I always wonder why those robots have to be humanoid.

I swear I don't need a humanoid robot, give me a proper autonomous robot that cleans your house and I'm more than happy. Could be 40 cm tall, and look like a box, I don't care.

    1. The world is designed for humans. If you need to reach the places humans reach then you need to be the same size as a human.

    2. Nature has tested many different form factors and the human form dominated the others.

    • epolanski 3 days ago

      But this is all based on the idea we need generic robots when we really need specialized ones.

      It's like skipping making kitchen blenders and vacuum cleaners and instead building a robot that will be mixing stuff manually or using a broom.

      Manufacturing, where 90% of the process is generally automated has countless specialized ones. It would not make sense to put generic ones there, because humans really are doing very specific work in manufacturing.

      • sejje 3 days ago

        I agree there's a great market for specialized ones. I own some of those, like a vacuum bot.

        But the generic robot is the endgame. I think Musk tries to achieve the endgame, probably too soon. FSD, interplanetary travel, etc

      Ask a plumber what he thinks about reaching places human reach. Nature tested what exactly? Birds and spiders are sub optimal?

      • zarzavat 3 days ago

        Birds and spiders are much smaller than humans, see point 1. It's unlikely that a bird, spider, or even a rat will be able to cook dinner for you.

        Birds are much better at being dinner. The most "successful" bird by a very wide margin is the broiler chicken.

        Of the individual animals that are the same scale as humans, the vast majority exist either to be eaten by humans, serve humans, or be cute for humans.

        The most successful wild animals of a similar size to humans have 10s of millions of individuals, not billions. Seals for example thrive by existing in places that humans are not suited for.

      1 is the real reason. 2 is really down to things like a big brain and opposable thumbs. Our trunk/legs are evolved for persistence hunting and long distance walking - activities that drive approximately 0% of the economy at this point. If robots didn't have to navigate an environment built for bipeds, other configurations would be far more reliable/efficient.

      For instance: a quadruped base can be statically stable in case of power loss - a biped really can't.

    “I always wonder why those robots have to be humanoid.“

    You are correct to wonder this and almost every use case for a robot will be optimized to a non-human form factor.

    Certainly there are tasks - like BJJ training partner - that require a human form factor. Almost everything else, including general, purpose, helper, robot, will be cheaper and more extensible in a non-human form factor.

    One of your children remarked that nature has experimented with form factors and humans have won… To which I would point out that the upright, bipedal, form factor arose from the limits of oxygen processing, and heat dissipation… Neither limitation will be encountered in the same way with a robot…

    … or perhaps I would point out that nature has, indeed, experimented with form factors and ants won - by a very large margin.

    instead, sub 12cm disc shaped ones are rather well understood and perform well. They suck opening doors though - but the 40cm one would have a similar issue.

    Besides that: I, personally, am totally fine with the current state of the technology.

I think the technology is just not there to make the business case for humanoid robots. It’s like the VR. Everyone would like to use VR but the tech is just not good enough. Same with FSD. The robots may be 10-20 years away from actual being good enough. If Elon can trick people for 20 years like he did with FSD then he may have a business case for humanoid robots

array_key_first 3 days ago

Yes, there's no business case for humanoid robots.

There's a business case for robots that are specialized in specific repetitive actions, and we already see this in manufacturing. But general purpose humanoid robots make no sense.

They're incredibly expensive and, from what we've seen, worse across the board compared to humans. It's cheaper to just hire humans.

The human form is actually pretty shit at most things. But, it can do everything. There's just little purpose for that in a business case. You know what you're doing, so you just need robots to do that, not to try to be humans.

Like, okay, you can get a humanoid robot to be a burger flipper. But that makes no sense. You can, instead, have an automated burger cooking machine. Which do exist! I worked in a restaurant with one 10 years ago.

Robots yes. Humanoid ones? Why? So people can be amazed? Purpose built robots are the future. The human form is sub optimal for most enterprise use cases.

  • johnfn 4 days ago

    I don't understand why my question was so controversial. Oftentimes on this website I feel like everyone is tapped into some polarizing news source that I am not, and so when I ask some (to my mind) benign question it's actually a secret tripwire that everyone is super polarized on and so rather than engaging in my question they all just tell me I am a moron. But I am seriously just asking a question here.

