Unmanned Aerial Vehicle or Drone is a kind of pilotless aircrafts getting command of wireless remote control. UAVs have a wide range of uses, low cost, good cost-effectiveness ratio, no risk of casualties, strong survivability, good maneuverability and ease of use. They play an extremely important role in modern warfare and have broad prospects in civilian fields.
As we all know, a drone can be working well only when the unmannedaerial vehicle system cooperates well. The drone system mainly includes the aircraft body, flight control system, data link system, launch recovery system, and power supply system. The flight control system, also known as the flight management and control system, is equivalent to the "heart" part of the UAV system, and has an important impact on the stability of the UAV, reliability of data transmission, accuracy, real-time performance, etc. It plays a decisive role in good flight performance.
Actually, the flight control system generally contains a lot of sensors, speed sensors, angular rate sensors, altitude sensors, pressure, optical flow, and so on. The drone is stabilized by sensors and PID adjustment, and the drone's attitude is changed by connecting the ESC to control the speed of the motor.
That is to say, we cannot attach too much significance to the sensor as the “Eye” of UAVs. So that is the point, my friends are adding a LiDAR onto the drone besides the camera to optimize the drone performance. Like the picture below.
Basically, we have a simple test to make it help hold the altitude and fly follow the topography. As the gif showing below. The LiDAR we use is from LiDAR TFmini, shown as the picture. Different LiDARs have different ways to connect drones, but thanks to the kind tech support, we got method to connect LiDAR with pixhawk.
