So the radio-controlled robots were retooled, for greater safety. In the past, weak signals would keep the robots from getting orders for as much as eight seconds — a significant lag during combat. Now, the SWORDS won’t act on a command, unless it’s received right away. A three-part arming process — with both physical and electronic safeties — is required before firing. Most importantly, the machines now come with kill switches, in case there’s any odd behavior. "So now we can kill the unit if it goes crazy," Zecca says.
As initially reported in National Defense magazine, only three of the robots are currently in Iraq. Zecca says he’s ready to send more, "but we don’t have the money. It’s not a priority for the Army, yet." He believes that’ll change, once the robots begin getting into firefights.
