Engineers create drone that becomes nearly invisible mid-air
Researchers at Northwestern University have built a drone designed to be almost impossible to see while flying. The device, called "Phantom Twist," utilizes motion blur to create the appearance of a light haze. Instead of the standard four-rotor setup found on most quadcopters, this drone operates with a single motor and propeller, capable of spinning at a rate of 25 times per second.
