I don't have the book either. Did Mario and Giulio seem to think this
selectable torque locking helped in helping a robot travel straighter
or turn more consistently? I had initially intended this to be a sort
of transmission to give the option of giving the robot a bit more oomph
when travelling forwards or backwards with MotorC but realized that it
could also help compensate for torque differences between Motors A+B.

I think I've seen some designs around that duplicate the function of
the differential using a more linear gear arrangement (ie. can build it
with stock RIS kit parts). Try doing a search for: "Limited Slip
Differential" on Lugnet.