    My layman's opinion is that I would happily pay a lot of money to have a robot help me around the house: fold my clothes, do the dishes, whatever dumb menial labor. That seems like a business case to me, unless someone is going to tell me I'm the only one in the world who could want that (but I doubt it).

    OP said:

    > Humanoid robots? Ain’t nobody made the business case for that. It is pure vibes.

    I can't make sense of this. Are you really telling me you wouldn't pay any amount of money to do menial housework? If not, why not?

    • f30e3dfed1c9 3 days ago

      "My layman's opinion is that I would happily pay a lot of money to have a robot help me around the house: fold my clothes, do the dishes, whatever dumb menial labor. That seems like a business case to me, unless someone is going to tell me I'm the only one in the world who could want that (but I doubt it)."

      How much is "a lot of money"? Not picking on you, happy to let you want what you want, but people often seem to mention laundry, which mystifies me.

      I am an adult male in the US. I do not need to dress for work in any way I would not dress anyway. Basically, I do two loads of laundry a week, one for clothes, one for towels and bedding.

      This requires about one hour of actual work per week. More if we counted "waiting for the washing machine" and "waiting for the dryer" as work, but I don't.

      How much would I pay to remove this hour a week of (really easy) work from my life? Almost nothing. I would not, for example, pay someone $50 to come to my house and do it for me. It's not a problem and doesn't need a solution.

      So how much would you really pay for a robot that did your laundry, washed your dishes, and did other "dumb menial labor"?

      • edmundsauto 3 days ago

        Reliably? $25k. Having kids means I have less time to do more chores, if I could convert those chore-hours to family quality time, it would be invaluable.

        • f30e3dfed1c9 3 days ago

          I recognize that having kids too young to do their own laundry could change the calculus.

          Maybe there will be a $25K robot that can do laundry before your kids grow up enough, but can't recommend holding your breath.

      - last 10 years at least

      I will definitely buy one. I don't think I'm going to see this in my lifetime though (I'm in my 40's).

      Do you own a Roomba? I don't. It's a huge liability and doesn't do the cleaning I want out of it, even at a sub-$1000 price point. The humanoid robot is clunkier, more of a liability, and will still refuse to do certain tasks.

      > Are you really telling me you wouldn't pay any amount of money to do menial housework? If not, why not?

      This is called having a live-in maid or a cleaning service. Even in the first-world, where there isn't a disfranchised rural population to provide cheap labor to the middle class (e.g. Philippines, most of LATAM 20 years ago) the service will be cheaper than the price of a vaporware bot [0]. Now, you might say the droid is cheaper if you want a live-in maid in HCOL area, but have in mind that this thing barely can fold clothes and fill a dishwasher (an actual domestic bot). Also it sometimes is actually a dude controlling it remotely.

      We would need bots of the level of that awful I Robot movie with Will Smith.

      And another thought: if the robot can do housework, can it do factory work? Fieldwork? Lawn care? What else can it do with zero modifications?

      That expands the market greatly.

      You couldn't pay me any amount of money to have a robot in my home if it's controlled from Elon Musk's data center.

    • adastra22 4 days ago

      No, I wouldn’t.

      For one, I don’t spend a lot of time doing housework. Just organize your life better.

      Beyond that, the cost would not be small. Based on current designs, operating costs would be thousands of dollars per month. I would not pay that.

      It would require a cloud controlled robot with cameras in my home. Why in the world would I want that.

      Finally, I already have dishwashers and laundry machines.

      • sejje 3 days ago

        Why thousands per month?

        Why would cloud connectivity be required? (I'm almost certain you're right, the big makers will require cloud--but that's not a requirement of the tech, is it?)

      • sejje 3 days ago

        I can't speak for the other guy, but as a person who manages humans at work: I'd rather have a robot at home.

        1) I live way, way out in the middle of nowhere.

        2) Humans are fickle, late, emotional. They have requirements in their own life that conflict with the jobs I want them to do.

        3) Taxes. I don't want to deal with this headache. 1099 my cleaner or whatever?

        4) In my version, the costs of owning the robot are less than the costs of hiring humans. If that wasn't true, then I'd reconsider. I probably wouldn't buy one until the cost switched like that, unless maybe it was open-source or something.

