I cann't disagree with you, ...
but I live in an surrounding where even 99% is using this M$-OS.
And I'm just too simple to get Linux working ;-(
I'm not a software programmer, and learning one computer language was
difficult enough for me. So unfortunatly, I've to stick to that language
which is be used by 100% of collegaes.

As I said before, my knowledge of languages (also human) isn't too well,
so I guess we've a misunderstanding here.
Simulating a RCX can mean many things:
1. simulating the software and viewing internal and external "signals"
2. simulating the IO-ports, so you can also test homemade sensors/actuators
3. simulating simple movements with a left/right motor or power/steering
motor
4. simulating bumping against walls (just binary bump or not bump)
5. simulating IR transmission between RCX and Tower or another RCX
6. simulating the real torque of motors (which is indeed impossible,
never seen 2 motors that where exactly the same)
7. simulating real mechanics, you're pointing to
8. simulating the heath development of motors of motors etc...
9. simulating the degradation of the batteries
10. ... many other things
What I have in mind, are the above mentioned points 1,2,3,4,5,9, ....
so NO real mechanics ;-(

yeah, that's difficult ...

| Hi all! (...) We don't need to simulate all of the mechanics because we've got the real thing. What about remote controlling the complete robot with the brain inside your PC? In the case of simulation we could degrade the RCX to a stupid IO device. (...) (22 years ago, 16-Sep-02, to lugnet.robotics)
