(...) My suggestion: Touch: Have the track elevated, and free to move up and down (1 'hinged' joint). Then have your touch sensor below the track. Light: Hard to get accurate, repeatable measurements. If light level changes, requires recalibration. (...) (25 years ago, 29-Dec-99, to lugnet.robotics, lugnet.trains)

FWIW I haven't tried this yet myself, but its very typical to use light sensors for this sort of thing in HO scale model railroading. There are a lot of advantages to "contactless" detection. On the down side, you need to minimize interference from (...) (25 years ago, 29-Dec-99, to lugnet.robotics, lugnet.trains)

(...) I don't have a design, but I do have a comment, to wit: With a touch sensor you are committing to a fixed dimension SOMEWHERE unless you get quite clever. It may be in the width of the vehicle, it may be in the height, it may be the depth of (...) (25 years ago, 29-Dec-99, to lugnet.robotics, lugnet.trains)

I'm using Mindstorms to control Lego trains. Does anyone have a design for using a touch sensor to detect a train passing? My intuition is that the touch sensor could be more reliable than the light sensor (plus I have two touch sensors and only one (...) (25 years ago, 29-Dec-99, to lugnet.robotics, lugnet.trains)
