The science-fiction movie "Robocop" was set in 2029. But the St. Louis Police Department's request for robot drones to patrol the skies might make you believe a "Robocop" future could be here sooner than later.
City police Chief Sam Dotson says he hopes that robot surveillance drones could be patrolling the skies over St. Louis within a year.
When most people think about drones, they think about the predator and reaper drones armed with hellfire missiles that strike at Taliban areas in Afghanistan and Pakistan.
But the newest generation of surveillance drones don't carry weapons. And they're small ranging from the size of a small desk to a coffee cup.
