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.

I've been playing with the following design to try to overcome the
problems with getting the robot to drive straight while using an A B
Differential drive train (ie left side wheels driven by motor A, right
side by motor B) and to get consistent turning.

This is described in Mario and Giulio Ferrari's excellent "Building
Robots with Lego Mindstorms".
