I would have built it, but while waiting my opportunity, I was doubly inspired: I
combined the  micro-rover concept with Ben's Rock Stupid Rover and came up with:
The Autonomous Mini-Rover! (Also known as the Rock Stupid Ant).

No scanner, no digital camera. No time to LDraw it. But I did come up with two
major innovations (for me, anyway):

1) No turntable needed! More precisely, the differential *is* the turntable. I
meshed the 24 tooth differential gear to an 8 tooth gear, which was fixed to the
cross-axle hole in a triangular plate.

2) I used a micro-motor axle-pulley for the Rock Stupid program 3. I attached it
to the inside end of one rear axle and inserted the inside end of the other rear
axle about 1/4 stud length into it. The result: limited-slip!

Hey, the micro-rover idea was Ben's, too! Wow! Keep up the mind storms, Ben!
