What I suggested was that your rechargable batteries are at the
end of their lifespan.
Buy a set of regular NON-RECHARGEABLE batteries and see if everything
works OK then.
If it does then toss out your rechargeables and buy a new set.

That's definitely a symptom of dying batteries. They can't take the
load of driving your mechanism - the voltage drops - and because
rechargeables don't produce as much voltage as non-rechargeables in the
first place - the voltage drops enough to crash the computer inside the
RCX. The motors never get told to stop - and they can work at any
voltage (they just get slower and slower) - so they keep going.
So - go buy a set of normal, non-rechargeable batteries, if everything
works OK with those then buy a complete new set of rechargeables and
throw the old ones away.
They don't last forever.
