【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 shoulder the significant responsibility of spraying chemicals and collecting agricultural information, making them a great help to 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.

Targeting agricultural plant protection machines and industrial inspection, Zoyi Technology integrates software and hardware to enter the international market

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.

Using AI vision to replace human vision, Claireye Intelligence uses AI to help the manufacturing industry with quality control

In response to customer demand on a wide variety of products in small quantities in the manufacturing industry, there is an urgent need to find AI solutions from the cloud to terminals Claireye Intelligence provides a solution that integrates software and hardware - BailAI image inspection solution to assist traditional manufacturing industries in improving process efficiency and product quality, thereby achieving the initial goal of transformation After the government declared 2017 to be Taiwan's "First Year of AI," AI startups have sprung up in Taiwan Established in 2018, Claireye Intelligence targets smart manufacturing and provides a platform for AI image analysis and process optimization, using the power of deep learning to detect product defects and abnormalities in the assembly process It assists companies in building infrastructure from terminals to the cloud, which enables automated monitoring of factory production to improve process efficiency and quality Focusing on AI image inspection based on its familiarity with the production line quality control process Shirley Liu, founder and CEO of Claireye Intelligence, is a young entrepreneur She entered the manufacturing industry after graduating from college and held a quality control position in the plastic injection process of hard disk parts "She was already on the production line at the time, and is familiar with the production line process of production machinery" She later switched career paths to marketing and planning, and then worked as an AI product manager When the time came, Shirley Liu decided to start a business, focusing on AI image recognition in the manufacturing industry "The difficulty for enterprises is the lack of an AI development team Even if an enterprise has an AI team, development projects will take a lot of time, at least 6-12 months" said Shirley Liu, who is well versed in the market's pain points The problem that needs to be solved by platforms is to provide services that allow traditional manufacturing industries to build their own AI models without needing employees with a programming background, and to remotely assist production lines with troubleshooting and subsequent system maintenance, helping companies save development time and labor costs BailAI image inspection platform usage scenarios Facing the large number of competitors that provide AI image recognition in the market, what are the technical advantages of Claireye Intelligence Shirley Liu said that many companies currently have AOI equipment, but the bottleneck in the application of AOI is that it can only be used for defect inspection in fast production of large quantities, and parameters need to be adjusted after each inspection or production Based on her understanding of the industry, most SMEs are limited by their financial resources due to AOI equipment often costing over NT1 million, but they also want to use automated inspection This is where Claireye Intelligence comes in Shirley Liu went on to say that it is impossible for traditional manufacturing industries to maintain a technical team that includes AI engineers, data engineers, cloud architects, and terminal architects Claireye Intelligence specializes in software and hardware integration Enterprises can use the BailAI image inspection platform to easily solve inspection problems on the production line In other words, customers only need to provide images or samples for Claireye Intelligence to carry out model training, model deployment, and system integration, and they can easily use AI technology to optimize and monitor production line processes Participated in the AI New Talent Selection and achieved a recognition rate of over 90 in assembly behavioral image recognition For example, a certain connector manufacturer only has 1-2 AI engineers in its technical team The main problem that needs to be solved is that most operators are on the production line, while quality control and senior managers are not on site, and the company wants to understand the actual situation of the production line through remote monitoring Claireye Intelligence uses industrial cameras to capture production line images, and transmits AI image analysis to the remote end Supervisors and quality control personnel can observe if there are any errors in the production line assembly, such as whether the connectors and lines are connected properly, through the monitor Claireye Intelligence's AI image inspection operates on Microsoft's Azure cloud platform, and also utilizes terminal equipment, such as NVIDIA's edge computing equipment placed around the inspection station, to assist traditional manufacturing industries with improving production line efficiency and detecting problems early through an integrated solution from the cloud to terminals Claireye Intelligencersquos customers currently include aviation, electronic peripherals, connectors, and metal industries Assembly process solution for human behavior recognition in assembly lines achieves an accuracy of over 90 In order to demonstrate the depth of technology, Claireye Intelligence participated in the 2021 AI New Talents Selection of the Industrial Development Bureau, Ministry of Economic Affairs, and provided Lite-On Technology with the "assembly process solution for human behavior recognition in assembly lines" The solution determines effective working hours and ineffective working hours of operators on the production line through cameras and AI image recognition It recognizes hand posture and position through images to determine the operator's assembly behavior, achieving an accuracy of over 90 Shirley Liu added that the assembly process of electronic components is complex, mostly carried out manually, and cannot be replaced by robotic arms Claireye Intelligence used cameras to film the assembly process of operators at Lite-On's assembly station The algorithm is then trained and corrected based on the video, and the final trained model can directly determine whether there are any errors in the assembly process to improve the overall process Project development time is expected to be shortened to 1 month by using the BailAI image inspection platform Since its establishment more than three years ago, Claireye Intelligence has accumulated a considerable amount of project experience and hopes to commercialize the project experience Shirley Liu pointed out that the trial version of BailAI image inspection will be completed this year 2022 Customers can choose industrial cameras or video cameras based on the detail of the object being inspected It can even use X-rays to capture images, and then the images are automatically marked by the platform Claireye Intelligence will provide customers with AI application models suitable for the field Inferences can also be made in the cloud or terminals for launch in the manufacturing industry The metals industry, metal casings of industrial computers, connectors, electronic peripherals, and mechanical parts can all use the platform for defect detection and object identification Claireye Intelligence will continue to improve its technical capabilities, accumulate customer experience to complete commercialization, and also accelerate the implementation of AI inspection applications In the mid-term, it will build terminal and cloud infrastructure and shorten the development time of enterprise AI projects from 6-12 months to 1 month, reducing usage time and lowering the threshold for enterprises The long-term goal is to target the Southeast Asian market where Taiwanese businesses are gathered, expand software and hardware integrated AI solutions to overseas markets, and expand the scale of operations

