It has long been clear that the DJI Mavic 2 drone is one of the safest and most reliable drones in the world. The model has the latest TapFly autopilot, which allows you to create routes with a flick of the wrist. If there is any obstacle in front of the quadcopter, the device will simply fly around it and continue to fly along a given trajectory. The shooting angle when flying over an obstacle will be saved. Today we will talk more about the DJI Mavic 2 unmanned aerial vehicle.
The drone has a camera on a hydroscopic suspension, but it is far from the only one. There is also one camera on each side of the quadcopter, as well as two in the nose, tail and bottom. Such a large number of cameras allows you to determine as accurately as possible how much is left before the obstacle. The detection accuracy can be up to centimeters. The central processor of the drone processes the received information in moments, which allows you to quickly determine the most appropriate route.
The greatest danger to an unmanned aerial vehicle is presented by obstacles from above and below, because such obstacles are not always visible through the main camera. To detect such obstacles, special IR sensors are used that can detect an object at a distance of up to 11 meters. There is also an auxiliary system in the form of a bottom light, which is especially useful if the flight is carried out in poor light, i.e. twilight or in the shade of tall buildings.
While the Mavic 2 has impressive specs, it’s not all-powerful. For example, the collision avoidance system is only capable of operating at speeds up to 50 km per hour in forward movement and up to 42 km per hour in reverse. There are also “dead zones” for sensors located in the diagonal planes of the quadcopter. If you want the drone to develop maximum speed, then it is better to practice well before that.
It is worth noting that the shape and size of the obstacle are very important. Drone sensors can easily recognize tree poles and trunks, but leaves and wires can be difficult to recognize. If you decide to operate drones in the forest or near power lines, then you should exercise extra caution.
Movies have taught us that a human can fool a robot by improvising. For you to understand, we will give an example. Let’s compare how a drone behaves near a snow-white glossy wall of a house or a matte black car. If we talk about the first option, then the level of light reflection is very high, and in the second situation it is very low. And the danger can come from mother nature. The threat may be the smooth surface of a lake, a turbulent river, or a snow-covered plain.
The weather can also cause a lot of trouble for the owner of a quadrocopter. The fact is that at high humidity, water drops can condense on the camera lenses, which, as you understand, seriously limits the view. And fog is a big danger. It is worth familiarizing yourself with the weather before you go to launch an unmanned aerial vehicle.
Now let’s talk a little about flight conditions. The obstacle detection system works best at a height of 2–11 meters above the ground. If the copter is below 2 meters, then the system is able to “skip” individual irregularities, especially at high speeds. If the drone is higher than 11 meters above the ground, then the IR sensors will simply lose contact with the surface.
How to deal with it?
Of course, it may seem that the Mavic 2 drone is easily “lost” in any situation, but this is absolutely not the case. For starters, rain and fog do not happen that often, and flying in such weather is prohibited by the instructions. And perfectly black and white surfaces are not so common in real life. In addition, the safety and stabilization systems are not turned off completely — they become less effective. Even then, you can fly the drone smoothly and land gently on the ground.
If you pay attention to the instructions, then it says that you should be extremely careful in such a situation. Do not turn on the sport mode, do not make sharp dangerous maneuvers near obstacles and carefully climb. This applies not only to beginners, but also to experienced owners of unmanned aerial vehicles.
Do not forget that the device needs to be properly looked after. Camera lenses, lights, and IR sensors should be checked regularly before flying the aircraft. They must be free of dust, dirt or water. You can wipe all these surfaces with a soft cloth, such as microfiber. Never use harsh chemicals when cleaning parts of the quadcopter.
If the unmanned aerial vehicle suddenly encounters an obstacle, then you will need to re-calibrate the device. Use the DJI Assistant 2 app. To configure the sensors, you need to raise the quadcopter in the air and point the camera of your smartphone at it. Then level the machine and fix it in this position. This action must be done for all review systems. If it so happened that the sensors are damaged, then you need to turn off the drone, and then repair it. Restoration of an unmanned aerial vehicle should be trusted by experienced professionals from DJI.
The security system is very important for a quadcopter. It will allow your device to avoid a lot of trouble. Naturally, the possibilities of this system are not unlimited. Always operate the drone with care and follow the instructions.
