It looks as if each week there’s a brand new video of a robotic folding garments. We’ve had some incredible demonstrations, like this semi-autonomous video from Weave Robotics on X.
It’s superior stuff, however Weave is much from the one firm producing these sorts of movies. Figure 02 is folding clothes. Figure 03 is folding clothes. Physical Intelligence launched their flagship vision-language-action mannequin, pi0, with an amazing video of a robot folding clothes after unloading a laundry machine. You’ll be able to see robots folding garments live at robotics expos. Even earlier than all this, Google confirmed garments folding of their work, ALOHA unleashed. 7X Tech is even planning to promote robots to fold garments!
And moreover folding precise garments, there are different clothes-folding-like duties, like Dyna’s napkin folding— which ends up in what might be my prime robot video of the year, demonstrating 18 hours of steady serviette folding. So why are all of those robotic manipulation corporations abruptly into folding?
Purpose 1: We mainly couldn’t do that earlier than
There’s work going back over a decade that exhibits some quantity of robotic garments folding. However these demonstrations had been extraordinarily brittle, extraordinarily sluggish, and never even remotely manufacturing prepared. Earlier options existed (even studying based mostly options!) however they relied on exact digicam calibration, or on rigorously hand-designed options, that means that these garments folding demos usually labored solely on one robotic, in a single setting, and should have solely ever labored a single time—simply sufficient for the recording of a demo video or paper submission.
With a bit of little bit of assist from a creatively patterned shirt, PR2 was folding issues again in 2014.Bosch/IEEE
Check out this example of UC Berkeley’s PR2 folding laundry from 2014. This robotic is, in reality, utilizing a neural community coverage. However that coverage may be very small and brittle; it picks and locations objects in opposition to the identical inexperienced background, strikes very slowly, and might’t deal with a variety of shirts. Making this work in follow would require bigger fashions, pretrained on web-scale knowledge, and higher, extra normal methods for imitation studying.
And so 10 years later, with the suitable demonstration knowledge, many various startups and analysis labs have been capable of implement clothes-folding demos; it’s one thing we now have seen from quite a few hobbyists and startups, utilizing broadly comparable instruments (like LeRobot from HuggingFace), with out intense specialization.
Purpose 2: It seems nice and folks need it!
Many people who work in robotics have this ‘north star’ of a robotic butler which may do all of the chores we don’t need to do. Point out garments folding, and lots of, many individuals will chime in about how they don’t ever need to fold garments once more and are able to half with mainly any amount of cash to make that occur.
That is essential for the businesses concerned as properly. Corporations like Determine and 1x have been elevating massive quantities of cash predicated on the concept they’ll be capable to automate many various jobs, however more and more these corporations appear to need to begin within the residence.

And that’s a part of the magic of those demos. Whereas they’re sluggish, and imperfect, everybody can begin to envision how this know-how turns into the factor that all of us need: a robotic that may exist in our home and mitigate all these on a regular basis annoyances that take up our time.
Purpose 3: It avoids what robots are nonetheless dangerous at
These robotic behaviors are produced by fashions skilled through imitation studying. Trendy imitation studying strategies like Diffusion Policy use methods impressed by generative AI to provide advanced, dexterous robotic trajectories, based mostly on examples of skilled human conduct that’s been supplied to them—they usually usually want many, many trajectories. The work ALOHA Unleashed by Google is a superb instance, needing about 6,000 demonstrations to discover ways to, for instance, tie a pair of shoelaces. For every of those demonstrations, a human piloted a pair of robot arms whereas performing the duty; all of this knowledge was then used to coach a coverage.
We want to remember what’s onerous about these demonstrations. Human demonstrations are by no means good, nor are they completely constant; for instance, two human demonstrators won’t ever seize the precise similar a part of an object with sub-millimeter precision. That’s probably an issue if you wish to screw a canopy in place on prime of a machine you’re constructing, however it’s not an issue in any respect for folding garments, which is pretty forgiving. This has two knock-on results:
- It’s simpler to gather the demonstrations you want for folding garments, as you don’t must throw out each coaching demonstration that’s a millimeter out of spec.
- You should use cheaper, much less repeatable {hardware} to perform the identical process, which is beneficial if you happen to abruptly want a fleet of robots accumulating hundreds of demos, or if you happen to’re a small crew with restricted funding!
For comparable causes, it’s nice that with fabric folding, you possibly can repair your cameras in simply the correct place. When studying a brand new talent, you want coaching examples with “protection” of the area of environments you count on to see at deployment time. So the extra management you could have, the extra environment friendly the training course of might be—the much less knowledge you’ll want, and the better will probably be to get a flashy demo. Hold this in thoughts once you see a robotic folding issues on a plain tabletop or with an especially clear background; that’s not simply good framing, it helps the robotic out quite a bit!
And since we’ve dedicated to accumulating a ton of information—dozens of hours—to get this process working properly, errors might be made. It’s very helpful, then, if it’s straightforward to reset the duty, i.e. restore it to a state from which you’ll strive the duty once more. If one thing goes improper folding garments, it’s high-quality. Merely decide the fabric up, drop it, and it’s prepared so that you can begin over. This wouldn’t work if, say, you had been stacking glasses to place away in a cabinet, since if you happen to knock over the stack or drop one on the ground, you’re in bother.
Garments folding additionally avoids making forceful contact with the setting. When you’re exerting quite a lot of stress, issues can break, the duty can change into non-resettable, and demonstrations are sometimes a lot tougher to gather as a result of forces aren’t as simply observable to the coverage. And every bit of variation (like the quantity of pressure you’re exerting) will find yourself requiring extra knowledge so the mannequin has “protection” of the area it’s anticipated to function in.
What To Look Ahead To
Whereas we’re seeing quite a lot of clothes-folding demos now, I nonetheless really feel, broadly, fairly impressed with a lot of them. As talked about above, Dyna was one in all my favourite demos this yr, largely as a result of longer-running robotic insurance policies have been so uncommon till now. However they had been capable of show zero-shot folding (that means folding with out extra coaching knowledge) at a few totally different conferences, together with Actuate in San Francisco and the Conference on Robot Learning (CoRL) in Seoul. That is spectacular and really very uncommon in robotics, even now.
Sooner or later, we must always hope to see robots that may deal with tougher and dynamic interactions with their environments: shifting extra rapidly, shifting heavier objects, and climbing or in any other case dealing with opposed terrain whereas performing manipulation duties.
However for now, do not forget that fashionable studying strategies will include their very own strengths and weaknesses. It appears that evidently, whereas not straightforward, garments folding is the type of process that’s simply very well fitted to what our fashions can do proper now. So count on to see much more of it.
