Number of Rotors
Single-Rotor Drones
Apart from multi-rotor drones like quadcopters, there are also single-rotor drones, commonly known as helicopters. Single-rotor drones feature a single large rotor on top and a smaller tail rotor for stability and control. These drones offer unique advantages such as longer flight times, higher payload capacity, and the ability to fly in more challenging conditions. Single-rotor drones are commonly used in military operations, transportation, and search and rescue missions where endurance and versatility are key.
Multi-Rotor Drones
Multi-rotor drones are the most prevalent type of drones available today, and quadcopters fall into this category. Multi-rotor drones are characterized by having multiple rotors, usually two or more, that provide lift and stability during flight. The number of rotors can vary depending on the specific design and purpose of the drone. Quadcopters, as discussed earlier, have four rotors, making them a popular choice for both recreational and professional use.
Quadcopters
Quadcopters have gained immense popularity due to their stability, maneuverability, and ease of use. The key advantage of quadcopters is their ability to adjust the speed and rotation of each rotor independently, allowing for precise control and stability during flight.
