Wow. I never noticed the rubber in those pulleys before.

So you insert the axle just far enough to engage only the rubber lining?
It seems that if you put the axle all the way through there is no slippage.

the pulley is not slippery enough.

The micro motor doesn't have an axle output, just a standard stud. David Kadansky wrote in message <3760AC13.5079426F@p...ox.com>... (...) (25 years ago, 11-Jun-99, to lugnet.robotics)

(...) The slippage is supposed to occur between the micro motor and the pulley, not the pulley and the axle. The micro motor uses a stud (rather than an axle) as its output, and you insert that stud into the rubber lining. Cheers, Hao-yang Wang (25 years ago, 11-Jun-99, to lugnet.robotics)
