An overview of transfer nursing robot: Classification, key technology, and trend

The transfer nursing robot plays a vital role in facilitating the movement of elderly individuals or patients who are unable to walk, aiding in transfers between beds, wheelchairs, and operating tables, among others. Given the current societal challenges posed by an aging population and a shortage of caregivers, transfer nursing robots have gained significant attention. This paper provides a comprehensive overview of transfer nursing robots, categorizing them into six distinct types based on their working methods. Each type’s working principles and characteristics are described in detail. The transfer nursing robot is a complex integrated system, requiring analysis of key technologies. This paper investigates the application of these technologies in transfer robots and specific types, including structural design, human body force analysis, machine perception, control strategies, human–robot interaction, and comfort considerations. Additionally, it discusses current limitations in the field and identifies future trends for transfer nursing robots.
