What is a Quadcopter Drone, and how does a quadcopter work?

A quadcopter is a multirotor drone with four arms or booms, each with a rotor (hence “quad copter”). Multirotor drones are unmanned aerial vehicles (UAVs) with multiple rotors that are used to generate lift to enable the aircraft to fly. The working principle of a quadcopter drone is that one pair of rotors turns clockwise and the other anti-clockwise, and by varying the speeds it is possible to generate thrust as well as turning motions.

Quadcopters are VTOL drones, meaning they are capable of vertical take-off and landing (“VTOL”). This is ideal for situations where launch space is restricted, for example if the quadcopter is required to launch and land on a vessel at sea. The ability to hover in place gives quadcopters an advantage over fixed-wing drones and aircraft for small-scale surveillance and reconnaissance.

Many quadcopter drones are gyro-stabilised to allow them to fly smoothly even in windy conditions. An IMU (inertial measurement unit) detects changes in the yaw, pitch and roll of the drone and sends data to a flight controller, which adjusts the output to the quad rotors to achieve the desired outcome.

Quadcopter Applications

Quadcopters are simpler in construction and cheaper and easier to fly than unmanned helicopter drones, making them an ideal choice for certain applications such as surveying and aerial photography. They can also be used for drone deliveries and have already been used to provide medical supplies in both remote and urban areas.

Quadcopter drones are used in a wide range of professional applications, with the drone and payload specifically chosen to suit the application type. Industrial quadcopters are used in applications such as pipeline and infrastructure inspection; agricultural quadcopter drones can be used for crop monitoring; and survey-grade quadcopters with high-resolution cameras and/or LiDAR technology can be used for mapping, surveillance and surveying applications.

Size and Endurance of Quadcopter Drones

Quadcopter sizes range from mini quadcopters which are not much more than an inch square, to professional drone systems measuring two to three feet in diameter. There tends to be an upper limit on the size of quadcopter frames as more volume means more weight, which requires more power to lift – there is then a trade-off between battery weight and size versus flight endurance.

The typical flight time of a battery-powered quadcopter is around 30 minutes. New designs have managed to extend this by incorporating battery cells into a majority of the quadcopter structure. Hydrogen fuel cells, providing a greater energy density than batteries, can also be affixed to larger quadcopters to extend flight endurance.

Quadcopter Cameras and Aerial Imaging

Aerial imaging is the most popular application for quadcopter UAVs, and many quadcopter manufacturers offer packages pairing a quadcopter with a specific camera payload. These cameras may be integrated into multi-axis gimbals that allow the camera to be moved during flight and also reduce the effects of vibration.

Video and still image camera payloads can offer powerful optical and digital zoom capabilities to professional-grade quadcopter drones, with 4K video and still image resolutions in the tens of megapixels, making them ideal for tactical and professional applications such as surveillance and industrial inspection. Some quadcopter cameras also offer FPV (First Person View) capabilities, in which low-latency video is fed back to the pilot via 4G/LTE to a screen or headset. FPV quadcopter drones are often used in the sport of drone racing.

Many quadcopter imaging systems feature a range of intelligent flight modes to enhance functionality, such as following the operator, active target tracking, and autonomous following of waypoints.
