    when computers and machines do humanlike tasks such as basic sorting of real world objects...

    and they don't get all hot and bothered when they do non-machine like tasks, such as lifting big cars and things?

    Robots that walk like people, human facial expressions on computer-graphics simulation.. they all generate so much interest among technical people.

    Perhaps, not being a technical person, I am more interested in the great alienness of machines. I am interested in earth movers at mines; the Big Dig in Boston; construction cranes; auto assembly lines; mainframes; enterprise-class servers; billion dollar electronic fund transfers.

    The replacement of humans in industrial processes with machines has always been an object of industrial design. The assembly line replaced the guild style craft. Instead of creating little portable machines that aided the watchmaker and the bootmaker in their old craft methodologies, inventors remade the ways of creating goods; those guild methods were replaced by roboticized methods of manufacture.

    I would rather see a chip in the head of the watch maker that gives him eagle eye vision, or an augmentation of intelligence or emotional sales skills in a salesperson, than something that would eliminate these people from their industries.

      Well, I used to work for a prof that did research in this area. That was five years ago, so I'm way out of date, but hopefully I can give you a bit of insight.

      A big use for this kind of thing is for part feeding, that is a method of orienting parts on an assembly line. There is mention of this on Dr. Resnik's web page. Basically, you have the problem of presicely orienting a whole whack of (possibly complicated) parts as fast as you can to present them to the next stage in an assembly process.

      Yes, a robot can accomplish this, but because of the motion that is involved they are slow, and because of the optical recognition involved they can bit, uh ... touchy :)

      One method of dealing with part orientation is by things called bowl feeders. They are a bit hard to describe in type, but imagine that you have a big steel drum with a spiralling track up the inside of the drum. By vibrating the drum you can make the parts you are trying to orient climb up the track (beleive me, this sounds wierd, but it actually works). By changing the shape of the track you can force incorrectly oriented parts to fall back into the bowl, thus filtering out parts that are correctly oriented. So, only parts that are correctly oriented arrive at the top of the drum.

      It's not quite as simple as that, but that's the general idea. Now, as well as this works (when it works), the problem is that whenever you change the shape of the part, you need to build a new bowl feeder! And building these things is not simple (or cheap).

      I beleive what Dr. Reznik is trying to do with this experiment is not to prove that you can move poker chips around, but that you can build a programable solution to this problem; you can build one machine that will sort anything, given the correct programming of the controllers, thus alleviating the cost of prototyping things like bowl feeders.

      So, to my mind, it's actually pretty spiffy, despite what others are saying here.

      I know I've left out some details, and I certainly haven't researched Dr. Reznik's work, but hopefully I've given you (and some of the /. detractors) some idea where this work is probably headed.

      The only thing I find a bit perplexing is, if he is proceeding towards the end that I've described, is how he is going to do this in three dimensions. Sure, he can rotate things in two dimensions, but what about more complicated parts?

      I should also add that watching one of those bowl feeders in action is actually pretty creepy at first. Parts move up the track, but nothing else seems to be moving (the vibration rate is quite high, so you don't really see it). Mind you, they are freakin loud :)

    People are correct in saying that robotic arms would be able to move bigger objects and is probably a cheaper solution. Apparently, UPM allows movement of more than one object at a time in a small area. If you have a robot arm, let's face it: you need room for it to move. This may be room that you don't have.

    Having said all that, I still don't know exactly what real world applications this may have. Would it be used to sort drugs? Maybe someone can think of a good reason to move multiple pieces of something at the same time. This is somewhat exciting, but we're years away from any practical application, especially since I can't even begin to think of one. :)

      Ok, first the full disclosure. I'm a grad student who worked with both John Canny (the advisor involved) and Dan Resnik (the builder of this cool device). http://www.cs.berkeley.edu/~jfc/

      The objections that I'm seeing seem to be of the following:
      * "It's not real--the videos are fake."
      No, it's real. The basic principle is this: if you take a table and shake it, stuff moves a little. If you shake it in a different direction, stuff moves in a different direction. Dan has figured out a pretty cool way of quantifying all this. He does a vector addition of several different shakes, and is able to therefore target the shaking.

      * Why is it cool?
      Well, first, because it's not obvious that it works. This is tricky math.

      * Yes, but why THIS?
      Because robot arms are a pain, and only manipulate one thing at a time, and they need a lot of elbow room, and a lot of motors, and they have to touch things. This requires four motors that JUST pulse in and out. It works on a flat table. Nothing touches except the table surface. This would be perfect for carefully-controlled environments like clean rooms (where you want to minimize the amount of stuff in the room), hazardous materials, and delicate objects. There's very little complexity, and because it's just a bunch of (tuned) vibrations, you could slap up a new one against a floor and it works.

      The chess demo is just showing that one can comfortably manipulate a large number of items.

      * Does anyone need to sort multiple things?
      All the time. Factory floors separate out rejects from working models. Recycling centers separate cans from bottles. Usually, they hire people to sort the stinking messes apart, and they use clever special-built machines to separate metal (use a magnet) from glass (heavier than plastic when crushed) from paper. This sorts on a smooth--therefore easily cleanable--surface.

      Dan now works for Siemens TTB, who are, among other things, very interested in small motors.

      * My toy did this.
      Yes, it did. But it did it in an extremely constrained way, and it probably took a really practiced flip of your wrist. And it probably did it in one dimension. (Dan has a little plastic train set that works on this principle).

