So basically, when designing a mechanical walker, the use of these types of adder/half adder creations is to see how the machine will walk? I ask because I have never built a walker. (19 years ago, 12-Mar-06, to lugnet.technic, FTX)

(...) Well, technically, 1 + 1 = 2, or in binary, 1 + 1 = 10. The sum isn't 0, the S output is 0. ‹/nitpicks› This stuff is cool. I like your mechanical logic gates better than the pneumatic ones I've seen. Yours are definitely cheaper to build. (19 years ago, 10-Mar-06, to lugnet.technic, FTX)

Hi all, I've finally updated my mechanical logic gate pages with a couple of new (ish) creations. The XOR gate and the Half Adder. You can find them by going to (URL) and (URL) I'd stick in a picture or two here ... if I could figure out how ... (19 years ago, 8-Mar-06, to lugnet.technic, lugnet.announce.moc, lugnet.robotics)
