Gordon, That is a good question. And I agree, there isn't much out there in this regard. In my book I talk about very simple (1D) robot navigation - remembering a place that you went to and going back to it. As far as more complex navigation goes (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

(...) The solar cell is part no. 32339, and the capacitor is part no. 32342. (...) Ok I unscrewed the capacitor's housing to get a better look. The main capacitor is a "Gold Cap" brand electrolytic, 2.5V, 1F (!). It's soldered to a small circuit (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

(...) That sounds about the right number. Whether it's enough to cover the cost of driving it depends on the nature of the vehicle. If it's something that only goes in straight lines then in can adjust the panel one time - and then only have to make (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

(...) Do you have the Lego part numbers for these? Is the capacitor like the commercial MaxCaps or SuperCaps? If so, we use these for NVRAM backup and could use them or might make them available to interested people. Thanks Bruce Boyes ------- (...) (24 years ago, 26-Mar-01, to lugnet.robotics)

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)

Yes, I also like the static facilities of message-boards, newsgroups and mailing-lists, because it becomes a searchable info resource.
