Enter the Darpa Grand Challenge DARPA – Defense Advanced Research Projects Agency DARPA – Defense Advanced Research Projects Agency The U.S. Congress allotted 1 Million Dollars to the winner of the 2004 challenge. The U.S. Congress allotted 1 Million Dollars to the winner of the 2004 challenge. Nobody won! Nobody won! In 2005, the prize money was upped to 2 million. In 2005, the prize money was upped to 2 million.

It’s a hard problem!!! What is the Darpa Grand Challenge? What is the Darpa Grand Challenge? Why they have a qualifier! Why they have a qualifier!
