Multirotor drones are types of drones that include multiple motors that work together to lift the drone vertically. The main difference between them compared to fixed wing drones is that they do not have a wing for flying. This makes multi rotors dynamically unstable and require a control system for stabilization during flight, which is done with the help of an onboard inertial measurement unit (IMU), to control the attitude of the drone.

On the other hand, fixed wing drones can glide using their wings, which gives them higher speed while less energy is consumed.

Moreover, they can move in all directions without rotating the whole frame, which is in contrast to fixed-wing drones. This means that multirotors need to know the direction that they are facing, which necessitates the use of a compass sensor for autonomous missions, while fixed-wing drones can find the direction based on the direction of movement using a GPS sensor. Some multirotor drones have a foldable arm design, which makes them compact to easily fit inside a small package for transportation.
