Using two rotation sensors should do the job nicely, at a higher cost
however. But you can connect them directly to the RCX.
About that : did anyone build a reliable (and cheaper) rotation sensor
replacement? Why not using a lego wheel with holes and some kind of
mouse light sensor :
Light out ->0 || 0-> Light sensor (->to the rcx)
||
||------ rotation axis
||
||
How about converting this sensor information to the 4 state (?) rcx
rotation sensor pulses?

| This isn't suitable for Vlad's original problem, but I do want to point out that motors can be adapted as cheap rotation sensors (actually rotational velocity sensors, which is the first deriviative of what a normal rotation sensor gives you) by (...) (25 years ago, 13-Nov-99, to lugnet.robotics)

| Hi all! I had an idea last night, and I think something good might come out of it, with so many smart people around! *s* I need a way to track the position of my robot, and I realized that attaching the PC mouse to it might do the trick! Without (...) (25 years ago, 11-Nov-99, to lugnet.robotics)
