DARPA announced Monday the 40 Grand Challenge teams selected to advance to the National Qualification Event at the California Speedway in Fontana, September 27 to October 5, 2005. Half of the the 40 teams will be selected to compete for the $2 million prize in the Grand Challenge event on October 8, 2005. DARPA selected the semifinalists from a field of 118 entrants, using results from on-site visits where vehicles had to autonomously navigate a narrow 200-meter course that contained turns and randomly placed obstacles. The 40 semi-finalist teams come from a variety of backgrounds including universities, individuals, corporations, and a high school. See slashdot for more info.
