Description

Technical Field

[0001] The present invention relates to the technical field of companion robots, and in particular to a companion robot for hospitalized elderly people. Background Art

[0002] In the current market environment, companion robots are gradually gaining widespread attention as an innovative solution to cope with an aging society. With the advancement of technology and the improvement of the quality of life requirements of the elderly, the types and functions of companion robots are constantly enriched, forming a diversified product ecosystem. Companion robots can be roughly divided into several categories: Emotional companion robots, such as Paro (seal robot) and Aibo (Sony robot dog), mainly provide emotional support through cute appearance and natural behavior patterns. These products focus on emotional interaction with users to help the elderly reduce loneliness. Although their functions are relatively simple, they play a positive role in meeting the emotional needs of the elderly. Health monitoring robots, such as ElliQ and Robear, combine health monitoring functions to collect and analyze the health data of the elderly in real time. This type of robot not only provides health advice, but also reminds the elderly to take medicine on time or do appropriate exercises to help them better manage their health. This type of product is especially favored by family caregivers because it can effectively reduce the burden of care. Multifunctional intelligent robots, such as Buddy and Leka, integrate multiple functions such as emotional companionship, health monitoring, entertainment and social interaction, and can interact with users in a rich way. These robots can not only play music and videos, but also connect through social media to enhance the connection between the elderly and their families and promote social interaction. Service robots, such as Care-O-bot and Pepper, are mainly used to provide services and support, including information query, smart home control and emergency calls. These products interact with users through voice and have certain emotional communication capabilities, but their core functions still focus on service.

[0003] Although the companion robot market has broad prospects, it still faces some challenges. The single function cannot take into account both health monitoring and companionship; users may encounter complex operation interfaces during use, especially for the elderly, and the difficulty of learning to use may limit the popularity of the product. There are too many elderly inpatients in hospitals who need urgent care, which makes it inconvenient for medical staff to manage, and companion robots cannot take care of multiple elderly people.