      * This eliminates human jobs
      Not necessarily. It could work well in conjunction with a human job. Why do that annoying RSI-inducing reach/grab/sort when you can sit behind a desk, look at a video camera, and tick off the items on a screen? After all, image recognition isn't too good yet. The machine is responsible for the reach/grab/sort, and you don't have to wear a bunny suit.

    That's very impressive. I'd have thought that impossible.

    Recognize what they're doing. They're vibrating a rigid plate in such a way that one object, out of many, moves. The system that drives the plate can produce both small rotations and translations. The vibrations have arbitrary waveform, and are generally asymmetric. It's the asymmetry that produces motion. That's all.

    I could see this working for two objects, because you could vibrate the plate such that the center of rotation was under the one you didn't want to move, so it didn't go anywhere. But I had no idea how they make this work for N objects.

    The novel result in the thesis is section 6.1. Figure out how a "jet" vibration works, and you'll understand the whole thing. The basic idea is that a rotational vibration centered on the point at which motion is desired is superimposed on a translational vibration in the desired direction of travel. When both vibration functions are suitably chosen, there's a very unexpected property: the feeding velocity is small everywhere except near the center of rotation.

    This is counterintutive. You'd expect the rotational effects to be biggest far from the center of rotation, and zero at the center of rotation. Apparently the idea is that the forces induced by rotation interfere with the translational vibration that makes objects move. What puzzles me is that they're able to achieve zero feeding motion over most of the entire plane. But look at figure 6.2 in the thesis, showing the jet field.

    That's really neat. But I don't get it intutively yet. Can anybody else explain it more clearly?

Conference room tables that serve coffe (Again, assuming you do 95% of the work to get the coffee to the table.) The coolest thing about the chess thing is the piece recognition the computer does, which a camera is used for. The Post Office application is, admittedly a bit cooler but for the most part I'm not really overwhelmed. Just kinda whelmed...

The reason I have such high compression is I have very limited web-space. --Neil

    Call me a skeptic, but I would have been much more impressed if they had moved one thing at a time. Instead, if you watch the video, you see them moving everything on the table at once, with no real pauses between steps, and most of the pieces in multiple squares at once. There is also considerable collective drift. The text speaks of accurate positioning of individual pieces, but that isn't what I saw.

    Can someone please explain what's so impressive about this?

    The plate shakes; several objects move around randomly. They claim it's intentional positioning, but it doesn't look like it.

    I could do this myself. I shake my table, things move, and I say "Look! Each is moving on it's own vector!" Who would disagree?

    If they moved only one object, or moved objects from a specific point to another specific point, things would be different....

    What a disappointing reaction from /.

    This is real world engineering. It may be trivial to write software to manipulate objects on a GUI, but this application requires indirect mapping between vibrating transducers and deterministic motion of 1 object whilst N objects remain relatively stationary. Iterate this and you have arbitrary manipulation of multiple objects in Ďparallelí.

    Solving the mapping problem, and building a working demo deserves some respect. So you canít think of a decent application after 30 seconds thought, so it must be useless.

    The whole world of manufacturing is based on manipulation of components to produce a more complex assembly. The Universal Manipulator provides new method of achieving this and I am sure lots of applications will be found, because it is easily reprogrammable without retooling and faster than serial manipulation by a single positioning device.

    As an example, PCB populating involves a whole number of pick and place motions to position all the components on the board. If all of the mechanical steps could be replaced by simply dropping all the components on the board and shaking it for a while, assembly would be faster and machines would be cheaper and simpler.

    Apparently, Homer's been doing this for years. By the time he demonstrated moving a bowl of dip across a coffee table simply by stomping his foot, he had obviously had quite a bit of practice. Even Mr. Burns was impressed.

    Genetic programming to create optimal movement? (Score:0)
    by Anonymous Coward on Wednesday August 01, @10:37AM EDT (#123)
    Has anyone tried to use genetic algorithm evolution to find better motion algorithms? It seems like a great application for them, since you can set up a pretty simple "optimal" target case (the selected item or items move toward the goal position and and other items don't move), which you can use to measure the suitability of the algorithm. Of course, you may get really sick of puting pieces back in their starting positions until it comes up with a decent solution... Brett

    I had an electric football game back in the mid 70's that did pretty much the same thing. You set up the pieces, plugged it in. It buzzed and shaked, and the little guys moved around. A search for "ELECTRIC FOOTBALL GAME" on eBay turns up lots of the things.

    Intuitive thinking (Score:1)
    by kmferry on Wednesday August 01, @11:41AM EDT (#127)
    (User #461242 Info)
    The way to think about this intuitively is to think about your "knowns" in the equation, and how to solve for your "unknown". Your "knowns" are the following: 1)You have chess pieces set at initial positions, 2)You know where you want these chess pieces to go (final positions), and 3)you can get info on the materials involved as they can act as "dampers", and dampers affect the vibrations. Your "unknown" is the forced vibration input (i.e. how fast each motor spins at a given time). For those of you with a calculus background, you can see that this is a second order linear equation with constant coefficients ( g(t)=ay''+by'+cy ). Thus you can set up matrices using Mathcad, etc. to crunch the math...solving for the motor inputs for each unit of time.

    I'm sorry, but I think the video clearly showed how un-prepared this UMP was... I saw two pieces move at the same time, several times...

    How about putting Chess pieces on a mattress while people get their grove on?
