| | Automatic train switching with RCX
|
|
Dear all, we've built an automatic train switching mechanism using the RCX. It detects trains using reed contacts (cheap devices sensitive to magnets) and switches two points so that the train stops and another one departs instead. We've tried to (...)

(...) Another option would be to connect a single rotation sensor directly to the motor that turns your robot. (you may wish to gear it down) You could not detect the distance forward or backward (from the other motor), but you could calculate the (...) (23 years ago, 10-Jan-02, to lugnet.robotics.rcx.legos)

(...) I have done this, although not with a differential. My solution used a rotation sensor on each axel, and good navigation can be done with that. Since you can guarantee that both axels turn the same amount, a single rotation sensor should be (...) (23 years ago, 10-Jan-02, to lugnet.robotics.rcx.legos)

(...) Robert, I have been playing with this problem a bit. Another approach is to power each tread with a separate motor, use a differential assembly to add the shaft rotation from both sides and use a rotation sensor to 'control' to a zero (...)
