Using Spray Drones To Fight COVID-19

COVID-19, otherwise known as the Coronavirus or 2019-nCov, has rapidly expanded around the globe, and health officials and researchers are working hard to understand and prevent the pandemic from spreading further. In order to slow the spread of the infection, many countries have taken tough containment measures, such as instilling stay-at-home or shelter-in-place orders.
Some have even used UAVs to combat the pandemic: Spain, for instance, was the first European country to implement an agricultural drone to spray disinfectant in large, public areas.  More recently, French company Flying Eye also used a DJI drone to do the same especially in urban spaces.
In this article, we will cover what operating personnel should pay attention to when they disinfect public areas around them.

For Operating Personnel

WHO (World Health Organization) says that COVID-19 can spread from people who already have the virus, and it “spreads primarily from person to person through small droplets from the nose or mouth, which are expelled when a person with COVID-19 coughs, sneezes, or speaks.”  To minimize contact with others, personnel should keep at least 1 meter, or 3 feet, from each other.
While disinfecting, avoid smoking, eating, or drinking of any kind.
Personnel should protect themselves by wearing disposable clothing, such as caps and gloves.  Overalls, protective goggles, work shoes, rubber or waterproof boots are recommended as well.
Personnel should wear masks while on duty. WHO also says that wearing a mask “can limit the spread of certain respiratory viral diseases, including COVID-19.” If the mask is deformed, wet or dirty in any way, it should be replaced with another one.

The Flight Area

Permission from local governmental departments should be obtained in advance so as not to violate the regulations in place.
Since disinfectants have a certain corrosiveness, clear the space that will be disinfected and move all people and animals to avoid accidents.  Food and clothing that is not being worn should be put away in advance as well.
To minimize repeated spraying and leakage, plan out the flight area and path in advance.
During the flight, the pilot should always pay attention to any obstacles, keep the flight interval with obstacles at all times, and ensure the safety of flight equipment and property.

Maintenance

After spraying, it is necessary to clean the aircraft and the spraying system because the residual disinfectant can corrode the aircraft, metal structure, water pumps, sprinkler heads, and pipelines, which will affect the service life. Moreover, if the water pump or sprinkler head is blocked, the spray flow will not work quite as efficiently the next time it is used.
About the maintenance of drone batteries, ensure that the voltage difference is less than 0.2V, and charge the battery with a small current to balance the voltage difference. Do not discharge the battery if the voltage is abnormal. The battery should maintain about 3.85V when put into storage, and keep a regular charge-discharge maintenance every month or at least every three months.
