A few months ago the Defense Advanced Research Projects Agency, or DARPA, announced the Grand Challenge, a Las Vegas to Los Angeles road race in which a road race in which all the contestants have to be “autonomous motor vehicles” that can drive and navigate entirely without any human control. The prize for this robotic Cannonball Run is a cool million bucks, which apparently attracted so many entrants that DARPA had to winnow the field to just nineteen qualifiers, though they may had six more teams to make it an even twenty-five. The race is still on for March 13th of next year and we’ll have full coverage here on Gizmodo.
