characteristics and development.
Methods: This paper reviews various productions and patents related to the nursing robot. The structural
characteristics, differentiations and applications of the typical nursing robot are also introduced.
Results: The three types of the nursing robot are compared and analyzed, and the typical characteristics
are concluded. The main problems in its development are analyzed, the development trend is foreseen,
and the current and future research of the productions and patents on the nursing robot are discussed.
Conclusion: Nursing robots are divided into an independent nursing robot, rehabilitation nursing robot
bed and multifunctional mobile nursing robot. The nursing robot has important practical significance
for promoting social nursing services, and it plays an important role in improving nursing quality of
patients and the elderly and reducing the pressure of nursing staff. Further improvements are needed in
the aspects of reliability, comfortable capability, humanization, intelligence and security of the nursing
