【2021 Solutions】 Drone expert Droxo Tech uses its Strengths to Become a Pioneer in Epidemic Prevention
In May 2021, at the Tai'an Elementary School campus in Taichung City, two drones quickly took off and sprayed disinfectant in the campus of Taian Elementary School in Taichung City, completing emergency disinfection of the entire campus in a single day. The company using drone technology for epidemic prevention is none other than the Tainan-based Droxo Tech, which has been silently carrying out this technology-based epidemic prevention work for more than six months.
In fact, Droxo Tech was established in 2018. Members of the team are aerospace technology engineering experts. Cheng-Han Hsieh, president of Droxo Tech, who was also a member of the Taiwan team in the 20th APICTA AWARS, said that Droxo Tech mainly develops drone technologies and applications, and is committed to using drones as vehicles to break through the existing technical framework. In agriculture and industrial inspection, the company uses highly efficient customized drones to break through existing work patterns and solve problems, such as labor shortage and work hazards in industries.

The global commercial drone market is expected to grow to US$8.7 billion in 2025
According to statistics of Fuji Chimera Research Institute, as the unit price of drones decreases, drones will gradually become more popular, extending from their initial aerial photography function for general consumers to commercial products for agriculture, measurement, and logistics. In terms of drone market size, global drone shipments was 3.9 million units in 2019, and are estimated to reach 4.18 million units in 2020.
A report published by Global Information, Inc. (GII) also pointed out that commercial drone services, such as: photography, entertainment, surveying and aerial operations, disaster survey and relief, early warning systems, data collection and analysis, and environmental monitoring, have considerable profit opportunities, which are predicted to grow to US$8.7 billion per year in 2025. Droxo Tech targets agricultural drones and industrial surveying in the commercial drone market. Agricultural drones replace manual pesticide spraying and fertilization, and only needs six minutes to spray approximately 4,850 m2 of land, reducing pesticide use by 50% while achieving a control effect reaching 95%.
In addition, drones use AI spectrum NDVI image recognition technology to identify the growth status of crops, such as rice paddies, and establish an agricultural information system. Industrial inspection drones are for offshore wind turbines, bridges, etc., recording 360-degree images without blind spots for big data analysis in the cloud.
▲Agricultural drones are responsible for spraying pesticides and collecting agricultural information, making them a good helper for farmers.
Cheng-Han Hsieh said that based on the global market observations, using agricultural drones to spray pesticides is a basic need, but the back-end agricultural information analysis is the indicator that is truly important. If a data platform can be established, it will greatly benefit agricultural development and pest control. In addition, the use of agricultural images combined with multispectral images and analysis of rice paddy soil and fertilizer content has produced concrete results in rice growth monitoring. Based on empirical results of rice paddies in Meinong, Kaohsiung, the amount of pesticides sprayed by traditional farmers was double the standard. Data analysis let farmers understand that they do not need to spray too much pesticide and it will not affect the quality and harvest.
The specific method is to record plant growth indicators and import them into the back-end system in coordination with the analysis. Whether plants have pests or diseases is determined through back-end big data processing and analysis, monitoring of plant growth, and analysis of infrared images, and different amounts of pesticide are sprayed based on the data. "In the past, farmers relied on the weather for their livelihood, but now they let the data speak for itself." Cheng-Han Hsieh believes that helping farmers accurately monitor the growth of crops and make correct decisions is the most important contribution of drones in collecting agricultural information for analysis.

In terms of industrial surveying, traditional industrial inspection has three disadvantages: 1. Manual operations is dangerous;2. The manual inspection takes too long;3. Lack of third-party verification tools. Drones overcome the three major disadvantages above. Droxo Tech uses drones for bridge and wind turbine inspection. First of all, in terms of bridges, traditional inspection requires hanging and inspection time is too long, manual operations are dangerous due to the strong winds. Drones can take off at any time for inspection, and 3D models can be created using 3D image recognition, so that rust and cracks have nowhere to hide.

The inspection of offshore wind turbines also faces risks such as climbing and hanging of manual operations and strong winds. Using drones to replace engineers for inspection work is safe, effective, and convenient.
Droxo Tech focuses on drone technology. Cheng-Han Hsieh said that the short-term goal is still to focus on agricultural drones, supplemented by collecting agricultural information for big data analysis, in order to provide more complete agricultural information to agricultural units as the basis for agricultural reform.The mid-term goal is to continue to improve the flight control system, strengthen the application of the control system in the field, such as automatic landing, automatic tracking, and activate mission scheduling.The long-term goal is to become an automation company specializing in the design of automated vehicles or automated monitoring equipment.
For example, drones used to spray pesticides are currently used in large outdoor areas, but greenhouses also have great demand. Greenhouses with a planting area of 4,850 m2 also need to spray pesticides and harvest. Since greenhouses are indoors, there is more interference with the drone navigation system. After the control system is strengthened, automated guided vehicles (AGV) or automated design will be introduced indoors or in greenhouses, and the vehicle will be changed from drones to AGVs to solve the troubles of farmers.
Since Taiwan's agricultural drone market has a limited appetite, about 200 units per year, Droxo Tech also plans to develop overseas markets, initially selecting Southeast Asia and South America. Palm trees in Malaysia are crops with high economic value, a large planting area, and have greater opportunity to use agricultural drones. At the same time, in order to help improve the planting environment, Droxo Tech will also establish an agricultural information recording platform and export equipment and systems integrating software and hardware to overseas markets.
