Social Robot?

smashr writes "Researchers are currently putting the finishing touches on robots that will be attending the AAAI (American Association for Artificial Intelligence) conference this year as part of the AAAI robot challenge. In addition to robots wearing tuxedos and serving drinks, several robots designed to actually register themselves will be participating in the conference. One such robot is GRACE, being built by Carnegie Mellon University and the Naval Research Lab (among others). GRACE features a digital face and speech recognition to interact with people attending the conference. (She even runs Linux!) Her goal is to register for the conference, give a speech and answer questions. Stories at: Pittsburgh Post-Gazette, CNN.com, and USA Today."

      I'm not saying that the short-term goal isn't a laudable one - or at least a stimulating intellectual exercise. I'm more concerned about the long term. Do we WANT robots performing tasks for non-experts? There are more than enough human non-experts around, and we keep making more.

      ... we need to be able to communicate with them more naturaly, and that means includes gestures and expressions.

      Gestures and expressions are just another form of communication, and if you want to use them to communicate with your robot, be my guest. But gestures and expressions are extremely subtle (fractions of a centimeter in eyelid position can communicate volumes) and alarmingly variable, at least as humans use them. They also very subject to contextual cues. I expect that getting a robot to reliably recognize and interpret human gestures and expression will be far more difficult that getting it to recognize and interpret human speech. With speech we at least know most of the rules. We're still learning about nonverbal human communications ourselves.

The speaker demonstrated that indeed, she had managed to make the eyes more or less move in a natural way, but despite her efforts, I think most of the people in that room would agree that it still looked bad. She kind of appologized for it and said that you realy ought to track the eye lids, the frowns, the cheaks and all that... to get a realy convincing AI eye simulation. On top of that, the eyes have specific behaviour that diverge wildly when the person is engaged in a social pattern, or when they are saying something. For instance: Studies have shown that one tends to look more to the left while thinking about social stuff, while looking the other way when thinking about some technical details. Things can of course be reversed, but these tendencies to stare into infitity in a particular direction exist. They come natural to us, but if you think about it it's rather odd.. Even males and females don't do the same things with their eyes.

      So, without wanntig to diss on your remark, because you are right in many ways: while we may seem to be doing rather average reading the face of someone, it is much more likely that it is due to the fact that we don't know the person that well, don't know how to give an appropriate response, instead of being unable to read their face, that causes all these human issues. Maybe one day we will be having stupid arguments with robots, who knows..

      Hozever, imho we're still a very long way from truely intelligent behavior, because a) you need lots of context and b) you need lots of noise. Both of them are impractical for current silicon. The best quantum computer can deal with just 8 bits.. not terribly impressive..

      Much like a car, to give it "personality" would move it from the first case to the second. Thus when you give a generic machine a specific voice, it is (usually) female).

      But, as with all usage, it is up to the user. There is a strong push for gender neutral language in most things. The problem is that in cases that are purely up to personal taste, these rules apply.

      So you can't tell someone to not make their robot feminine. But you can tell someone to make their manual not masculine.

    Her goal is to register for the conference, give a speech and answer questions.
    I realize these are not easy tasks, but I have to wonder what challenging goals will be like in the future. Will we be reading an article on Slashdot.NET in 2050 that talks about a robot's goals at the conference including:
    • Driving itself to the conference in an inconspicuous, beat-up old 2040-model car?
    • Spilling its drink on an attractive woman's shirt and taking first-person-perspective photos of the cleanup efforts?
    • Fooling the attendees into believing it is a real person?
    • Fooling the other robots posing as attendees into believing it is a real person?
    • Fooling the attendees into believing they are real people?
    By those standards, registering oneself for the conference, giving a speech and answering questions seems easy.

  38. Laser rangefinders? by iamroot · · Score: 2, Informative

    "Looking over photos of the convention center in Edmonton, one of Simmons' fears is the center's glass elevators.

    Grace uses floor-level laser range-finders to find her way around; the laser beams go straight through glass, rather than being reflected as they are with other obstacles."


    I can see the laser rangefinders at the bottom, but it also has a bunch of ultrasound transducers in the middle, and some other lens(laser scanner?) above those in front. The glass shouldn't be too much of a problem provided that the ultrasonics are working.

    Sonar does have some problems, but it works well enough on the robots I've seen/used/built. The ultrasound clicks they make can be annoying, but it works. At a university I toured once, they were demonstrating some robots, a heathkit one, and two custom ones which looked exactly like GRACE, execpt they had thermal, visible, and UV(I think) cameras, 24 ultrasonics, laser rangefinders, a 3D laser scanner on top, and no screen. The robots were roaming around, and greeting people. They didn't seem to have any problem avoiding obstacles, it was actually kind of funny when the heathkit said "Pardon me." to a supply cart:)

  39. Read article? by SectoidRandom · · Score: 2

    Well I hate to be anal about a joke, but the CNN article actually mentioned that the researchers hired Drama Students to help teach the 'social skills'..

    That is interesting in itself. I guess these geeks see their weaknesses quite well?
