Nano drones are tiny unmanned aerial vehicles that typically weigh less than 250 grams. They are designed for various applications, including surveillance, search and rescue, and environmental monitoring. Due to their small size, nano drones can easily navigate through tight spaces and are often equipped with cameras and sensors for data collection. These drones are powered by advanced battery technology and can be controlled remotely or programmed for autonomous flight. Their compact design makes them suitable for indoor use and in areas where larger drones cannot operate. As technology advances, nano drones are becoming increasingly popular in both commercial and recreational settings.
