Why humanoid? Surely there must be a superior physical form factor than one mimicking human anatomy. Is it just supposed to be more psychologically acceptable?

There probably (certainly) is. But if you want to build a multi-purpose platform, you’ll soon be faced with a dumb challenge: nearly all interfaces (door knobs, taps, electric switches, cutlery, sponges, every single button out there, pillow cases, wrenches, hammers, signs…) are made for humans. Placed at human hand level. At human eye level.
Nearly all environments (houses, streets, sidewalks, factory floors, offices, toilets, bathtubs,…) are made for humans. Wide enough and tall enough (or short enough, for bathtubs) to accommodate human bodies.
So until we can find one or more form-factors superior enough to justify we adapt everything around it or them, betting that the easiest way to build a single multi-purpose platform able to do most things (and not n platforms for n+ use cases) is to borrow the shape most things are made for wouldn’t surprise me. Plus, you get a wider market.
And then, once you have happy-ish customers, figure out which of these human attributes and shapes aren’t actually needed to do the job.
Never said it was interesting. Just that it’s easier to sell tech that fits your customers' environments than to get customers to overhaul their environment to fit the unproven tech you want to sell them.
Most fixed infrastructure like switches and buttons that can be operated with a single hand are amenable to any robot with at least one hand. We've had Sawyer demonstrations operating tools clearly designed for humans for more then a decade ago and Mobile Aloha had demonstrations showing how it can operate the switches of an elevator just fine. None of these are humanoid robots.
The moment you have mobile tools, whats the point in forcing the robot to hold them using a human hand? You can put them on a tool changer now or have a gripper that works for the specific task. Why does a robot need to hold a wrench using a humanoid hand?
>Nearly all environments (houses, streets, sidewalks, factory floors, offices, toilets, bathtubs,…) are made for humans. Wide enough and tall enough (or short enough, for bathtubs) to accommodate human bodies.
Uhm, now we're getting into stupid territory. All of those environments have flat floors. Flat floors are not an environment that are exclusively built to accommodate human bodies... The flat floor is designed for ultimate flexibility. It can be used for anything. Furniture, wheelchairs, wheeled robots, furniture on rolls, animals, and also humans.
All of the environments you've listed should preferrably be wheelchair accessible for disabled people (in terms of locomotion at least).
>So until we can find one or more form-factors superior enough to justify we adapt everything around it
Is this some kind of joke? Factories already make heavy use of UGVs and stationary robot arms and build custom end effectors for them. It's also an extreme strawman to suggest that wireless/electronic interfaces require finding a "superior form-factor" to the point that it feels insulting. There's also often an easy wheelchair accessible equivalent. E.g. a button to activate the electronic door opener at wheelchair level can still be at a comfortable height for standing people.
>And then, once you have happy-ish customers, figure out which of these human attributes and shapes aren’t actually needed to do the job.
So solve the impossible (come on you know it's hyperbole) first, only then can you build a simpler system.
I think its incredibly unreasonable to suggest that you need to solve every single problem ever encountered in human existence to be allowed to solve one much simpler problem.
I’m not arguing that humanoids are the only robots that can operate in human environments, nor that specialized robots shouldn’t exist. We already know they should, and do, and work very well.
I’m saying it depends on what you’re after.
If you want a specialized machine, then by all means optimize the form factor for that task.
If you want a general-purpose platform, then you’re faced with a near-infinite variety of environments, tools, and situations: homes, offices, hospitals, factories, hotels, streets…
Almost all of them were designed around human reach, dexterity, height, mobility and perception.

It doesn’t. The wrench was just one example among many. Nearly all our tools and interfaces are designed around human hands and bodies. If a different manipulator works just as well across all of them, great. My point isn’t that it must literally be a human hand.
> I think its incredibly unreasonable to suggest that you need to solve every single problem ever encountered in human existence to be allowed to solve one much simpler problem.
That’s not what I’m suggesting.
I’m saying it’s a deployment strategy. Start with the form factor that’s already compatible with the largest installed base of tools and infrastructure. Not because it’s mechanically optimal, but because it minimises the amount of adaptation required from the market.
And enables you to sell to markets you aren’t even aware exist.
