NASA just tested an insect-inspired swarm of drones a host “hive” drone, each carrying 25 little “CICADAS” that detach from its underbelly to fly around and learn about the weather and atmospheric conditions.
Each little CICADA is equipped with air pressure, wind speed, and temperature sensors, which activate as the tiny drones glide to the ground like confetti, steering themselves in circles as they catch drafts of wind and heralding progress toward ubiquitous drone swarms that collect data as they fill the skies.
The CICADA, which stands for “Close-in Covert Autonomous Disposable Aircraft,” was built by the U.S. Navy for purposes monitoring the weather.
“Cicada is a concept for a low-cost, GPS-guided, micro disposable air vehicle that can be deployed in large numbers to ‘seed’ an area with miniature electronic payload,” reads the Navy’s description of the CICADA, which goes on to describe them as tactical, flying circuit boards.
