(...) Believe me that I have tried a lot of combinations. Also your and my idea of "little slack" may be quite different. But it is true that I have never done an exhaustive study on the subject. I usually just give up on getting it perfect and rig (...) (24 years ago, 5-Apr-01, to lugnet.robotics, lugnet.technic)

(...) If you use a tensioner arrangement, then it works OK. I haven't really played around with much more than simple weight tensioners (mostly for conveyer use...the catapilar treads are great for that!), but imagine you could come up with a (...)

Dean, it's probably dumb luck that the two drives on the piece I'm working on have little slack. Yet, with LEGO beams and blocks you can't use every gear combination; there are published beam/block/plate combinations that let this or that pair of (...)

(...) You're kidding, right? It's almost impossible to build a geartrain using the chain that doesn't have tons of reversal delay. The links seem to be designed in such a way that they don't work well with technic beams and gears. I always have (...) (24 years ago, 5-Apr-01, to lugnet.robotics, lugnet.technic)

There is one real simple way to eliminate backlash: Use LEGO's 'small-link chain' with their normal gears as sprockets. I paid CAN$7.00 for 135 links from Pitsco-Dacta's Canadian vendor. There is absolutely NO backlash. Mind you, the gearing problem (...) (24 years ago, 5-Apr-01, to lugnet.robotics, lugnet.technic)

Well, with all the fuss over the Droid Escape, I decided to buy a few, and seeing how everyone else was coming up with all these nifty things to use the cylinder bits for, I figured I may as well add to the melee. A while back someone in (...) (24 years ago, 5-Apr-01, to lugnet.technic, lugnet.starwars, lugnet.technic)
