Hi All, Currently I am attempting to build an automated hump yard. The main problem I'm tackling is the RCX controlled motorized points.

You need gears or a cam that allows an adjustment in the distance from the centerline of the shaft. A 24 tooth gear and a 40 tooth gear would allow you to accomplish such action. I find the cam is very useful as the driven element. You can always (...) (25 years ago, 30-Nov-00, to lugnet.robotics)
