(...) Iain, This looks like a perfect opportunity to try using the servo circuit I designed! If I use some of the heavier duty servos I have in my stash, it could probably go direct drive. Each servo has a 180 degree range of motion, which might be (...) (25 years ago, 31-Jan-01, to lugnet.robotics)

Hi all, I have revamped my website. New look and feel. In the following weeks I will be posting pics and info for each stage of my Cyber Clinger - 2 RCX's, 1 Scout and a lot of sensors... The robot will be modeled after the Lego version "Robo goes (...) (25 years ago, 31-Jan-01, to lugnet.robotics)

(...) Yes, I understand. Lego created VLL for barcode reading (CodePilot, and then MicroScout). Barcode reading is error prone, so are other forms of serial communication. Through the use of the VLL Checksum bits and timeouts, one can invalidate bad (...) (25 years ago, 31-Jan-01, to lugnet.robotics)

(...) Good enough for me-- after all, any combinational logic construct (gates, but no registers/flip flops) can be represented as a ROM, and this is often done in practice. I can't imagine saying that just because one didn't represent it the other (...) (25 years ago, 31-Jan-01, to lugnet.robotics, lugnet.general)

(...) Well, yes - but then crystal oscillators are quite accurate (but crucially, not 100% accurate). You might have to run as long as one or two MILLION attempts before you see an error - but you *will* see an error if you do it for long enough. If (...) (25 years ago, 31-Jan-01, to lugnet.robotics)

I think I ought to buy another rotation sensor. This thing is *wild*. If you (...) (25 years ago, 31-Jan-01, to lugnet.robotics)

(...) That's exactly what my common sense made me believe. But various tests I did, using a dump of a Datalog with the timmings measured by the RCX, proved me wrong. Every Wait(10) was correctly measured as a Timer(3)==1, and every Wait(50) as a (...) (25 years ago, 31-Jan-01, to lugnet.robotics)
