As an important branch of medical robot, rehabilitation robot has become a research hotspot in the field of international robot because its research runs through many fields such as rehabilitation medicine, biomechanics, mechanics, mechanics, electronics, materials science, computer science and robotics. Rehabilitation robots have been widely applied in rehabilitation nursing, prosthetics, and rehabilitation treatment, which not only promotes the development of rehabilitation medicine, but also drives the development of new technologies and theories in related fields.

 
Rehabilitation robots are a combination of industrial robots and medical robots. The 1980s was the initial stage of research on rehabilitation robots, with the United States, the United Kingdom, and Canada leading the world in research on rehabilitation robots. Before 1990, 56 research centers worldwide were located in five industrial zones: North America, the Commonwealth, Canada, the European continent, Scandinavia, and Japan. After 1990, the research on rehabilitation robots entered a period of comprehensive development. The research on rehabilitation robots mainly focuses on rehabilitation robots, hospital robot systems, intelligent wheelchairs, prosthetics, and rehabilitation treatment robots.
