Japanese Researchers Develop Sensor Skin

ScentCone writes "A University of Tokyo team has developed a flexible, laminated network of pressure and temperature sensors suitable for jobs such as robot fingers. Circuits as pressure sensors, and semiconductors as temperature sensors are not new, but the thin, networked laminate of the two is novel."

    Robots so far haven't been the best looking things, as their inventors rarely see a need to cover them up with "skin" or something that looks vaguely aesthetic.

    So maybe this will make new robots resemble something a bit more organic, by, say, colouring this stuff to look like human skin. I think this would go a long way in making them more appealing to the public.

      Its not just about making them more "appealing" to the public.

      This new "fabric" laminates the pressure and temperature sensing network together, so that both properties can be detected simultaneously, using carbon based circuits and semi-conductors, which is inexpensive to reproduce

      This would allow the scientists to measure more easily (if not more accurately), the effects a certain task would have were it performed by a human, the side effects certain working conditions may have (kind of prevention before cure), and in future they could add more sensors on these layers to measure other aspects (for example, radioactivity)..

      Ah, but would you restrict the sensors to just fingers/hands/feet, or go for the whole 'body' ?

      To be useful, covering the whole body would require millions of sensors, and somewhat impractical to implement and process.

      I agree with earlier poster, the best use for this, is in prosthetics. We already have artificial limbs that can be 'moved' via crude nerve interfaces, add this on and the limb becomes a lot more useful. Much more usful than a Honda-bot that can pick up an egg without breaking it.

      Robotic musceles are solved? Thats new to me.

      They are far, far away from being "solved". Atrificial muscels (made of fibers) are energy inefficient and bulky. DC-Motors are bulky and heavy, yet better in efficiancy still not good enough.

      And for the article: Its nice that they manufacture such a skin ... but how many degrees of freedom is it able to measure? 1 is definitly to few. How are the signals read? The have to be amplified a lot, so how many wires are needed? Wehere is the amplification done? Just imagine ous small finger -- is there inside enoug room for the bearing structure plus amplification-electronics plus wires?

      Actually I think there might be a way to handle so many sensors.
          for every few hundred or so have a very simple processor that just looks for sensors that need attention (nearing temp/pressure boundries, changing enough to warrent attention, ect.) then when something happens it sends a simple message upstream to a more important processor (HEY sensor #252 is getting hot fast!) that processor then converts the info from it's subs into more general info for the main system and passes it on (LEFT HAND MELTING!). Of course the higher processors should be able to set alert criterion for lower processors and even query for specifics, but outside of the main system focusing it's attention it mostly just processes simple all o.k. messages from a small handfull of surface sensor agregators.
          I know I'm rarely aware of more than a general sense of to what degree I'm comfortable unless I specifically focus such as when testing the water temp in the shower or when accidently stub a toe.

      Heh, yeah I've thought about this a bit. Two of my fantasy mad scientis inventions are an android and Power armor, which share some of these problems. The other is a time machine.
          It's a bit related to subsumption architechture in robotics, thought I didn't originaly think of it that way and intend to study more on that subject. It's just obvious to me that semi-independant semi-hiarchical controll/processing is the way to do it rather than try and do it all as one big cpu and software. Especially when you consider all the work the feet do keep you ballanced and moving smoothly while walking through 5 toes and the ankle pivot. Or all the work hand do in so many tasks.
          Teach the tiny components the details and the biger components then know just enough to order the next size down around and take feedback.
          To many layers could creat propogation delays and errors of imprecision, but then wires are faster than neurons and all sorts of minor errors that have to be constantly corrected 'in flight' occure in humans.
          If there is enough task specific learning capability and such at a low enough level the system could cope. Add in simple neural networks at say l2 or l3 and use GA's to find good fit baselines for them and the higher level heuristics have less to deal with specifics wise most of the time.
          Of course all these processors and various actuators will generate some heat (as might the power source), but if your emulating a human, a fluid cooled system (colored appropriately) could double as a mimic for a blood system and help provide 'body heat'. You could also pass cool air past some of these 'blood vessels' via a breathing mimicing system.
          Of course a mimic for the muscular system is a bit tricky. There are some pnumatic(sp?) muscle systems that somewhat behave like human muscles (rubber tubes in a mesh so that expaning the tubes shorten them) but I'm uncertain how thier strength and deformation properties compare to human muscles. Some other candidates are clearly not powerfull enough to do the job and if the same holds true for the phumatic muscles then more traditional motors and actuators may have to do some to most of the work with the other system being largely cosmetic in purpose. And of course the response time is important.
          And the problems with robotic vision are infamous, though progress is being made.
          It's all fun mental excersize though.

    For starters, I was just going for a +1 Funny, but alas it seems I've just managed to be cryptic instead.

    Second, if I'm to actually think seriously about it, whether the robot is pleasured is pretty much the last thing that comes to mind. Think of it as simply a feedback loop.

    Think of it in terms of game design. You could just put the NPCs standing there and not bother with issues like AI or realistic reactions. They're just NPCs, right? Thy're there to be slaughtered. They're no better than cardboard targets, right? WTF do you care if they even try to defend themselves, or their team mates? It's not like they really have feelings or any real team spirit or anything, right?

    Well, it turns out that nevertheless, people like it more when they see some believable reaction to their _own_ actions. If you gave someone a choice between two FPS games, (A) one where everyone sits around like cardboard targets, and (B) one where you can see reactions ranging from teamwork (suppression fire, flanking, etc), to panic, to whatever else, as a result of your actions, chances are they'll prefer B any time.

    Or if we're talking robots, take some fine creations as the Aibo or various others. Some people buy an Aibo instead of just a statue of a dog. The point is precisely that you expect it to react to the environment or your actions, rather than just sit there looking like a dog.

    So _if_ I were to manufacture a robot companion, I'd want it to act and react as much as possible as the owner's expectations of a real person.

    The keyword there being "expectations", rather than being actually indistinguishable from a real person. E.g., someone looking for companionship that way probably expects something more along the lines of "co-dependent" than a realistic woman impersonation like "wtf, you never have time for me. If all that matters to you is World Of Warcraft, then I'm packing my bags and leaving." Again, not unlike game design and AI design: you have to match what the player expects, rather than create a perfect simulation or AI.

    And _if_ that robot is also usable for sex, that would include sensory input and reactions for that. Ranging from moaning at the right time to pressure sensors to enforce some limits of what it's doing. (E.g., if it's giving the owner a hand-job, you don't want the robot to yank the guy's tool clean off.)

    So there you go. Does that satisfy your curiosity?