        Here's another way to think about it: Amazon is willing to pay workers to do the job, but they'd obviously rather have the robots do it. The robots work close to free, don't complain, and probably do a better job (at the jobs they're capable of). Why wouldn't they hire a human for that? A lot of the same reasons.

        It costs approximately $200 for our house to be cleaned once (by humans). We do it about once a month because we don't feel like spending $200 weekly). It would be great to have it ~continuously cleaned but we the cost/benefit isn't there for having a full-time person.

    The business case for humanoid robots is simple... for lack of a better term, they're robot slaves. Companies or governments can buy them once, pay relatively minimal maintenance fees, and have an army of workers that don't need a salary, never take breaks, never complain, never unionize, and do things faster and more accurately than most humans ever will. Any company that can move to robots, will move to robots.

    Imagine the profits companies will have when they can eliminate, or drastically reduce, their single largest expense... payroll. Not only the base pay, but 401K match, insurance, payroll taxes, etc. Poof... gone.

      I agree with everything you've said. To me the next question is: If nobody has a job, who will buy all the robot-produced goods?

      • sejje 3 days ago

        Some people will have jobs, even in the most robot-heavy vision.

        I don't know if it's enough people to buy the goods, but robot-produced goods should bottom out on price, closing in on the actual cost of materials/energy.

        • f30e3dfed1c9 3 days ago

          "robot-produced goods should bottom out on price, closing in on the actual cost of materials/energy."

          I don't think that's really true, or rather it's variably true along a continuum for different kinds of things. Some things sell for close to the marginal cost of production, others close to what the market will bear.

          For two examples, flat-screen TVs seem to be on one end of the continuum, iPhones on the other. Lots of other things are at different points in between. Robots won't eliminate demand for luxury goods, which are not usually near the marginal cost of production end of the scale.

          I don't know what it costs Apple to make an iPhone, but if they could cut it in half while people were still willing to pay $1,000, there's no reason to think they'd lower the price.

      The part that often gets left unsaid or glossed over is what the transition period looks like.

      Oh no, but Elon Musk tells us that out of the kindness of his heart we're going to have unlimited abundance. The same man responsible for taking away aid from thousands of the poorest people in the world through DOGE's interruption of PEPFAR and USAID.

No, I’m saying they haven’t made the case. Or at least the case that is being presented and sold to investors is complete BS.

For example, I work in deep tech and pay attention to the manufacturing industry. The idea that humanoid robots will replace, streamline and revolutionize manufacturing is a joke in that community. They’ve already long since replaced the humans with CNC machines, industrial (non-humanoid) robots, and 3d printing.

The humanoid robotics craze is a lot like the crypto craze. Pure vibes and motivated reasoning. Like crypto, there is actual value there, but way out of proportion to the hype.

      • zo1 4 days ago

        And yet such a HUGE amount of time is spent by families around the world (mine included) just moving laundry around in various states:

        Dirty -> Sort It Yourself -> Plan Washing Chunks -> Load into Washing machine -> Yay It "Washed it For You" -> wet pile of clothes -> Unload it -> dryer -> Dryer "Dries" it For You -> Fold It Yourself -> Storage.

        Now do this for a family with 2 kids that go to school. Washing is literally an hour or two of collective human time every day.

        I'd pay money to rather spend that time with my kids instead of yet another useless daily chore that can be automated.

        Now also apply the same logic to dishes, clearing up around the house, sorting cupboards, Driving!!, and a host of other things. The market is absolutely huge, and people are sticking their heads in the sand because they know that once this drops, humanity will reach an inflection point and all pointless manual labor will disappear, which means saying goodbye to cheap third world labor and only capital + raw resources + energy will be the only things holding back all scaling.

      Humanoid robots are a lot of sizzle-- they promise all sorts of flexibility, at the cost of hugely higher cost/complexity/unreliability.

      If you can scope your problem to some degree, you can probably make some purpose-built automation that won't look like a human, but will do the job competently and cheaply.

      • AuryGlenz 4 days ago

        Because, again, for home use we don't want a laundry robot, a dish washing robot, a cleaning robot, etc. We kind of have those (laundry machine, dishwasher, Roomba-types) but they all have big limitations. What people want is something that can do everything a human can do, so it can put away those dishes, wash a pan, clean the table, counters, etc. We've already scoped the problem and a humanoid-ish robot is probably the best option to do those things.
