The AX2550 Motor Controller has been installed in four of the 20 robotic vehicles that were vying for the $1M prize that DARPA was offering to the winner of the Los Angeles to Las Vegas race held on Saturday March 14, 2004. These vehicles had to find their way and drive the 210-mile trek without a human driver or operator, using solely their own sensors and computers to recognize and navigate through the difficult mountainous and desert terrain.
