Sorry if I'm a little late getting to this thread -

It's possible to approach this problem mechanically.  I used a
gear - switching setup similar to the shuttle / the supercar to
enable four motor outputs, two at a time.

To do this, I ran the output of motor A and motor b into parallel
axles in a gear box.  I mounted the shuttle-style 16 tooth free-
spinning gears on the axles, and used the little slider-clutch
thingy to lock the rotation on one gear on each axle at a time.

Finally, I used motor c to drive the clutch apparatus - both clutches
at the same time.  The result is that you can use A and B to drive
either one pair of outputs or the other.  I built a simple tank
chassis (driven by one set of outputs), and a grabber claw (up-down,
open-close) with the other.

and you realy need 2 motors (at least) to make your robot pre form a multi
task function.

        So this is my solution to this problem.  Get the lego RC racer to drive
your robot around.  Then your left with all 3 outputs on the RCX.  Last
you can get the lego mindstorm remote to excute you robots programs from a
distance.

any feedback on what you think of this would be gerate.

thanks
