Of 195 teams originally submitting race entries, DARPA, a part of the Department of Defense, chose 118 for further review based on vehicle designs and capabilities.

DARPA Grand Challenge 2005 is a field test of autonomous (driverless) ground vehicles to promote the advance of autonomous vehicle technology.

Teams vying to compete in the Grand Challenge develop their vehicles without government funding.

By 2015, the Pentagon hopes that using autonomous military vehicles such as TerraMax will help save the lives of military personnel.

"Being chosen by DARPA for a site visit is a huge first step and represents tremendous work by our team, both here at Oshkosh Truck and with our partners at Rockwell Collins and the University of Parma, Italy," said Don Verhoff, Oshkosh's executive vice president of technology.

"Based on the success of our TerraMax vehicle at last year's Grand Challenge, we're optimistic about our chances this year."

In May, DARPA personnel will evaluate the autonomous capabilities of each of the 118 qualifying vehicles on-site, including their ability to follow GPS navigation and avoid obstacles.

Only 40 teams will advance to DARPA's National Qualifying Event (NQE) in Fontana, Calif., in September. Of these, the top 20 teams will advance to the Grand Challenge on Oct. 8, 2005.

The team whose autonomous vehicle completes the Grand Challenge route the fastest within 10 hours will win $2 million.

In 2004, TerraMax was one of only seven entries to complete the 1.3-mile qualifying course for the Grand Challenge.

The platform for TerraMax is Oshkosh's combat-proven Medium Tactical Vehicle Replacement (MTVR), which was originally built for the U.S. Marine Corps and has been used extensively in Afghanistan and Iraq.

For the 2005 Grand Challenge, TerraMax has been given rear-wheel steering for improved maneuverability.
