Upright, wheeled, semiautonomous robots rolled their way across a dusty range in Las Vegas, Nevada, as a mock team of shooters mounted up for their attack.The robots took their places behind cardboard cover and began their own version of an ambush. The human team sped into the zone on two all-terrain vehicles and engaged. Through programming, the robots know when they're being shot at, from where and if one of their compatriots has been hit. They react accordingly. They seek cov- er and use obstacle-avoidance software to keep from running into each other or over the shooter, should they close the distance.The robots were on display for a shoot ing scenario at the Sig Sauer range day, part of the annual Shooting, Hunting and Outdoor Trade Show. And an estimated 6,000 U.S. Marines over the past year have had a chance to get some more realistic target practice than what they usually see in paper targets and specified, known distances.
