Here is a CNET report on the latest breaking news in the Pentagon’s urban grand challenge:

“The Defense Advanced Research Projects Agency (DARPA) said Friday that it has whittled down the contestants for its upcoming urban robot race from 89 to 53 teams via qualification events,” writes CNET’s Stefanie Olsen. “Among the 53 teams are the Stanford Racing team (winner of the 2005 DARPA Grand Challenge–a desert robot race across 132 miles), Princeton University and Team MIT.”

For more indepth coverage of the Princeton team’s stereo-vision strategy, see Kevin Coughlin’s report in the Star-Ledger.

“The biggest challenge is the system integration–getting everything to work together,” Princeton team spokesman Gordon Franken tells Coughlin. “Over the past several weeks, we’ve been making progress towards that. Now that it’s for real, we have to buckle down and speed up our development.”
