I am not totally sure if this would work... but it is an idea I've been tossing around my team:

-Gear Chiaphua motor *up* to drill motor's free-speed of 20,000 RPM (1:3.64?).
-Send output of drill motor and Chiaphua motor to drill motor transmission.
-"Four-Wheel-Tank-Drive," the output of the tranmission goes to a double-hubbed shaft. Each hub has a chain to one wheel. (We did this last year with just a drill motor, worked well).
-Repeat for other side of robot.

Now, my only questions are:

-Will the tranmission handle the torque? I think so... we've seen the Fisher-Price and drill motor go through the drill motor tranmission without a problem... the input torque shouldn't be much higher in this case.
-Will we pop the breakers too much? The dual-motor assembly claimed to not trip breakers because the current was distributed among a number of breakers... BUT the Chiaphua motor has a stall current of roughly double that of the Fisher-Price. Of course, the output of the Chiaphua could always be toned-down in the pBASIC code...

Warning: This is *NOT* my area of expertise... can somone with more know-how in this matter comment on the viability of this idea? 8)