Defect identification rate reaches 100%, Nairi Technology is favored by major panel manufacturers

On the machine tool production line, there are some slight differences in the first step of assembly Accumulated tolerances will cause the assembly work to be repeated, which is time-consuming and labor-intensive, resulting in shipment delays that will impact the company's reputation Narili Technology Company focuses on the field of smart manufacturing and provides various AI solutions It uses machine learning models to inherit the experience of old masters In the CNC processing machine assembly and casting process, it uses AI to analyze production line data, accurately adjust various data, and improve Production accuracy is 25 This AI production line data analysis system is called "Master 40" by Huang Changding, chairman of Naruili Technology It is the most evolved version of the master plus artificial intelligence It has been used in machine tool processing factories with remarkable results In addition, Nairi Technology used AI defect detection technology to participate in the 2021 AI Rookie Selection Competition of the Industrial Bureau of the Ministry of Economic Affairs, assisting AUO in advanced panel image defect detection, with an accuracy rate of 100, and won the award Assisted panel manufacturer AUO to solve problems with 100 accuracy in defect detectionHuang Changding further explained that during the production of general panels, edges and corners are There may be defects in the corners Although the defects are visible to the naked eye, AOI is often difficult to identify, causing the detection error rate to often exceed 30 Therefore, re-inspection must be carried out with manpower to improve the accuracy rate However, in response to the demand for a small number of diverse products and insufficient manpower, using AI detection is indeed a good method Nairui Technology, founded in 2018, has been able to win the favor of major panel manufacturers with its AI technology in just three years In fact, it has been honed in the field of CNC machine tools for a long time Tang Guowei, general manager of Narili Technology, pointed out that the top three CNC machine tool factories in Taiwan hope to introduce AI into the two production lines of assembly and casting Among them, on the assembly line, in order to maintain the accuracy of assembly, every part of the component is designed Tolerances are designed During assembly, each component is within the tolerance However, the cumulative tolerance still fails the final quality inspection and must be dismantled and reassembled This is not only time-consuming and labor-intensive, but also causes waste "After entering the production line, I realized that some masters have accumulated a lot of experience and are good at adjustment After his adjustment, the accuracy rate has improved a lot and the speed is faster" On the contrary, the new engineers did not Based on experience, it takes a long time to adjust and may not pass the quality inspection The yield rate of Master 40 system has increased significantly from 70 to 95Tang Guowei then said that the original size data set by Master during assembly All were recorded on paper After the information was written, it was stored in the warehouse and sealed No one studied the relationship between the dimensions Narili assists customers in designing the Fu 40 system Through the human-machine panel, the master can directly input the measured dimensions and related data during assembly After collecting data from different masters, AI algorithms are used to analyze the relationship between the data and create an AI model The AI model automatically notifies the operator what size to adjust to, and the quality inspection will definitely pass In this way, the yield rate will be improved It has increased significantly from 70 to more than 95 Narili Technology Company focuses on the field of smart manufacturing and provides various AI solutionsTang Guowei added, assembling the spindle of a CNC processing machine It took four hours In the first step, the machine made measurement errors, including vibration, temperature, speed, etc that were out of range It had to be dismantled and reinstalled, which took another four hours How to adjust after disassembly depends on the experience of the master At first, the master may have done the best assembly method based on experience, but the error rate was also 30, and the assembly took several days With