Hi,
After a while, a little under a fortnight, an analogue method has presented
itself to me.
Surprisingly i feel it is a better way than the digital method.
Its only errors would be in the wheel-to-ground traction, which can give
'slippage' between the relative wheel positions.
And of course, traversing hillsides obliquely where one wheel rises and falls
relative to the other, introducing a slightly longer path. This problem also
affects the electronic method.
I have not considered introducing a counter-effect to offset this last
innacuracy as i can think of no suitable sensor.
Regards, John
