- Unless the 'failure modes' are on the order of "I've fallen and I
- can't get up!". This also assumes all of the small machines are
- identical and will haev the same failure mechanisms. Multiple,
- co-operative machines are more likely to be able to help each other

- This one is trivial to solve, the mother ship that lands the smaller
- robots has the large antennas, high power amplifiers, and even a lot
- of the 'brains' of the multiple smaller rovers in it's vicinity.

- I think everyone is setting up straw robots for the other side's
- viewpoint. Possible rover sizes range from the CMU Ambler and the
- Army's (future?) teleoperated bulldozers all the way down to the MIT
- microbots and Drexler's nanomachines. My own feeling is that a small
- number (say 3 to 6) of medium sized (say 3-4 feet on a side) vehicles
- can be very useful, but then that's the size vehicle I built for my
- Simulated Lunar Teloperations projects, and the _major_ size
- constraint on that was that it had to fit in the back of a VW Golf!
