ROHM SEMICONDUCTOR 2022 7 Figure 4: Increased use of RFID tags will lead to better tracking of different assets. (Source: ROHM) ADVANCED TECHNOLOGIES USED IN IIOT Next, we will cover 3 leading technologies important for achieving smart logistics and smart factories. Robots Drones Smart Tags (RFID) Major online retailers have started to offer drone delivery services, such as medical supplies and food delivery. " " Figure 5: Robotics looks to play an increasingly prominent role in many industrial applications. (Source: ROHM) As smart tags become increasingly popular, consumers are more likely to see them in stores. They can also play an important role in smart factories and smart logistics (Figure 4). For example, attaching smart tags to products and reading them in bulk can lead to dramatically improved efficiency during delivery and inspection. Of course, this data can also be employed for asset management, making it possible to reduce the number of personnel and man-hours needed for management. Developing and using robots are essential for realizing IIoT. Advancements in sensing technologies, camera functionality, and AI have given rise to robots that can move autonomously in factories and facilities to perform operations. And robots are now being used for transporting and inspecting goods as well. Drones are attracting much attention as a way to revolutionize logistics in the future. According to research, the global market for drones is about 18 billion USD, including both private and military demand. This is expected to continue to increase, rising to an estimated 27.5 billion USD by 2025. The transportation and delivery services sectors in particular are projected to grow at a high CAGR (Compound Annual Growth Rate) of 29.7% from 2020 to 2025. The US, China, and several countries in Europe have already approved drone deliveries, primarily in suburbia. Major online retailers have started to offer drone delivery services, such as medical supplies and food delivery. Japan is currently conducting freight transportation experiments on remote islands, in depopulated urban areas, and even during disaster situations, which suggests that practical applications are likely to advance once regulations are relaxed.
