    Let me hold your hand as we stroll through it together, then:

    This is not a robot (in the opinion of the original poster and me) because it is neither autonomous nor does it have the capacity to be made autonomous-ish by adding sensors and a brain (microcontroller). It can only perform canned macro-functions and sequences of these canned macro-functions. Micro-scale control of its functions is not available.

    A programmable assembly-line robot is, however, a robot not because it's autonomous in itself (assuming you're talking about the arm / mechanical part), but because it could be autonomous if you grouped it with it's controller, which is a reasonable thing to do despite the fact that they tend to be seperated by some distance in practice, they key is they need not be. In most assembly lines, the robots are programmed to do repetitive tasks with minimal or no variation of behavior based on sensor inputs. But they could easily -- you just have to re-program the microcontroller (brain) and add sensors. So they are indeed robots -- micro-scale control of their behavior is available, and with inputs, a microcontroller, and some clever code, you can make an autonomous robot.

    Well, strictly speaking everything in the real world is analog, of course. But, in the way we're using the terms here, analog means made from discrete analog components and feedback circuits with fixed values, which are distinctly unlike the human's (and other animals') unique ability to vary the analog operations in such widely varying and relatively precise ways.

    Digital, as relevant here (like an Aibo), means able to be approximated by binary values and transformed by logical operations using digital circuits that drive digital-analog converters such as servos and motors with "digital" imputs and controls. This sort of thing lends itself very easily to programming that can be changed and modified easily, sensors added to the system with little impact or re-design needed, etc.

    My point was that analog discrete devices, like the ones used in this toy, tend to be only cheap enough to warrant a system price of $80 when they are the plain old-fashioned fixed values, which means the circuit made of these that controls the behavior is not variable (its behavior depends on these fixed values). It does one thing, and has a few circuits that it can shunt in an out to do several canned things. But making it do a new thing, even a slight variation is hard and expensive, and adding a new input from a new sensor, something trivial in most digital control systems (like an Aibo), is nigh impossible.

    So, again, the only way this sort of analog-circuit control system robot toy will help bring down the cost of other, digital processor-based robots, is if we find a way to make cheap discrete components with variable parameter values controllable by digital logic, and even then the savings would be pretty small. You still need the ASIC with the microcontroller in it. Maybe your servos and motors could be a bit cheaper -- maybe.

    If these motor skills can really be done at such a price, there's no reason why we shouldnt see pretty dramatic drops in the prices of the more expensive tech toys.

    Don't be so sure. These are analog control circuits, not digital logic. So there' s no CPU or microcontroller to program with autonomous-ish behavior. And theres not an easy (or cheap) way to control the analog circuits even with add-on digital controller of some sort or add new response behavior based on new sensor inputs -- the discrete component operating ranges are to small to produce the wide variety of behavior you can do with digital logic.

    So, if you want this toy to do something new, you can't just tweak some assembly code, or vary the pulse-code modulation signal to a servo, you have to design a new control circuit. There's the rub.

    Still kinda cool to watch an $80 robot do a little jig with decent dexterity. It's a great achievement in low-cost analog feedback control systems. If we just knew how to make cheap resistors and capacitors with wide ranges of easily-controllable parameters, we'd be seeing some major advancements spawning from this.. .

    You have a good point, but I think you're jumping too quickly to a solution in the wrong direction, IMHO. You want servers filtered and segregated by skill level. I don't think this will work. Here's why:

    Intermediate-to-advanced players will surely occasionally hop onto a n00b server to shoot some fish in a barrel, take out some frustration, test a new tecchnique, or whatever. This will annoy and discourage players who are "expecting" to do well because of server skill settings.

    Some new players may even incorrectly assume that they don't have to bother with the (relatively high) learning curve of the controls and coordination required for most FPS games.

    A sort of Peter principle kicks in: as soon as you have one or a few games where you start to do much better than the preset skill level for that server, you have to move on. It would be hard to tune the system to choose the "break-point" at a proper time for everyone. If I get lucky and a wild grenade kills 10 enemies, am I ready to move on? A tough AI problem, for sure.

    The idea of filtering by skill quickly gets reduced to filtering by score, or at best aggregate average scores. This can work if you have a game with uniqie id's and centralized tracking. But then you'll need to account for multiple player for the same game CD, which allows for "cheating" the system by creating new "n00b" accounts.

    Even if you work around the problems above, note that score is really not strongly related to player skill. Scores are more a combination of relative player skills, the maps, and playing styles used in each game. Bad players can get high scores and good players can gwet low scores, especially in team games, depending on the class and role they are playing.

    In fact, some team-based mods are now actually not tracking individual player scores, but only team scores. This is to encourage more teamwork and less Rambo-style play. Some players get very high scores by baseraping with planes or whatever, yet still play poorly (by definition) because their team loses, and they don't help. If team victory is the goal, individual scores don't do well to promote it.

    The above emphasise the problems with determining "skill" in terms of segregating servers and enforcing the segregation, and it also leads into my suggestion.

    With class-based games, you have the option of focusing on 5 or 6 different skill sets / strategies. If you're not the best/fastest twitch finger in the West, consider playing classes other than assault/soldier and choosing not to run head-first into the front lines. Maybe you would be better playing medic, or engineer, or artillery support. I play a variety of classes (mostly in BF1942), and each one is a very different experience requiring totally different skills and play styles. Please consider trying them all a little and see what you may have a natural knack for, and enjoy.
