Multirotor drones typically consist of four, six, or eight rotors, each driven by an electric motor.

A multirotor UAV is a drone that consists of multiple rotors, usually four, six or eight rotors, each driven by an electric motor. Multirotor UAVs have vertical take-off and landing and hovering capabilities, and can fly flexibly in a small space, so they are widely used in aerial photography, search and rescue, agriculture, security and other fields.

One of the advantages of multirotor UAVs is their stability and hovering ability. Because of the multiple rotors, the drone can maintain balance and stable flight by adjusting the speed of each rotor. This makes multirotor UAVs very suitable for high-altitude aerial photography and taking detailed pictures, because they can be fixed in the air without shaking or deviating from the direction.

Another advantage is the flexibility and maneuverability of multirotor UAVs. Due to the design of the rotors, multirotor UAVs can fly and hover freely in a small space, and can perform various complex flight tasks, such as crossing obstacles and circling buildings. This makes multirotor UAVs an ideal choice for search and rescue and emergency rescue.

In addition, multirotor UAVs are also easy to operate and maintain. Due to their simple structure and design, multirotor UAVs are usually easy to use and simple to operate. At the same time, it is relatively easy to maintain and replace parts, which greatly reduces the cost of use and maintenance.

Multi-rotor drones also have some challenges and limitations. First, the endurance of multi-rotor drones is limited, and they usually need to return to charge after hovering or flying in the air for a period of time. This limits the scope and time of use of drones. Secondly, multi-rotor drones have a small carrying capacity and cannot carry large equipment or items, which limits their application in certain fields.

Multi-rotor drones are a powerful and versatile drone system with advantages such as stability, flexibility and easy operation. They are widely used in aerial photography, search and rescue, agriculture, security and other fields. With the continuous advancement of technology, multi-rotor drones will play a more important role in the future and continue to expand their application areas.
