Coming soon to a 'military style checkpoint' in a city near you :
From Wired :
The 350-pound MAARS (Modular Advanced Armed Robotic System) machine can carry a 40mm grenade launcher or a M240B medium machine gun. Or, if the robot's operators want their killer 'bot to be a little less-lethal, the thing can be equipped with a laser dazzler, a loudspeaker, or pepper spray.
