Home intelligent assistance mobile robot for the elderly

Abstract

With the continuous development of human economy and society, the continuous improvement of material civilization, and the continuous improvement of people’s living standards, the quality requirements for living households are also constantly improving. The use of machines to replace people to complete tasks such as cleaning and sanitation in the home, and to release people from the complicated housework has become the life concept of more and more people nowadays. At present, most of the home service robots are mainly disabled robots and housework robots such as sweeping robots. The functions are relatively simple. A family often needs to be equipped with multiple robots to meet people’s needs, and the cost is high. In addition, there are still many manual labors in the family that need to be done by people, such as carrying heavy objects, knocking nails, screwing screws, etc. Now that all work is becoming more intelligent and automated, people are eager to do these tasks by machines. In 2019, the “Joint Tips for Preventing Falls for the Elderly” jointly issued by seven institutions including the Chinese Society of Gerontology and Geriatrics, the Chronic Disease Center of the Chinese Center for Disease Control and Prevention, and the Beijing Institute of Geriatrics of the National Health Commission showed that falls are the most common cause of falls in my country. The number one cause of injury death among people over 65 years of age. Falls are a serious threat to the health of the elderly. The main cause of traumatic fractures in the elderly is falls. More than half of the elderly who visit medical institutions due to injuries each year are caused by falls. At the same time, the older the elderly, the higher the risk of injury or death from falls. Based on the above background, we designed this multi-purpose household auxiliary mobile robot. This robot has three forms, and is equipped with a handling robot arm and a blessing robot. Through deformation, the mechanical leg straightens and enters the standing state, which can help middle-aged and young people in the family to complete some physical tasks such as carrying heavy objects; when the mechanical leg is folded, the machine can be used as a movable chair to assist the elderly to move, and one-time handling More items; when the device is transformed into a car shape, it can help family members to move quickly.
