Some experts predict that by 2030, China's population over 60 will account for 20.42% of the total population. By 2050, the elderly population will reach 31. 2% of the total population. This also means that now 30 years old, as a social backbone. A group of people will be the "main force" of China's aging society in the future. An aging society, this is the challenge we will face and deal with; it is both necessary and important to explore the problems and solutions faced by an aging society. This edition will launch a series of reports on “Aging on Ageing†from today, and discuss how to deal with the problem of an aging society from the aspects of elderly products and medical care.
Due to the busy work of children and the inability to care for their elderly parents, the elderly care of the elderly has become a difficult social problem. In order to solve this problem, during the “Eleventh Five-Year Plan†period, the “National 863 Program†in the advanced manufacturing technology field listed “service robots†as a key project, and developed a number of cost-effective old disabled robot products. The purpose is to help the elderly with high technology. Andu is old.
User-friendly design meets the needs of the elderly
Professor Chen Diansheng from the Institute of Robotics, Beijing University of Aeronautics and Astronautics said: "Depending on the degree of difficulty in the elderly, we have designed different walking robots."
When the elderly with mobility problems are walking, they need to use human resources or equipment. Some robots can help the elderly to walk like a bodyguard. Some robots are wearable. The old man can "wear" the robot on the legs. It can drive the legs of the old man to exercise. There are also robots that can climb stairs. The old man can sit up and down the stairs. There is also a chair bed integrated robot designed for the elderly who stay in bed for a long time. Ordinary old people can use it as a bed. If you need to go to the bathroom or take things, The old man only needs simple operation control, and the robot becomes a movable wheelchair.
In general, dramatic changes in the vital signs of the elderly are often precursors to the disease. Some important physiological parameters of the elderly, such as pulse, body temperature, blood oxygen, etc., can now be transmitted to the robot for analysis through some portable detection devices. If the parameters are exceeded, the robot can wirelessly connect to the community network and transmit the data to the community medical center. In an emergency, you can call the police or inform your loved ones in time to gain valuable treatment time.
Because the elderly are generally lonely, it is also a direction to help the development of old robots. Some robots are very entertaining. In appearance, the robot uses a cute little panda image. With it, the old man is like a small pet.
Technical problems to be overcome
It is understood that at present, the service robot is still in its infancy, and there are still many technical bottlenecks in environmental modeling, autonomous control, human-computer interaction, and security.
Service robots must perform various tasks according to human instructions, and may have to travel in places such as homes and public places. This requires the robot to maintain sufficient flexibility. During the execution of the mission, the robot needs to correctly judge the obstacles. Obstacle avoidance, and the technology at this stage needs to be improved. On the other hand, the service robot must always be in contact with people. Its safety is very important. For example, when the robot gives the elderly tea, the robot must correctly judge the distance between it and the old man. Otherwise, it will be forced. Big, the cup hit the old man and it was troublesome.
In terms of human-computer interaction, robots can't reach the level of communication like humans, and can only respond to fixed words. The response to fixed words also depends on the environment. In a quiet situation, speech recognition can achieve a success rate of 890%.
Reducing costs is key
At present, Japan and the United States are at the world's leading level in service robot research. However, most of the robots they manufacture are used as exhibits, which are expensive and obviously exceed the spending power of ordinary Chinese people. Taking into account China's income level and consumption level, the 863 program "service robot" in the series of assisted and disabled robots strives for low cost and functional.
Minister Zheng Chunhui of the Mobile Service Robotics Department of the Xinsong Research Institute believes that the current price of the old robots on the market is higher because the more expensive sensors are needed to ensure the safety and reliability of the robots. If you have to have the appropriate medical facilities, the price may be even higher.
The old robot will be applied for demonstration next year.
Chen Diansheng introduced that at the end of next year, the series of assisted and disabled robots developed by the National 863 Program “Service Robots†will be applied in the concentrated application of the Four Seasons Township and the Shanghai Social Welfare Institute in Haidian District, Beijing. From the living room to the health center, from the infirmary to the monitoring center, there will be related helper service robot products put into use.
Xue Feng, dean of Shanghai No. 1 Social Welfare Institute, said: "At present, our manpower is mainly spent on basic nursing work for the elderly, and the ratio of nursing staff to the elderly has reached 1:1.5. If you can apply the assistant robot When you go to a welfare home, you can free the staff from the specific work and use the energy for the psychological comfort and communication of the elderly, so that the elderly can feel more social care."
"I hope that the robot is designed from the actual situation of the elderly, more humane, the operating procedures should not be too complicated, the shape should be cute, the sound should not be too blunt, and the old people can feel the communication between people." Liu Zhongli, dean of the nursing home, said.
Experts pointed out that through the exhibition demonstration, it is possible to attract relevant enterprises to visit and learn and guide the industrialization of the old robot products. If mass production can be achieved, the price can be lowered, and it is not far off for robots to enter the family or social care institutions.
Today's robots are just like the computers of 30 years ago. They are in the early stage of industrialization. If they can achieve modularization and standardization, each organization will perform its own functions, specialize in a certain part of the robot, and then integrate different products according to the requirements. This will help promote the industrialization of robots. Shanghai Medical Device Industry Association
Foot Warmer is also named as Heating Boot, as it looks like a boot in the shape.
It has a fashionable design, hence it is also a good choice as a promotional gift.
In the cold winter, foot warmer is a best choice for keeping warm. When the feet are warm, the entire human body warms up quickly.
It also has a controller with adjustable heat settings, as well as the auto shut off function.
