I agree with most of the other posts that say to find a good name you should be original, but I also believe that the name should relate back to your teams story.
Don't forget that sometimes a team names can come about in weird ways. In 2000, team 433 was called MINT (mounties interested in new technologies) because our highschool is Mount St. Joseph Academey. That year, because of some wiring problems, the robot caught on fire during a competition.

The girls on the team at the time decided that the next year, the team would rise from the ashes (literally) of our rookie season like a phoenix. We have been known as the Firebirds ever since
So don't be afriad to change your name after your rookie season. Just make sure when you do decided on your name, own it, with your spirit and T-shirts because a team name is just a name, however a "team" is a representation of the spirit and personality of a group of individuals who are proud to be -insert team name hear-
