Ok, so it's nothing to do with nqc and not much to do with mindstorms, but
here's a nice bit of elementary physics I came across while playing with my
RIS:
Take two 9v dc lego motors like the ones you got with the RCX. Stick something,
a wheel or a cog, on the axle of each motor. Something the motor can be turned
with; it's best to gear up a bit so that you get a sufficiently high speed on
the motor axle. Don't connect either motor to the RCX, and make sure the wheels
on the separate motors aren't touching in any way, but interconnect their
inputs with a lego wire thingy. Now turn one motor axle manually and watch what
happens on the other.
Good eh?:-)
I 'll leave you to work out what's happening for yourselves..

| I think that's a really good idea. I tried it, and found out that the motor recieving power spins slower than the motor you spin. This is about 4:3. This could be a really good speed reduction technique that doesn't use gears, or you could power (...) (24 years ago, 13-Jan-00, to lugnet.robotics.rcx.nqc)

| (...) I was just trying out having 4 motors to power 4 wheels (one per wheel) and I saw this effect. I had the two motors on the right side both attached to output A and the two motors on the left side both attached to input C. But now I am worried (...)
