It would be nice to have a shorter name.  :-)

I found the overall resistance of the add/sub transmission and final drive
gearing, etc. when using tracks to be too great for one motor. This was the
largest detractor from it's utility (the fact that only one motor supplies
the driving force). It seemed to work OK with wheels.

How will the adder/subtractor help with your need for feedback in the turn
?

Separate issues, the adder/subtractor (is there really not a better • existing
name for this device btw?) is to deal with the slight variations in motor
power that prevent a truely straight line.  Though this is really not a big
problem with this configuration, because the resistance of the front wheels
to slipping sideways makes the curve entirely unnoticable over less than • 2-3
meters.


Will you use your modified rotation sensor to somehow achieve this ?

Yes, this part already works.  The axle of the fifth wheel goes directly
through the improvised rotation sensor, so when the bot is turning I get
narrow pulses as that wheel tracks around the circle.
