Nano drones are tiny unmanned aerial vehicles that typically weigh less than 250 grams. They are equipped with advanced technology, including cameras and sensors, allowing them to perform various tasks such as surveillance, mapping, and environmental monitoring. Their small size enables them to navigate through tight spaces and access areas that larger drones cannot reach. These drones are often used in fields like agriculture, where they can monitor crop health, and in search and rescue operations, where they can locate missing persons. With ongoing advancements in battery life and flight stability, nano drones are becoming increasingly popular for both commercial and recreational use.
