- Well, it's good to hear someone from CMU calling Erebus something other than
- an unqualified success, though I'm not sure I would call it an outright
- failure.

- Oh, I see. When a large robot works (like the Ambler) that's evidence in
- favor of large robots. When a large robot fails, it "says little to nothing".

- The Prophet speaks! And of course, no other unforseen failures would have
- occurred either.
-
- Perhaps if there had been two Dante's, the other one might have made it
- further than 6 meters. And perhaps if there had been 100 of them...

- Here at JPL we have built and demonstrated numerous robots operating
- in field conditions. We've never been to Antarctica, but we have run our
- robots in Death Valley (in August, no less). That's about as real as it
- gets.
-
- I do not want to downplay the achievement of the Dante team. However,
- just because you have been to the South Pole and had your picture on
- CNN that does not give you liscence to run roughshod over other people's
- work. Perhaps small robots are the answer, perhaps they are not. But
- they are certainly not, as you often imply, a naive solution which can be
- casually dismissed.
