If we say that hardware is a hard nut to crack in the field of science and technology. In the drone industry, the rc flight controller
is a hard nut to crack in the drone industry. Currently, drone flight controller technology can be divided into two levels from easy to difficult: basic flight and environmental perception.
Basic flight, the so-called basic flight means the drone can complete the automatic flight of the scheduled flight through the remote control of the ground personnel, the route planning of the mobile terminal or the remote command on the basis of stable control. It is also the most basic stage of the flight controller system. However, what should we do when the drone is used in logistics, agriculture, patrol and other complex environments? Can buildings escape? Can you find the right place to land? How can the drone finish the corresponding tasks according to the characteristics of different industries?
Environmental awareness and environmental awareness refer to that drone should not only need to know their flight status but also know the external environment through sensors. Therefore, the flight control system needs the technology of sensor selection, digital filtering, multi-sensor data fusion, environment aware path planning and so on to make sure that the drone can complete the task at the same time in the complex environment. So where is the development of the flight control system at different levels of technology? How to overcome these difficulties? The maximum control characteristic of the vertical takeoff and landing multi-rotor drone is its unstable characteristics. It is similar to lifting a chopstick with our fingertips smoothly. We must balance the posture and position through constant adjustment.