If, over time, you discover that hands don’t need five fingers, legs don’t need knees, or an entirely different morphology delivers much better performance, then you have both the experience and the demonstrated value to justify changing the robot, or even convince your customers to change the environment to fit a better robot.
They’re basically trying to go for the "one size fits most" of robotics. And yes, we both know how well that usually fits anyone.
I’m not convinced either, but I can understand the logic.
There are just a few reasons - humanoid make sense, mostly for multi purpose tasks - where if you want a robot to be multi-job, do almost everything a human can do at work --
If you want a weld you need a 1 arm robot, if a robot to weld, then stack, then push parts on a cart across the factory - then sweep up, then etc.. etc.. perhaps a humanoid is alright.
There will definitely be too many people comfortable with ownership / master relationship with a humanoid robot that will do their bidding.
For multi-purpose tasks, human hands and arms are excellent, but only 2 are too few for many tasks. Humans very frequently need to have specialized gripping tools in order to accomplish tasks that cannot be done with only 2 arms, or they must work in pairs.
A good mobile multi-purpose robot should have 3 arms, or 4 arms for symmetry.
Human legs are normally not necessary. A mobile robot would just need some means to raise and lower its wheels, so that it could step when ascending or descending stairs.
A human head is not useful. The place for the "brain" of a robot is in its "chest", because robots do not have the limitations of living beings, where the very slow propagation speed of the nervous signals forces the nervous systems to be concentrated in the proximity of the main sense organs.
Instead of a head, one should have a couple of mobile arms with video cameras at their end, somewhat like the mobile stalks of crab eyes.
Of the components of a human, only the hands and arms are models useful to imitate. Cephalopod-like arms would be even more versatile than human-like arms, but it is likely that they would be much more expensive at similar performances.
Having the size of a human and human-like hands and arms is good for working in environments designed for humans, but having the shape of a human has no purpose.
I understand the argument but its honestly ridiculous in my eyes. How about a set of arms that can reach into dishwasher and stack dishes and a washer/dryer to fold laundry... Except even without solving the bipedal movement, that doesn't exist at a consumer price point.
Why are we pretending the hardest version of this is close to existing?
It doesn't need to be at a consumer price point first, it needs to replace a human at an existing warehouse or manufacturing role first, and that's achievable in the next two years at this point.
When you have arms that can reach into the dishwasher, you're also going to want them to put away your dishes. And so suddenly they need to get up high. And you're not going to have a SECOND set of arms at your washer/dryer to fold laundry, you're just going to buy a second DLC for your existing robot. And it needs to get between those places, so if you have stairs, wheels don't cut it. You need a bipedal robot very quickly.
Ok, so your idea is to sell a machine without software and then hand wave the software part away by saying it will be released at a later date? Sounds like a scam to me. You'll just end up with another AMD situation where the company is only interested in selling the hardware and has zero interest in developing the software, because it costs money and can only ever generate revenue by selling more hardware, which will make the hardware focused company feel vindicated in deciding to not put effort into the software.
My idea? No. I'm pointing out that if you release something capable of loading a dishwasher and putting away dishes, it could be as little as a future software improvement to make it do something else.
I am familiar, I'm a big fan of Dean Kamen's work. So far, we haven't seen a single wheeled stair climbing vacuum cleaner, even though the original iBOT is 23 years old.
That solves the horizontal mobility problem. And then you have cabinets - and wheels don't solve the vertical mobility problem. So then you need a scissor lift on those wheels, or a hydraulic lift.
The robotics nerds always end up back at bipedal because it's vastly simpler once you're already solving arms.
A scissor lift or some other thing seems a lot simpler than trying to allow for a bipedal robot to knee to reach things close to the ground. Or if legs are the best option, why not a quadruped? Much more stability with a lot of the same advantages.
Use wheels and buy two if you have to...the Roomba solution. Besides, why do you need to solve stairs the hardest way possible, a fully bipedal robot, before it moves past vapor?
Human spaces are built for humans. Outdoors cars and quad coppers are a great form but constrained by stars, doors, and low ceiling makes them a poor fit.
Alternatively a 2 foot tall or a 20 foot tall humanoid robots aren’t particularly useful. But a good enough 5-6 foot tall humanoid robot can be swapped into an assembly line wherever a human is currently working without redesigning that workspace.
There probably (certainly) is.