the assistance of AI masters, the assembly time only takes half a day, and the yield rate reaches over 95, saving a lot of time and manpower "Use the AI model of machine learning to collect the experience of all the masters and provide it for AI learning The first step is digitalization, and the second step is knowledgeization This is the transformation of the enterprise "An important key", Huang Changding believes that Narili Technology is an important partner in the transformation of traditional manufacturing from automated production to digital transformation In addition, another industry that Naili Technology focuses on is the smart car dispatching system of the leading brand of elevator manufacturers The so-called car dispatch referring to the elevator car means that if there are more than two elevators, group management is required In the past, car dispatching was based on fixed rules If the elevator was closer to the requested car, that elevator would be automatically dispatched On the one hand, it did not take into account that dispatching a car if the elevator was called too many times might make other people wait longer The previous vehicle dispatching model did not take into account the usage characteristics of the building, resulting in a lot of waste For example, in an office building, there are peak hours in the morning, lunch break, and afternoon after work AI smart car dispatch can be flexibly adjusted according to off-peak and peak hours, increasing the efficiency of car dispatch, reducing waiting time, and reducing wasted electricity Introducing elevator smart dispatch to improve transportation efficiency and have environmental protection functionsHuang Changding added that just like the previous traffic lights at intersections, the system has already The number of seconds to stop and pass on highways, sub-trunks and small streets is programmed Smart traffic lights are now used to flexibly adjust waiting times to make road sections prone to congestion smoother Using AI to learn usage scenarios and introducing a smart dispatch system into elevators will improve transportation efficiency and make it more environmentally friendly In addition to introducing smart elevator dispatching, Nairili also introduced AI into the smart production and shipment scheduling system of elevator factories Elevator factories often cannot accurately estimate the customer's elevator delivery date For example, office buildings or stores must be completed to a certain extent before the elevator can be installed on the construction site If affected by unexpected factors such as delays in the customer's construction period, the elevator factory will often be idle or the schedule will be difficult to arrange Tang Guowei pointed out that generally those who understand the progress of client projects may be from business or engineering, but overall, the accuracy rate of shipments is only about 60, which means that 40 of them will not be shipped as scheduled Therefore, if the shipping schedule can be accurately estimated, the production line can be freed up for emergency orders or other product production needs The AI smart scheduling system will analyze past shipment data, about 20-30 parameters such as climate, distance between the factory and the construction site, and customer credit, and put them into the AI algorithm to accurately predict whether shipments can be made as scheduled goods Huang Changding also specifically stated that the machine learning of Naili Technology is not ordinary machine learning, but also incorporates various calculation methods such as traditional image processing technology and statistics Only by being very familiar with the domain knowledge can we make good products AI models are also where the company’s competitiveness lies He emphasized that the data that general SaaS platforms can process is very limited, and the accuracy rate has increased from 70 to 75 at most Naili’s strength lies in AI algorithms and machine learning, and it must be coupled with in-depth industry knowledge to produce output Good AI model Narili Technology started with the AI project, gradually deepened the technology, chose to start with the more difficult tasks, and accumulated rules of thumb It is expected to develop SaaS services this year 2022, based on customer needs starting point, gradually gaining a foothold and becoming an important partner in smart manufacturing The picture left shows the general manager of Naruili
