...and then, after lots of testing and verifications, you get the problem of
mechanical wear! Some designs are more sensitive to that than others. For
example my Archimede screw (http://philohome.com/gbc/gbc-screw.htm) that
initially worked reliably is now unusable after several work days at
LegoWorld... I tried to fix it but it seems it cant be done without dismantling
it completely and replace most parts.
Similarly the spybot train
(http://www.freelug.org/IMG/cache-500x143/st1-v-500x143.jpg) had a propulsion
transmitted by 3 z16 gears mounted on axle pins... after a while there was a
huge quantity of abs powder! Works better now with gears mounted on axles 3L
supported on both sides.
Worm gears are no better (of course!). This module
http://philohome.com/gbc/gbc-sweeper.htm has ground about one millimeter of half
bush and support axle joiner...

| (...) Yeah, that's a good point. I've yet to have a module fail due to wear, but for at least one of my modules I've actually found a dusting of yellow ABS under certain axles by the end of the day. I guess part of this is just due to the fact that (...) (18 years ago, 30-Jun-06, to lugnet.robotics)

Now that I have started writing, I'm not sure exactly where this is headed, but I have this need to try (...) (18 years ago, 29-Jun-06, to lugnet.robotics)
