I had done a project that integrated the Neural Network and Fuzzy Logic into the RCX for Navigation by legOS. Of course, the network models are simple due to the limited recources. I do not have time to manage the materials and upload them yet. But (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

(...) The capacitor is very much polarity-sensitive. It has +/- polarity indicators on either side of the standard 2x2 9V terminal, as does the solar cell, and it will not work if the polarity is reversed. (24 years ago, 27-Mar-01, to lugnet.robotics)

This whole Lego capacitor thing strikes me as somewhat intriguing. The super-caps, which are doubtless used, absolutely cannot be charged backwards, they have to have the correct polarity. And all the Lego electrical "stuff" like the RCX sensors, (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

Its neat for putting things together quickly and I use the library import screen a lot to reuse bits from old projects. I'd like to hear about how other people use (...)

I think that a pBrick like RCX or CM isn't fast enough to detect PWM cycles. Don't know the speed of a legOS program. On top of that, I think that the sensors detect resistance, not voltage. You can do this test yourself, using two RCX's or one RCX (...) (24 years ago, 26-Mar-01, to lugnet.robotics)
