“Robot dogs” — four-legged headless machines mounted with cameras and sensors — may one day be prowling along the Southwest border, spotting undocumented migrants or sniffing out drug smugglers.
Department of Homeland Security officials have tested the 100-pound, four-legged prototypes in Virginia and Texas. Officials hope to equip the robots, developed by Philadelphia-based Ghost Robotics, with cameras and sensors to assist Border Patrol agents in detecting illegal activity.
