(...) I've come up with three AND gate technologies so far. Also I've come up with three OR gate designs too (those are differential output, plus I have a single pressure OR too). I've only come up with one differential XOR and a single pressure (...) (19 years ago, 15-Sep-05, to lugnet.technic)

(...) Not many efficient ones, but it very much depends on the type of logic, whether it's differential (a pressure hose and a leak hose to a cylinder) or single (a few switches daisy-chained for an "all legs up" condition) If anyone were to patent (...) (19 years ago, 14-Sep-05, to lugnet.technic)

(...) I understand that leg 0 is moved up forward then down, leg 1 is moved up/forward/down, leg2 is moved up/forward/down, leg 3 is moved up/forward/down, and finally leg 0, leg 1, leg 2 and leg3 are moved back. I don't quite understand why you (...) (19 years ago, 13-Sep-05, to lugnet.technic)

(...) Thanks Steve. Another thought- You know those long oval-shaped arms (one end bigger then the other) that connect the front half to the rear half? I bet there is a chain in there that drives the auger (or blades). Maybe it is the front engine (...) (19 years ago, 13-Sep-05, to lugnet.technic)

(...) (SNIP) (...) This one has moved away from my usual differential logic. Each leg module has a flip-flop for the foot and hip, which does 3 out of 4 movements and waits for the fourth to be done all legs together. I see how single switch AND (...) (19 years ago, 13-Sep-05, to lugnet.technic)

(...) I've never read anything to support this supposition. I've always thought scrapers mainly use mechanical transmissions. I know Caterpillar likes to put mechanical transmissions in things where other makers only use diesel-electric. I'm sure (...) (19 years ago, 13-Sep-05, to lugnet.technic)
