Wanted to thank everybody for replies. I ended up attaching an 80-tooth
gear to the rear axle (wheels are on the front set) after extending the
axle. The rotation sensor is mounted on the chassis outside with an 8-tooth
gear meshing to the other gear, which gives me a 5:1 ratio or 80 (5*16)
rotation units (couldn't accomodate a worm gear to get more accuracy -
shucks ;-( ). Since all of the axles (from the two differentials) turn
synchronously (by virtue of direct gear meshings), I can get adequate turn
angle and displacement measurements.
Very nice!

| The drive system in my robot is an adder-subtractor (see (URL) which uses two differentials in order to get equalized forward/reverse drive while allowing turning and pivoting (turning in place). For navigational purposes, the robot should be able (...) (23 years ago, 9-Jan-02, to lugnet.robotics.rcx.legos)
