Berkeley Gets Willow Garage Robot To Fold Towels

kkleiner writes "Researchers at UC Berkeley used Willow Garage's PR2 robot to fold towels. The UCB programming used some innovative visual scanning techniques, allowing the PR2 to pick up a towel, find its corners, and fold it on a table perfectly. According to the paper presented at the 2010 ICRA (PDF), the robot successfully completed 50 out of 50 attempts to fold a single towel, and also folded 5 out of 5 towels when they were presented in a group. Is watching a robot do laundry really that exciting? Hell yes — wait until you see the video! UC Berkeley used a Willow Garage robot to develop their own sophisticated robotics program. That validates the whole premise of the PR2 — faster development by letting researchers use a common platform. Score one for open source robotics!"

      The smug guy says "I know you can't fold a piece of paper more than 7 times."

      You say "oh yeah? any piece of paper? How about $20 says I can do it 9 times?"

      Then you go get a roll of toilet paper, and you roll it out. You can find rolls of industrial-grade toilet paper: you know, the itchy horrible stuff, that are 2000 feet long, and 0.004" thick. Then you start folding in half. It takes a lot of walking, but you end up with something a couple feet long and a couple inches thick at 9 folds. If you get adding machine paper, or even better punch tape from old computers, which is both longer and thinner (some tapes) you can do better yet.

      Cost/efficiency? Probably cheaper to have poor immigrant labor continue to do it -- and that's for hotels that don't outsource linens. FYI, linens are already robotically pressed and folded in the big laundry service facilities.

      Hospital linens are, to my knowledge, pressed and folded in a sterile environment by robots, then packaged to maintain sterility before delivery back to the hospital. I know this is true for my two local hospitals, not sure about others.

      You don't need this level of sophistication just to fold towels. The robot could just kind of flatten it out by tugging on different corners until it's flat, and then grabbing two corners and folding it over.

      Even easier would be just a big machine that pulls in a bin of linens and separates them onto rollers, which deposit them in piles.

      TFA states that the robot is not the best model to fold towels. It does demonstrate "open source" robotics. At one time, computers were dedicated, single use, machines. Now, an off-the-shelf robot can be programmed for various tasks. That's the point.

      Whoever doesn't think this is amazing needs to pay attention to a young child sometime. This thing has more programmed dexterity than a 3-year-old: my daughter isn't stupid or anything, but I doubt she could neatly and consistently fold a towel or washcloth. Ask any parent: having young children "help" with the laundry ends up being more work.

  15. Are robots safe for family use? by gillbates · · Score: 2

    With the recent invention of a laundry folding robot, many are asking if robots are safe for family use.

    A local area woman is questioning the safety of robots in the home after her husband built one to mow the lawn. She says the only thing it did was scare off the neighbor's dogs, and she can't imagine bringing a robot into the house.

    Still, others think the technology is promising. Scientists say that robots are getting better all the time, and recent improvements have made chainsaw and butcher-knife fueled rampages a thing of the past. "We're learning more about robot psychology every day," says a prominent climatologist, " And things are getting better. Do we completely understand erratic behavior? Well, not completely. But we're working on it, and erratic episodes are much fewer and farther between. I've had a robot living with me for almost 6 months without incident."

    Local men are enthusiastic about laundry robots, as most of them want to spend less time doing household chores. A few of them are already using the robots. One even taught it to mow - though he warned our correspondent to stay off his lawn.

    Still, many people are uncomfortable with having a machine become a part of the family. Some say it just isn't natural to talk to a bucket of bolts, and feel awkward addressing as master something they regard as an overgrown tin can. Whether they're bound for the trash heap, or ruling the roost, one thing is certain: robots are changing lives in unimaginable ways.

    Well, sure, it'd make it easier, but now that this technology has been shown - technology that can fold a solid-colored towel or a multicolored towel or anything - it must be developed and furthered as-is. If companies were to try to lock us into their towels so that our robots and towels would be compatible, we'd have comparisons to Microsoft and complaints about technology being held back and whatnot in an instant.

    If we know that the robot can fold any towel, any color, any pattern, then that's what has to be developed in order to look good, impressive, or any other adjective that would be favorable to a manufacturer.

      Your linked videos are all examples of extremely impressive hardware and motion control. You don't want a PR2 if you're interested in motion control and dynamics problems, you want one to interact and manipulate in a similar manner and with similar capabilities as a human torso and arms. The PR2 platform isn't for industrial use, and it's not supposed to walk. It's to give researchers a common-ground solution with extensive software to work on AI problems with, not traditional control problems.

      The industrial arms are very accurately playing back a path that was programmed in by hand - I certainly don't want to downplay how impressive that demo is, but there's not a lot of 'intelligence' about 3D motion control. The pick and place machines do need some very basic vision tasks to identify and track the targets on the assembly line, but in general the problem is solving motion control (plus with the Flexpicker I think a terrific mechanical design helps.) Likewise bipedal locomotion is a difficult problem, and the dynamic stability of the humanoid robot is a great feat, but again a different field from the towel folding task. To balance/run as in the video requires no external sensing, only internal inertial sensors and a pre-programmed gait (technically it's not running, to run both feet need to be off the ground at the same time - watch closely, it's actually a fast walk.) I think they are all very impressive, and I have no wish to imply that they are any more/less impressive than towel folding, just that they are different problems.

      Yes, I agree, a 50x speedup is painful and completely impractical. The cool thing here is the object recognition and manipulation, especially with soft, flexible objects. Identifying a random towel, picking it up and finding all four corners, then grasping two adjacent corners and folding twice, all dynamically is not an easy task. There are tons of easier and faster ways to fold a towels automatically, but none of them could work from an untidy pile of different types of towels piled on a table - they'd all need some special loading mechanism and take up half a room. In theory this robot could wander around a room actively looking for towels people had left around and do the same thing - that's what makes it interesting. And no, I'm not saying we should ever plan on using expensive humanoid robots solely to pick up and fold towels, it's just cool to know we're one step closer to the day when they -can- do it.
