In the impression of many people, waterproofing an electronic object does not have any technical content. At best, it is "install a waterproof case." However, this is not the case. There are still many difficulties in making water resistant drones, and it is not easy to overcome these difficulties.
Difficulty 1: Motor
The design of the water-resistant drone motor is very sophisticated from the selection of the raw material of the motor to the post-processing. Since many drone enthusiasts in this field are also water sports enthusiasts, most of their activities are on the beach. Therefore, the motor must not only be waterproof, but also be corrosion-resistant. Water-resistant drone parts suppliers choose special materials to make motors, and use the linear electric adjustment specially designed for the debugging of waterproof brushless motor. Through the later processing, the waterproof brushless motor can be protected from fresh water and seawater corrosion from all details.
Difficulty 2: It is necessary to Make the Whole Machine Waterproof
In order to make the drone float on the water when it falls into the water, the material needs to be light. However, plastics and other materials are easily deformed materials, which are more difficult to use for waterproofing. The deformation of the pinhole size can cause water to enter the fuselage, so the structural design of the water-resistant drone needs to be very delicate.
Difficulty 3: Screw
In order to ensure the long-term waterproof performance of the water-resistant drone, each screw of the fuselage must use pure stainless-steel screws to prevent rust, and each screw must be individually waterproofed.
Difficulty 4: Barometer
Usually, the drone control system has an air pressure switch to determine the altitude of the aircraft through the ambient air pressure. Therefore, while realizing the waterproof condition, the drone must also communicate with the external air pressure, and be air-permeable and waterproof. It is not easy to solve this problem.
Difficulty 5: Flight control system
For the water-resistant drone control system, a customized closed source control system is also required.
