- Kerien Fitzpatrick of CMU sez:
- > Those of us at the FRC knew this project was extremely risky
-
- Frankly, I don't think the lesson here has anything to do with small vs. large.
- I think it has to to with two things: (1) funding realities and (2) reliability/
- redundancy.
-
- CMU took on this project knowing that it was risky and that they
- had little time and money to make it work. That they accomplished what they
- did with those limitations is, I think, quite impressive. However, the negative
- publicity for CMU and especially NASA was a big risk; putting themselves on
- TV for everyone to see their failure was worse, and then NASA claiming it as
- an unqualified success topped it off. That was enough to get a very negative
- editorial on the local paper. I think the political/funding lesson is that if
- you've got high risk, little time, and little money, don't take it! If you must,
- then hope no one notices :-)
-
- The technical lesson is not big vs. small. It is reliability/redundancy. The
- CMU folks say they knew they did not have adequate redundancy, and we can all
- see that now. Let it be an example to be cited when asking for redundancy in
- a system. If you want to get redundancy with small robots, that's fine if they
- can do the job.

- Nuf said.
