Well, this ought to chill out anyone who was worried about a robotic uprising: our mechanical overlords may not kill us right away. At first, they just might zap us with a paralyzing burst of light.
The US Army's Aviation Applied Technology Directorate (AATD) plans to demonstrate the use of a 7.5 million candlepower strobe floodlight system mounted on board an unmanned air vehicle as a non-lethal crowd-control system," the always-linkworthy Flight International tells us.

But that's not the only flying robot / ray gun combo the U.S. military is examining. The Air Force is also toying with the idea of mounting its Active Denial System pain weapon on a drone, too. Just so the robots can make us feel like we're on fire, before they temporarily blind us.
