Hi all, I'm trying to control a polarity switch with a motor controlled by an RCX. The position of the switch is monitored by a rotational sensor. The problem I am having is how far the switch moves on return to the middle 'off' position, it tends to move way too far. I've tried slowing down how fast the switch moves by various gear/pully combinitions with little success. Has any done any work on this? Are there any istruction posted on motor control of the polarity switch? Thanks for your help, Roy

(...) Take a look at (URL). I controlled it with something similar to Robert Munafo's design (URL). Cheers, Hao-yang Wang (21 years ago, 22-Jan-03, to lugnet.technic, lugnet.robotics)
