$6,500 for OpenArm v2. Incredibly smooth movement, 4kg of load per arm. Its unclear how far the level of autonomous control has come so far. The video shows mostly tele-operated operation. I have to agree with other comments here that folding laundry is the killer app.

sschueller•about 11 hours ago

I don't understand why everyone wants to build a laundry folding robot that is humanoid when we generally build purpose built machines which can do a much better and quicker job.

I want to toss dirty laundry into a hopper and have it come out clean and folded at the other end.

There is no reason to use my existing washer and dryer that are designed for human use.

AngryData•about 4 hours ago

Yeah but nobody has had any successful ideas for sorting and folding random fabric and clothes in any other way. Its not that people wouldn't mind a non-humanoid laundry robot/device, the problem is nobody has found any other solution to solve the problem, human hands and minds and methods are the only currently known solution.

One would expect it to at least have calibration and inverse kinematics solved. That's still a massive pain point for the SO-ARM101 despite it being so common now, since there's no base_link to gripper calibration nor sag compensation and every center offset stacks.

Lerobot banked on having full DL control of each joint so they wouldn't have to do that properly, but now VLAs just use inverse kinematics as a crutch and predict gripper offsets, so we're back to square one.

drapado•1 day ago

Hi! do you have any references for VLAs using inverse kinematics? I'm very curious and can't find much

moffkalast•about 24 hours ago

I'm not super up to date on new releases, the one I'm most familiar with is X-VLA which predicts gripper poses and relative movement deltas for kinematics to move to instead of joints, and trains on forward kinematic gripper poses. I think Intern and Octo have the same approach.

altruios•about 18 hours ago

Respectfully, that's the corporate-washed killer app.

Intimacy between people in a long distance relationship: that's the killer app.

The term for that is teledildonics

... and the "at least historic" lack of "app/service" security related to this...

Uh, the main site appears to be down (and most wouldn't click on the link, given it's name) - but you can read about a project here:

That's a niche inside a niche. It's a step up from existing solutions, but not an enormous one.

fhn•about 11 hours ago

take "people" out of that equation would be even better

8note•about 15 hours ago

probably not quite.

intimacy over onlyfans with a guy in india pretending to be the woman is the proper killer app.

XorNot•about 17 hours ago

No it's definitely folding laundry.

My intimacy with my partner in a short difference marriage would improved it we could eliminate folding washing from the weekly chores.

failbuffer•about 14 hours ago

Have you tried getting a folding board or folding table? Helps accelerate the process and produces neater results. I love mine!

mrguyorama•about 15 hours ago

So, uh, have you tried just not folding laundry?

I think it's funny how often "Folding Laundry" is brought up as the critical use case as if that's a labor function that needs to be done in the first place!

Some of us already live in the Utopia of not folding laundry!

I'm not advocating, but pointing out how silly it is that the supposed linchpin of the end of human labor is a completely voluntary and unnecessary task. I get why it can be a good example, because it's common and "hard" in that computery way that seems like it shouldn't be that hard, and that it's supposed to represent all the other hard problems of housework.

But we know what the household robot industry considers "solved" to look like, and I'm not that satisfied with roombas, and knowing that, is $6000 for something that could fold your laundry really that much better a proposition than just being wrinkly sometimes? Downey produces a product that you spray on a clothing item and stretch it and it stops being wrinkly. Totally unnecessary, but way cheaper than $6000.

CompoundEyes•about 16 hours ago

In the movie Idiocracy they have a dispenser with fresh clothes to put on covered in advertising — assuming free. I’m surprised that doesn’t exist and perhaps made of recycled plastic?

It's cleaning the dang bathroom.

We've come a long way from watching 50x speedups [1] to real-time [2] videos of watching robots fold clothes, student-style.

