Power Take off possibly? Hence the two sprockets with different alignments...

Maybe switching of power from drive to climbing mech?

That's the basic idea of power take-off, adding an application or switching the application of the motor. Kind of like gear shifting, except instead of switching gear ratios, it changes outputs of the motor. http://en.wikipedia.org/wiki/Power_take-off

Yep, this gearbox gives us a reduction of about 12:1 to drive (on 6'' performance wheels) and about 16:1 to the climber. One gearbox and lifter arm were able to lift 70+ lbs in our testing.

In case anyone was wondering, we chose to go with 4 rather than 6 cims for the PTO because math told us we could, and cims are always useful for other mechanisms.
