AI-based drones help analyze health of crops

2020/11/04


The drones using artificial intelligence (AI) technology developed by MiSmart are all unmanned aerial vehicles (UAV) manufactured locally by Vietnamese.

 

The UAVs conduct aerial reconnaissance to find insect-infected areas. They also spray chemicals on the infected parts of crops, thus saving up to 99 percent of pesticides.

MiSmart won first prize at Viet Solution, an international competition seeking digital transformation solutions initiated by the Ministry of Information and Communications.

 

The drones from MiSmart are the achievements of a group of young developers headed by Pham Thanh Toan, CEO (chief executive officer) of MiSmart, and his co-worker Tran Phi Vu, who is now CTO (chief technology officer) of the project.

 

Toan and Vu were friends at high school, but did not keep contact until they accidentally met again on Tet holiday. At that moment, Vu was a PhD student studying UAV at New South Wales University in Australia. Toan had for many years been developing machine learning software and AI.

 

They decided to set up MiSmart, a project making specialized drones for different purposes.

 

After two years of implementation, MiSmart’s two drone models, Mis GA-22 and Mis TH-16, were first commercialized six months ago.

 

Farmers use the drones in an automatic, semi-automatic or manual mode. The devices are designed to be resistant to dust and water. They can also be folded after use.

 

MiSmart’s drones have a common characteristic in that they are made of carbon fiber, lighter than aluminum, but are 5 times firmer than titanium, capable of lifting heavy objects weighing up to 22 kilograms.

 

This is one of the rare drone models made fully by Vietnamese, from its hardware to its software design.

 

Toan said MiSmart makes drones used in agricultural production to help increase the value of Vietnam’s farm produce. The drones can help find insect-infected areas, thus reducing pesticide abuse and minimizing costs.

 

MiSmart’s drones go ‘scouting’ by sending maps to the server and discovering insects thanks to AI and spray chemicals. All of these metrics are on an IoT platform for management. Farmers can know the exact areas that need chemicals spraying, and there is no need to conduct many drone operations.

 

The drones are programmed to support the spraying of plant protection chemicals over large farmland areas, and they can move up or down or navigate in accordance with terrain conditions.

 

MisMart doesn’t use AI cameras. Instead, it uses low-cost high-resolution cameras. After drones take pictures and send images to the server, the images are analyzed by AI to find the abnormal points. Drones continue to fly to those points to capture more images and identify insect areas. These are the outstanding features provided by AI technology which the naked eye cannot discover.

 

If compared with traditional spraying methods, MiSmart’s drones operate 40 times more effectively thanks to radar. The radar scans the land area below and maintains reasonable spray distance, thus saving on chemical use.

 

Digital transformation in agriculture

 

After six months of commercialization, Toan’s company has revenue of VND4 billion. MiSmart’s business includes drone sales and leasing.

 

A drone device from MiSmart sells for VND200-250 million.

 

MiSmart’s products became better known after good feedback from customers.

 

MiSmart also plans to use technology in forest management, mapping and rescue activities.

 

MiSmart’s major clients are not farmers, but agriculture co-operatives, spraying companies and large agriculture production corporations. These clients have certain knowledge and thus it is easier to transfer technology.

 

According to Toan, each area has its own terrain characteristics, so drones are designed depending on the area so they can operate most effectively.

 

Currently, MiSmart is targeting the Mekong Delta market, where there are large sample fields. In the north, MiSmart is targeting tea fields. It plans to develop a drone model specifically used for coffee fields in the Central Highlands.

 

According to Toan, the biggest difficulty in manufacturing drones is weak supporting industries. MiSmart can manufacture mechanical parts and develop software, but it still has to import motors and batteries.

 

Flying permits are also a big problem. Not all clients of MiSmart can get a license, which is an obstacle for its products to reach the market.
