Yes - but it doesn't tell me the distance travelled - I need that too.
Still, I guess that using one sensor in the differential for steering
and one on *one* of the wheels for distance would work better. I guess
that the fact that the differential sensor wouldn't be rotating very
fast would also reduce the risk of dropped counts when driving really
fast.
Hmmmm - good idea....but I still need two sensors.
