Race
A Google Talk video about the DARPA 2005 race is available at YouTube
The route to be followed by the robots was supplied to the teams two hours before the start as a computer file with GPS coordinates, one every 72 m (237 feet) of the route, with more frequent waypoints in difficult patches. Some teams used topographic maps and aerial imagery to manually map out and program precise path and speed settings. Once the race had started, the robots were not allowed to contact humans in any way.
Each robot started at a different time and was "paused" for different amounts of time during the race; DARPA compensated for the staggered start times and subtracted the pause time from each robot's total to derive its final official time. The $2 million prize was awarded on Sunday, October 9, 2005.
The 2005 competitors were much more successful than those of 2004; only one failed to pass the 11.84 km (7.36 mi) mark set by the best-performing 2004 entry, Sandstorm. By the end, 18 robots had been disabled and five robots finished the course. On the first day, Stanley from Stanford University, and H1ghlander and Sandstorm from Carnegie Mellon University, finished within minutes of each other, with Stanley crossing the finish line first. Kat-5 from Gray Team started much later, but finished in a comparable time. The race paused overnight with one competitor, TerraMax, left on the course at mile 83; TerraMax had the stage to itself on Sunday as it belatedly rumbled home.
The winner of the 2005 DARPA Grand Challenge was Stanley, with a course time of 6 hours 53 minutes and 8 seconds (6:53:08) with average speed of 30.7 km/h (19.1 mph). CMU's Sandstorm followed with 7:04:50 at 29.9 km/h (18.6 mph) and H1ghlander at 7:14:00 at 29.3 km/h (18.2 mph). Gray Team's Kat-5 came through at 7:30:16 with average speed of 28.2 km/h (17.5 mph). Oshkosh Truck's Terramax finished at 12:51 and would not have been eligible for the prize because it exceeded the ten-hour limit.

Famous quotes containing the word race:
“Why should a man desire in any way
To vary from the kindly race of men,
Or pass beyond the goal of ordinance
Where all should pause, as is most meet for all?”
—Alfred Tennyson (1809–1892)
“For it is the nature and end of this relation, that they should represent the human race to each other. All that is in the world, which is or ought to be known, is cunningly wrought into the texture of man, of woman.”
—Ralph Waldo Emerson (1803–1882)
“This race is never grateful: from the first,
One fills their cup at supper with pure wine,
Which back they give at cross-time on a sponge,
In bitter vinegar.”
—Elizabeth Barrett Browning (1806–1861)
