Some very well done modules Kevin. I really like the "Wave" module. It moves quickly enough to make it more interesting than a slower set of steps. Bryan (17 years ago, 5-Aug-07, to lugnet.robotics, lugnet.technic, FTX)

(...) Great stuff, I also like the wave very much, the movement is really smooth. I've wanted to do something like that for a while, but I'm still unsure how to drive the movement... how did you do it? You seem to use 3-way blades, am I correct in (...)

(...) It's actually pully wheels. The original idea came from (URL), the one I made is longer. (URL) This is how the pullys are attached. Since there was no room two join the two drive axles, the pulleys are also used to hold them together. Piece (...) (17 years ago, 5-Aug-07, to lugnet.technic, FTX)

(...) pictures of the interal mechanism? And how is it on jamming? I really like the way you left one corner of the lift tower open, it just looks so much better with the ball motion visible. When I finally get a ball pump working that I like, I (...) (17 years ago, 5-Aug-07, to lugnet.robotics, lugnet.technic)

(...) I have some more pictures uploaded; (URL) here> and (URL) here>. The cut-away part in the lift is actually from a shortage of 1x4 bricks, but I agree, it turned out nicely.

(...) Thanks! I knew of that site (which is very great GBC inspiration indeed), but I never really looked at the mechanism there. This is just too great to have any remorse shamelessly copying :-/ I wonder if regular cams (6575) might work too, I (...) (17 years ago, 12-Aug-07, to lugnet.technic, FTX)

(...) Speaking of remorseless shameless copying, I spent an hour and half last night trying to build the crankshaft. I can't figure out the pattern those pulley wheels are using, especially how much space is between them. It doesn't look like the (...) (17 years ago, 13-Aug-07, to lugnet.technic, FTX)

(...) It's hard to tell from that picture, but pause the video and you'll see the balls run up at a 6-stud spacing. That means the peaks of the wave are six studs apart. The cams are spaced with one pulley plus a half bush, so are spaced exactly one (...) (17 years ago, 14-Aug-07, to lugnet.technic, FTX)

I built it last night. My earlier problem was in trying to use 4-stud axles to hold the pulleys in their offset position -- this is hard to describe, but the gist of it is the axles sometimes got in the way of other pulleys and warped their (...) (17 years ago, 15-Aug-07, to lugnet.technic, FTX)