Off-topic, but even though it was 16 years ago, the robot looks so beautiful and well-designed. It looks so aesthetic!

eichin•about 15 hours ago

It's the https://en.wikipedia.org/wiki/Willow_Garage PR2 (according to the paper linked in the description.) It definitely had a design style - which mostly expressed "we have a lot of money to sink in to robots" rather than "anything we are doing has a market" though to be fair they had a lot of interesting spinoffs - just not from the robot itself :-)

bluebarbet•1 day ago

To me it does not seem like progress that, on a stressed and finite planet, humanity might "need" an energy- and resource-intensive machine to complete a task as physically undemanding (and even frivolous) as folding a sheet. But here we are.

nater5000•about 20 hours ago

People are consuming useless plastic toys at an unfathomable rate. It's one example, but it likely contributes so much more to the stress on our planet than actual robots capable of providing actual utility by a huge margin. I'll question the use of humanity's resources once we reel in behaviors like that a bit.

dan-bailey•about 19 hours ago

You leave my Lego collection out of this.

showerst•about 20 hours ago

Have a couple of kids and then revisit this comment =). Laundry folding is probably family's most disliked trivial chore, and becomes a non-trivial chore if you have a large family with lots of activities that generate a constant stream of dirty uniforms and gym clothes.

embedding-shape•about 23 hours ago

I see people taking cars for distances that would take 10-15 minutes to walk. If we're hunting to cut down on inefficiencies, there is a lot of stuff we could attack before a robot arm becomes impactful enough to care about.

brookst•about 19 hours ago

I genuinely don’t understand this binary thinking. You could easily turn it around: if we’re cutting down on inefficiencies, laundry folding robots will give people more time to exercise.

Or, why bother going to the gym if you don’t eat healthily? Or, why bother eating healthy if you don’t go to the gym.

Not trying to give you a hard time specifically, it’s just a pattern that I feel left out of. If A and B are both improvements over status quo, why does one obviate the other?

King-Aaron•1 day ago

I just want my laundry folding robot to run slower than me, and not be able to do karate backflips etc in the event of some undesired scope creep happening one day.

nannal•1 day ago

House scale Faraday cages and an airlock for fiber optics. Should be sufficient until maybe 2032.

I've got a collection of socks needing darning!

brookst•about 19 hours ago

Oh great now you’re outsourcing the “where the hell did the other sock go and why are there always odd numbers coming out of the dryer” existential crises to AI. Is there no aspect of the human experience you won’t cede to machines?

ethanwillis•1 day ago

  A fully open-source humanoid arm for physical 
  AI research and deployment in contact-rich 
  environments.

When will someone release this but for deployment in target-rich environments?

hobofan•1 day ago

I think in target-rich environments, the humanoid form is pretty easy to beat.

One step closer to becoming Adam Jensen

Or Smasher, there's a few Adams we're taking steps towards

Smasher's too bulky and his quips ("You look like a cut of fuckable meat") don't match his hardware.

i asked for this

prometheus1992•about 20 hours ago

i'm not really sure if people are being sarcastic about laundry folding being the real application of this because I have never felt in my life that i want a robot folding my laundry. i actually love folding my laundry.

AngryData•about 4 hours ago

I don't like folding laundry, but that's why I just lay all my clothes out flat, which still negates the desire for a robot to do it.

slfnflctd•about 20 hours ago

It's a huge milestone for robotic capabilities more generally. This particular problem has been discussed a ton in robotics communities. It requires a gentle-but-firm grip and extreme dexterity across a wide range of shapes, sizes, weights, densities and material types.

If a somewhat affordable robot can fold some of your laundry in a reasonable amount of time, all of a sudden there are a lot more new and useful things it can do as well. It's a metric.

Plus there are also people who don't like folding laundry. Like me.

prometheus1992•about 19 hours ago

>>> If a somewhat affordable robot can fold some of your laundry in a reasonable amount of time, all of a sudden there are a lot more new and useful things it can do as well. It's a metric.

I see, is it like arc agi but for robots? wouldn't the companies just laundryfold-maxx their robots then?

throwup238•about 16 hours ago

That would mean maximizing robotic dexterity, not just control, which means improved hardware. Roboticists would be ecstatic with a laundry-maxxed robot.

slfnflctd•about 18 hours ago

My current opinion is that trying to 'maxx' in this area (as has been done with other benchmarks) would actually bring enough other use cases with it as a side effect that it would be worthwhile.
