CIA's Secret Robot Dragonfly Spy from the Cold War

2024-12-16

In the 1970s, the CIA secretly developed a miniature robotic dragonfly, dubbed the "insectothopter," for espionage. The device used laser reflectors as microphones, analyzing laser beam vibrations to capture sound. While successful in lab tests, its inability to cope with real-world wind conditions led to the project's termination. Nevertheless, this ambitious endeavor laid the groundwork for modern micro-drone technology and highlighted the intense technological competition of the Cold War.
