Roland Piquepaille writes "Two years ago, I told you that the Gladiator Robot will join the Marine Corps. Now, the Pittsburgh Post-Gazette reports that the six-wheeled combat robot, designed and developed at Carnegie Mellon University (CMU), made its debut last week. This new U.S. unmanned fighting vehicle can fire machine guns, nonlethal sting balls or tear gas. It could be used for reconnaissance, surveillance and direct-fire missions. CMU will deliver six prototypes of the three-ton robots by 2007 to the Marine Corps, which could deploy about 200 Gladiator vehicles in combat zones around 2009 if the prototypes work as intended. Each Gladiator should cost between $300,000 and $400,000." For more details see Roland's blog. There is also an older robots.net Gladiator article.
