In recent years, the application fields and forms of robots have developed quite rapidly, from families, restaurants, to shopping centers, hotels, to warehousing logistics, industrial equipment manufacturing, almost everywhere. It is particularly noteworthy that in recent years, robots are gradually transforming from automation to intelligence and autonomy, and intelligent robots with self-learning ability are subverting human's traditional cognition of robots.
According to the White Paper on the Technology Industry Development of the Intelligent Robot Industry (2023 edition), the global intelligent robot market will exceed $50 billion in 2022 and will exceed $66 billion in 2024. Among them, with the deepening of China's industrial digital transformation, China's intelligent robot market is expected to reach $25.1 billion in 2024, with a CAGR of 20%. Industrial robots, service robots, and special robots will account for 50%, 35%, and 24% of the global total.
As early as 2017, the China Academy of Information and Communications Technology, IDC International Data Group and Intel jointly released the white paper "Robot 3.0 New Ecology in the Era of Artificial Intelligence". In the book, the development of robots is divided into three eras: robot 1.0, robot 2.0, and robot 3.0. The description of robots also changes from "they have no sense of the external environment, and can only reproduce the teaching actions of humans, and replace workers in the field of manufacturing by mechanical repetitive manual labor." Gradually evolve into "in addition to the perception ability to achieve intelligent collaboration, but also have the ability to understand and make decisions, to achieve autonomous services." And "90, even 95 percent of the time, you can do the task autonomously."
This is a multi-stage rocket development model similar to the Internet, the first stage - key scenarios, grasp the vertical application, improve the matching of scenarios, tasks, capabilities, improve the ability of robots in key application scenarios, expand the user base; The second stage - artificial enhancement, by adding the ability of continuous learning and scene adaptation, extending the service ability, replacing part of the human, gradually realizing the replacement of human, so that the ability of the robot can meet the user's expectations; The third stage - scale, through the cloud-edge-end integration of the robot system and architecture, so that the robot to reach millions of millions of levels, so as to reduce the price cost, to achieve large-scale commercial.
According to the Chinese GB/T 39405 2020 standard, the current robot can be divided into three categories: industrial robot, service robot and special robot. Among them, service robots have complex application scenarios, close interaction with people, and huge market potential, and are the most urgent for intelligent upgrading. Data show that in 2023, China's service robot market size reached about 60.016 billion yuan, with a compound annual growth rate of 32.41% in the past five years. The global robot market is expected to grow nearly tenfold over the next 10 years, reaching $160 billion to $260 billion by 2030.
In many subdivisions, the sweeping robot is currently the most widely used and the largest sales of service robots.
The "2024-2029 China sweeping robot industry market Prospect forecast and future development trend Research Report" released by the China Business Industry Research Institute shows that from 2019 to 2020 is the stage of rapid development of sweeping robots, with retail sales of more than 6 million units, and the retail sales of sweeping robots have declined in the following two years. Sales of sweeping robots rebounded in 2023, with retail sales of 4.58 million units, an increase of 4%. From January to April 2024, the retail volume of sweeping robots was 1.02 million units, an increase of 17%. China Business Industry Research Institute analysts predict that China's retail sales of sweeping robots will reach 5.25 million units in 2024.
