand) rotary is usually done by 1 or 2 people, the work requires care and knowledge so they are generally paid well above minimum wage and are experienced agricultural workers, they generally dont get covered in piss and shit and they don't stink

Yeah, that's overstating it. I help milk about 60 cows every weekend, and while there's certainly manure involved, and sometimes you get some on you, I've never been "shit and pissed on all day." I wouldn't go straight from the milking parlor to a date without a shower and a change of clothes, but that's true of any physical labor.

It is a lot easier to stay clean when you are doing 60 cows rather than 4,500 cows on a rotary milker set 4 feet higher than you are.

Yeah I dunno, having seen rotaries in action and knowing a little about the hygiene and efficiency requirements of modern dairy farming, there are several things in your description that don't add up for me

I've never milked in a rotary parlor, but I have worked in a farm with a regular parlor, as well as the traditional stall barn. I was way cleaner milking ~200 cows in a parlor vs ~40-70 in a stall barn. Obviously, clean is a relative term here :)

Both Lely and DeLaval seems to have at least some customers with thousands of cows.
