Multirotor drones are primarily unmanned aerial vehicles (UAVs) which make use of multiple rotors for achieving flight and tactical maneuvering. Traditional drones with single or double rotors make use of variable pitch rotors to achieve flight stability and control. Due to the requirement of movable or adjustable rotors, traditional drones are complex in design and costly to manufacture. Multirotor drones make use of numerous fixed rotors and achieve flight control through variable relative speeds of different rotors. Thereby, multirotor drones offer simplicity in design and ease of use in various short physical range applications. Owing its compact size and ease of control, multirotor drones have witnessed immense popularity in commercial, government and personal applications. In addition to its ease of accessibility to remote places, these drones can serve various other functions by carrying various payloads. With an integrated camera, these drones can be used for image capturing and video recording at inaccessible, remote or hazardous places. Thereby, multirotor drones have found numerous applications including surveillance, traffic monitoring, and physical location monitoring. Furthermore, with the use of various sensors, multirotor drones have witnessed immense applications in the field of chemicals, nuclear and radioactive materials. Thereby, multirotor drones are widely adopted in various end-use industries including government and defense, chemicals, environmental research, infrastructure and construction, and media and entertainment.
