Application advantages and development status of emerging nursing robots

(3) Japan's nursing robots: Japan is known as the "kingdom of robots" reputation, entertainment robots, guide robots, cleaning robots and other robots widely participate in all aspects of people's lives. Compared with other countries, Japan's nursing robots have large output, multiple functions and a wide range of applications. Japan has made it a national policy to promote the development of household robots, and has formulated a "technical strategic blueprint" to plan the development of robots.

Since the introduction of robots and technology from the United States in the 1960s in Japan, after the development of the 1970s and 1980s, the aging trend in Japan is obvious, and the Japanese government began to attach great importance to the research and development of nursing robots. The "National Technology Strategic Plan" issued by the Japanese Ministry of Economy, Trade and Industry predicts that care robots will gradually enter the life of ordinary families. In addition to the government's attention, a large number of manufacturing research and development companies in Japan have developed nursing robots, established automated production lines of robots, and become integrated suppliers of logistics and warehousing automation equipment. The Japan Robotics Association estimates that Japan's domestic robot market share will reach 931 billion yen in 2025, mainly in the medical care and welfare services sector. The association hopes that when the problem of aging society becomes serious, smart devices can serve the elderly.

In 2005, in order to provide living support for the elderly, a Japanese company developed two household robots, "companion" and "recognition". With multiple built-in microphones and advanced image and voice recognition technology, the two robots can understand user commands and automatically follow users.

(4) Nursing robots in South Korea: South Korea has high independent intellectual property rights of robot technology and launched a national strategic development of robots, service robots as a development focus. South Korea has given key support to service robot technology, and has identified intelligent service robots as one of the nine new growth engines to promote national economic growth in the 21st century, and strives to make it a new economic growth point. Research on the design and development of service robots and set off the trend of developing service robots in Korea. Android robot, a humanoid robot developed by South Korean scientists, has real-time data transmission, sound and image power sensors, high-speed processors and other technologies, with ranging, voice recognition, processing command signals and interaction with the surrounding environment and other functions.

3.2 Development status of nursing robots in China

In recent years, with the support of the "863" program, China has carried out a lot of work on the research and development of service robots and made some achievements. In addition to state support, various enterprises and universities have set up research teams, and the research results of robots in various fields have gradually become fruitful. At present, the service robots developed in China mainly include medical robots, cleaning robots, entertainment robots and so on. For example, the robot team of the University of Science and Technology of China "Kejia" can cook food for people, and the intelligent service robot developed by the Harbin Institute of Technology can pour water for patients, feed medicine, communicate with patients simply, sing and dance.

In November 2010, the first personal hygiene care robot in China was successfully developed. This nursing robot mainly uses intelligent control based on fuzzy theory, ergonomics and other technologies to provide a full set of bathing services for the elderly and disabled people with mobility difficulties.

In 2008, a university in Taiwan developed "ROLA," an intelligent robot for home care. ROLA has voice recognition and conversation ability, can recognize faces and locate the user's location, and always accompany the user. The robot can recognize the indoor environment and has the function of avoiding obstacles. In addition, the development team is studying the robot's support function, so that elderly people can walk with the robot according to their own will.

In March 2011, a robot laboratory in Shanghai developed the "Jiaolong" robot. The "Cross dragon" robot is suitable for the elderly and welfare homes with no one to take care of it. The whole body is white, and there is an operable electronic display in front of the body, which has the functions of reminding the elderly to take medicine, take medicine and bring water. It can not only serve the elderly, but also serve as a welcome and tour guide for shopping malls and exhibition halls.

In addition to these, the National Rehabilitation AIDS Research Center has also taken the lead in the development of many cutting-edge domestic products, such as orthopedic prosthetics, three-position intelligent wheelchairs and service robots. At present, although our country has made progress in the development of service robot, there is still a gap with the developed countries.
